For me, it would probably be: Carnage I would like to see his moves resemble those he has in Marvel Ultimate Alliance 2, which included spikes sticking out on all sides, a rapid slashing attack, and a boomerang-looking projectile. I think these would perfectly suit a fighting game. Ghost I think Ghost's phasing and invisibility would make for some interesting moves. Hawkeye All of Hawkeye's moves would obviously use his various trick arrows, which ever ones the devs thought were the coolest. MedusaMedusa would use her hair to strike out, or grapple/constrict. Although these alone aren't very powerful moves, I think the fact that it was her hair she was using would make them interesting-enough. RockslideRockslide would obviously have Hulk-like smashing moves, but could also incorporate throwing his hands as projectiles or something along those lines.
