Sonic the Hedgehog is the main protagonist of the popular video game series of the same name, all TV series of the same name, and all comic books of the same name, as well as Sega's mascot. He is an anthropomorphic hedgehog born with the ability to run faster than the speed of sound, hence his name, and possesses lightning fast reflexes to match. As his species implies, Sonic can also roll up into a concussive ball, primarily to attack enemies.
