Sonic the Hedgehog is the titular main protagonist of the anime series Sonic X and its comic series published by Archie Comics. Lightning fast on his feet, but super-slow to lose his cool, Sonic is always revved up in speed and is ready for a run-in with his archenemy, Dr. Eggman whenever he tries to cause trouble to the world to show his heroic deeds.

During a conflict with Eggman, Sonic was transported along with his friends, by Chaos Control, from their home planet to an alternate planet, Earth. Lost and alone in this new world, he was saved from drowning in a pool by Chris Thorndyke, and the kind youngster allowed the heroes to take refuge at his home as they defended their new residence from the evil plots of Dr. Eggman. After many adventures, Sonic eventually returned home, where he would save his universe from the Metarex.
