4) She-Hulk
With still no solo outing for The Hulk in Phase 3 (he will, however, have a leading role in Thor: Ragnarok), it wouldn’t hurt for Marvel to shift their focus to his cousin, Jennifer Walters, instead. She received her Gamma irradiated abilities after a life saving blood transfusion from Bruce Banner, but the key difference between them is that she has the ability to decide when she transforms and retains her intelligence when she does so.
A lawyer by day and superhero…well, also by day…She-Hulk is a great character and one who is definitely deserving of the big screen treatment. If Marvel could get the special effects sorted (and an argument could be made that an actress would be able to play both roles with make-up effects instead of CGI), then Jennifer could just as easily find her place on the small screen in a big budget Netflix series, too.
