Tony Stark: "You're right, we do need back up."
Rhodey: "Yeah, a bunch."
―Tony and Rhodey talking about the "House Party Protocol" suits, while waiting for them to show up.

The Mark XXII (Mark 22), also known by its name as "Hotrod", is a War Machine 2.0 Prototype 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.[1]

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 the rest of the Iron Legion to aid Tony in his battle against Aldrich Killian.

The was named "Hotrod" for it's similar color design, and resemblance to Stark's Hotrod Car featuring a unique custom flame design on the armors gauntlets' and boots' plates.

Hotrod was made to have the same protection as the first War Machine armor, but with 1/3 of the weight.

Armor Design

This suit was a non-weaponized prototype of the War Machine Mark II armor. However, it did have the signature repulsors and a micro-cannons on each of its gauntlets. It featured dark plating on the torso and helmet, but sported crimson and orange flames on the appendages. 

Armor Capabilities


Succeeding its predecessor in a lot of aspects, the armor has very high versatility. Lighter in weight than the Original War Machine Armor, the Mark XXII can do various abilities that the previous armor could not. Able to dodge objects, fly faster and move swifter; its versatility is its only special capability, while the rest of its features use the same design and technology from the new advanced suits of the Iron Legion.

Armor Features


The Mark XXII has powerful repulsor-propelled thrusters on its back. This armor features the latest thruster design.

Donning System

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



The Mark XXII has standard based Repulsor technology.


The Mark XXII has a horizontal rectangular shaped Unibeam, with a bright whitish blue glowing light from the Vibranium Arc Reactor Mark II core it is powered from.


This armor is equipped with a belt fed micro-cannon (Presumably 20mm caliber) on each of its gauntlets.


Before Iron Man 3

The Iron Legion and Creation

Sometime after the Battle of New York, Tony Stark, who was haunted by his near death experience from the event, suffered from post traumatic stress disorder, became paranoid and obsessed with security.

Because of this, Stark began working on the Iron Legion, and through its development, created several Iron Man Armors, from the Mark VIII to the Mark XXII, all built with various designs and purposes. After the Mark XXI's completion, Stark wanted to create a new armor for his best friend James Rhodes, and began working on the prototype, the Mark XXII.

It was presumed that the armor was tested a number of times before it was fully functional and ready for combat.

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 Sneaky's completion, Stark proceeded to create a new type of suit with special anti-heat features, the Mark XXIII, also known as "Shades".

Iron Man 3

Malibu Raid

When Tony's Malibu Mansion was raided, and later destroyed, the Mark XXII along with the rest of the Iron Legion were still stored safely within the Hall of Armors Chamber, 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 XXII was activated by J.A.R.V.I.S. in the basement of Tony's Malibu Mansion, under the order of the House Party Protocol issued by Tony. It then flew out of the Hall of Armors and went towards the Roxxon Oil Rig, together with the other 35 armors.

When the Iron Legion arrived, the Mark XXII followed flew beside the other armors as they slowly surrounded the area. While waiting for Tony's orders, the Mark XXII can be seen hovering in the background with the other armors, as the Extremis Soldiers stand surprised with the arrival of Iron Legion.

After, Tony orders JARVIS to "Target all Extremis heat signatures. Disable with extreme prejudice.", which JARVIS replies to with "Yes sir!", which echoes out through all of the suits, including the Mark XXII.

The Mark XXII destroyed and anchored to a metal pole.

The armor then started targeting and attacking the Extremis Soldiers in the rig, and fights them off with the help of the other armors during the ongoing battle. In the midst of the battle, it can be briefly see blasting and fighting soldiers on the backgroune. The armor is later controlled by JARVIS to aid Tony in his rescue for Pepper.

Failed Attempt and Destruction

The suit flew up to the platform of Tony's location, and just as Tony was about to jump into the suit, an Extremis Soldier vaulted a yellow metal pole from one of the oil rig's rails, straight through it. Thus destroying it as it was nailed on one of the base stands of the oil rig, while many parts of the suit broke off.
