Hm, looks interesting. It is a shame that my namesake has been reserved already, but perhaps someone else may suffice, though I would be all over that if Batman4560 changes his mind.
Say, Sebastian Shaw or ... Graviton. Especially the latter, since he's quite underused for someone who controls the gravitonic force to a similar extent as Magneto electro-magnetism. I figure if people like Thor or Blue Marvel aren't off-limits, old Franklin Hall might still make the cut, especially as a villainous character. He's certainly too powerful and self-possessed to want to just roll over and submit to Apocalypse.
I figure Graviton might start out having taken control of a territory, setting himself up as a messiah figure of sorts that provides a safe haven as long as people are properly appreciative.
Something that could easily crumble around him during an invasion and set him on a path of petty revenge.
Edit: Oh, point of curiosity - how did Richards die?
