Mark XXXI - Piston

The Mark XXXI (Mark 31), also known by its name as "Piston", is a Fully Loaded High-Velocity Centurion 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 the Iron Man 3, and made it's 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.

Armor Design
The Mark XXXI has teal and silver colored plates. Its face mask is colored white, and it uses one of the basic designs of the Iron Man suits, only it is more enhanced and lighter in structure. Its design is based almost completely on the Mark VIII, with only the helmet, color scheme, and capabilities of the armor being different.

High Speed
The Mark XXXI can fly at high speeds, and is faster than most of the Iron Man armors. Being the armor as the test prototype for its speed ability, it is the second to the fastest armor among all of Tony's armors, with the first going to the Mark XL.

The armor's speed can be estimated to reach around Mach 5 more or less. The Mark XIX precedes the armor's speed, therefore it being a prototype like suit for the even faster Mark XL.

Enhanced Energy Output
The Mark XXXI has an Enhanced Energy Output that allows it to transfer energy to the various repulsors in its system, including the Unibeam.

Thrusters
The Mark XXXI has powerful repulsor propelled thrusters equipped to its back.

Donning System
The Mark XXXI, 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 mechanics.

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 XLII's technology and the other newly built Mark suits'.

Repulsors
The Mark XXXI is equipped with standard repulsors technology enhanced to enable increased speed in flight.

Unibeam
The Mark XXXI has a standard circular-shaped Unibeam.

Missiles
The Mark XXXI is equipped with the same shoulder-mounted mini-missiles as the Mark VII. It also has a rocket on each arm.

Lasers
This armor is also equipped with the same lasers as the Mark VII.

Flares
This armor contained numerous infrared flares, another feature common with its predecessors.

The Iron Legion and Creation
TBAThe armor was created by Tony Stark with the Iron Legion Sometime after the events of the Avengers. He decided to make this armor faster than the prototype, the Mark XIX.

Completion and Storage
After completing the armor, Stark stored it in the Hall of Armors Extension beneath his Malibu House, where all the other previous Iron Man Armors he completed were stored in as well.

With Piston's completion, Stark proceeded to create the next armor, the Mark XXXII, also known as "Romeo".

Malibu Raid
When Tony's Malibu Mansion was raided, and later destroyed, the Mark XXXI along with the rest of the Iron Legion were still stored safely within the Hall of Armors Extension, as it was left undamaged during the attack. The chamber was still intact, completely sealed, and concealed from view.

This was part of Stark's plan, in which the Iron Legion was to be used later after he uncovered the truth behind the Mandarin and A.I.M.

Activation of the "House Party Protocol"
The Mark XXXI was activated by J.A.R.V.I.S. along with all the other armors in the basement of Tony's Malibu Mansion, under the order of the House Party Protocol given out by Tony. It then flew out of the Hall of Armors and went towards the Roxxon Oil Rig together with all the other 35 armors.

Arrival with the Iron Legion
When the Iron Legion arrived, the Mark XXXI surrounded the area with other other armors and waited for Tony's commands. When Tony ordered J.A.R.V.I.S. to "Target all Extremis heat signatures, disable with extreme prejudice", J.A.R.V.I.S.' responded with "Yes sir!", which echoed throughout all the suits, including the Mark XXXI.

Target Orders and First Strike
The Mark XXXI then started targeting the Extremis Soldiers in the area, and was the first armor to start attacking. It flew at a high speed and pushed one soldier off a column. It then landed on a platform, and blasted one soldier with it's Unibeam. After, the armor started fighting off three soldiers at once.

It was later seen being overwhelmed by the same amount of soldiers it started fighting. One soldier repeatedly punched the armor's chest piece, while another one ripped off the armor's head and right arm.Then the armor lost its Unibeam power. Severely damaged and overwhelmed, the armor flew off and brought the soldier that repeatedly punched it with it.

Overwhelmed and Destruction
Flying blind and at a high-speed, it crashed onto the base of the oil rig along with the Extremis soldier which destroyed the armor completely and killed the Extremis soldier that held onto it. Its crash caused a huge explosion that rocked the rig, and caused it to destabilize. Because of this, Tony requested J.A.R.V.I.S. to keep the rig steady using Igor, and the Mark XXXVIII went into action and held the Oil Rig steadily during the entirety of the battle.

Trivia

 * The Mark XXXI is the second to the fastest suit known among all of Tony's armors. The first being the Mark XL.


 * This suit was the first suit to attack the Extremis Soldiers in the film, and it was also the first suit to get destroyed by them, after it's head and left arm were ripped off, and then it crashed to the base of the oil rig.


 * Ironically, even if it is the last and strongest known armor available for use in Iron Man 3 - The Official Game, it is the first suit to get destroyed in the movie, after being ganged up by three Extremis Soldiers. On a side note, the Mark XXXI did manage to defeat 2 Extremis soldiers, making it tied for the most soldiers defeated on screen.


 * Although the original color design for the Mark XXXI was Teal and Silver, in Iron Man 3 - The Official Game, the color it has is Sea Green and Gold.
 * The Mark XXXI was the first and only armor to feature teal in its color scheme, making it fairly unique.
