Iron Man Suits
These are the main Iron Man suits in the MCU
Mark I
The Mark I (Mark 1), was the first Iron Man suit built and created by Tony Stark. It was built in the initial events of the live-action film, Iron Man. The suit was later used as a model for Obadiah Stane's Iron Monger.
It was featured in the movie Iron Man, and first appeared when Tony and Ho Yinsen were held captive by the terrorist group known as the Ten Rings. While they were held captive, Tony and Yinsen devised a plan. In the cave, they created blueprints for the Mark I.
The suit was very crude, due to the limited tools and resources that were available. Its successor was the Mark II, built inside the Stark Mansion.
The suit has several notable functionalities and weapons. It is equipped with a Manually Deployed Rocket Launcher, a Flamethrower mounted on each arm, Jet Boots equipped in its soles, an exposed Internal System attached to its back, and the very first Miniature Arc Reactor. The reactor powers the entire suit. Later, Tony created an upgraded version that would power almost every other suit to date.
Mark II
The Mark II (Mark 2), was the second Iron Man Armor designed and created by Tony Stark and is the successor to the original Mark I armor.
It was constructed as a prototype with an emphasis on exploring flight potential. As the first suit of Iron Man Armor built at Stark Industries, the Mark II armor features various new technology and weapons. It was soon replaced by the Mark III armor after it's initial flight testing revealed it's inability to reach the higher atmosphere due to the build up of ice.
Mark III
The Mark III (Mark 3) was the third Iron Man Armor designed and created by Tony Stark and is the successor to the Mark II. The armor was designed with upgraded technology and improved features to surpass its predecessor's capabilities. It's also the classic armor.
The strongest of the armors in Iron Man, it was designed for customization. The Mark III was equipped with a variety of incredible enhancements and upgrades. It was heavily damaged at the end of the first Iron Man by the Iron Monger. It was later succeeded by the Mark IV.
Even though it was not used in Iron Man 2 it was put in the Hall of Armors with the original 7 armors. Also, the suit has flares and strong repulsors, along with more tank missiles. The Mark III appears in Iron Man 3 along with other 6 armors in Tony's garage, and also after where it is destroyed when a terrorist attack occurs in Tony Stark's Malibu Mansion.
Mark IV
The Mark IV (Mark 4) was the fourth Iron Man Armor designed and created by Tony Stark as the successor to older Mark III model.[1]
The armor differs only slightly from it's predecessor, with only cosmetic changes to the armor plating, and a few changes in the capabilities of the armor itself.
The Mark IV was featured in Iron Man 2 along with the Mark V, Mark VI, and the War Machine Armor Mark I.
Mark V
The Mark V (Mark 5), also known by it's names as the "Football" and Suitcase Armor, is an Emergency Suit, and was the fifth Iron Man Armor designed and created by Tony Stark. It is the first armor to feature a new portable system that can fold itself into a briefcase and be deployed for use in civilian areas.[1]
It was built sometime between the events of Stark's Revelation as Iron Man and the Opening of the Stark Expo. The armor was featured in Iron Man 2, during Stark's battle against Ivan Vanko at the Grand Monaco Racing Track.
The suit was built as a base for experimenting on newer and more advanced transport features for Tony's suits, so as he would be able to don them faster than before. It specializes in smoother transport, and it is collapsed into a suitcase and can be deployed anywhere, allowing Tony access to the suit especially in a civilian environment.
Mark VI
The Mark VI (Mark 6), is an All-Purpose Suit, and was the sixth suit built and created by Tony Stark, after he found the solution to the Palladium core's poisoning, which was the newly improved Arc Reactor, in the movie Iron Man 2.
Mark VIII
The Mark 7 (Mark VII), is a Fully-Loaded Rapid Deployment Suit, and was the seventh suit created by Tony Stark , to surpass the Mark VI, sometime between the events of Iron Man 2 and The Avengers.
It was featured in The Avengers movie, and made it's debut in the movie when Tony was forced to order J.A.R.V.I.S., to get it ready for combat, despite it still being constructed, to use it in the upcoming battle with the Chitauri Army, as the Mark VI was heavily damaged from its last use by Tony during the events in the S.H.I.E.L.D. Helicarrier.
The suit was built for heavy-combat, and is suitable for prewar involved situations, as it was war-ready, and was heavily armed with weapons, which it was specially created for.
The armor has a unique feature that involves forming itself into a large red pod, and when opened, has mechanical arms, that can extend and reach into Tony's arms, grabbing them and slowly wrapping itself around him.
This is done through the use of two special metallic bracelets, both of which have encrypted codes embedded within them in the black rectangular spaces. The laser scanners on the mechanical arms scan these to confirm the user's identity and activate the pod's functionality. The armor then forms itself around Tony and becomes visible as the Mark VII armor.
Mark LXXIII
The Mark 42 (XLII), also known as the Autonomous Prehensile Propulsion Suit was the forty second armor, as well as one of the many newly built suits, created by Tony Stark sometime after the events of The Avengers.
It was the armor featured in the movie Iron Man 3, and made its debut in the movie during the start, when Tony creates it in his basement, and tests the suit's functionalities. It was seen throughout the whole movie as Tony's main suit, and it was later destroyed by self-destruction when Tony ordered J.A.R.V.I.S. to do so, after mentally controlling it to trap Aldrich Killian within it to blow him up and finish him for good.
The suit is well known for its special ability to fly in separate pieces and wrap itself around Tony's body, piece by piece through a "state-of-the-art" computer chip that was implanted in his forearms, which enables him to mentally communicate with his armor.
