Both get a GL ring. Both train separately with Hal Jordan for 3 months. They also keep their standard equipment for fight (i.e. armor, shield, etc). Who wins?
Steve's will is greater and thus will have stronger constructs.
But I think Tony's imagination for weaponry and defense would be greater since he already designs a bazillion different types of weapons and shields. Plus Tony also knows physics well, which can help in designing his constructs so that his will is less dependent on them. Cap would be more simple with his constructs.
IMO Iron Man wins. The armor just adds extra protection just in case Steve can breach his shields construct.
Cap probably has a stronger will (Which isn't saying much, considering he's being compared to a booze hound), but Starks tech knowledge more than makes up for it. Just think of the insane armors and gimmicks he could build now, without worrying about the limits of modern technology or materials.
Well, the other way of assessing his alcoholic problem is that it takes a very strong will to stay on the wagon.
And to his credit, he's done just that, so his will should at least be capable or matching an elite GL. Once you're at that level, it really less about pure willpower and more about tactics, strategy, and knowing how to use the ring.
I'd bet Sinestro isn't as strong willed as Kyle Rayner, given Rayners past feats of pure will like creating fully sentient constructs and maintaining them, but Sin craps all over him in a fight.
dude why must you be wrong at everything? even when the answer is so obvious you still manage to be on the wrong side?
lets see both characters get an item that its power is based on the freakin will power, captain america is the definition of will power itself is going up against a drunken playboy geee i wonder who the hell is going to win its so hard i just cant make up my mind
wtf? his will power can match an elite GL because he didnt lose himself into becoming a complete alcoholic homless bum?
the fact he has alcohol problem alone is already a down fall for him because if he had a strong will he wouldnt be an alcoholic in the first place because he would have to will power to just drop it , and somehow you compare him to an elite GL ???
its like you think there is some kind of law that say any super hero automatically has a peak will power , thats not the case.
it doesnt matter what structors tony create or what he will try to do because cap will only need to create a fist form with his GL and when he punch tony with that power he will bust his constructs, his armor, his mustach, and his ansestors
