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

The Mark 26 (Mark XXVI), also known by its codename as "Gamma", is a Gamma Radiation 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 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.

The suit earned it's name "Gamma", for being able to withstand extreme heat and temperatures as well as very powerful and devastating electrical surges. It's specially built armor is also known to make it withstand gamma radiation, and this is where it's name is derived from. It was built for heavier construction and was based out of the Mark 25's design. It can also be used in dangerous situations.

Armor DesignEdit

This armor's design is almost an exact copy of the Mark 25's design. It's body armor, as well as it's unique jack-hammer like arms feature, is almost identical to the Mark 25's. With only the exception of the recolored platings, and the upper-middle portion of the face mask, widened approximately by an inch.

The armor also has a very unique feature that cannot be found in previous armors, and just like the Mark 25, has a different colored Arc Reactor, which is a glowing White, and this also goes for it's eye color as well.

It's color scheme is dark green and black with some silver platings in a few areas. The dark green colors are located in various platings on the armor. One is on both of it's jackhammer-like arms screwed-like platings. Another upper-middle portion of it's helmet, and the rest are on various areas in it's body armor and it's leg platings.

The black and silver colors cover up most of the armor on the areas where mostly it's defense systems lies, as well as very important or special components, which includes all the armors limb joints, and openings.

Armor CapabilitiesEdit

Intense Strength Edit

Using the armor's powerful Pneumatic Hammers, the Mark 26 is able to create intense power within it's Hammers to be able to crush hard objects or debris.

Gamma Resistance Edit

The Mark 26 can resist gamma radiation, which is where its name is derived from. It can also resist extreme heat and temperatures, as well as powerful and devastating electrical surges.

Armor FeaturesEdit

Enhanced Pneumatic HammersEdit

The Mark 26 has two Pneumatic Hammers, with a single Hammer attached to each arm. The Hammers are presumed to be an improved version of the Mark 25's Pneumatic Hammers; Since the Mark 26 is an Upgrade of the Mark 25.

The Hammer's functionality works the same as it's predecessor, and is similar to the way a jackhammer works. The Hammer can crush very hard objects or debris with sheer force and power and can be lethal to enemies as well when used as a weapon.

Donning System Edit

The Mark 26, 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 26 has standard based Repulsor technology.


The Mark 26 has a thin, vertical rectangular-shaped Unibeam powered by the new Vibranium Arc Reactor Mark II.

Pneumatic HammersEdit

The Mark 26 has two Pneumatic Hammers, with one on equipped on each arm. Although not considered a weapon, they can still be lethal when used.


Before Iron Man 3Edit

Creation and the Iron LegionEdit

Sometime after the Battle of New York, Tony, who was haunted by what happened in New York, got obsessed in making more Iron Man suits. One of them was the Mark 26. He built the Mark 26 as an upgrade to the Mark 25.

Completion and Storage Edit

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

With Striker's completion, Stark proceeded to work his next armor, which resulted in the creation of the Mark 27 / Disco.

Iron Man 3Edit

Malibu RaidEdit

When Tony's Malibu Mansion was raided, and later destroyed, the Mark 26 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"Edit

The Mark 26 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 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.

Arrival with the Iron LegionEdit

When the Iron Legion arrived at the scene, the Mark 26 followed the other armors as they surrounded the area. Awaiting Tony's orders, the Mark 26 could be briefly seen hovering in the background with the other armors as the Extremis Soliders stand surprised with the arrival of the Iron Legion.

When Tony gives J.A.R.V.I.S. the order to "Target all Extremis heat signatures. Disable with extreme prejudice.", J.A.R.V.I.S. replies with "Yes sir!", which echoes throughout all the armors, including the Mark 26.

The armor then starts targeting and attacking the Extremis Soldiers in the are, and fights them off with the help of the other armors during the ongoing battle. 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. The Mark 26 then resumes to flying around the oil rig in the aftermath of the battle.

"Clean Slate Protocol" Edit

The Mark 26 was then detonated by J.A.R.V.I.S. for fireworks along with the other 20 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 one of the last suits to detonate.
