Tony can move faster than the human eye. Plus if Scott manages to tag him shields will reflect as Tony appears behind Scott and blast his brains out. Colossus and Logan are grounded and Tony will Sonic blast their eardrums.
Warren gets his head blasted in aeriel combat.
I'd say Tony just by how powerful his Extremis armor was. This new Bleeding Edge armor is meant to take full advantage of his Extremis, nearly limitless energy production, and technology far beyond the Extremis armor.
I'm more curious what that cannon he had strapped to his arm could do when he was effectively playing possum to that Hammer girl, but instead, we just got to see his weapon, not what it does yet.
In his past armors, Cyclops would probably pose the biggest threat to him, just given his "point and shoot" high speed powers. I'd say with his repulsor fields, it's really not that big of an issue. Archangel? Sonics, matched with a beatdown, or just straight up repulsor fire. Wolverine? Unless Tony felt it was an awesome idea to for whatever reason to engage Wolverine in a land battle, he'd either shoot him from the air, burn him, sonic him, or just beat him down. With the current upgrade, his armor was easily capable of outmaneuvering Steve Rogers, and his current armor not only can do the same, it's apparently more fluid, and it self repairs. So Wolverine might cut or stab, and Stark's newfound healing factor would ensure that's not simply the end of the fight. Coupled with Tony's guns, and highly superior strength backed by metal plating on his fists, Wolverine is going to hurt. And, like I said, his healing factor, it may not be as powerful as Logan's, but it's not a nonfactor either. Collosus? Well, Tony would probably just pound on him. They're similar in strength, but Tony just has the toys to pound that one.
At the same time? Tony would probably employ air tactics, run down Warren, fire back at Scott, pepper the ground to separate Piotr and Logan, pound on Piotr, then work on Logan.
Kitty would be interesting, but it's not like Tony's never fought anything like that before *cough*Ghost*cough*. And Tony in the past has utilized telepathy blockers, except for in Civil War for whatever reason. Storm would pose an interesting battle. Emma could go diamond form, and that would be likewise interesting. Maybe.
I agree, Tony would still stomp that team. Right now, Iron Man is easily reaching powers approaching Thor.
I wouldn't say he wtf pwn Rulk, given that Ross was up a few panels later and he didn't really fight back, but it was still an impressive showing for Iron Man. His current armor seems amazing.
