<<Is Supes bones different from everybody elses?>>
yes. strictly speaking, if his skeletal structure was the same as yours and mine, well . . . he'd have a lot of problems lifting those 100 000 ton weights . . .
<<Yes, and under his own admission, Gladiator is more powerful than him.>>
not in continuity so it's irrelevant.
<<He's stalemated both Thor and Thing at the same time.>>
they smashed him, he blasted them. hardly a drawn out fight, and hardly h2h.
<<He's stalemated Drax>>
so did hulk -- prof hulk.
<<The fights between Thanos and Hulk have proven what, that Hulk has nothing on him.>>
he's never battled savage hulk, only prof (who's not in regular supe's league, let alone new-god-tech-amped supes' league!) and has admitted to being leary of the fight. all you've done is show that thanos can use blasts to fight off thor and thing, and fight and stalemate guys hulk has done the same to. that's certainly not gonna convince me thanos is as strong as dd who broke the arm of an AMPED supes -- cripes, he had a MOTHERBOX for the fight and STILL got his ass completely stomped!
again, it's conceiveable thanos could break his arm, but it remains unlikely in my book as it is hard to find feats that clearly demonstrate thanos is THAT much stronger than superman. i'll agree he's likely stronger than regular supes, but the odds of his breaking his arm decrease even more when you add a motherbox to superman.
