ULTIMATE Marvel vs Capcom 3...!? FUUUUUUUU-

[Vipershark]

I'd want Grey/Ashe to be in, but I don't think ZXA is "mainstream" enough to put in :/
Model A would be great for a fighting game, though.

You had me at Model A then you started talking about Mainstream. Explain to me how this matters?

because they would want a well-known character

it's obvious why classic is in, and Volnutt has a huge cult following

ZXA has nowhere near the following that the other mm series do.
