- "Deep Sea Diving Suit designed for extreme pressure and traveling at high-speeds underwater. Features upgraded work-lights for high visibility."
- ―(Iron Man 3 - JARVIS: A Second Screen Experience) The Mark 37's description in the JARVIS Application.
The Mark 37 (Mark XXXVII), also known by its codename as "Hammerhead", is a Deep Sea Suit, and was one of several new Iron Man Armors created by Tony Stark as part of the Iron Legion. The armor was created sometime after the Battle of New York.
It was featured in Iron Man 3, and made its debut when Tony ordered J.A.R.V.I.S. to initiate the "House Party Protocol", in which it was activated along with all the other suits to aid Tony in his battle against Aldrich Killian.
The suit earned its name the "Hammerhead", for being to able to travel undersea and fully submerge itself without its system short circuiting and eventually malfunctioning. It was built for traveling deep underwater and has a thick reinforced armor specially built for the crushing pressure of subaqueous journeys.
The Mark 37 has dark sea green and golden colored plates in it's design. This is the first and only armor to feature sea green in its color scheme, making it fairly unique. It's body armor re-uses and perfects the original design used in the Mark X, having a circular and triangular shape in the chest piece, surrounding the Unibeam. It is equipped with visible and powerful extra repulsors, attached to the sides of the suit, in the abdomen area, that were meant to increase flight speed and power.
Just like the Mark VI, the Mark 37 has the unique ability to travel underwater without allowing water to seep in through the armor. The armor has water resistant plating that blocks the passage of water, and is sealed tightly to fully prevent water from getting into the armor's systems and affecting the person using the armor.
The armor has various features. They include headlights, a hydrogen converter, an advanced donning system, infrared scanners, and a pressurized system.
As seen in Iron Man 3, the Mark 37 has infrared scanners. It used these scanners when it was targeting the Extremis soldiers. This is the first armor to feature infrared scanners.
The Mark 37, along with all the other newly built Mark suits, uses a more advanced technology that was based off on the Mark VII's technology, which is able to wrap itself around Tony's body, without the aid of robotic arms or any external mechanicals.
It can flexibly open itself to allow Tony to enter into the suit and automatically wrap itself around him, anywhere at anytime, much like the Mark 42's technology and the other newly built Mark suits'.
The Mark 37 has standard based Repulsors.
The Mark 37 has a standard circular-shaped Unibeam powered by the new Vibranium Arc Reactor Mark II.
Since the armor was built to go on underwater journeys, the Mark 37 contains Torpedoes for use when on underwater missions. This is also the first and only armor to be equipped with torpedoes.
The Mark 37 has an Electric Field equipped into it's system. One of it's primary weapons, it uses it only when it is under water being attacked by enemies. Although mentioned, it is unknown where this weapon is located.
Before Iron Man 3
Iron Legion and Creation
Sometime after the Battle of New York, Tony Stark, who was haunted by his near death experience from the invasion, suffered from post traumatic stress disorder, becoming paranoid and obsessed with security.
Because of this, Stark began working on the Iron Legion, and overtime, created several Iron Man Armors, from the Mark 8 to the Mark 36, all built with various designs and purposes. After the Mark 36 / Peacemaker's completion, Stark proceeded to working on his next armor with the ability to travel underwater at high speeds, the Mark 37.
Completion and Storage
With Hammerhead's completion, Stark proceeded to work on a new type of suit with increased strength and power, and built to lift heavy objects, the Mark 38 / Igor.
The Mark 37 was still stored in the Hall of Armors inside Tony's Malibu Mansion, even after the Mandarin's attack, it was still safe in the Hall of Armors underground extension, wherein Tony kept all the other suits he created inside.
Activation of the "House Party Protocol"
When Tony and Rhodey head towards the Roxxon Oil Station, Tony orders J.A.R.V.I.S. to initiate the "House Party Protocol", which activates all the suits in the Hall of Armors, including the Mark 37.
After Tony and Rhodey are surrounded by Extremis Soldiers, a little light in the sky appears, marking the arrival of the Iron Legion'. The Mark 17 is the first to arrive at the scene followed the other suits, and then the Mark 37. It flew next to the Mark 30.
Just after the suits surround the station in the form a large circle, the Mark 37, controlled through J.A.R.V.I.S., follows Tony's orders to "Disable all Extremis Heat signatures with extreme prejudice.", and then it locks it's targets on the Extremis Soldiers, and ensues to eliminate whatever it targeted.
The armor was presumed to have fought and killed several extremis soldiers during the fight, as it was one of the last 21 armors left standing and succeeded in eliminating the remaining extremis forces with the help of the other Iron Legion armors. Hammerhead then resumes to flying around the oil rig in the aftermath of the battle.
"Clean Slate Protocol"
The Mark 37 was then detonated by J.A.R.V.I.S. for fireworks along with the other 21 armors, under the Tony's order of the "Clean Slate Protocol". This was to show Tony's devotion to his girlfriend, Pepper Potts. It was the 15th suit to detonate.
The Mark 37 is one of the armors available for purchase during the first version of the game. It is categorized under the Frost Charge special power section. The Mark 37 is the 4th strongest armor with the Frost Charge Special Power and it is also the 13th strongest armor in the game.
