Sonic the Hedgehog (Sonic X)

Sonic the Hedgehog is the main protagonist of the anime series Sonic X. Lightning fast on his feet, but super slow to lose his cool, Sonic is always revved up and ready for a run-in with his archenemy, Dr. Eggman. Sonic's fear of water is even more present in the series.

Brave new world
Sonic hails from an unnamed world in a parallel dimension to Earth. His backstory is a mystery but it's known that he befriended Tails, Knuckles, Amy, Cream and Cheese and many small animals as well as battling Eggman. One day, he attempted to rescue his friends Cream the Rabbit and Cheese the Chao from Doctor Eggman, as well as foiling the doctor's latest plot to control the world with the power of the seven Chaos Emeralds. Unfortunately, an accident initiated Chaos Control, which transported Sonic, Eggman, all of Sonic's friends and all within a ten mile radius to Earth. On Earth, Sonic befriended Chris Thorndyke, who rescued him from drowning in a swimming pool and then allowed Sonic, Tails, Amy, Cream and Cheese to stay hidden with him in his house. He also forged a friendly rivalry with Chris' second uncle Sam Speed, a cop who chases criminals in a racecar. He is initially hidden in Chris' home and boggles the human race with his being, people think he's an alien or machine. While Sonic was mostly covert, Eggman made himself known as he tried to conquer the new world. Sonic eventually destroys Eggman's first base and is hailed as a hero along with all of his friends. Sonic destroys Eggman's second base by becoming Super Sonic after finally gathering all the Chaos Emeralds causing Chaos Control to bring some aspects of his world, like Angel Island to Earth.

Fighting for Earth
After the adaptations of, Sonic Adventure, Sonic Adventure 2, Sonic Heroes and Sonic Battle, it was discovered that Sonic's world and Earth were merging which would lead to the stopping of time. The only way to save both planets was to return Sonic and his friends home. After everyone but Sonic had went through, Chris took him away, eventually to his parents old summer home. Chris tells Sonic how much he will miss him and how much of a friend the hedgehog was. Sonic gathers the Chaos Emeralds and after taking Chris for one final run, returns to his home universe.

Upon returning, Super Sonic easily destroys Eggman's latest battleship, saves Tails and then meets Amy, giving her a rose and telling her that he loves her.

Universal Roaming
Six months later, Super Sonic battles Dark Oak in the atmosphere. He spreads the Chaos Emeralds throughout space and falls back to the planet. He is found and nursed to health by Dr. Eggman. Later the heroes gather the Chaos Emeralds in a space journey very loosely based on, Sonic Heroes and Shadow the Hedgehog. In the end Super Sonic and Super Shadow destroy Dark Oak and they all return home. Sonic watches as Chris is flown away back to Earth and declares war on Eggman for making Chris leave so soon. "I'll never forgive you, Eggman!" In this season, Sonic seems to care about Amy alot more than in seasons one and two.

Characteristics and relationships
Sonic is a habitual daredevil who is honest, loyal to friends, keeps his promises, and dislikes tears. He took the young Tails under his wing like a little brother. Even though he isn't interested in the marital proposals from Amy Rose, he really seems to exchange partially her feelings, as he even dives into water to save her when she was drowning in episode 9 (even though he couldn't swim); and in episode 52 (English version) he also promises her to never leave her alone again (or actually tells her that he loves her in other versions). With Knuckles he shares a friendly rivalry (similar to the game one), the two can be anyhow great team mates, but Sonic simply can't resist teasing him whenever he has the chance to. Even if he meets Chris at the beginning of the series he become fastly his friend.

In times of crisis, he focuses intensely on the challenge as if his personality had undergone an astonishing change. Sonic's greatest strength is his running speed, which is faster than the speed of sound. He appears as a blue blur when he runs. He can use the Spin Attack like in the games and appears in 3D, in this state he can break through virtually anything and a ring can increase his power similar to SatAM.

When seven Chaos Emeralds are collected he is able to transform into Super Sonic, a faster, stronger and invulnerable version of himself that can fly, teleport and move faster than the speed of light. He can also heal people with a touch. He has used super transformation against Perfect Chaos, Biolizard, Eggman, Dark Oak, and Super Shadow.
