"Sonic the Hedgehog, also referred to as Classic Sonic, is a character that appears in the Sonic the Hedgehog series. He is an anthropomorphic hedgehog and Sonic the Hedgehog's counterpart from another dimension set in the recent past.


Basically a past version of his modern counterpart from his younger days, Sonic first appeared during the Time Eater incident where he helped his counterpart foil one of Dr. Eggman's plots before returning to his own universe. Since then, he has continued his adventures alongside his friends, and even reappeared in the mainstream universe to help out where needed." -- Sonic the Hedgehog Wiki



Debut: "Sonic Generations" (2011)
