Idk that extremis suit sounds pretty dangerous to superman but of course superman could create an anti kryptonite armor so ill go with supes but no doubt iron man could win

I'm calling spite

superman

Tony's a genius in his own right, but I think Superman has constructed lead suits in the past in both the comics and cartoons.

^ that one is a lead-lined titanium suit that can repair itself. Given Superman's powers, I think it'd be insanely tough to beat.

If Supes get prep aswell it's totally going in his way, I mean even if he doesn't have the resources to make a kryptonite proof suit he can just see tony coming a thousand miles away and melt his suit off his body...

Indeed! But i don't think the OP made it on purpose.

My friend just watch iron man 3, tony could find a way to beat superman, so like i had to give superman 1 week as well otherwise i might ban xD?

Superman for the win. . . .

yeah pretty much this

Unprepared - Superman

Prepared - Superman

Only way Tony could win is if hes the only one prepared, plus he'll probably need a backup plan which i'm sure he would have.

Intelligence comes a long way so you can't really know for sure, if you have the right strategies and plans things could go well.

@alak: I have not read that arc for a while, but according to my memory wasn't it Batman that got Supes the suit?

Superman.

I'll be honest when I say I don't remember lol. I just know that Supes has had lead suits in his history, and that's the coolest looking one that I could find right away. I guess the one he had in his animated series would work against kryponite... except Iron Man would shred it to pieces within a few repulsor blasts (assuming the hits land, of course).

Superman wins no matter what the circumstances are.

Really ?

Anything he wanted to.

Superman destroys Iron Man.

Spite.

oh poor Iron man.....

i voted for all 3. everybody wins. or draws. yay!

What could Superman do to Iron Man?

He could kill him; that's what he could do to him. Even with Kryptonite-enhanced Extremis armor, Tony will still get a can of whoop-ass opened on him.

Supes has the lead suit, and on top of that, he is developing a tolerance to Kyrptonite if I'm correct (only a slight one though, but still), and it wouldn't take much effort on Superman's part. He would fly towards Tony at the speed of light, take him in the deep depths of space, and just watch him die a painful agonizing death.

This is coming from someone who hates Superman.

this.

I had this handy from a Batman thread, so I just brought it over here. Superman, fighting 3 Kryptonite Men (Red, Blue, and Green varieties), an alternate Universe Doomsday Superman, another Kryptonian (Xa-Du), and indirectly a 5th Dimensional Imp. This is how Superman is commonly portrayed as responding to Kryptonite.

Basically, I dont think Iron Man is powerful enough to even utilize the Kryptonite advantage he'd get.
