10 Quotes That Define Marvel Cinematic Universe Characters

2. "I Am Iron Man" (Tony Stark)

It was a tough call between this line and the "genius, billionaire, playboy, philanthropist" line in the Avengers movie but, bearing in mind the character development that occurred in the Avengers movie after Stark said this, as well as the subsequent character development that occurred in Iron Man 3, this line from the first Iron Man movie is more apt for Tony.

Tony proved himself to be more than the arrogant and self-righteous man that the "genius, billionaire, playboy, philanthropist" suggested he was and he truly became a hero. In the Avengers movie, he took what he thought was going to be a one-way trip in to Loki's portal to save the world and he fought valiantly again in Iron Man 3. He truly earned the title of "Iron Man" and the superhero status that came with it (and this quote expresses that without disposing of Stark's vanity, which will always be a trait of his). Full Dialogue Tony Stark: "There's been speculation that I was involved in the events that occurred on the freeway and the rooftop..." Christine Everheart: "I'm sorry, Mr. Stark, but do you honestly expect us to believe that that was a bodyguard in a suit that conveniently appeared, despite the fact that..." Tony Stark: "I know that it's confusing. It is one thing to question the official story, and another thing entirely to make wild accusations, or insinuate that I'm a superhero." Christine Everheart: "I never said you were a superhero." Tony Stark: "Didn't?" Christine Everheart: "Mmm-mmm." Tony Stark: "Well, good, because that would be outlandish and, uh, fantastic. I'm just not the hero type. Clearly. With this laundry list of character defects, all the mistakes I've made, largely public." James Rhodes: "Just stick to the cards, man." Tony Stark: "Yeah, okay...The truth is... I am Iron Man."
