Tony Stark builds dozens of armors across the Marvel films, and every fan has a favorite. This guide walks through the major Iron Man suits in order — what each one did, where it appeared, and what made it stand out — so you can find the Mark that means the most to you.
The First Suits: Mark I to Mark III
Mark I (Iron Man, 2008). Built from scrap in a cave while Tony is held captive. It’s bulky, gray and crude, but it’s the suit that started everything.
Mark II (Iron Man). The silver prototype Tony builds back home to test flight. It proves the concept, but it runs into trouble at high altitude.
Mark III (Iron Man). The first red-and-gold suit, and the look that defined Iron Man on screen. It carries Tony through the film’s final battle.
The Iron Man 2 Era: Mark IV to Mark VI
Mark IV (Iron Man 2, 2010). An updated red-and-gold suit, seen early in the film.
Mark V (Iron Man 2). The famous “suitcase suit.” It folds into a briefcase and unfolds around Tony in seconds, in one of the most memorable armor-up scenes in the series. It’s one of the most recognizable helmets of all, and the inspiration for our MK5 Iron Man helmet.
Mark VI (Iron Man 2). Introduces the triangular arc reactor and features in the film’s final battle.
Iron Man 3 and the House Party Protocol
Mark VII (The Avengers, 2012). The armor that deploys around Tony as he falls from Stark Tower, and the suit he wears in the Battle of New York.
Mark 42 (Iron Man 3, 2013). A suit whose individual pieces fly to Tony and attach on their own. Its arm is one of the most iconic pieces of the film — and the basis for our wearable MK42 arm.
The House Party Protocol (Iron Man 3). In the film’s finale, Tony calls in his whole collection of armors at once. Among them is the Mark 17, nicknamed “Heartbreaker”, a favorite with fans and the suit behind our MK17 Heartbreaker helmet.
The Avengers Years: Mark 43 to Mark 47
Mark 43 (Avengers: Age of Ultron, 2015). Tony’s suit for the opening battle of Age of Ultron.
Mark 45 (Avengers: Age of Ultron). An updated suit with a sleeker look, used later in the film.
Mark 46 (Captain America: Civil War, 2016). The armor Tony wears in his conflict with Steve Rogers.
Mark 47 (Spider-Man: Homecoming, 2017). A remote-controlled suit Tony uses to keep an eye on Peter Parker.
Nanotech Armor: Mark 50 and Mark 85
Mark 50 (Avengers: Infinity War, 2018). A major leap: a nanotech suit that forms around Tony from a housing on his chest and can shape weapons on demand. Its helmet inspired our MK50 Iron Man helmet.
Mark 85 (Avengers: Endgame, 2019). Tony’s final armor, worn in the climactic battle of Endgame.
