Iron Man/Tony Stark was one of the Marvel Cinematic Universe's most important heroes, having kicked off the shared universe with his first solo movie. Over the decade since that film released, he's had some pretty incredible moments. We're looking at his greatest moments in the MCU.

The Incredible Hulk, which starred Edward Norton, was initially thought to be the safer bet in terms of adapting a superhero. However, after the two movies released, it was Iron Man that stood supreme. One of the movies that helped the film to become so memorable came at the very end. At a press conference, Tony Stark declares, "I Am Iron Man." This line, of course, returned in one of the most unforgettable scenes of Avengers: Endgame.

As Avengers: Endgame saw the death of Tony Stark and there's no indication actor Robert Downey Jr. will return anytime soon, so as it stands these are likely to remain his greatest moments for the foreseeable future. However, anything can happen in the MCU.
