Team Iron ManvsTeam Dante (DMC)

Team Iron Man If you're familar with Marvel vs. Capcom then you'll recognize this as the Main Battle Poster for Marvel vs. Capcom 3, however it is a Mismatch

Iron Man vs Ryu - More likely Ryu wins
Wolverine vs Chris - More likely Chris
Thor vs Dante - I Really don't know

but The Main Reason Marvel Wins easily is that Wolverine, Iron Man and Thor all have teamed up multiple times and know what's it like to work together

Ryu, Chris and Dante don't have since they don't come from the Same Universe

Team Marvel wins
