I could be wrong, but I don't think Metal Sonic has ever been labeled as a Badnik either. Actually, Metal Sonic HAS been labeled as a Badnik. On Sonic Central. Basically US's Sonic Channel. I would point out Metal Sonic can't be a badnik since he is not critter powered... but then again some of Eggmans mass produce robots often had alternate or no power source when busted open.

But then again I guess it depends on the definition of "Badnik". For example are the E-series really "Badniks"? Yes, they are critter powered but the Dreamcast era of robots were never refer to as badniks.

Same goes for the robots in Sonic '06 and Sonic Unleashed which appear different from usual designs of badnik.
