very interesting ... in the end... i believe Iron Man and Thor
Iron Man perhaps has the advantage against Wonderman with his blasts
and Thor would have a very very hard time against the Prince of Power, Hercules... but in the end ... with Mjolnir and all his powerforce.... he would beat Hercules... i do believe
Wonder Man has quite a record against Iron Man. Wonder Man has put Iron man down at least a couple of times to my knowledge. AT LEAST... With these 3, Iron Man is considered the weak link, and Herc can stall Thor long enough until WM can finish of Iron Man, then they both double team him.
That's of course if Iron Man has one or two particular armor's that come to mind, or a good amount of prep, possibly Tony could come up with something, then the Thor team will have a pretty good chance.
