Superior Iron-Man has been part of the game since inception, or just about to make no difference. He was almost a pointless introduction since him and Iron-Man are pretty much exactly the same except for their class difference.
I know that in the beginning of the game certain capabilities were not easy to implement. Now that the developers are better at making unique champions I feel like it's time for SIM to have a change. I shared a link to the Marvel wikipage that discusses the Mark 50 armor. Which is fully liquid metal endo-symbiotic biological armor. The suit is incredibly intuitive and acts in a similar way to the nanite technology suit from infinity war. The only difference being that the suit is basically alive. The suit can change to a hulk-like physique when more material is added to it and can be controlled via psionic link. The suit has so much potential and all we get from it in the game is just basic. It's very disappointing when I see this character in my roster. I know what he is supposed to be but he's just regular Iron-Man with a cosmic class. I really hope he is one of the cosmic champions under the radar for an overhaul. He really needs one.
