THE HULK
Real name: Bruce Banner
Portrayed by: Mark Ruffalo
Prior film appearances: The Incredible Hulk (2008), The Avengers (2012), Iron Man 3 post-credits (2013)
Bruce Banner has been somewhat of a ticking time bomb, even pre-Hulk. The reclusive scientist had a traumatic childhood which culminated in the murder of his mother by his abusive father (in the comics) - it's safe to say that this dude has many issues. There's a constant power struggle between Bruce and the Hulk, for the former to control his highly dangerous alter-persona. And what little progress he's made so far doesn't cut it when "he doesn't wanna turn into the Hulk. [But] all that people want him to do is to turn into that green rage monster."
Secret: He Fears That He Might Lose Control Of Himself Forever
But for all Bruce's efforts, this tug of war might not end up with him winning, as Mark Ruffalo shares. "He's definitely worried that the day is going to come when the Hulk gets the better of him, and maybe won't release him, maybe won't bring him back. The Hulk knows this too." The good news is that the Hulk has finally found his family amongst the Avengers, but the introduction of Scarlet Witch (more on that later) into the team will force Bruce to confront his worst nightmares.
