Re: Mega Man
I played for years on a Mega Man MUSH (kind of an online text-based game, like a more complicated MUD), so consider myself something of an expert on the Blue Bomber.
Anyway, Zeropoint is correct on all counts. Mega Man does, indeed, sink like a stone in water, and the teleport system is part of Dr. Light's lab and would be paid for by Dr. Light.
As far as the PD/ED goes, well, I'd probably just make it whatever's typical for the campaign he's in. It could be argued that his PD and ED are virtually nonexistant, since he takes damage from walking into enemies ... but not seriously. I would probably increase his CON and END some, and lose the zero-end-on-everything paradigm. While it seems typical in HERO for robots to buy zero end on everything, I wouldn't consider it a requirement.
