King Sonic, also known as Evil Sonic, is a version of Sonic the Hedgehog from an alternate reality in which Sonic had been caught in the ROCC accident instead of Ovi Kintobor. In this reality, King Sonic was a ruthless dictator who controlled an Orwellian-style Mobius with an iron fist. He looks identical to Sonic, but wears a red cape and crown. Little information is given about him, but he appears to command a large army of Badniks and resides in a dark castle built in his image. His constant foes are his worlds Freedom Fighters, led by Amy Rose and Tails. During their dimension hopping adventures in the Time Zone arc, Sonic and Amy encountered and defeated the villain by driving him into an insane rage during battle, turning him into Super Sonic. Given the reversed nature of Sonic in this dimension, 'King Super Sonic' was not evil like the mainstream version, instead appearing as a pacifist. It was suggested that this world's Tekno the Canary could find a way to make him Super Sonic permanently.
- King Super Sonic has normal eyes instead of scarlet spirals, like the Super Sonic from the video games and the Archie comics.
