Cosmic was a green hedgehog that attempted to upstage Sonic the Hedgehog and the Freedom Fighters. Cosmic played up the image of a hero, wearing a yellow flowing cape, "C" emblem on his chest and a Superman-style curly forelock. He claimed to be the "fastest spiky thing alive" and challenged Sonic to a race to the end of the Emerald Hill Zone. Sonic, so irritated by Cosmic's posturing, agreed. During the race, however, it became clear that Cosmic possessed neither Sonic's speed nor his stamina, and he lost by a considerable distance. However, this was all a ruse by Metamorphia to isolate Sonic from his friends. She revealed her true form and attempted to catch him, however Sonic was able to escape and thwart her plan.
