Superman ain't solo a team with WM, not the one in the Mighty Avengers at least, but the good powerful ionic energy form one.Also Namor powered by the black suit which keep him fresh and wet and Hercules who is currently back at full power, Superman will get wrecked.Each of this guy has enough to durability to go toe to toe with him in a 1 vs 1 battle.WM flight speed exceeds escape velocity, and his ground speed is pretty high too.Namor is above escape velocity as well and Herc has a high degree of superhuman reflexes and each one of them is a high Class 100 strength possessor with fighting skills that ranges from considerable(WM)to master fighter(Namor and Herc).Crystal's element control and Vision's phase shifting abilities would grant them to beat Supes really fast.For the Hulk, well I don't believe the Green Scar would be hurt by the phase shift, and none on the team has nrg emission enough powerful to hurt him, except WM.In an What If WM nrg form was damaged by the Hulk and the explosion killed them both so...
