Avengers: Endgame is finally out in theaters, and we’re here to answer the biggest question we know you had going into the movie: which Avenger has the biggest potty mouth?
The answer… well, probably won’t surprise you if you’ve watched every movie in the MCU to date (or at least the Iron Man ones). See below for our full tabulation of every time an Avenger swears in the Marvel Cinematic Universe, counted up through Avengers: Infinity War.
There are almost no surprises on this list. The Avenger with the worst potty mouth, by far, is Tony Stark. He clocks in at 44 swear words, mostly of the “ass” variety. Perhaps it’s in his nature to be playful, perhaps it’s from his years of selling weapons in some of the darkest places in the world. Whatever the reasons may be, if the Avengers had a swear jar, Tony would be putting in the most money. He is a Stark, after all.
