Fleetway Super Sonic comes from Sonic the Comic, the British series published by Fleetway from 1993, where the Chaos Emeralds turned Sonic into a separate, sadistic alter ego rather than a heroic powered up form. That darker take kept a loyal cult following long after the comic ended, sustained by fan art, animations and game mods. Short voice clips of his threats circulate in the Sonic fandom and wider meme editing communities, where the character is shorthand for a hero completely losing control and enjoying it.
