Red Hulk

Red Hulk is, of course, actually General Thaddeus E. “Thunderbolt” Ross – a character who has appeared in movies before – but he has never transformed into his big, red, powerful alter-ego on screen.

Ross was revealed as the initially mysterious Red Hulk back in 2008 (the brute had appeared in several issues before the reveal) and was created specifically as an intelligent, tactically astute adversary to the more well-known and long-established green Hulk. He went on to be a member of the Avengers.

He would look awesome with modern CGI special effects. He would basically be a red version of the Hulk that we already know, but with heat and flames emitting from him. Instead of getting strong when he’s angry, this version gets hotter (to the point he can turn sand into glass) and he can absorb various types of energy to increase his strength. A green versus red battle on the big screen would also be awesome to see.
