umm, getting back on the topic . . .
in a straight up battle MM should probably win, (ie if we are assuming they knew nothing about each other and were dropped on a barren planet with out of the blue) but doom has battled telepaths before (may even have built in protection, though i can't say for certain - with the classic 'prep time' he certainly would) but i think doom would probably discover quickly that MMs weakness is fire and find a way to exploit it to his advantage. no question who's more powerful, but weakness to fire is too big a handicap against someone as smart and clever as doom. i love MM but gotta say doom here.
