Peace has returned to Ninjago, and the Ninja have grown complacent. They are abruptly called back into action, though, when they receive reports that Lord Garmadon has returned. However, this just turns out to be his young son, Lloyd Montgomery Garmadon, up to mischief. The Ninja hold a tournament to decide between themselves who is destined to become the legendary ‘’Green Ninja’’. Meanwhile, Lloyd fortuitously discovers the Tomb of the Hypnobrai Tribe of the Serpentine and releases them, and they attack Jumanakai Village. It's up to the ninja to save it.

The Ninja have returned to training, preparing for the looming threat of the Serpentine. A mysterious falcon leads Zane to a treehouse, being built for Lloyd by the Hypnobrai. The rest of the Ninja arrive, confronting Lloyd and the snakes. However, they return to their Monastery to find it in ruins, after it was left unguarded. Zane, with the help of the Falcon again, soon discovers them a new home – a ship called the ‘’Destiny’s Bounty’’. Meanwhile, Lloyd is betrayed by the Hypnobrai.

Lloyd, bitter after he was cast out by the Hypnobrai, releases the Fangpyre Tribe from their tomb. Back on the Destiny’s Bounty, the Ninja begin to clean and prepare it to be their new headquarters and are visited by Jay’s parents – Ed and Edna. The Fangpyre attack the junkyard owned by Jay’s parents, and the Ninja encounter the Fangpyre for the first time. They must rush to save Ed and Edna from their transforming venom.

After the Fangpyres join forces with the Hypnobrai, Lloyd releases Pythor – the last of the Anacondrai Tribe. Pythor, pretending to be his friend, steals a map from him that shows where the two remaining snakes tribes dwell. Sensei Wu then takes Lloyd under his wing.

Lloyd moves in and pranks all the Ninja by beating Kai's high score on his game "Fist to Face 2", messing with Cole's violet berry soup, overriding Jay's sparring robot, and turning Zane's ninja suit pink, and he causes them to blame it on each other. Meanwhile, Pythor releases the Venomari and Constrictai Tribes from their tombs and plans to unite them under him. In the process, he steals the Sacred Flute. The Ninja go and foil the plan for unity, but are nearly captured. It is only Zane's pink suit that enables them to escape with their mission complete.

Pythor finds the ancient Serpentine city of Ouroboros. Meanwhile, the ninja get new ZX suits, but the mysterious Samurai X gives them trouble. Later, Pythor, through a devilish trick, declares himself to be the Snake King, the destined leader who will reawaken The Great Devourer – an ancient, seemingly immortal beast who will consume all of Ninjago. Lloyd sees this, but is discovered and imprisoned. The Ninja, captured by the Serpentine while trying to rescue Lloyd, are saved by Samurai X, but Kai shockingly discovers that Nya is the Samurai.

When the four Ninja follow the mysterious falcon into the woods, they stumble on a hidden workshop where Zane learns the secret about his past; he is a nindroid designed to 'protect those who cannot protect themselves', as said by his deceased father. The discovery of his past allows Zane to unlock his true potential. Meanwhile, Master Wu travels to the realm of madness to find Lord Garmadon.

Jay and Nya have to cut their first date in the Mega-Monster Amusement Park short, as the Serpentine arrive to retrieve the first of the four Fang Blades needed to awaken the Great Devourer. But Jay pricks his hand on the fang of a skeletal Fangpyre, triggering a transformation. While Jay and Nya go out for their date, the other three ninja attempt to stop Pythor and the Serpentine. Pythor retrieves the first Fangblade and Jay saves Nya from her death, having unlocked his true potential, while she reveals her Samurai X identity. Meanwhile, Wu finds Lord Garmadon, now with four arms, and warns him about Lloyd’s captivity.

The four Ninja go undercover as a dance troupe and enter a talent contest in their quest to win "The Blade Cup", in which one of the Fangblades is hidden, taken from its tomb by Clutch Powers. During this, Cole meets his father, the leader of one particularly famous dance troupe, the “Royal Blacksmiths” who, if anything, is bossier than Sensei Wu. At one point, Cole contemplates stealing the cup, but is berated by his father and decides to make him proud by performing and winning the cup. Pythor collapses the stage and steals the cup, while Cole finds his true potential and saves his father. Meanwhile, Garmadon returns to Ninjago with Sensei Wu.

The Ninja are suspicious when Lord Garmadon moves in to help search for his missing son, but realize they have to work together in their attempt to rescue Lloyd from the Serpentine while they dig for the third Fangblade in the heart of the Fire Temple. Kai, after being held back by his ambition to become the Green Ninja, reaches his true potential and rescues Lloyd. It is also revealed, though Kai's own realization, that Lloyd is the destined Green Ninja. This causes grief to both Wu and Garmadon, since their family has now been further divided. In the end, Kai gives a look of worry, realizing how complex it will be for Lloyd to fight his own father in the future.

At a suggestion from Lloyd to steal back the three Fangblades as Pythor goes for the fourth, the Ninja and Sensei Wu try to infiltrate the inner sanctum of the Serpentine and walk right into a trap. When Lloyd's rescue mission does not go as planned, there is only one person who can help them, namely Lord Garmadon. In the nick of time, Garmadon comes with the Skeleton Army and engages in a battle against Pythor and the Serpentine, allowing Lloyd to release the Ninja and get the Fangblades. Garmadon leaves Lloyd to follow his own path and the Ninja plan to destroy the Fangblades, but Pythor follows them in secret.

Upon arriving at Torchfire Mountain, the only place where the Fangblades can be destroyed, Pythor reveals himself and steals the blades back, leaving the Ninja to die. Luckily, Nya saves them. The four ninja, with Wu, Nya as Samurai X and Lloyd, haste to the lost City of Ouroboros to try to stop Pythor from awaking the Great Devourer, but it is a race against time. After a battle on a Serpentine Truck-fortress, in which Sensei Wu deliberately cuts himself off from the Ninja to face Pythor, all arrive at the city. At last, Pythor succeeds, but Sensei Wu forces him to see the power he has unleashed. They are then both consumed by the awakened Great Devourer.

Disaster threatens as the Ninja must fight to defeat the all consuming Great Devourer in a desperate attempt to save Ninjago. In the end, only Lord Garmadon, using the Four Golden Weapons with the elements of fire, ice, lightning, and earth, can destroy the Great Devourer. He manages to kill the snake and Wu is shown to have survived, but Lord Garmadon vanishes with the Weapons and Lloyd must accept the fact that he must face him one day.

The ninja help repair Ninjago City although they have lost their elemental powers. Nya informs them that she has found a real-estate agent who will help them find a place to live. Lord Garmadon persuades the Serpentine to follow him, and recreates the Bounty from its remains. The ninja find a luxurious apartment with a training-room and although it is expensive, they decide to get jobs to pay for the rent. Kai being a birthday ninja, Cole being a bank robber catcher, Jay being a pizza delivery guy, and Zane being a food cutter. However, when the Serpentine Generals are betrayed by the Serpentine by following Lord Garmadon, Jay is lured to a house less intersection, where he is kidnapped. The majority of the serpentine generals steal the money, but it turns out to be a diversion so that Skales can kidnap Lloyd. However, he is stopped and sent to jail, and then they settle for a lower-class flat. Lord Garmadon and the Serpentine fly to the Golden Peaks and he fuses the Weapons together into a Mega Weapon.

The ninja find "Grand Sensei Dareth's Mojo Dojo", where Dareth agrees to let them use it to train Lloyd. Lord Garmadon discovers Captain Soto's journal in the Bounty's cabin and accidentally resurrects the original pirate-crew of the Bounty using the Mega Weapon. Lord Garmadon realizes that the weapon only has the power to create, while the pirates lock him up with the Serpentine. The Ninja have started training Lloyd when the Pirates attack Ninjago City. Dareth, dressed as the Brown Ninja, jumps on ship but gets captured by the pirates. The Ninja go to his rescue and Lloyd does Spinjitzu for the first time. The pirates are arrested, but Lord Garmadon takes back the Bounty.

The Ninja receive a message from Lloyd's old school, Darkley Boarding School, inviting him to receive an award. Meanwhile, Lord Garmadon creates evil impersonations of the Ninja to deal with them. The Ninja arrive at the school and are surprised to see none of the students or teachers. Indeed, the whole award is revealed to be a trap and the Ninja are locked in a room with all the teachers, and Lloyd is tied up. Meanwhile, the clones learn the location of the Ninja from Nya. At the school, the Ninja find a way out of the room, but the clones arrive and begin fighting them. Lloyd persuades his former classmates to reveal their inner good self and join him. With their help, the Ninja are able to defeat the clones.

Lloyd is training in Dareth's dojo when a wrecking ball crashes through the wall. It is revealed that Dareth has fallen behind on his payments and a company named Darnagom will buy the dojo, but Zane discovers Garmadon's part behind this being that Darnagom is Garmadon arranged. The Ninja learn of the grand prize of the Ninjaball Run, the most dangerous race in Ninjago, and decide to enter the race. The next day, the race starts promising indeed. Garmadon enters the race with the "Bounty" to prevent them from finishing, but the Ninja manage to finish first followed closely by Garmadon, while Lloyd takes the "Bounty" back for the Ninja.

Lord Garmadon arrives at the museum planning to revive the extinct Grundle to hunt the Ninja. The Ninja interrupt his plan, but are affected by the power of the Mega Weapon and turned into kids. Moreover, the Ninja realize the Grundle must have been revived after all and escape the museum. The Ninja call Lloyd to meet them and inform him of the situation. Lloyd calls Master Wu and Nya back at the Destiny's Bounty, telling them what happened. Then, the Grundle shows up and is about to consume the Ninja, when Master Wu and Nya arrive with some Tomorrow's Tea, tossing it to them. Lloyd uses the tea to defeat the Grundle, but while the Ninja are returned to normal, he has aged as well.

After the Ninja foil his latest plan, Lord Garmadon uses his Mega Weapon to go back in time and prevent the formation of their team. Unknown to him, the Ninja have come with him back to the day Kai met Sensei Wu. After failing to alter the timeline by stopping Nya's kidnapping, Garmadon teams up with his past self and amboushes the past Kai in the Fire Temple. The present Ninja arrive and fight back, before realizing that by destroying the Mega Weapon the timeline will be restored. Using the past Golden Weapons, they destroy the Mega Weapon erasing it from existence and memory and restoring the timeline.

Garmadon, now powerless, returns to the City of Ouroboros to plan his search for the legendary Dark Island, but the Serpentine soon betray him, pushing him into the sea by a helicopter while Skales is declared their leader. Meanwhile, the Ninja meet Misako, Lloyd's long lost mother, who tells of the existence of the Overlord and his indestructible Stone Army. At the same time, the venom of the Devourer brings a huge Stone Warrior to life, but the Ninja trick him into toppling down a bottomless pit. Meanwhile, Garmadon washes up on the Dark Island, where he meets and teams up with the Overlord.

Skales is crowned the new Snake King and plans to dig the foundations of Ninjago City, bringing it down into chaos. However, the Serpentine discover a secret vault where the Stone Army rests, before the Great Devourer's venom melts through the roof and brings the statues to life. They defeat the Serpentine and trap them inside. Then, they rise up to the city which begins to evacuate. Meanwhile, on the Dark Island, Garmadon is guided by the Overlord to an ancient clock and he dons the Helmet of Shadows, starting the clock's countdown to the Final Battle.

On the Dark Island, the Overlord tells Garmadon that they need a Super-Weapon unlike anything ever seen. Back in Ninjago, Zane sends his falcon to investigate the island. Misako tells the Ninja of the Temple of Light, where they can obtain powers to defeat the Stone Army. They set sail for the Dark Island on the Bounty, but the ship is then struck by a storm and eventually runs aground on an uncharted island with a lighthouse. There, the Ninja find Zane's father, Dr. Julien, who explains that Samukai brought him back to life, forcing him to construct the Skeletons' war machines. Dr. Julien repairs the Bounty, and they all continue their journey to the Dark Island.

The Ninja arrive on the Dark Island and search for the Temple of Light, while Dr. Julien and Nya build new vehicles for them. Then, the Ninja infiltrate Garmadon's camp and Jay locates the temple. After escaping, the Ninja head for the temple, where they are gifted with Elemental swords and kimono, and with their new powers, the Stone Army is defeated.

Misako reveals that there might be a way of avoiding the Final Battle: returning the Helmet of Shadows to its pedestal. The Ninja escort Misako into Garmadon's camp impersonating Stone Warriors, where she manages to steal the helmet, but they are spotted and Garmadon, enraged, uses a giant robot to chase after them. The Ninja get to the Celestial Clock and try to find the Helmet's pedestal, but are too late. The countdown has ended, the Stone Army captures Nya and the Ninja are sent down into a crevasse. The Overlord shows Garmadon the completed Super-Weapon which he named Garmatron.

The Ninja return to Garmadon's base but find it deserted, as everyone has left for the coast to use Garmatron to upset the balance between good and evil. The Ninja follow, but are stopped by Nya, polluted with Dark Matter. They eventually overcome her and reach the coast, but Garmadon uses Garmatron, infecting the balance. The Overlord then betrays Garmadon, possessing him and attacking Lloyd. Lloyd tries to bring back his father, but the Overlord defeats him, breaking his leg and wrecking the Bounty. The Overlord then opens a portal to Ninjago City and goes through with the Garmatron and his forces, leaving the Ninja stranded on the Dark Island.

As the Overlord conquers Ninjago, the Ninja return to the Temple of Light, where they find the First Spinjitzu Master's battle mech. With the arrival of the Ultra-Dragon, the group flies back to Ninjago City, which is now possessed by Overlord, who has morphed into a dragon. The Ninja fight the Stone Army, but in the end, they are saved by Dareth, who uses the Helmet of Shadows to control the army. The Ninja climb the tower where the Overlord is, but all of them except Lloyd are forced to remain behind. Facing the Overlord, Lloyd summons the Golden Dragon and defeats him, freeing the city from his control. Lord Garmadon then emerges, purged of all corruption within him.

The Ninja team breaks up and goes their separate ways after the loss of Zane. Lloyd reunites them. Shortly after reuniting, however, they receive a message that Zane is alive and the Ninja must compete in Master Chen's sinister Tournament of Elements if they wish to see him again. Sensei Garmadon, having a feeling that Chen is up to something, accompanies the Ninja on their journey to Chen's island. On Chen's ship, the ninja discover that they aren't the only ones with elemental powers, as there are other descendants of elemental masters such as speed, metal, smoke, nature, gravity, mind, light, etc.

After the ninja arrive at Chen's island, Garmadon tells them he used to train under Chen before they became enemies. When inside, Chen himself greets the Elemental Masters, and explains the rules of the Tournament of Elements: obtain a Jade Blade to move on. In the end, Karlof becomes the first Elemental Master to lose. Later, as the ninja search for Zane, they accidentally stumble into a secret gathering of Chen and his cultists just in time to see Chen steal Karlof's powers. They end up learning that the tournament is about Chen stealing everyone's elemental powers.

Zane, who is now titanium, has lost his memory, but regains it after meeting P.I.X.A.L. in another room. He discovers P.I.X.A.L. has been scrapped but Zane puts her hard-drive inside his head, becoming compatible with her. However, Clouse catches and tasers him. Meanwhile, the tournament continues: Griffin against Gravis, Neuro against Bolobo, and Kai against Ash. Griffin, Neuro, and Kai move on. Clouse pits Jay and Cole against each other in a fight. The Ninja try to get help from Neuro, but he fails to break into Chen's quarters. Luckily, he discovers that Chen is planning to steal everyone's powers for a spell. Cole and Jay fight each other and eventually, Cole gives up the Jade Blade to Jay and loses, getting kicked out of the tournament. This ends their long rivalry over Nya for good.

After Jacob, the Master of Sound, loses to Skylor, he is brought to Chen's underground factory, where Cole, who is now powerless, tries to find a way to escape. Clouse catches Jacob trying to escape and makes him an example of feeding him to his serpent, the second-largest snake in Ninjago. Meanwhile Cole finds Zane locked up and promises to get them both out. In the meantime, Nya uses her new vehicle to locate Chen's island to find the ninja, but Dareth ends up coming along. Meanwhile, Master Chen stages an event called Thunderblade, where two contestants wear roller skates and attempt to make as many laps as possible while carrying a Jade Blade, while the others can help either side. Lloyd and Camille, Master of Form, are pitted against each other for the event. The ninja spread the news about Chen's staff and everybody switches to Lloyd's side to overwhelm Camille. At the last moment, Camille crosses the finish line before Lloyd, but ends up dropping her Jade Blade. Against overwhelming odds, Lloyd and the ninja win and earn the trust of several other contestants.

The Ninja form an alliance with the Elemental Masters after convincing them of Chen's true plan. Chen responds by spreading the rumor that he has a spy within and the Elemental Masters interrogate each other with no results, weakening the alliance. Meanwhile, Nya enters Chen's palace, disguised as a Kabuki, and steals page 149 from Clouse's spell book, which is revealed to turn Chen's followers into Anacondrai. During this time, Cole and Zane attempt to break out of Chen's factory.

With Clouse's spell page in Nya's possession, Chen discovers her on the island. He explains to the fighters that whoever finds Nya wins the tournament altogether. Lloyd learns how to create a dragon without his Golden Power and, along with his father, stumbles upon the place where a great battle between the Elemental Masters and the Anacondrai took place, and Garmadon tells Lloyd the story of how Master Chen convinced both sides to declare war. In the war's aftermath, the Anacondrai Generals were banished to the Cursed Realm while the remaining Serpentine were locked in tombs. Meanwhile, Chen reveals his true goals, capturing all the Elemental Masters except for Lloyd (Lloyd did not take any "gift" from Chen). Skylor is also revealed to be Chen's spy and daughter.

With the Elemental Masters except Lloyd captured, Chen steals their powers and now needs Lloyd's power to complete the spell. Skylor tells Chen about Kai and Chen spares him, while Jay and the other fighters are taken to the factory. Meanwhile, Cole, Zane, and Karlof lead the imprisoned Elemental Masters into escaping the factory by building a Roto Jet. Chen has Kai betray Lloyd and trick him into battling Chen, where he uses all the other Elemental Powers against Lloyd, defeating the Green Ninja and stealing his powers. However, Kai and Skylor take Chen's staff and destroy it, giving the powers back to the Elemental Masters.

Although all the Masters have their powers back, Clouse discovers that Skylor's power of Amber can still be used for the spell. Garmadon, Nya, and the Ninja go to find Skylor. Kai manages to find her and help her escape, but they get captured. Clouse battles Garmadon and tries to banish him to the Cursed Realm, but Garmadon escapes and Clouse gets banished instead. Chen manages to complete Clouse's spell without him, turning himself, his followers, and everyone who has the Anacondrai symbol on their back (even Skylor and Garmadon) into Anacondrai. Then, he sends his army by air back to Ninjago. Meanwhile, Kai and Skylor escape. The Elemental Masters learn from Zane that they have the power to create their own dragon and follow Chen and his army.

With Chen's Anacondrai army on the loose, the Ninja visit Kryptarium Prison, where they meet Pythor, who is still mini-sized and ask for his assistance. Coincidentally, Master Chen has learned the spell has temporary effects and only the essence of a true Anacondrai can make it permanent and goes to the prison to capture Pythor. Then, he sends all of his army with noodle trucks at various locations, and the Elemental Masters follow them to stop them. However, it turns out to be a huge trap, as Chen is already attacking Ninjago with his full force.

The Elemental Masters discover there's a strategic location called the Corridor of Elders where they can make their last stand against Chen's Anacondrai army. Pythor escapes Chen's clutches and discovers there is a spell to release the spirits of the Anacondrai Generals from the Cursed Realm and end the war. However, this must be done at a serious cost. Garmadon banishes himself to the Cursed Realm in order to release the spirits, and they banish Chen and his army as well. Skylor, who turns back to normal, decides to run her father's noodle business. The Ninja burn the Spellbook and pay tribute to Garmadon. They build Garmadon's statue on the Corridor Of Elders. At the end of the episode, Morro escapes from the Cursed Realm, foreshadowing the following season.

Lloyd is called for help at the museum, but he realizes that it was a trap set by Morro, a ghost who escaped the Cursed Realm and possesses him. The other Ninja lose their elemental powers as a result. After possessing Lloyd, Morro steals the Allied Armor and goes to Sensei Wu's tea shop to get the staff that was given to him by the First Spinjitzu Master. The Ninja and Wu escape on the Destiny's Bounty, but realize they are being followed by Morro, who uses Lloyd's elemental dragon. Wu reveals to the Ninja that Morro was his first student, and the Master of Wind.

As the Ninja escape on the Destiny's Bounty, Morro boards the vessel and tries to get Sensei Wu's staff, but Wu throws his staff overboard and Morro goes after it while the ship crashes. The Ninja then learn that the staff had three clues to where the First Spinjitzu Master's tomb is, and when they realize that a thief named Ronin stole the Scroll of Airjitzu, the first clue, they go to Stiix, a city built on water, to get the scroll from him. On the way there they are attacked by a ghost that Morro summoned with the Allied Armor, but the Ninja defeat him, discovering that water can kill the ghosts. Meanwhile, Wu tells Nya she must train to become the Master of Water, just like her mother did before her and like how Kai's father became the Master of Fire before him.

The Ninja try to make a bargain for the Scroll Of Airjitzu with Ronin, but the price is too high. They try to earn some money, but their lack of coordination results in an utter disaster. Morro steals the scroll in the end, and escapes having learned Airjitzu, but Ronin gives the Ninja weapons to kill ghosts. Meanwhile, Sensei Wu trains Nya to control water, and discovers that her weakness is feeling weak.

While the Ninja have their fears tested in the haunted temple of the evil Sensei Yang, in another attempt to claim the Scroll of Airjitzu, Nya pays Ronin to take her to her Samurai X cave where they encounter Morro and his ghosts who are after Nya's samurai suit. Nya accepts that she is the Master of Water after she makes it rain in the desert while being chased by the ghosts. Meanwhile, the Ninja get the Scroll Of Airjitzu, but as they try to make it out of the temple to escape a curse, Cole accidentally drops the scroll, causing him to get turned into a ghost when he chooses to retrieve the scroll rather than escape.

The Ninja must travel to the Cloud Kingdom for the Sword of Sanctuary, the second clue on Wu's staff. To get there, they must climb the tallest mountain in Ninjago and jump into a cyclone that passes over. While climbing, the Ninja encounter an avalanche, but thanks to Cole's new ghost abilities, they manage to escape the avalanche. Eventually, they get to the Cloud Kingdom by using Airjitzu successfully and Morro gets there in time to see them leave. Back at the Bounty, Sensei Wu and Nya capture Ghoultar and demand answers from him.

The Ninja arrive at the Cloud Kingdom, where they begin their search for the Sword of Sanctuary, but are deceived by Fenwick, who has formed an alliance with Morro and let him into the Kingdom. In the meantime, Wu, Nya, Misako, and Ronin interrogate Ghoultar on the Bounty. Back at the Kingdom, Morro manages to obtain the sword, but the Ninja pursue him back through the cyclone and down the mountainside in Ninjago. All of the Ninja board the Bounty except Kai, who stays behind and takes the Sword of Sanctuary from Morro as Lloyd temporarily regains control of his body. The Ninja fly off into the sunset, ready for the next step of the mission.

The Ninja now have all the items they need to get to the tomb of the First Spinjitzu Master, but before they can figure out the last clue that leads to the location of the tomb, Ronin steals the Sword of Sanctuary to give it to Morro in exchange for his cursed soul. Morro takes possession of Ronin to trick the Ninja into travelling to the Caves of Despair before trying to bury them alive. The Ninja escape and Ronin tries to repay them by entrusting them with the real location of the tomb, which is under the ocean.

The Ninja reach the underwater tomb with Ronin's vehicle and manage to survive two protection trials, before encountering Morro. Morro gets trapped and the Ninja find the Realm Crystal at the tomb of the First Spinjitzu Master, but Morro arrives and demands the Realm Crystal in exchange for Lloyd. Kai tricks Morro, but when the Ninja rush off to save Lloyd, Morro manages to obtain the Realm Crystal, which he uses to open a portal to the Cursed Realm and escape.

Part I: The Ninja go to Stiix to try to stop Morro from unleashing his master, the Preeminent. They manage to fend off many ghosts, but when Lloyd gets to Morro, the ghost tries to reason with him, using Lloyd's father as an example. Lloyd hesitates, giving time for the Preeminent to be unleashed, while he goes to the Cursed Realm.

Part II: The Ninja must protect Stiix from the Preemiment, but the beast is invincible. Meanwhile, Lloyd uses his father's help to get himself out of the Cursed Realm, and fights Morro across multiple realms, including a realm called "Chima", trying to trap him, eventually managing to do so. The Ninja get on a boat with the people of Stiix and Nya is able to unlock her true potential, creating a wave that drowns the Preeminent. Sensei Wu tries to save Morro, but the ghost feels remorseful and willingly drowns and is erased from existence, having given Wu the Realm Crystal. Using the crystal, the Ninja bring back Lloyd from the realm he was left in and he decides to follow in his fathers' footsteps and train people.

This episode includes a crossover with Legends of Chima.

Following the destruction of the Cursed Realm and the ultimate death of all its prisoners, the Ninja have found sudden fame for their roles and actions. Yet, amid their newfound popularity, a new threat is posed when a survivor of the Cursed Realm's destruction, Clouse, loiters in Ninjago to wreak further havoc. The Ninja attempt to stop him, but they are ultimately subdued and unable to do so. Clouse heads to Stiix, where he finds the ancient Teapot of Tyrahn, which contains a deceptive Djinn named Nadakhan who imprisons Clouse in the teapot following his release. As the Ninja arrive in Stiix, they discover they have been framed for a series of crimes and are pursued by the city's inhabitants. In the meantime, Nadakhan finds out what has happened to his crew of Sky Pirates, and eventually captures Sensei Wu after accidentally being summoned by him.

The Ninja are declared to be the Public Enemy Number One after being framed by Nadakhan for crimes they did not commit. Ronin offers to capture the Ninja in exchange for a 'clean slate,' meaning all of the crimes he committed, will be undone. Meanwhile, Misako is captured by Nadakhan. The Ninja devise a plan to separate into pairs so that they can't all be arrested. However, at the library, Ronin hacks into Zane's system and shuts him down, and then captures Lloyd. When Kai and Nya find out what happened to Zane and Lloyd, they spot Ronin, who goes after them and tricks them into getting caught. Jay and Cole go to Mega Monster Amusement Park where Zane was framed, and Ronin chases around them around the park and finally captures them. The Ninja are then brought into custody, and eventually, they are taken to Kryptarium. Nadakhan steals the Realm Crystal from a maze built by Cyrus Borg called Hiroshi's labyrinth.

The Ninja get 'special treatment' at the Kryptarium Prison, and the Mechanic wants to use Zane for spare parts. Nadakhan brings his crew back from other realms: Flintlocke, Clancee, Doubloon, Monkey Wretch, and Dogshank. The Ninja start a food fight and befriend Soto, the captain who trapped Nadakhan into the Teapot of Tyrahn and told the Ninja how to stop Nadakhan: Tiger Widow venom, and bust themselves and Soto out of Kryptarium. Nadakhan visits the Kingdom of Djinjago realm and finds out that when the Ninja destroyed the Cursed Realm, this realm and kingdom started to collapse. He promised to avenge the people of his Realm and Kingdom. The Ninja find out that the map is in a lantern aboard the Misfortune's Keep.

The Ninja are undercover in the Police Station. Nadakhan visits Jay, making him use his wishes, and he finds out that he was adopted. The Sky Pirates attack the city, and the Ninja try to stop them. Kai gets captured by Nadakhan, while the rest of the Ninja get the Lantern. The land gets stolen by the Sky Pirates to rebuild the Kingdom of Djinjago.

The other Ninja travel by boat to a dangerous island, but during the journey, there is a lightning storm, and Zane goes below deck and finds Nadakhan, who tricks Zane into wishing himself away. When the Ninja arrive, they wondered how Jay got a mansion and a stylish boat, so when Cole tells that he saw Nadakhan, the Ninja make Jay retrieve the Tiger Widow Venom, but when Nadakhan finds out that the Ninja is getting the only thing that can stop him, he ambushes the Ninja, but when Jay successfully gets the venom, Nadakhan teleports to Jay and empties the canister of venom. With it being the last one, they don't have another chance to get another dose of the venom, and Nadakhan captures Jay, but Nya reveals that Nadakhan emptied the wrong canister, giving the Ninja another chance at stopping Nadakhan.

Held captive on Misfortune's Keep, Jay is tested as Nadakhan does everything in his power to break the Ninja's will to say his final wish. Meanwhile, Lloyd, Nya, and Cole are stuck on Tiger Widow Island, with no way to get off, so they decided to build a raft to get off. Back on Misfortune's Keep, Jay has dinner with Nadakhan, telling the Lightning Ninja that if a Djinn Prince/Princess marries on Djinn Land, under the Djinn Law the prince/princess will get infinite wishes. Jay tries telling Flintlocke, but Nadakhan thinks he is telling fibs, and the first-mate believes him, so they decided to put Jay in a dangerous game: Scrap 'n' Tap. The winner gets to tap out. Nadakhan kept convincing Jay to 'wish it all away,' but since he's smart, Jay stays in the game, although losing to Monkey Wretch, Doubloon, and Dogshank. After the match, Jay is locked in a hole, having a bruised eye. Clancee, being the kind-hearted one, gives the Ninja some food (to which he declines) and an eyepatch to make the pirate look. Jay then realizes that part of his future was coming together. Then Flintlocke comes in and gives Jay the key since his speech made him realize something. After escaping, Jay walks into Nadakhan's room, to find the Djinn Blade, only to find out it was fake. Also, the Sky Pirates were behind Jay, making this all a plan! The Police Commissioner, Ronin, and detectives Simon, and Tommy save Nya, Lloyd, and Cole from Tiger Widow Island. The Commissioner then says he was wrong to distrust the Ninja; Ronin then tells the three that Jay sent a message, and set off to save him.

The last remaining Ninja dare to infiltrate the Sky Pirates in an attempt to save Jay and defeat Nadakhan once and for all, using movie magic. Kevin and Dan suggest that the 3 Ninja disguise themselves as Sky Pirates to sneak the poison on Misfortune's Keep, and pass undetected by speaking pirate dialect, apart from Lloyd, who seems to be horrible at talking pirate. They start building a Raid Zeppelin, the blueprint Jay wrote his message on. Once learning pirate talk and disguises as pirates, the Ninja set off to the re-constructing Kingdom of Djinjago realm. Cole climbs onboard, nearly dropping the venom. He secretly walks across the deck, using his disappearing skills. When Cole got to the drinks section, Jay comes out with a vengestone ball and chain, wearing his eyepatch from the Scrap 'n' Tap. Jay asks why Cole's dressed like a pirate but avoids it. Jay then apologizes for not telling the truth earlier, and Cole apologizes for not being a better friend. Nadakhan comes in to find out that the prisoner escaped, and attempts to find him. As he exits, Jay and Cole get this chance to get out, leaving the venom behind. When the two use Airjitzu to climb on their built Raid Zeppelin, they've been put as prisoners, along with Lloyd and Nya. After that, Nya was invited by Nadakhan to have sweet food, but Nya declines, saying she wasn't 'much of a sweet tooth.' The djinn says that if she marries him, he'll get infinite wishes. Nya then says that if he frees her friends, she'll think about it. However, things get a bit hectic when wishes are fired everywhere, such as Lloyd being wise like Wu, Nya wasting two of her wishes, and Cole wishing that Nadakhan didn't have the sword. Soon enough, Lloyd sends Jay and Nya off the clouds and eventually, he and Cole get sucked into the Djinn Blade.

With only Nya and Jay remaining, they set off to the lighthouse, where they think that Nadakhan won't find the two there. But, when Nadakhan forced Clancee to wish where they were, he finds that he has sailed enough oceans for that to be the Red Kelp of the West Apasso Current. After meeting Echo Zane, the two decide to spruce the place up, having traps set up, weapons, etc., and wait for night. However, Echo spotted the Sky Pirates approaching. During their previous discussion for Jay's last wish, Nya tells him he has to wish for Nadakhan not to be a djinn. A massive fight scene goes on, with most of the Traveller's Tea gone. When they found it in an isolated place, Jay and Nya try to talk it out about who goes to the portal, since it was only big enough for one. Nya tells Jay that she also saw her future: the first time she met Jay. She then continues, saying that Jay has the last wish, and she throws him in the portal. Nya fights alone against the pirates, but fails, and is eventually captured.

When Jay is back in Ninjago City, he starts to gather allies: Captain Soto, Skylor, the Police Commissioner, Ronin, Echo Zane, and Dareth. They make a plan called Operation Land Ho, but when Bucko and Squiffy have heard what they said, they report back to Nadakhan, warning him about Jay and the others. Nya convinces Nadakhan to drop his sword, allowing Jay to grab it and enter the Djinn Blade to rescue Sensei Wu, Misako, and the other Ninja.

When the marriage takes place, Nadakhan has been given the power of infinite wishes. The crew realizes that Nadakhan only wants his power all for himself, so Clancee tells Jay where the Tiger Widow Venom is. Nadakhan banishes Clancee, Doubloon, and Monkey Wretch, but Dogshank and Flintlocke escape and decide to unite with the Ninja against Nadakhan. Jay gives the venom dart to Flintlocke while the Ninja confront Nadakhan and Nya, who has become a reincarnation of Nadakhan's true lover, Dilara. The Ninja attempt to get Nadakhan out in the open so he'll be exposed to Flintlocke's dart, and eventually they succeed in doing so. The dart hits Nadakhan but hits Nya as well. Being the deadliest venom, it kills her, so Jay uses his final wish to wish that no one had found the Teapot of Tyrahn in the first place, which eliminates the entire events of Skybound, and also results in none of the Ninja except for Jay and Nya remembering the events that occurred. The season ends with Jay and Nya embracing in a romantic hug, while the other Ninja look on.

On the Day of the Departed, Cole realizes his ghostly form is fading away, so he goes to Yang's Temple, but accidentally opens a passage to the Departed Realm, reviving the Ninja's old enemies (Samukai, Pythor, Kozu, Cryptor, Chen, and Morro) via mannequins in the Hall of Villainy. Yang orders the villains to go after the Ninja and curse them to take their place in the Departed Realm. Cole finds that Yang is trying to resurrect himself using the Rift of Return. Morro, instead of fighting Wu, warns him of Yang's plan. The Ninja defeat their adversaries, reunite and set off to Yang's temple. Yang tells Cole he wanted to be immortal so he wouldn't be forgotten, but Cole assures Yang he'll be remembered as the creator of Airjitzu. Cole crosses through the rift and becomes a human once more, but the rift almost closes the moment he crosses through it, giving him a ghostly green scar on his face.

At the ruins of the Monastery of Spinjitzu, a strange vortex opens up to admit a mysterious hooded warrior who is then confronted by Master Wu; the pair recognize each other and Wu reveals that it has been forty years since he last encountered his enemy. Elsewhere, Misako is unloading supplies at the Temple of Airjitzu with the assistance of Ronin and of Dareth, while the Ninja are helping Dr. Saunders at the museum. While there, Kai and Nya find a portrait of their long-missing parents, Ray and Maya, and the Ninja also discover a portrait of a battle between Wu and Garmadon and the "mythical" Hands of Time, Acronix and Krux. Acronix, who happens to be Wu's mysterious enemy, is defeated but then restarts the battle after a Time Blade emerges from the vortex, causing a temporal wave that draws the Ninja to the monastery after Acronix strikes Wu with the weapon. During the ensuing battle, Acronix reveals that he knew Kai and Nya's father and then escapes after faking his own demise. He then meets up with Dr. Saunders, who is revealed to be none other than Krux.

Wu, still recovering from his battle with Acronix, reveals to the Ninja that the Hands of Time were once Elemental Masters of Time who turned on their comrades after the Serpentine Wars. After a series of battles, their powers were drained into the four Time Blades, which were then sent into the time vortex and followed by Acronix and Krux themselves. Believing both to have been destroyed, the Ninja set to work unpacking their belongings into the Temple of Airjitzu, with Nya expressing some regret over leaving behind her Samurai X costume. Meanwhile, the reunited Acronix and Krux embark on their plan to conquer Ninjago, which involves unleashing the sixth tribe of Serpentine, the Vermillion warriors, snakes who join together inside armor to form humanoid warriors. One is sent to abduct Cyrus Borg at his new product launch, and two more are unleashed when the Ninja arrive to save him, with Acronix and Krux abducting Borg after Zane tries to take him to safety. The Vermillion keep the other Ninja occupied.

As Acronix and Krux unleash more Vermillion, including Commanders and Generals Machia, Blunck, and Raggmunk, the Ninja split up in an effort to determine what is behind the latest menace to Ninjago, which includes the kidnapping of various craftspeople from around the city. Cole, Jay, and Nya take the inactive Zane back to the Samurai X Cave in hopes of repairing him, and soon discover that Acronix is still alive and in league with Dr. Saunders. Kai makes the same discovery after visiting Saunders at the museum with a piece of Vermillion Tribe armor, as well as learning that Saunders is Krux. The villain also claims that Kai's parents sided with him and Acronix during their conflict with the Elemental Masters. Nya then arrives to back Kai up against the Time Twins, but the villains escape with Cyrus Borg using the Time Blade Acronix used against Wu.

Wu confesses to Misako that Acronix's attack on him at the monastery has accelerated his aging process, telling her to keep it secret, while Nya continues her attempts to repair Zane and frustrates P.I.X.A.L. with her lack of progress. With Wu out of action Lloyd tries to rally the Ninja out of guilt for not being for him at the monastery, while Kai continues to struggle with Krux's claim that his parents were traitors. The Vermillion raid Ninjago city in search of metal, and Kai takes Cole and Jay off to confront them in defiance of Lloyd's orders and are joined by Ronin, Dareth, Nya, and Zane, the latter still malfunctioning. In an effort to prevent their interference, Commander and General Machia sends a group of Vermillion to shut down Ninjago City's power, and after a talk with Wu, Lloyd joins his teammates, who succeed in restoring the power. Learning that the Vermillion Tribe are attacking Mega Monster Amusement Park, the Ninja leave to confront them, though a repaired Zane notices with some concern that P.I.X.A.L. is not responding to him while Jay takes off on his own after realizing that the Vermillion Tribe will undoubtedly be attacking his parents' junkyard as well.

The Ninja, except Jay, face off with the Vermillion at the amusement park while Jay goes to the aid of his parents as their scrapyard is invaded. However, the arrival of a second Time Blade changes things, with the Vermillion being directed to retrieve it after the technology loving Acronix pinpoints its location using his new Borg Watch, to the annoyance of his innovation-hating brother Krux.Two groups of Vermillion Tribe set out, with the scrapyard group abducting Jay's mother as well as stealing a large supply of metal, and manage to reach the Time Blade first. Its powers allow them to hold the Ninja at bay until Jay arrives with his new bike, which he has put together with help from his father. The Ninja succeed in recovering the blade and escaping on the bike and the Ultra Sonic Raider jet, but Machia and the Hands of Time are determined to take it back.

Having returned to the Temple of Airjitzu, Jay, Cole, and Zane are letting their success in retrieving the second Time Blade go to their heads. While Lloyd fears reprisal from the Time Twins, Kai mulls over the supposed treachery of his parents, and Nya continues to wonder about her missing Samurai X gear. Wu gets up and supports Lloyd's fears.He recognizes a symbol branded in the Tribe of Vermillion helmets that have been retrieved previously. Before he can expand on it, however, the Temple is attacked by the Hands of Time and their Vermillion warriors. As his teammates try to fight them off, Lloyd uses his dragon to attack the forces on the ground, only for it to dissipate due to his fear. He is then unexpectedly saved by the Samurai X Mech, revealing that the Vermillion Tribe were not responsible for the theft of Nya's equipment after all. Both the mech and the Destiny's Bounty are shot down, and the Hands of Time succeed in capturing the Time Blade and Wu before departing.

With the Bounty wrecked, the Ninja are forced to take separate vehicles as they set out to locate Wu and their enemies.Cole takes the Titanium Tumbler, Jay takes his bike, Kai and Nya take their old bikes, and Lloyd and Zane use the Destiny's Shadow, a flying boat given to him by Misako. Misako also reveals that Wu is rapidly aging, while Kai realizes that the mark on the Vermillions' helmets is his father's blacksmith brand. He and Nya thus set out separately to find answers. He returns to their family shop and discovers a hidden chamber concealing a strange two-bladed dagger and evidence that his parents are alive, while she returns to the Samurai X Cave and finds the thief of her suit, who changes their voice to sound like different people, such as Dareth, Ronin, Misako, or Garmadon. In the end the Samurai's conviction and skills are enough that Nya agrees to relinquish her identity, though she insists on the new Samurai X changing their color scheme; she also comes to believe that Skylor is the one in the armor, but is subsequently proven wrong after finding her with Kai. Meanwhile, the other four Ninja search the sewers of Ninjago for the Time Twins' lair after discovering their lab and run into several Serpentine led by Skales, who reveals that the Vermillion are the children and pure first generation progeny of the Great Devourer.

Having reassembled, the Ninja head into the underground swamp where the Vermillion Tribe have been bred in order to rescue the captured laborers, Wu, and Cyrus Borg, while Kai is determined to track down and confront his father. Zane, still struggling with P.I.X.A.L.'s absence, searches for Borg while Lloyd goes after Wu. Cole and Jay find the prisoners, including Karlof, Lou, and the Royal Blacksmiths. Lloyd soon finds Wu under guard by Raggmunk and Blunck, who are bemoaning Machia's recent promotion over them, and attempts to rescue him but fails. Cole and Jay attempt to rescue the various craftspeople, while the third Time Blade returns to Ninjago and is retrieved by the Time Twins. Meanwhile, Kai confronts his father believing him to be a traitor, only to be stopped by his mother and Nya, and then to learn that Krux, after returning to Ninjago alone, forced them into aiding his plans for conquest. They explain that these plans include a monstrous weapon known as the Iron Doom, which combines Ray's blacksmithing knowhow with Cyrus Borg's technology and the Time Blades to travel through time, which the Time Twins intend to use to conquer all of time. Unfortunately, before they can act to stop it, the Time Twins and their forces arrive and inform Kai and Nya that they will help them to retrieve the final Time Blade from its hiding place.

With no other hope of saving Wu, Kai and Nya are forced to enter the sunken library of Hono Mizu in the Boiling Sea, a volcanic region where their parents hid the Reversal Time Blade. Using their father's Dragon Blade, they combine their elements to form a Fusion Dragon and enter the dangerous environment, where they face numerous obstacles. Meanwhile, Lloyd and the others set out to rescue Cyrus Borg, only to learn that he has rigged a self-destruct feature on the Iron Doom. In an ensuing battle with Blunck and Raggmunk's Tribe of Vermillion warriors, the Ninja are joined by Samurai X, who has arrived seeking to save Borg as well after hacking into Zane's sensors. Kai and Nya succeed in retrieving the blade, only to lose it to Acronix and Krux after Ray is struck with a Time Punch. Kai, Nya, their parents, and Wu are then left falling to their doom but survive by forming the Fusion Dragon yet again. The Time Twins return to their base, and after thwarting Borg's sabotage order all their forces into the Iron Doom, which then enters a temporal vortex with the Fusion Dragon in hot pursuit.

Left in the present, Ray and Maya meet up with Borg, Samurai X, and the remaining Ninja while Kai and Nya have boarded the Iron Doom with Wu in hopes of stopping the Time Twins and retrieving the Reversal Blade. The villains' plan is soon revealed as the Iron Doom arrives in Ninjago's past just after the Time Twins' original defeat at the hands of the Elemental Masters, who are soon attacked by the Vermillion. Doing their best to mitigate any damage to the past without causing more, Kai and Nya then impersonate their parents to join young Wu and his allies in battle, only for the Vermillion snakes to merge with Iron Doom itself and give it the power of motion. They soon achieve victory over the past Elemental Masters, resulting in a present where no technology exists and where Ray's health continues to deteriorate as he ages rapidly. Kai and Nya form the Fusion Dragon once again to attack, but Kai is defeated after Nya leaves on an unspecified errand. However, the Hands of Time decide to depart for the distant future so that they won't have to continue dealing with their interference. Having found the Reversal Blade in the past prior to its being hidden in the Boiling Sea, Nya uses it to restore Wu's health, and with Kai's help they use it to reverse time, enabling them to board the Iron Doom while leaving the Reversal Blade with young Wu. A battle aboard the Iron Doom ends with Wu removing the Reversal Blade, which sets the Iron Doom adrift in time, and giving it to Kai and Nya, who are then dropped in the present where they use it to save their father. They then realize that Wu has been lost in time on the Iron Doom, staying aboard to deal with Krux and Acronix. The Ninja then turn to Lloyd, who is declared their new master. He explains that they must get rid of the Reversal Blade before turning their energies to finding Wu wherever he may be in time.

A year has passed since Master Wu was lost in time and the ninja are spread across Ninjago but regroup when a powerful relic is stolen by a group of masked criminals called the Sons of Garmadon. Lloyd finds that the group has something to do with his father, Lord Garmadon. Learning about the importance of the stolen 'Oni Mask' they are asked to protect the Royal Family and their Oni Mask from the Sons of Garmadon.

Lloyd and Princess Harumi venture through the streets of Ninjago City. Meanwhile, Cole finds out the Palace has been rigged with bombs. Just then, the Sons of Garmadon, led by Ultra Violet and the mysterious Mr. E, attack the Palace to steal the Oni Mask. Hutchins helps Lloyd and Harumi escape with the mask through a secret tunnel, but remains behind. Lloyd and Harumi flee but are attacked by the Sons of Garmadon, who manage to steal the Oni Mask. Returning to the Destiny's Bounty, Lloyd and Harumi reunite with the other Ninja, who reveal them that they are the only ones who managed to escape from the Palace's destruction.

The Ninja allow Harumi to live with them on the Bounty. Lloyd and Jay are told by Mistake of the tale of The Realm of Oni and Dragons and that the Sons of Garmadon plan to use the Oni Masks to resurrect Lord Garmadon. Meanwhile, Cole and Zane manage to get Luke Cunningham to tell them the location of the Sons of Garmadon's hangout. They disguise themselves but Cole's cover is blown and he is captured, while Zane maintains his cover as "Snake Jaguar" and earns Ultra Violet's and Mr. E's, prompting them to bring him to the "Big Man".

Zane, undercover as "Snake Jaguar", is brought into the Sons of Garmadon's hideout in the subway, where he meets Killow, the "Big Man", who is responsible with accepting new members and who challenges Zane to a bike race. Before the race, Zane meets Cole in a cell and learns that the leader of the Sons of Garmadon is named "The Quiet One". Cole escapes with a baby believed to be the "key" to the final Oni Mask. The race starts, but Killow is called by Ultra Violet, who tells him that Snake Jaguar is a Ninja. The Sons of Garmadon attack Zane. Mr. E runs after Zane and as they approach a cliff, they jump off their bikes. Much to Zane's surprise, Mr. E is then revealed to be a Nindroid.

After a battle with Mr. E, Zane is severely injured and left in the desert until the ninja find him. While looking after the baby Cole found, they discover his blanket is a map to the Primeval's Eye, where the Oni Mask might be located. Meanwhile, a device Mr. E placed inside Zane makes its way to the power supply, cutting down the power in the entire ship. P.I.X.A.L. reveals herself to be Samurai X just before her hacked mech attacks. She ejects herself from it, causing it to fall off the ship, but Lloyd and Harumi fall off as well, using the map as a parachute. Meanwhile, Zane wakes up and destroys the spider, but the Bounty crashes into the jungle. Lloyd and Harumi venture into the Primeval's Eye to find the final Oni Mask.

While Lloyd and Harumi venture deep into Primeval's Eye, the other Ninja attempt to fix the Bounty and discover that the baby is Wu, who is recovering from the power of the Reversal Time-Blade. Also, while attempting to reboot in, they discover that the Quiet One is Harumi, but are stopped by the attack of the Sons of Garmadon. Meanwhile, Harumi and Lloyd find a boat and use it to travel along a river, but are attacked by a giant underwater creature, which wrecks the boat. They manage to escape from the monster and fall down the waterfall, where they find the Oni Temple.

Lloyd and Harumi enter the Oni Temple and, after passing by some paintings depicting the Oni and traps, the two eventually find the Oni Mask. However, after Harumi tells Lloyd to pick it up, he realizes that she is The Quiet One. He eventually defeats Harumi in battle, but she grabs the Oni Mask and uses it to defeat Lloyd, before leaving the temple. Meanwhile, the Ninja have been tied up by the Sons of Garmadon, who have taken over the Bounty and use it to arrive at the Oni Temple, but they manage to break free. As the Ninja and the Sons of Garmadon prepare to fight, they are attacked by the underwater monster. The Sons of Garmadon escape aboard the Bounty with all Oni Masks and Lloyd, while the other Ninja are left to deal with the monster.

The Ninja return to Ninjago and arrive at the Police Station to ask for help in stopping the Sons of Garmadon's plan. Meanwhile, the Sons of Garmadon bring Lloyd to the Temple of Resurrection, where the ceremony to resurrect Garmadon will take place. Harumi reveals that she captured Lloyd's mother, Misako, as she needs them both in order to resurrect Garmadon. At nightfall, the Ninja sneak inside the temple, while Harumi opens a portal to the Departed Realm and summons Lord Garmadon. The Ninja manage to use Spinjitzu to close the portal and defeat the Sons of Garmadon. However, the ceremony has been completed, allowing Garmadon to return to Ninjago.
Note: Harumi's look is changed in this episode

Lord Garmadon returns to Ninjago and releases all the imprisoned Sons of Garmadon and Harumi encourages him to "achieve his true potential" by conquering his son. The Ninja find out Garmadon has taken over Kryptarium prison and head there to confront him, but Lloyd, believing he is destined to fight his father alone, locks the other Ninja on the Bounty. Arriving at the prison, Lloyd confronts his father and the two battle, while the Sons of Garmadon broadcast everything in front of all the people of Ninjago. After throwing Lloyd out of the prison, Garmadon unlocks his True Potential and leaves to take over Ninjago City.

The Ninja find Lloyd and manage to save him, at the cost of his elemental powers. Garmadon arrives in Ninjago City and four of the ninja receive a package from Mistaké and leave to fight a stone giant Garmadon built, Colossus. Lloyd runs away with Wu but runs into Harumi. The other ninja make it to the Bounty and arrive in time to rescue Wu but not Lloyd, who is captured by Harumi. Colossus shows up and crushes the Bounty, while Harumi forces Lloyd to watch, but the four Ninja use the package, discovering it to be Traveller's Tea and find themselves in the Realm of Oni and Dragons.

It’s been a week since the newly-styled Emperor Garmadon seized control of Ninjago City. Amidst the chaotic, tyrannical regime, an underground resistance begins to form, led by Nya and Lloyd. Meanwhile, in the First Realm, the other ninjas with a Kid Wu find themselves shipwrecked. Attempting to ensure their survival, they soon discover that they are not alone, in the realm...

The mysterious tribe which captured Kai, Jay, and Zane, named the Dragon Hunters, take them to their leader, the Iron Baron, who seems convinced that the Ninja are Oni and killed the Ultra Dragon. They are escorted to a perilous arena and made to battle a dragon. In a bid to help their friends, Cole and Wu go undercover as Dragon Hunters. In Ninjago, Garmadon destroys Mr. E for failing to capture Lloyd, while the elemental masters, along with Mistaké, reveals to Lloyd that his friends are in Realm of Oni and Dragons and join the Resistance, and seek to inspire Lloyd to regain his power and next is his Golden Power.

Mistaké challenges Lloyd to find his voice, convincing him to broadcast a message to inspire the people. In the First Realm, Kai, Jay, and Zane have been captured and imprisoned in the Dieselnaut and are to be used as bait for that night’s dragon hunt. Cole and Wu, still disguised, join the hunt and learn about the Firstbourne Dragon, the leader mother and queen of all dragons, who wields all the elements. Meeting with the imprisoned Ninja, Cole assures them that they will find a way out of their predicament, "for us, and the dragons".

The Ninja are taken to the Dragon Hunter’s village. Planning to escape, they resolve to build a simulated Firstbourne with Cole and Wu. The resistance, led by a newly motivated Lloyd devise tactics for overthrowing Garmadon. Dareth, feeling excluded due to his lack of elemental power, convinces Mistaké to help him help obtain ‘brown power’.

Harumi leads an attack on the secret headquarters of the resistance. Now sundered, and living in the slums, those remaining discover a secret about Mistaké. The Ninja, now free from the hunters, wake to find a now teenager Wu remembering more about his past. Finding an unlikely ally in Heavy Metal, the Iron Baron's second-in-command, who reveals himself to be a woman named Faith, Wu leads the group to look for the legendary Dragon Armour, which would help them control the Firstbourne Dragon, to save the Realm and return to Ninjago.

Mistaké reveals her true origins to the Resistance and teaches Lloyd that he must transform one final time into the great leader he is destined to become. Meanwhile, Emperor Garmadon embraces Harumi as his daughter of darkness and sends her to capture Lloyd, but she ends up being captured herself. Continuing on their journey with Faith through the desert, the team venture into Oni territory, where they discover that all the Oni are long gone, as well as a map showing the Dragon Armor to be inside Firstbourne's nest.

Faith teaches the Ninja to use vengestone harpoons and Wu to ride a dragon, but when they are found by the Dragon Hunters who capture Faith, Wu and the Ninja are forced to continue their journey alone. Meanwhile, in Ninjago, the Resistance keeps Harumi hostage at their hideout and come up with a plan to have Mystaké disguised as her and Skylor as a prisoner goes to Garmadon's base so that Skylor could borrow his powers and thus be able to control Colossus. However, things don't go as good as planned when Harumi escapes and goes to warn Garmadon.

After trying to rescue Faith, the Ninja and Wu get captured. Faith reveals the Iron Baron's lies to the other Dragon Hunters, while Wu ages up to a young adult and regains all his memories. He makes a deal with Iron Baron who, in exchange for the Dragon Armor, promises to send the Ninja back home. In Ninjago, after being discovered, Mistaké reveals her true Oni nature to Garmadon and confronts him, allowing Skylor to borrow his powers and escape, while she is presumably killed. Skylor struggles with Garmadon over the control of Colossus, but she ends up "poisoned" and Colossus accidentally destroys a building full of people. Harumi goes inside and rescues a family, but the building collapses and she dies. This angers Garmadon, who swears to destroy Lloyd and the entire Ninjago City.

After Harumi's death, Garmadon angrily begins destroying the entire Ninjago City with Colossus, while Lloyd and the others head to a more remote side of the city, waiting for Wu and the other Ninja to return. They run into Ultra Violet, whom Nya has a fight with and gets injured, but they manage to defeat her and continue their path. In the Realm of Oni and Dragons, the Dragon Hunters release the Ninja and Faith after realising that Iron Baron showed his true colors and cares only about himself. Meanwhile, Wu takes Iron Baron to the Firstbourne Dragon's nest, where he dons the Dragon Armor. However, the Firstbourne senses the evil in him and attacks, trapping him in molten rock and leaving him to die. Wu then finds the Armor and becomes the Golden Dragon Master, riding the Firstbourne back to the Ninja and the Dragon Hunters. Faith decides to remain here to lead the Hunters and try making the Realm a better place, while Wu and the Ninja ride each a dragon back home... back to Ninjago!

Wu and the four Ninja are finally back home and reunite with their friends. Nya and Dareth takes Skylor to safety, while Kai, Jay, Zane, and Cole rescue the civilians and fight Colossus, and Lloyd and Wu confront Garmadon. The Elemental Masters and the Ninja's other allies escape from Kryptarium prison and help the Ninja defeat Colossus, while Garmadon defeats Wu and the Firstbourne Dragon, leaving only Lloyd to fight him. After understanding that fighting is what gives Garmadon his powers, Lloyd stops fighting him and just "resists him" instead, by using the Art of the Silent Fist, which causes Garmadon to slowly lose all his powers and Lloyd to restore his and next is his Golden Power. However, although Garmadon is finally defeated, he warns Lloyd that his powers were the only thing strong enough to prevent some dark forces from attacking Ninjago, and now that they're gone, "they" will come and destroy everything. In the aftermath of the battle, Colossus gets destroyed and all the Sons of Garmadon, including Garmadon, are arrested; Skylor gets back to normal health who wakes up tended by Kai and after her health is restored; and the people of Ninjago celebrate the Ninja and their allies. Some time later, Lloyd meets with Wu, now back to his normal age, who tells him that the Firstbourne and the other dragons have to return to The First Realm, and will return only when they'll be needed again. Lloyd then tells Wu about his father's warnings and, after learning that all the Oni are gone from The First Realm, concludes that "they" means the Oni, and that "they" are coming.

• The Fold Band appear as Lego band singing The Weekend Whip.

Lloyd visits Garmadon at Kryptarium prison, who tells him that "The Darkness", which is to destroy all the realms, is soon going to arrive in Ninjago, while Cole,Zane and P.I.X.A.L go to the harbour to receive an award.They are surprised to find out that "The Bounty" has been remade.Faith, who has been severely injured arrives at the monastery and warns Wu and the rest of the ninja about the darkness.The ninja decide to free Garmadon from Kryptarium Prison.

Having freed Lord Garmadon from Kryptarium Prison, the ninja are beset by doubts, particularly Lloyd. After a provoked battle results in the return of Garmadon's powers, Lloyd and Garmadon enter the cloud of darkness in an effort to stop the invasion. After encountering a pair of Oni, the two reach the Realm Crystal, but are too late, as the Oni's leader, Omega, is released upon Ninjago.

While Lloyd and Garmadon try to escape the Oni, P.I.X.A.L. prepares to enter the darkness to save them. Meanwhile, the Ninja tend to a distress call, but Cole ends up falling into the darkness. Garmadon and Lloyd obtain the Armour of the Golden Master, and Nya tells Kai he must melt the armor back into the Golden Weapons.

The Ninja return to the Monastery of Spinjitzu, in the last stand between them and the Oni. Kai recreates the Golden Weapons to help the team fight the Oni. In the midst of the battle, Cole, who has survived the darkness, returns to the monastery as well. The Ninja, Wu and Garmadon eventually use the Tornado of Creation to defeat the Oni. Lloyd sees his grandfather the First Spinjitzu Master in a vision, and after his recovery, the Ninja and their allies celebrate their victory by putting their hand together on the Monastery’s wall.

Having grown complacent in the wake of their victory over the Oni, the ninja are enjoying life, playing video-games, sleeping in, and soaking in a hot tub (fashioned from one of the monastery's enormous bells). Unfortunately, this behavior quickly grows tiresome and the ninja are confronted by Master Wu, who accuses them of not taking their duties seriously. The ninja deny this, and Wu decides to put them to the test with a series of booby-traps and pranks intended to test their reflexes and skills. Among the more dangerous challenges, the ninja must catch a dangerous breed of chicken that grows wild in the hills surrounding the monastery. Put to shame by the chicken, the ninja ultimately realize: Wu is right. They have gone soft. They decide to take on a new quest to get back in ninja-shape.

Realizing they have gone soft, the Ninja search for a quest to reignite their Spinjitzu training and try to cooperate with the police in fighting crime; unfortunately, Ninjago City is enjoying a period of rare tranquility. Having given up hope, the Ninja learn of Clutch Powers' recent discovery and decide to go exploring with him.

• Note: This is the 100th episode of the series overall.

The Ninja set off for their quest in the Desert of Doom, but on the way are attacked by an ancient giant scarab beetle. Eventually, they manage to escape it, but are stranded in the middle of the desert.

To repair the Land-Bounty, the Ninja must retrieve a critical engine component that has been swallowed by the giant beetle. Zane decides to get swallowed himself, and once he has found the component, the Ninja pull him back up with a rope. Then, they fix the Land-Bounty and escape the beetle.

The Ninja persuade Clutch Powers to enter the Ancient Pyramid with them and they survive many booby traps along the way. However, they accidentally release Aspheera from her tomb, and she brings the Pyro Vipers to life and entombs the Ninja. She then leads her forces towards Ninjago City, looking for a "treacherous deceiver".

This episode is a crossover with "Lego: The Adventures of Clutch Powers"

Nelson teams up with Antonia on his first day as a paperboy. While trying to deliver the papers around a rampaged by the Pyro Vipers Ninjago City, they get a message that the Ninja is in trouble. Nelson persuades Antonia to help him warn Master Wu.

• Note: This is the first episode of the show to not feature any of the Ninja in any way.

The Ninja are trapped in the pyramid and try to escape, but encounter encroaching lava and traps along the way. They soon understand that their lack of coordination as a team may prove deadly and work together to escape the pyramid. However, when things get very difficult, the Ninja are saved by P.I.X.A.L., who tells them of the Pyro Vipers' attack in Ninjago City.

While the Pyro Vipers attack Ninjago City, reporters newscast the event which has become known as Snaketastrophy. Meanwhile, Aspheera learns of the Scroll of Forbidden Spinjitzu and sets off for the Ninjago Museum of History, while the Ninja reach the city and battle the Pyro Vipers.

The Ninja rush to the museum to recover the scroll before it falls into the hands of Aspheera, but they arrive at the same time and battle for the scroll. Its power surpasses Lloyd, but Aspheera acquires the scroll and traps the Ninja. A fan named Jake prompts Kai, now powerless, to never give up and save his friends.

While Aspheera pursues revenge on the "Treacherous Deceiver" who betrayed her, the Ninja go underground seeking the Serpentine. There, they make a discovery leading them to believe Lord Garmadon is the "Treacherous Deceiver", but Wu corrects them revealing himself to be the one.

Wu and Lord Garmadon decide to visit the forbidden Serpentine Valley, breaking a peace, and are captured by the Serpentine, but are released by Aspheera with the promise of teaching her the secrets of Spinjitzu. Wu keeps his promise and teaches her, but she uses the power to take over her Tribe. The two brothers use the Scrolls of Forbidden Spinjitzu to overthrow Aspheera, who is entombed for her actions.

Having learned Master Wu is the "Treacherous Deceiver", the Ninja find themselves under siege at the Monastery, trying to protect Wu from Aspheera. The Pyro Vipers manage to enter the Monastery, but the Ninja, P.I.X.A.L., and Wu have hidden in the underground base.

The other Ninja learn of the second Scroll of Forbidden Spinjitzu's location from Clutch Powers and break into the Explorer's Club to obtain it, running afoul of the club's manager and irritate club members. In the end, they obtain the scroll but wreak havoc in the club.

Aspheera breaks into the underground base and confronts Wu, but the Ninja arrive with the second scroll and battle her. Zane eventually defeats her, but she manages to strike him with her scroll. Although the Ninja believe Zane's dead, Wu discovers from Aspheera, who has been imprisoned, that Zane is banished to a distant and remote realm called the Never-Realm.

Having learned Zane is not dead from Aspheera,but has been banished to the Never Realm, Master Wu prepares to go after him, but the Ninja want to come along as well. When he denies, they take matters into their own hands and defy him. However, Wu uses the Scroll of Forbidden Spinjitzu to stop the Ninja from leaving. However, the Ninja defeat him and go themselves to the Never-Realm, before Wu warns them that there is no way back - the reason it is called the Never Realm.

The Ninja arrive in the Never-Realm and try to find shelter while wolves attack them, but villagers save them and take them to their village. One of them tells the Ninja about the Ice Emperor and that Zane is in the Emperor's palace. Meanwhile, Vex, the advisor, tells the Emperor that strangers have arrived and prepares to attack the ninja.

The ninja and the villagers prepare to fight the Blizzard Samurai. While fighting Lloyd and Cole realize that some of them are made of Ice and some were corrupted people. Grimfax extinguishes the Hearth Fire. However, after they defeat the Blizzard Samurai, Kai tries to make fire, using his elemental powers by believing in himself and succeeds in restoring the Hearth Fire, gaining the title "Fire maker".

The Ninja help the villagers to build weapons in case the Blizzard Samurai return again. Lloyd begins his journey to the Ice castle with the Titan mech tracker that Nya gives him to find it. In his road, he is attacked by wolves, but one of them forces them to retreat. Later, Lloyd gets ambushed by the Blizzard Samurai, but he successfully evades them. He arrives at the Land Bounty, finding it damaged by the freeze.The wolf that forced the others away strangely follows and stays with him. The tracker locates the mech, giving Lloyd hope to find Zane.

When Ultra Violet learns that the Ninja have gone missing, she and The Mechanic plan to escape. In the escape route, they begin to discuss about who is the worst ninja. They are soon interrupted by Fugi-Dove, an infamous criminal. They continue talking along the route. Once they have escaped, P.I.X.A.L catches them and they are thrown back into their cells.

Vex, bitter and seeking revenge from his enemies, meets Zane, who has arrived in the Never-Realm and has lost all of his memories. He tricks Zane into believing he is the Ice Emperor, ruler of the realm with Vex being his trusty advisor. Prompted by Vex, Zane uses the Scroll of Forbidden Spinjitzu to brutally punish Vex's enemies and takes over the Never-Realm, placing it under an eternal winter.

Having discovered the terrible truth of Zane's fate, Lloyd tries to help him remember his true identity, but Vex persuades him into believing Lloyd is a liar. Lloyd is locked up in the dungeons, where he meets Kataru, Akita's brother who has been kept captive for a long time. When all hope seems lost, Grimfax frees them, having believed Lloyd's story and offering to team up with them.

Nya, Jay, Cole, and Kai face off against Boreal, while Lloyd confronts the Ice Emperor himself. Meanwhile, Kataru and Grimfax try to stop the ice army from getting to Lloyd. As Akita wanted revenge, she went to find the ice emperor and tried to kill him.

Lloyd helps Zane regain his memories. Akita is reunited with Kataru, and the ninja are all reunited. They return to Ninjago city.

The Mechanic and his henchmen infiltrate an old electronics warehouse in search of a mysterious motherboard. The ninja learn of the heist and arrive to thwart the attack. But they're completely in the dark as to what the Mechanic wants with it, so they head to the Mechanic's headquarters looking for clues. There, the ninja find the legendary, unreleased arcade game called Prime Empire. Realizing the game is missing a motherboard, Jay inserts the motherboard and the game boots up. While Jay plays the game, the other ninja make their way into the Mechanic's private office where they intercept a phone call intended for the Mechanic. It's a mysterious new villain called Unagami, for whom the Mechanic seems to be working. Meanwhile, Jay accidentally triggers an energy pulse that converts all of the arcade games in Ninjago City into Prime Empire arcade games.

When the ninja discover that Jay has disappeared into the arcade game, they interrogate the Mechanic, hoping to learn who the mysterious Unagami is and how they can get Jay back. But the Mechanic refuses to speak. While they are at the police station, they learn from the Commissioner that something strange has affected all the arcade games in Ninjago City, turning them into Prime Empire ones. Fearing that whoever plays them will disappear like Jay, the ninja urge the Commissioner to pull the cabinets out of the arcade games. As the police rush to comply, the ninja head off to Dyer Island, an island outside Ninjago City, where they hope to find Milton Dyer, the creator of Prime Empire. On Dyer Island, the ninja instead meet Bob the Intern, who used to work for Dyer. Bob explains that Prime Empire was a project that was shut down by the company Dyer worked for because it was too dangerous, and that Milton Dyer vowed to get revenge on the gaming industry afterward. The ninja then conclude that Dyer must be Unagami.

More and more people are disappearing in Ninjago City, while the ninja scramble to unlock the secrets of the Prime Empire arcade game. They decide to take the game to Cyrus Borg, hoping he can help them decode the programming and release all the players who have been taken (including Jay). Meanwhile, the Mechanic and his henchmen are resting in Kryptarium Prison when the jail's security systems begin acting up. Unagami hacks the security system and releases the prisoners, ordering them to get the Prime Empire arcade game back from the ninja. Mechanic, Ultra Violet, and Captain Soto escape, rush to Borg Tower and begin their assault, fighting their way past the building's security systems to reach the 100th floor. Borg tells the ninja that there is only one way to release the trapped players - by stopping Unagami. Cole plays the arcade game and tries to reach Level Thirteen. He does successfully, and the ninja enter the game.

The ninja materialize inside Prime Empire and go immediately on the run when they discover a squadron of Red Visors waiting for them! They are pursued through a marketplace by the Red Visors and are cornered. Luckily, a group of rebels called the League of Jays arrives to save them. The ninja are initially confused but soon discover that during Jay's time in the game, he amassed a following of fans who have devoted themselves to his "teachings". The League of Jays helps the ninja escape from the Red Visors and leads them to Scott, the race car mechanic. As they cross the marketplace, the ninja make several discoveries. They learn that their ninja skills don't work in this digital world. Skills can only be bought or earned by playing the game. They then learn they have four lives, and when they lose those lives, they will be converted into energy cubes and whisked away by flying drones.

Okino is a serious, duty-bound Samurai warrior who is unaware that Prime Empire is a game, since he is part of it. His job is to lead players through the three dangers of Terra Karana - the Forest of Discontent, the Cliffs of Hysteria and the Maze of the Red Dragon where the first Key-tana is located. Unfortunately, the game is rigged to be nearly impossible and Okino quickly fails his masters, who are dematerialized into cubes of energy. As more and more masters are "cubed", Okino begins to lose faith in his abilities. One day, Okino meets another Samurai like himself who is more successful in keeping her master alive. Okino internalizes this as a fault of his own so he trains and pushes himself as never before. Despite all his efforts, he loses more masters. Okino prepares to abandon his responsibilities when a final group of travellers arrive, seeking his help. It is the ninja.

The Samurai guide, Okino, leads the ninja into the first of Terra Karana's deadly challenges: The Forest of Discontent, made up of deep, dark woods, filled with booby-traps. As the ninja fight their way through it, they begin losing lives, but with Okino's help, they survive and reach the middle of the forest. There, they are ambushed by the Whack Rats but the ninja are able to fight them off. Lloyd ties up the leader, a rat named Richie. In order to procure his release, Richie tells Lloyd that he knows about a "glitch" in the game, which will allow the ninja to bypass the rest of the booby-traps and reach the other side of the Forest. Okino soon realizes Prime Empire is not a real place, merely a simulation and he is part of it. Lloyd releases Ritchie, who guides the ninja to the glitch and into an ambush by Red Visors. Okino comes to their rescue and helps the ninja escape.

The ninja arrive at the Cliffs of Hysteria where they meet Shifty, a merchant who runs a table at the base of the cliffs. Shifty sells the ninja some grappling hooks and rope. Unfortunately, the ninja don't have enough money to buy the "Rope of Supreme Durability" and opt instead for the "Rope of Questionable Integrity". Even worse, as they are buying the rope, they are spotted by one of Unagami's aerial drones. A squadron of Red Visors quickly arrives and pursues the ninja up the cliffs. The ninja, who only have ropes, must climb while the Red Visors have jet-boots and are able to catch up quickly. During the ensuing battle, Cole is nearly lost, but is saved at the last moment by Kai, who makes a daring leap onto the back of the flying drone and uses the drone to blast the Red Visors. They learn that Unagami is using the energy cubes to build a portal into Ninjago City.

As the ninja and Okino approach the Maze of the Red Dragon, Unagami uses his control over Prime Empire to briefly "pause" all the players except Okino. He appears before Okino, urging Okino to betray the ninja and not help them against the fearsome Red Dragon that awaits the ninja at the heart of the maze. If Okino betrays them, Unagami promises to bring him with into the real world. He then disappears and restores the ninja back to normal. The ninja arrive at the heart of the maze and find themselves outmatched by the Red Dragon, and appeal to Okino for help. Okino struggles with his decision but cannot in good conscience betray the ninja. He defies Unagami, his creator, and helps the ninja defeat the Red Dragon by revealing its weakness: a scale on its chest. The ninja defeat the dragon and Jay delivers the final blow. The Red Dragon changes colour and vanishes into an amulet. The ninja then continue their quest.

Having obtained the first Key-tana, the ninja enter the second of Prime Empire's game zones, Terra Technica, where they learn that the second Key-tana can only be won by winning a dangerous race called the Speedway Five-Billion. The ninja realize that they don't have enough game credits to enter the race but earn credits when Jay and Nya win a dance competition.

The ninja appeal to Scott for help in obtaining 5 race cars. Scott shows them his junkyard where he has 5 vehicles that may be repairable in time. Lloyd heads off to the racetrack and watches a live race, hoping to learn as much as he can about the brutal Speedway Five-Billion. One driver in particular impresses Lloyd - a race car driver known as 'Racer Seven'. Lloyd recruits her to help them win the race.

Red Visors discover the location of Scott's garage and Scott sacrifices himself to buy the ninja a chance to escape and they race off. The ninja enter the Speedway Five-Billion in the nick of time, just as the race is starting, and find themselves quickly overwhelmed. Cole and Kai bravely sacrifice themselves to buy their teammates a chance to win. With the help of Racer Seven, however, they successfully win the second Key-tana.

Devastated by the loss of Cole and Kai, the surviving ninja push on into Prime Empire's third and final game zone - Terra Domina. They ultimately arrive at the upper-most level where Unagami's voice tells them that one of the ninja will now face the form of his own most dreaded challenger. Lloyd is selected and finds himself facing an avatar of Harumi. Lloyd manages to defeat Harumi and wins the third and final Key-tana for the team. Lloyd, however, also loses his final life in the process.

Zane and P.I.X.A.L. visits an old childhood contact of Milton Dyer's who tells them that Dyer used to frequent an old video arcade hall called Buddy's Pizza. They head there to search for Dyer, but run into the Mechanic, who kidnaps Zane. P.I.X.A.L. ultimately finds Milton Dyer, who tells her that Unagami "is the game". He had not realized how dangerous it was, and tried to shut it down.

The Mechanic's henchmen capture Master Wu and bring him to the Mechanic's warehouse. The Mechanic uses him as leverage to coerce Zane into revealing the location of the motherboard which he requires to open the Manifestation Gate, through which Unagami is to enter the real world. Wu manages to activate a GPS location tracker, which reveals his location to P.I.X.A.L. However, she and Dyer arrive too late. Zane is hooked up to the Manifestation Gate as a type of processor, causing him to pass out as a result of the energy surge caused by the gate.

Jay must stand alone against Unagami in the end-game, after Nya loses all her lives due to being stabbed through the back by an NPC named Sushimi, yet Unagami has a bigger battle in facing the truth about his own identity. Jay discovers that Unagami is actually the AI of the game and not Milton Dyer. Unagami uses the energy cube from Nya to complete the Manifestation Gate, and travels through it. Jay follows after him.

Unagami breaks into the real world and terrorizes Ninjago City along with his army. Jay releases Zane from the gate. Zane, P.I.X.A.L., and Master Wu fight off Unagami's forces forces while Jay chases Unagami himself. Jay leads Unagami to the top of Borg Tower, where he is met by the others along with Milton Dyer himself. Dyer explains to Unagami why he shut him down and that chaos and destruction was not what he was made for. Eventually, Unagami understands. He takes the form of a small child and agrees to set everyone trapped inside Prime Empire free, including the other ninja, the trapped players, Scott, and the NPCs. Jay, Zane, P.I.X.A.L., and Wu reunite with the other ninja while Unagami and Milton Dyer live happily together.

The ninja are invited to the birthday of Princess Vania of the fabled Kingdom of Shintaro and set sail for Shintaro but are attacked by a pack of Dire Bats, vicious aerial predators who roam the mountains around Shintaro. They are rescued by a regiment of the Winged Guards of Shintaro, led by the brave Hailmar.

The ninja are welcomed to Shintaro by King Vangelis and Princess Vania. Cole is accosted by a Geckle named Gleck who is wearing a necklace that belonged to his mother. Princess Vania leads Cole to a mountain tunnel and they stumble upon an underground mining operation where Geckles and Munce are being forced to dig by an army of Skeleton Warriors, controlled by the vicious Skull Sorcerer.

Cole is a prisoner of the Skull Sorcerer while Princess Vania races back to the surface where she tells the ninja and her father what she saw below. The ninja quickly gather their things and race to Cole's rescue. Deep underground, Cole toils in darkness alongside the Geckles and Munce, whom he discovers are bitter rivals over a past grievance that each side blames upon the other.

The ninja learn that the Geckles' and Munce's mutual hatred stems from the fact that each group thinks the other stole a pair of swords called the Blades of Deliverance, which were given to them by a hero who came to their mountain many years earlier. The hero, whom the Geckles call "Gilly," saved them from a dragon named Grief-Bringer and gave them the swords as a farewell gift.

Having become separated from the others, Nya, Jay, and Lloyd are led back to the Munce "Home-Cave" by a Munce named Murt. There, they are introduced to the Munce Queen, Murtessa, who immediately falls for Jay, whom she considers a powerful warrior. Realizing that Nya and Jay are engaged, the queen turns on Nya and challenges her to combat to determine which of them shall wed Jay.

Kai and Zane stumble into a party of Geckles who think they may be working for the Skull Sorcerer. They are arrested and brought back to the Geckle "Strong-Cave," where they meet the Geckle leader, Chancellor Gulch. Gulch decides to put the matter to a "Trial-By-Mino." Kai and Zane are cast into a pit with a raging Mino to determine their innocence or guilt.

Cole runs first into a nest of Dire-Bats, and then into a cave tunnel filled with giant spiders, but Princess Vania and her pet dragon, Chompy, arrive just in time to free Cole and they escape back to the surface where they tell King Vangelis about the evil Skull Sorcerer. In a shocking twist, however, Vangelis reveals that he IS the Skull Sorcerer. After the Skull Sorcerer sends Cole and Master Wu to the bowels of the mountain, Vania follows them but not before Vangelis disowns her as his daughter.

Princess Vania attempts to catch the falling Master Wu and Cole, but their combined weight tears her wings loose. All 3 friends find themselves plunging into the mountain. As they fall, they encounter various bizarre threats and creatures before they are swept over a waterfall and tumble through a sinkhole to wash up on the shores of a cavern called Rock-Bottom, where he meets a group of adventurers down here.

Cole awakens from a dream to find himself surrounded by the Lowly, Master Wu, and Princess Vania. The Lowly reveal they were adventurers who, at the request of King Vangelis, went searching for the Skull of Hazza D'ur. They found the skull and delivered it to the King, who - instead of destroying it, as he had promised - betrayed them and cast them into the mountain, taking the skull for himself.

• Note: This episode partly uses 2D animated style.

Cole leads the Lowly, Princess Vania, and Wu in a series of fruitless efforts to find a way out of Rock-Bottom. Wu tells Cole about a legendary Temple of Earth Elementals known as the Heart of the Mountain. Surmising that the Temple is actually real, Wu guesses that it might be hidden in Shintaro Mountain and urges Cole to try and tap into his elemental powers to find a way out.

Nya uses her elemental powers to coerce the Munce into agreeing to a truce meeting with the Geckles. At the same time, in the Geckle camp, Kai and Zane are forced to resort to trickery in order to manipulate the Geckles to attend the truce meeting. The Skull Sorcerer learns of the meeting and uses the skull of Hazza D'Ur to resurrect the fearsome dragon Grief-Bringer!

Cole, Princess Vania, Master Wu, and the Lowly arrive at an ancient abandoned temple. Wu realizes it is The Heart Of the Mountain. The group discover an old abandoned Stone Mech and a mural of Cole's mother, Lilly. In the mural, she is depicted fighting the dragon, Grief-Bringer, using the Spinjitzu Burst. Wu tells Cole about the Burst - a powerful form of Spinjitzu which his mother studied.

The Skull Sorcerer hunts down the ninja who flee to the Geckle "Strong-Cave". The Skull Sorcerer promises to let the Munce and Geckles live if they turn over the ninja. Nya stumbles on a possible way out of the cave and the Munce and Geckles work together to clear a rubble-strewn tunnel. The Munce and Geckles begin to work past their differences. But then Grief-Bringer forces his way into the cave. Left with no other choice, the ninja surrender themselves up but not before the Skull Sorcerer imprisonments all of the Geckles and the Munce.

Cole discovers that the stone-mech is powered by Elemental Earth energy and uses his powers to activate the mech. He straps the mech to the mine-carts and uses it, like a crude rocket, to blast the mine-carts back up the track to the top of the mountain. Along the way, however, the Magma Monster arrives and a desperate battle between Cole and the creature ensues. During the aftermath, Hailmar and the Winged Guards of Shintaro arrive and are preparing to arrest Cole and Master Wu on King Vangelis’s orders but not before Vania challenges Hailmar so he’ll listen to her.

Cole and the Upply arrive at the Skull Sorcerer's Keep and find the ninja locked into cages. The Geckles and Munce have been put back to work in the chain-gang, mining Vengestone. While Jay is formulating a plan, he sees the Skull Sorcerer draw the two fabled Blades of Deliverance. Hoping to retrieve the blades, Cole sneaks into the Skull Keep while Wu and the Upply set about freeing the ninja.

As Cole and the Skull Sorcerer face off, the Geckles and Munce storm the Keep. Plundar frees the ninja from their cages and the ninja join the battle. Vania arrives leading the winged Shintaro Guards. The Skull Sorcerer destroys the supposedly "fabled" magical Blades, revealed to be nothing more than ordinary swords. Grief-Bringer awakens and joins the fight, and all looks lost. But at the last minute, Cole manages to uses the Spinjitzu Burst and defeats the Skull Sorcerer. After his defeat Vania has now proclaimed herself the Queen of Shintaro while the ninja leave the Ivory City, seeking a new adventure on their path. Wu states that he would rather continue and go wherever the wind takes them.
