Really? All I remember are alot of flame oriented weapons such as that big blade that seemed to shoot flames and his palms that shot flames.
He was good with the sword and seemed quick and obviously had some durability to take multiple hits from hulk no matter how weakened he might of been but hulk took all that damage from him because he brawled with him much is his way of doing things. Stark is tech, he won't duke it out with him like hulk he will keep his distance and use his full capability to put RK down.
Anything in particular you think red King can do that will be too much for Iron man?
