Ironman is complete shit against ryu, seriously he can dodge bullets at point blank range (watch the street fighter alpha movies) and his hadouken is as strong as any dragonball z character's blast, so ironman would be beaten to death or disintergrated even in his suit. I dont see doom doing any damage except for his gauntlet gun.. with no prep he is easily beaten.
Cable however rapes the whole team and thats that..
