5 Strongest Iron Man Suits in the MCU, Ranked by Power

Over the course of his role in the Marvel Cinematic Universe‘s Infinity Saga, Iron Man proved to be one of the franchise’s most important characters. As the first hero introduced into the franchise, it’s only natural that Iron Man grew into one of its central figures in subsequent movies. A founding Avenger and a leader of the franchise’s heroes, Iron Man’s MCU story saw Tony Stark perform many impressive feats, holding his own in battle even against villains and superpowered beings far stronger than himself. All of this was made possible by his creation of high-tech Iron Man armor, with Stark constantly upgrading and updating his equipment throughout his MCU tenure.

With the character serving as such a consistently important figure in the MCU’s Infinity Saga, he wore many different suits during his stint in the franchise. The best MCU Iron Man armors are often those considered the coolest or best-looking, but in terms of raw power and function, the following are the best the franchise has to offer. It’s worth noting that there are many Iron Man suits whose capabilities aren’t fully shown, but based on what we’ve seen in the MCU so far, these are the most powerful.

5) Mark XLV

Iron Man’s Mark XLV armor is the suit he wears in Avengers: Age of Ultron, best shown during the Battle of Sokovia. While it’s far from the most high-tech suit Tony Stark wears in the MCU, its combat capabilities are pretty well-represented in the movie. It’s able to fire a unibeam that damages the vibranium-laced Ultron, and also stands up to considerable punishment during the battle. It’s not the most advanced, but it’s still powerful enough to hold up against an incredibly dangerous villain.

4) Mark XLVI

The armor worn by Iron Man during Captain America: Civil War, the Mark XLVI, might not seem at a glance to be exceptionally powerful, but the evidence establishes it as one of the hero’s best suits. This MCU Iron Man armor is worn in battle against multiple other heroes, and is later shown to allow Tony Stark to hold his own in battle against the combined might of both Steve Rogers and Bucky Barnes. Considering that the Mark XLVI proves equal to the power of two super soldiers, as well as the heroes of Team Cap, it’s a pretty powerful suit.

3) Hulkbuster

One of the most obvious upgrades to Iron Man armor in the MCU is the Hulkbuster suit, which is shown in Avengers: Age of Ultron. Employed by Iron Man to match the strength of Savage Hulk, the Hulkbuster suit is perhaps the most impressive-looking armor worn by Tony Stark in the MCU. It’s also later used by Bruce Banner to battle Thanos and his forces, further proving its impressive strength. However, while its bulk is impressive, it restricts movement and agility in a way that some other MCU Iron Man suits do not.

2) Mark L

The Mark L is easily one of the coolest Iron Man armors in the MCU. Worn during the events of Avengers: Infinity War, it’s a suit that boasts some incredibly impressive features, keeping Iron Man alive in space, and seeing him match Thanos hand-to-hand for a short while, even with the Mad Titan wielding multiple Infinity Stones. It might not be the most powerful suit of armor worn by Tony Stark in the MCU, but it’s undeniably up there as one of his best.

1) Mark LXXXV

The Mark LXXXV is the suit worn by Iron Man during the events of Avengers: Endgame. The improvement on the Mark L comes by way of five years’ worth of upgrades, and while only a few additional features are clearly shown, the nanotech armor comes with the ability to house and wield all six Infinity Stones. This alone makes it by far the most powerful Iron Man armor in the MCU, as well as being the most iconic being that it’s worn during Tony Stark’s heroic ending.
