Kurse vs Infinity War Iron Man
Iron Man with the armor from Infinity War fights Kurse. Iron gets to see all of Kurse's scene in TDW and Kurse gets to see all of Iron Man's scenes in IW and both of them know about this stip as well. Fight takes place in abandoned Miami city. Win by ko, kill or submission
Damn, I'm actually not totally sure. I still think Kurse is physically the most impressive MCU character to date but IW IM fought Thanos with 4 gems and actually didn't get stomped (he still got beat handily, but he made a small fight of it). Then again, Kurse stomping Thor who had full access to his hammer and abilities is nothing to scoff it. Even pre-buff Thor. It's also worth noting that a lot of the attacks Thanos used to take down Stark were physical attacks, like when he tore the blade off with his ungloved hand and stabbed Stark with it or the flurry of punches he used right before that to smash the IM helmet. I feel like Kurse is strong enough to take the armor appart with successive hits. On the other hand, I don't think Stark could hurt Kurse. He got plenty of hits on Thanos using speed and mobility, but Thanos didn't seem hurt in any way. It's a long fight but Kurse ultimately takes it IMO. Either that or a stalemate.
So, if they can watch all each others' scenes, does that mean Tony will know Kurse carries around a black hole grenade capable of killing himself? Because Tony, when not hampered by PIS, has consistently shown himself to actually be a pretty crafty and intelligent fighter. For example, using the altitude weakness, attacking his targeting AI, using the big arc reactor etc. against Iron Monger in IM1, using the repulsor rebound in IM2 during the final fight against Whiplash, keeping track of the Hulk in order to give him a "soft spot" on the Leviathan in Avengers, the Jonah and the whale technique on another, using his suits exploding to kill Extremis soldiers in IM3, his quick thinking during the Hulk fight and when he was rescuing civilians in Sokovia in AoU, as well as figuring out a way to deal with the falling city. There are more examples, but you get the picture.
So, I could see him trying to use it against Kurse. However, he does not want to get into a brawl with Kurse, because that he would lose IMO.
