HEY GUYZ! Tell me who ya fink wanz, cool.
Akuma and Raiden. Prabably Raiden by himself in a realistic framework. He is a god after all. Akuma, Scorpion and Sub-Zero can keep the others from piling up on Raiden and will probably kill some of them.
Thing and Human Torch would proabably be the most trouble (but that's where Raiden comes in).
I'm pretty sure that the Human Torch and Static Shock could very well win it for their teams, but it'd be a pretty tough fight. Also, i'm thinking Dante is a significant factor, too. This is a difficult question to answer.
