Cyclops VS Havok - Cyclops, their powers may not affect each other, but Cyke has been trained to fight since there were X-Men, so he'd kick his brother's ass.
Psylock VS Polaris - Psylocke, telepathy owns all.
Beast VS Wolfsbane - Beast, come on the guy can bench a ton.
Rogue VS Strong Guy - Rogue, Guido's the type of guy that'll underestimate a pretty face, a big mistake here.
Wolverine VS Multiple Man - Multiple Man, just because Logan wins too many of these things.
Gambit VS Quicksilver - Quicksilver, Gambit may be fast with the ladies, but Pietro is fast with everybody (that sounded dirty didn't it?).
