The line comes from Marvel's The Avengers from 2012, spoken by Tony Stark, played by Robert Downey Jr., during his confrontation with Loki. When Loki threatens Earth, Stark calmly answers that the Avengers have a Hulk, foreshadowing Bruce Banner's transformation and the battle that follows. The moment became widely quoted because it turns a superhero reveal into a deadpan punchline. Years later it still circulates in memes, reaction videos, and gaming edits, where it signals that help is already on the way.
