( list ) iron man suits [ for personal reference ]
Mark I: As in the comics, the first armor which Stark builds with Yinsen's help while in captivity in Afghanistan during the first film is crude and bulky. It had the ability to amplify Stark's strength tremendously and protected him from small arms fire. The suit was armed with flamethrowers and a missile launcher, as well as a limited rocket jump capacity to allow Stark to exit the immediate hostile area after he sustained damage to the suit's knee joints during his escape. The suit was also able to protect the occupant from the effects of extreme g-forces. However, the rockets failed shortly after the start and the suit shattering upon landing and forced Stark to abandon it to attempt to reach friendly territory. Later, Stark's enemies found the abandoned armor, using it as the base design for Obadiah Stane's Iron Monger suit (although Stane still needed to steal the power supply from Stark). The second film shows that Stark displays the Mark I within his workshop, with the label "Reconstruction", and has it apparently retrofitted with an independent arc power source, allowing it to be operated by other users that have access to Stark's lab.
Mark II: Upon returning home during the first film, Stark developed the sleeker, polished stainless steel Mark II prototype version with improved flight capability. Furthermore, the Mark II was the first one to have a holographic HUD, repulsor technology and to operate with remote assistance from JARVIS, who manages the armor's systems at Stark's command and also have variable control surfaces for active flight control by JARVIS to automatically stabilize the suit in flight. Like the Mark I, the Mark II was able to protect the occupant from the effects of extreme g-forces. However, it was prone to icing at high altitudes, which would cause it to stall. The Mark II was then replaced with the Mark III's Gold/Titanium Alloy to correct these problems. However, Rhodes briefly contemplated using it. The second film shows that Stark displays the Mark II prototype within his workshop, with the label "Prototype", and has it retrofitted with an independent arc power source as shown when it was operated by James Rhodes in hand-to-hand combat against Stark in the Mark IV armor.
Mark III: The armed red/gold Mark III prototype armor was the last armor built in the first film and was built with a gold-titanium alloy to resolve the freezing problem. Like the Mark II, the Mark III has a holographic HUD and to operate with remote assistance from JARVIS manage the armor's systems at Stark's command and also have variable control surfaces for active flight control by JARVIS to automatically stabilize the suit in flight. Like the Mark I and II, the Mark III was able to protect the occupant from the effects of extreme g-forces. It was able to withstand small arms fire, an explosion from a tank shell (the shell exploded in close proximity to Stark, resulting in a fall from several thousand feet up), followed by hits by 20mm Vulcan shells and a high speed collision with an F-22 Raptor with only minimal cosmetic damage. In addition to repulsors, it was armed with anti-tank missiles on the wrists, anti-personal guns on the shoulders that could pick out individual targets, and flare launchers on the hips. When Stark reverted to the original reactor after the second reactor was stolen by Stane to power the Iron Monger suit, the first reactor had great difficulty providing enough power to the Mark III suit, being depleted to around a fifth of its power supply simply by flying Stark from his home to Stark Industries, with the last 20% being exhausted and was extremely damaged in the fight against Stane in the Iron Monger armor. The second film shows that Stark displays the Mark III prototype within his workshop, with the label "Battle Damaged". The Mark III armor's look was inspired by the signature red-and-gold armors in the comics.
Mark IV: The Mark IV armor is the first shown armor in the second film. The suit has a differently-colored HUD. Although its full arsenal and fighting potential is not explored in the movie. When it was shown on display within Stark's workshop, the Mark IV was labeled "Awaiting Upgrades" above it.
Mark V: Also introduced in the second film is the Mark V travel armor, a portable suit developed for emergency use that is lightweight and flexible enough to take the form of a briefcase that's handcuffed to Happy Hogan. The armor is deployed as Stark is forced into a confrontation with Ivan Vanko in Monaco. By kicking open the case, inserting his hands into the protruding gloves and placing the main assembly onto his chest, the armor folds out around Stark, quickly forming into a full red-and-silver armor. This armor is shown to be durable enough to withstand the focused repulsor energy of Vanko's energy whip attacks, though it sustained heavy internal and external damage. While this model features the palm-mounted repulsors, any potential flight capability is not shown (while in the game based on the second movie it is established that the suit can fly, but it takes all of its power just to keep Tony airborne, preventing him from carrying anything else). Because of how form-fitting the the suitcase suit was required to be, the production team researched some of the classic comics armors, since they were seen as essentially variations on muscle suits. One specific aspect of an earlier armor was the color scheme from the Silver Centurion armor.
War Machine: After Rhodes confiscates the Mark II armor on behalf of the United States government in the second film, it is heavily weaponized by the United States Air Force for their "War Machine" project. The Mark II's ballistic weaponry upgrades were provided by defense contractor Justin Hammer. Two weapon pods containing a 9mm submachine gun and a 5.56 mm assault rifle, respectively, are mounted on both forearms. An external 7.62mm minigun is attached via a gyro-stabilized arm mounted behind the right shoulder. Enclosed inside of the left shoulder is a 40 mm grenade launcher capable of firing heavy munitions, including a bunker-buster warhead (which Hammer personally nicknamed the "Ex-Wife") which performed well below expectations when it was used against Vanko's suit, completely failing to explode. The energy repulsors from the original design are still located in the palms and chest. Though Rhodes is the War Machine suit's primary pilot, its internal computer systems were linked to the Hammer Industries mainframe, allowing it to be operated by remote.
Mark VI: The Mark VI armor differs little from the Mark III and Mark IV platform; the main difference being a triangular-shaped chestplate protecting the arc reactor assembly. The major changes are to the shoulders and legs, and convey a more linear appearance. The suit was also designed for the greater amount of fist fighting on the ground seen in the movie. The new model was shown using two weapons not show in previous models: a multi-fire adhesive grenade launcher in the upper arm, and a one-time-use hand-mounted laser weapon, powerful enough to cut through several Hammer Drones cleanly in half. The armor retains the red and gold color scheme.
Any additions beyond this point are suits made in games or any potential new ones that are made in the 2012 film version of The Avengers. Note that this is all copied from wikipedia and that unless a note is in bold and in brackets, it was there when i copied it.
