That was STC though I believe archie had a similar explanation for their sonic as well. game universe sonic on the other hand never had an explanation. Never played SPA because I heard it was mostly a sonic 2 clone. but I'll youtube that and see if thats true. EDIT: Wow was I ever proven wrong. yeah it does look like eggman switched uniforms between the 2nd to last and last fight. strange. I would love to see a SPA: Genesis version someday.
