Not gonna lie, this one took some real thought. Well done OP.
The Leader. In-between my megalomaniacial plots, I'd work on cancer, MS, climate change, and everything else multiple-order-of-magnitude greater genius could give to humanity.
Sorry, no, Reed is still one of the good guys, although you make a great point. In the real world, yes, Reed would have been locked up for child endangerment when he took Johnny on their fateful ride into space. He was only 16 at the time. If Reed somehow was allowed to practice his experiments after that point, the courts would be backlogged to this very day with all of the lawsuits against him. In all likelihood he would have been discredited for cause and left destitute and penniless. Sue would probably be married to Namor and Queen of Atlantis -- her true "heart's desire" according to the Claremont story, which remains canon.
There are someday's that I think Bullseye's marksmanship, would really cool to have, (he can take out people with peanuts, or {if you read his mini series that came a couple of years ago now} cause traffic accidents by throwing paper clips)

Ooh, good one. The High Evolutionary might be an even better choice, along those lines. He's got the superhuman IQ, the very specific training and knowledge, all sorts of kewl psychic powers, and, best of all, he's not green or got a giant noggin, so he can run out to Dunkin's for a coffee and some munchkins without it turning into a Fortean event.
Dr. Doom hands down for me, or maybe Superior Octopus/Spider-Man if he counts.
