Tony Stark is a Marvel Comics character brought to wide fame on screen by Robert Downey Jr., starting with Iron Man in 2008, the film that launched the Marvel Cinematic Universe. Short clips of his dialogue spread widely through fan edits, reaction videos and soundboards as the Avengers films grew in popularity. His mix of intelligence, humour and arrogance makes even a few seconds instantly identifiable. The clip remains popular because it can signal confidence or sarcasm without needing any visual context from the original scene.
