Tony Stark’s 7 greatest moments in the Marvel Cinematic Universe

Enter Hulkbuster

Tony’s created a lot of armor similar to Iron Man’s, but the Hulkbuster is one of his more ingenious inventions — especially knowing how Bruce Banner tends to lose control of his green friend from time to time. It’s an epic moment when Tony shows up in this Hulk-sized armor to stop his friend from destroying a city (even if their fight ultimately causes him to fail at that objective).

But failure is a crucial part of the Avengers team’s growth, and much like Tony’s announcement that he’s Iron Man, this showdown between Hulk and Tony in the Hulkbuster suit creates ripples that impact the entire Infinity Saga. The mistakes Tony and Hulk make here make them aware of their responsibilities as heroes all over again, and they force the team to at least try being more considerate going forward.

It’s not just the importance of this scene that makes it great, though. Anyone who loves a good action sequence will surely enjoy watching Tony have it out with his friend. It’s a fight for the books, and it’s one of the only ones where fans can genuinely see the Hulk struggling.
