Sonic the Hedgehog

Sonic the Hedgehog is the main protagonist from the Sonic the Hedgehog series. Hailing from Planet Mobius, Sonic acted as the hero and ruler of the planet, as well as the leader of the Freedom Fighters. He is most known for his superhuman speed, which allowed him to break the sound barrier. In Worlds Collide, Sonic learned of the disappearances of his friends Miles Tails Prower, Knuckles the Echidna, Amy Rose, and Shadow the Hedgehog. Deducing that Dr. Eggman was responsible for their disappearances, he then tried to locate them and ended up fighting Mega Man shortly after the Genesis wave hit their respective worlds at Green Zone, believing Mega Man to have been one of Eggman's Badniks due to his robotic nature. Mega Man, likewise, believed him to be an incredibly advanced robot who might have been working for Dr. Wily. According to Mega Man, Sonic was faster than any of Wily's robots he had encountered by that point, most notably Nitro Man and Quick Man.
