Iron Man: Every Single MCU Armor, Ranked by Power

Iron Man Movie

As Tony Stark prepares to enter what is widely rumored to be his last adventure in the Marvel Cinematic Universe in April's Avengers: Endgame, the MCU superhero has built quite the extensive armory of suits to draw from in his long-awaited rematch with Thanos.

While Tony has reputedly built 42 Iron Man armors by the start of 2013's Iron Man 3, the genius industrialist is always tinkering and improving on his previous designs, constructing armors for specific purposes and threats. As such, below is a comprehensive ranking of every armor given a significant amount of screen time in the MCU from 2008's Iron Man to last year's Avengers: Infinity War.

20. MARK I

The first armor Tony Stark ever developed, the Mark 1 is understandably the weakest. Built from salvaged Stark Industries missiles and other repurposed ordinance in a cave deep in the mountains of Afghanistan, Tony and his friend Ho Yinsen constructed a miniaturized version of the arc reactor powering Stark Industries' headquarters in Southern California.

The slapdash reactor gave the crudely constructed suit just enough power to operate makeshift flamethrowers, hydraulic joints and even a small rocket launcher. With much of its machinery exposed, the suit was immobilized by heavy machine gun fire, forcing Tony to use an ejector function to barely escape his captors. The suit was later recovered by the Ten Rings and used by Obadiah Stane as the basis for his Iron Monger armor.

19. MARK II

The second suit Tony develops in the original film is more of a working prototype, eventually serving as the basis for both all his future designs and the foundation for James Rhodes' War Machine armor in Iron Man 2. More snugly fit and powered entirely by repulsor technology, the Mark II gives Tony the power of flight and the ability to reach supersonic speeds.

Unable to reach high altitudes without freezing in the atmosphere, Tony would decide to use different metal alloys for future incarnations of the armor.

18. MARK III

The third and final Iron Man armor built by Tony in the original film, and the first in the MCU to feature the classic color scheme, Tony uses a gold-titanium alloy to solve the freezing problem while painting it "hot rod red" to give it a little more flashy personality. The first armor to be deployed tactically, Tony outfits the armor with an extensive weapons array, includeing a wrist-mounted rocket launcher, powerful repulsor blasts from its gauntlets, shoulder-mounted targeted guns, flares in its legs and a powerful unibeam firing directly from the arc reactor.

While able to withstand a direct hit from a tank, the suit is not completely bulletproof as evidenced by bullet holes in the torso after an incursion into Afghanistan. Following Tony's battle with the Iron Monger at the end of the film, the suit is eventually replaced.

17. MARK V

Iron Man MK V Iron Man 2

Designed as a portable suit of armor in case he was ever caught unawares away from his main Iron Man suit, Tony created a compact armor disguised as a seemingly innocuous briefcase. While not as capable or protective as the normal suit, as seen with its scaled design and difficulty subduing Whiplash, the suit is capable of armoring Tony without the need for an extensive assembly rig.

The suit makes its debut during the Formula 1 race in Monaco during Iron Man 2, entrusted in Happy Hogan's care until Tony is ambushed by Whiplash. Sporting a color scheme similar to Iron Man's '80s Silver Centurion armor, the briefcase design is also a nod to how Tony would transport his armor on the go in the comics during the same period.

16. MARK IV

The final Iron Man armor to use a palladium core after Tony discovered a new element to power the arc reactor without the toxic blood poisoning the original core caused, the Mark IV is Tony's main suit for the majority of Iron Man 2. Featuring a slightly bulkier design than its predecessors, the suit gives Tony more protection than previous versions of the armor.

The suit is first unveiled during Tony's grand entrance at the launch of the Stark Expo before being worn by an intoxicated Tony at his birthday party in Malibu. Following a confrontation with Rhodey, the armor and its toxic core are retired for good.
