I combined Magneto and Doom: Now there is a guy named Moom (yah I know his name is lame but his power set is incredible) he is as smart as doom and has doom's and Magneto's powers.
His team mates are Moonstone and Electro, and Rulk. NO PREP
Batman with his insider Suit
Jean Grey (not phoenix)
Sif (Thor's Girlfirend)
Battle happens near the fire pits on Apocalypse.
Who takes this and HOW? I say Moom stands a good chance her.
