I swear I've heard Galvatron's voice in numerous bad HK dubs. In particular, I think he dubbed Jackie Chan's voice in the original (very shitty) Drunken Master (I and II, iirc).
Galvatron, why are you even in this line of work if you hate it so much? You're constantly depressed and angry, and you bring everyone around you down. I think you've lost touch with why you became a villain in the first place.
