Sonic the Hedgehog is the titular main protagonist of the Sonic the Hedgehog series and 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 his speed. As his species implies, Sonic can also roll up into a concussive ball, primarily to attack enemies.

Born on Christmas Island, Sonic abandoned his home at an early age to persue danger and adventures. Becoming a carefree adventurer, Sonic has spent most of his life traveling around the world and far beyond, usually in his beloved Tornado with his best friend, Tails, as his sidekick. He has since become the champion of peace after stepping into the battle against iniquity, having used his abilities to defend his world and those far beyond from the forces of evil, especially his arch-nemesis, Dr. Eggman, and his empire.
