Main Characters
Ben Tennyson: The Hero with the Omnitrix
Benjamin Kirby Tennyson, also known as Ben 10, is the main hero of the Ben 10 shows. When he was 10 years old, Ben found a special watch called the Omnitrix during his summer vacation. This amazing device attached to his wrist and let him change into many different aliens! He uses these alien powers to fight bad guys and protect people. But he also has to watch out for the alien warlord Vilgax, who really wants the Omnitrix for himself.
At first, Ben was a bit self-centered and only liked being a hero for the excitement. People sometimes wondered if he was truly ready to be a hero. But as the series went on, Ben grew up a lot. He became a strong leader, especially when his Grandpa Max disappeared. Even though he could be a bit silly sometimes, Ben always wanted to help and protect his family and friends. He's also super clever when he needs to be, like when the Omnitrix gives him the wrong alien, and he still finds a way to win!
Later, Ben stopped using the Omnitrix for a while. But when Grandpa Max went missing, Ben put the watch back on to find him. After saving the world from the Highbreed, Ben became a famous hero. He even got a new version of the Omnitrix called the Ultimatrix, which could turn his aliens into even more powerful "Ultimate" forms!
In Ben 10: Omniverse, Ben gets a new partner, Rook Blonko, because Gwen and Kevin go off to college. Ben also learns about Undertown, a secret city where aliens live right under his hometown! By the end of the series, Ben decides to travel the galaxy with his friends.

In the first series, Gwen and Ben often argued, but they always had each other's backs. Gwen is super smart and a skilled martial artist. She has black belts in Karate and Taekwondo, and she's also trained in Jujitsu. She's a fantastic student and even goes to a top college later on!
Gwen's most special power is her amazing magic. She can use different magic items and spells, and she can create pink or magenta energy blasts and shapes, like weapons. She even became a superhero called "Lucky Girl" twice! Later, Gwen finds out her powers aren't just magic; they come from her alien grandmother, who was an Anodite. Anodites can control mana, which is like the energy of magic and life. When Gwen gets really angry or stressed, she can even turn into an Anodite energy form!

Ben and Gwen first thought he was just a regular plumber, but they later found out he was a "Magister" (a leader) in a secret space police group called the Plumbers!
Max drives a cool RV called the "Rust Bucket," which is secretly packed with Plumber weapons and tech. He was supposed to receive the Omnitrix, but Ben found it instead. Max also had a romantic relationship with an alien called Verdona, who was an Anodite, just like Gwen's powers!

Kevin had a tough childhood and ran away from home. He met Ben and tried to use the Omnitrix's power for himself, which accidentally turned him into a mix of Ben's aliens. After spending time in the Null Void, he learned to control his powers and became normal again.
Kevin might not have gone to school much, but he knows a lot about aliens and their tech. He has a cool muscle car that's tricked out with Plumber and alien technology. Even though he's a good guy now, Kevin can still be a bit selfish sometimes. He's a loyal friend and a strong ally to Ben and Gwen.
In Ultimate Alien, Kevin accidentally absorbs too much energy from the Ultimatrix, which makes him lose his mind and turn into a monster again. Ben and Gwen have to find a way to help him.

Even though he's very good, he doesn't have much real-world experience at first.
