Sonic the Hedgehog ソニック・ザ・ヘッジホッグ Sonikku za Hejjihoggu, born June 23 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. 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 pursue danger and adventures. Becoming a carefree adventurer, he has spent most of his life traveling around the world and far beyond, usually with his best friend, Tails, by his side. He has 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.
