>>114924450Both are pretty fucked up from over the years. I'd give Doom the tecnical advantage, and Luthor the physical advantage. So Doom would know more arts, and he's obviously more unhinged, plus he's got magic and shit, so he'd also be able to tap into some auras or whatever. Luthor though I think would be in better shape. I've always had the headcanon that Doom had general faults that made him all the more self-hating and obsessed with showing people up. Like a busted knee or something. Meanwhile Luthor, aside from getting his hair burned, is supposed to be the human Superman.
TL;DR I'd give it to Doom through some uber-magic-technique once he goes feral.
