Shadow the Hedgehog is a character who appears in the Sonic the Hedgehog series. He is an artificially created black and red anthropomorphic hedgehog whose hover shoes propel him at extreme speeds and was initially depicted as a villain but later became an antihero, suffering from a tragic backstory; occasionally he becomes ally to Sonic and his friends but remains at odds with them due to their differing moral compasses with Shadow acting as Sonic's arch-rival.
