Admittedly, 1st page is a WIP for the FNaS: FF X HN crossover.

But anyway, here's the full look of Clone Sonic "Tune-Up!" from Fierce Forces.
He appears:
In Five Nights at Sonic's 1: Insane Immerse "Route of Recollect" (addon) fancomic as the main antagonist.
In Five Nights at Sonic's: Fierce Forces "Imagine It!" (main) fancomic
as the titular antagonist.
& In Five Nights at Sonic's: Fierce Forces "Entertain Entrapment!?" fangame
as the main antagonist.

2nd page: Microphone and other side of Grind Shoe.
