Sonic is the fastest hedgehog in the world, and he can easily break the wall of sound to pieces, simply by running. He hasn't a fixed house, and he's always traveling around the world, looking for adventures. He's always ready to aid his friends, but he's got an impulsive and stubborn temperament, which often brings him to fall into troubles. Sonic is a hero admired by everyone, who always manage to spoil the plots of his eternal enemy, Doc. Robotnik.
