2. Leader (The Incredible Hulk)
I really disliked Samuel Sterns in The Incredible Hulk; he was very, very annoying. However, his hinted transformation in to his comic book alter-ego - the Leader - is something that surely can't be kept away from the big screen forever (otherwise that scene was pretty pointless). Up until recently, I didn't want to see Sterns again - certainly not as his annoying, powerless self - and I said as much in a recent article but, after giving it some thought, given how much awe he was in when it came to seeing the power of the Hulk, it would be interesting to see him fully transformed in to the Leader with power of his own and a new found, evil purpose. According to the tie-in comics, Sterns is currently in S.H.I.E.L.D custody, having undergone further mutation that what was shown in his one and only film appearance, so a future movie appearance as the Leader is certainly not out of the question.
