Sonic the Hedgehog is a video game character. He is a 15-16-year old blue hedgehog who can run at the speed of sound. By curling into a ball and spinning quickly, he can do a helpful "Spin Attack" which he uses to defeat the bad guys and save the day. Because he is very fast, he hates waiting, and he can be a bit rude, but he does care about his friends and really hates evil. He has been in many games made by the company Sega, but also in television series, books and comics (published in America by Archie Comics). He has many friends, including Miles "Tails" Prower, a two-tailed fox that can fly by spinning his tails very quickly or Knuckles the Echidna (who is strong, and has been in Sonic games since Sonic the Hedgehog 3). With them, he fights against Doctor Eggman, an evil scientist who tries to take over the world. Doctor Eggman was also called Doctor Robotnik in America for some time until it was changed to Eggman to match what he was called in Japan.

Sonic's appearances

In games

Sonic is the mascot of Sega, which created it in the early 1990s. At first, Sega wanted Doctor Eggman to be their mascot, and a good guy. But, the people in Sega liked the new idea of making a blue hedgehog as the mascot. Doctor Eggman settled as the bad guy instead.

Here is a list of some games Sonic is in:

In cartoons

He appeared in his own made-for-video movie in 1999. In most of the cartoons from the 1990s his voice was provided by Jaleel White (who was best known at the time for his role as Steve Urkel on the television show "Family Matters") and in later cartoons his voice was provided by Jason Griffith. Sonic also stars in his latest cartoon from Japan. It is called Sonic X, although Sonic X has ended.

Here is a list of cartoons Sonic is in:

In comic books

Archie Comics in America has been making comics with Sonic as the main character. He is also shown with famous characters like Knuckles and Tails, but with also a few new ones. Some of the characters are not in any Sonic games, but some are in a very old cartoon, Sonic the Hedgehog SatAM, made by DiC in 1993.

Other Sonic characters


  • Miles "Tails" Prower: Tails is a young fox who is 8 years old. He has two tails that he can spin like a propeller, allowing him to fly. He has been a friend to Sonic for a long time. He also sees him as a mentor, someone who trains him and treats him as a brother. He is also very skilled with machinery (mainly aircraft.) He was first shown in the video game Sonic the Hedgehog 2. He can also turn Super using the Super Emerald,which Sonic and Knuckles uses to turn Hyper.
    • Personality: Tails is a very friendly and humble fox. Though he lacks confidence, he is always quite capable around Sonic and often helps him out. For a long time Tails seemed happy with just being a sidekick, but in Sonic Adventure he wanted to be more independent. Tails has a few weaknesses; he lacks confidence, is very afraid of lightning and ghosts, and also he has a tendency to talk too much, which causes him to accidentally blab out secrets or plans lots of times.
  • Knuckles the Echidna: Knuckles is a 15-16 year old red echidna. He may be the strongest of all of the characters and has two sharp claws on each fist he uses to fight with bad guys. Most of the time, he takes care of a very special gemstone called the Master Emerald on Angel Island, a floating island in the sky. He was first shown in the video game Sonic the Hedgehog 3. He can also turn Super using the Emerald,and Hyper using the Super Emerald,which Sonic uses to turn Hyper.
    • Personality: In the games, Knuckles is independent, headstrong, devoted to his duty and is very trusting (this leads to him being tricked by Eggman a lot). He is very serious and usually likes to be by himself, but can be relied upon to help out whenever the planet is in danger. Knuckles is extremely stubborn and is often described as a loner. Because of his flaws, he and Sonic do not always get along, but are still allies.
  • Amy Rose: Amy is a 12-13 year old pink hedgehog. She is in love with Sonic and she wants to marry him, but so far, Sonic has not accepted this offer. She has a large Piko-Piko hammer for fighting with bad guys. She was first shown in the Sonic CD game.
    • Personality: Amy was once presented as being kind and sweet (and slightly naive.) In more recent games she has become more violent and aggressive. However, she is extremely protective of her friends, and if a bad guy tries to hurt them, she will use all her skill to defeat the bad guy. Despite her violent tendencies, Amy has a very good heart, she never gives up, and she is the most optimistic and cheery character of the franchise. She really cares about her friends, and helps them reach their goals.
  • Cream the Rabbit: Cream is a 6 year old rabbit who can fly with her ears. She also has a friend, a baby chao named Cheese. She was first shown in Sonic Advance 2 for Game Boy Advance. She is a very close friend to Amy.
    • Personality: Cream is polite, follows manners, and does what she is told. She is very friendly. She is brave as well, usually not afraid to go out on an adventure. However, she is a bit naive. Cream spends most of her time outdoors. There, she likes to play with her friends, or collect flowers. She loves adventures and exploring. Indoors, she likes watching TV. Her favorite food is ice cream. She does not like violence. However, she will fight to protect the people she cares about.
  • Shadow the Hedgehog: Shadow is a 50 year old black and red hedgehog with super speed like Sonic's. He is actually immortal due to scientific experimentation, but he has the appearance of a 15 year old hedgehog. He is also known as Project Shadow and "The Ultimate Life Form". He is often mistaken for Sonic, although they have some differences between them. Shadow has red and black quills and they are more spiky then Sonic's (resembling Sonic's super form). Shadow was created by Dr Gerald Robotnik (Dr Eggman's grandfather), for the intent of creating peace on earth, on the Space Colony ARK. His creation, however, was enabled by the blood of Black Doom, the leader of an alien race called the Black Arms. His goals were different than Dr Gerald, as he wanted Shadow to collect the Chaos Emeralds for him so the Black Arms could rule Earth. After his creation, Shadow spent some time with Maria (Gerald's granddaughter and Shadow's first friend) who taught him about humanity, true friendship and how to be kind to others. But the G.U.N. (Guardian Units of Nations) thought he would be a threat to humanity. As a result, they eliminated everything related to the project, including the staff and Maria, who was in the process of saving Shadow. He was sent from the ARK in an escape capsule, but was captured by G.U.N. and was kept frozen (like Fry from Futurama) at their base at Prison Island. The death of Maria made Dr Gerald go mad, altering Shadow's memory while he was still frozen to manipulate him into trying to destroy Earth. With help from Sonic and his friends, he was able to regain his memory and his purpose to save the earth, and stopped Dr Gerald's plan to crash the ARK into the planet. This lead to Shadow falling from space and getting amnesia, only remembering Maria's death. He went to find his memory, which lead to him defeating Black Doom and the Black Arms. He has made a commitment to live his life without the burden of his past. He took an offer from the present Commander of G.U.N. to work with them as an agent, but he still works on his own terms. Shadow has unique abilities to use the Chaos Emeralds in ways Sonic and friends have never shown to be able to. One of these is Chaos Control, the ability to warp and manipulate Time and Space with a Chaos Emerald's power. Shadow's first appearance was in 'Sonic Adventure 2'.
    • Personality: Shadow is of Sonic's most pronounced rivals, but at the same time, is one of his friends. Originally an enemy, he is more like an antihero nowadays. Shadow's personality is very different from Sonic's, being very serious and somewhat cocky. He originally had an obsession for finding out the truth about his past, but now since he has found it, he is willing to live a normal normal a life can be for Shadow, that is.He can also turn Super using the Emerald.
  • Rouge the Bat: Rouge is a 19 year old majestic spy. She works for the Government Agency called G.U.N. Her hobbies include treasure-hunting and collect rare gems, including the Chaos Emeralds. Her powers include flying with her wings and doing powerful kicks with her feet. She is often with Shadow (being his only true "friend") and likes to "tease" Knuckles (Sonic X makes this out to me more of a romantic relationship than the games do.) Rouge's first appearance was in 'Sonic Adventure 2'
    • Personality: Rouge was originally self centered, but over time, she has learned to show concern for others (especially her friends Shadow and E-123 Omega, one of Eggman's robots who rebelled). She is not above using her looks to get what she wants.
  • Cosmo: Cosmo is a female child of a plant-like alien species whose homeworld was destroyed by the villainous Metarex. She is an friend of Sonic the Hedgehog and his friends, and many see that her primary purpose in the series is that of a love interest for Tails. This is because the two characters are of the same age for one another. She is only in the Sonic X Cartoon.


  • Doctor Eggman: Doctor Eggman is a smart scientist. He likes to make an army of robots to take over the world, but Sonic and his friends always keep making him fail. He was first shown in Sonic the Hedgehog. In early U.S. releases of the games, he was called Doctor Robotnik. He is called Doctor Eggman because his body is shaped like an egg.
  • Eggman NEGA: Eggman Nega is one of Dr Eggman's relatives from the future. (He first appeared in Sonic Rush) There is some confusion as to whether he is from a different Dimension (as stated in the Sonic Rush series) or from the future (stated in Sonic Rivals)


  • Super Sonic is actually Sonic himself. As Super Sonic, Sonic is faster and stronger, and he is gold in color. He becomes Super Sonic only if he finds all seven Chaos Emeralds and, in the old games, gets a certain number of gold rings. He was first shown in Sonic the Hedgehog 2. Many other characters can become a Super character. For example, Knuckles can become Super Knuckles.
  • Hyper Sonic: Hyper is like Super Sonic, but he is even more powerful. His color is always changing. Hyper Sonic was in Sonic the Hedgehog 3 and Knuckles and was not in any other Sonic the Hedgehog games. Super Sonic becomes Hyper Sonic if he finds the 7 Super Emeralds and fifty golden rings and then double jumps.


  • Chaos Emeralds: The Chaos Emeralds are 7 stones that have been around for a very long time. There is very powerful energy in them that has both evil and good power. As a result, both good guys and bad guys are constantly looking for them. Sometimes, characters can become super powerful by using their energy. For example, Sonic becomes Super Sonic.
  • Super Emeralds: The Super Emeralds are present only in Sonic 3 & Knuckles. These are even more powerful than the Chaos Emeralds. When Sonic collects them all, he can become Hyper Sonic.
  • Master Emerald: The Master Emerald is a very special green gem that is much larger than the Chaos Emeralds. It holds a great power that can even control the Chaos Emeralds. It is on Angel Island, the floating island where Knuckles lives. Knuckles guards and protects the gem. He is also one of the only people able to control its power.
  • Rings: Also called "power rings" or "magic rings", these are golden rings which contain a special power. In the games, Sonic will die if he is attacked with zero rings, but with more rings, he can survive.
  • Monitors: These items are seen across levels. They give power-ups when opened, such as shields, rings, or extra lives. But some can hurt you.
