Avengers: Infinity War - 13 Previous MCU Scenes It Completely Changed

2. Banner's Control - The Avengers

For all of Tony Stark's development as a character and Loki's various evolutions, the character who has changed the most in the MCU is Bruce Banner. And going back to watch The Avengers now that we've seen Infinity War - and Banner's Hulk crisis - you really get a sense of how far he's come.

Back in that movie, Banner was a picture of restraint, shurgging off Tony Stark's attempts to provoke him and being able to pretend to get angry with Black Widow without actually Hulking out. Ultimately, he then reveals that he's "always angry" and can turn Hulk on like a flicked switch.

Now we know that Hulk didn't appreciate being "used" by Banner when there were big threats to deal with, his casual ability to change looks almost flippant. It makes Hulk's issues with being used look even more justified.
