Fleetway refers to Sonic the Comic, the British comic series where Super Sonic was reimagined as a separate, violent and out of control personality rather than a hero form. That darker take kept a strong following long after the comic ended, reappearing in fan games, animations, mods and Sonic horror edits. Knuckles, Sonic's rival and guardian of the Master Emerald, is a natural target in those stories. Clips naming their clash circulate on soundboards because the idea alone signals an instant shift from adventure to threat.
