Mark 42

The Mark XLII (Mark 42), known by its code name "Extremis" or the “Prodigal Son” is an Autonomous Prehensile Propulsion Suit Prototype was the forty second armor, as well as one of the many newly built suits, created by Tony Stark sometime after the events of The Avengers. It served as a prototype for Mark XLIII which could be found in Avengers : Age Of Ultron.

It was the armor featured in the movie Iron Man 3, and made its debut in the movie during the start, when Tony creates it in his basement, and tests the suit's functionalities. It was seen throughout the whole movie as Tony's main suit, and it was later destroyed by self-destruction when Tony ordered J.A.R.V.I.S. to do so, after remotely controlling it to trap Aldrich Killian within it to blow him up and finish him for good.

The suit is well known for its special ability to fly in separate pieces and wrap itself around Tony's body, piece by piece through 49 "state-of-the-art" computer chips that was implanted in his arms called "Micro-Repeaters", which enables him to communicate with his armor.

Armor Design
The Mark XLII has a unique and special design. Unlike most of its predecessors, the Mark XLII does not feature the usual Red and Gold plating, but instead has darker hue for the red plating and a lighter color for the golden plating.

Its appearance and design is reversed from the original design of the former armors. Whereas the areas with Red plating from its former armors are now covered with the gold ones and the same style goes with the Red plates of the armor.

Light Gold is the dominant color of this armor. It has a circular-shaped Unibeam with a white glow, and has a thinner appearance than a regular Iron Man Armor.

Prehensility
The Mark XLII has prehensile technology, allowing it to attach to Tony when controlled by his nervous system. The armor's ceramic and silicon infused plates allows it to retract and expand over the user's body. The user can also control what the armor latches onto (namely, another user).

Plasma-Penetration Unibeam
The Mark XLII's New Element Arc Reactor II and Plasma Projector made the Unibeam of this armor penetrable on any wall. This is the only suit to feature a penetrating Unibeam.

Tactical Weaponry
This armor is designed to be equipped with new Stark-based Technology. It offers a much more powerful version of weaponry than most of the other previous armors.

Remote Command
The Mark XLII also features the unique ability to control itself when Tony Stark isn't inside his suit or when Mark XLII is A.I-deactivated. The Subcutaneous Implants (also known as Micro-Repeaters) in Tony 's arms allow the armor to communicate with his nervous system helping the armor follow his commands. Any action done by Stark is imitated by Mark XLII if he connects with it. This also includes Remote armor control through combination of AR display headset with the Micro-Repeaters.

Self-Repair
The Mark XLII is capable of sustaining Self-Repair without using mechanical or electrical equipment through the use of an advanced Built-in Repair System which previous armors don't have. This is a unique feature in '''Iron Man 3 - The Official Game App. This feature is also showed in Iron Man 3 movie when tony plugs the suit up to a battery charger after crashing it to let it recharge and repair '''

Advanced Repulsion
The Mark XLII is upgraded with high-penetrating Repulsors that are much larger in cohesive size than most other armors. This is the reason why Tony Stark had solely relied on it in Iron Man 3 making it the noticeable capability of this armor.

Armor Separation Upgrade
The Mark XLII is capable of separating and folding into smaller Armor Plates if Tony Stark uses remote command through the Subcutaneous Chips implanted in his arms or if it is commanded by friendly Artificial Intelligence. The Mark XLII's armor separation derivative is highly enhanced to be intelligently controlled, reach the user on the longest distance possible or hit a target in more powerful, swift and accurate manners. This tactile function was derived from '''Mark XLI. '''Despite the upgrade stronger impacts forces armor pieces to separate. This problem was solved in Mark XLIII.

Water Resistance
The Mark XLII can also travel underwater like the Mark XXXVII because the armor is strong enough to withstand the crushing pressures deep under the ocean. It can also travel fast underwater. However, in Iron Man 3, the suit didn't seem water-resistant. This is because the armor was damaged, which allowed water to seep through.

Lightweight
Due the composite armor this suit is lighter than the usual Iron Man suit to help enhance its speed, agility, and prehensile systems. It is of lightest Iron Man armor, With the lightest armor being its predecessor, the Mark XLI Bones.

Donning System
The Mark XLII, 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 and exit the suit and automatically wrap or unwrap itself around him, anywhere at anytime, much like the other newly built Mark suits'. As well as be remotely called attach and unfold separate pieces around the user until complete suit is made

Armor
The suit is made from an advanced titanium alloy (providing high durability, hardness, compression and tensile strength), silicon infused-steel & ceramic composite armor a composition that can resist powerful attacks, including energy attacks, that can destroy normal materials.

It is based on the Mark XXIV and the Mark XXXVIII's armor, and might also be more durable and stronger than Mark XXXVIII. It also incorporates the Mark XXXIII's energy enhancement technology which projects a slight force-field that enhances the armor and improves durability greatly. This incredible durability might be based on earlier armors, like the ability to resist extreme heat, like the Mark XXIII, gamma radiation and electrical surges, like the Mark XXVI, bio-hazards, radioactivity (gamma and nuclear, like the Mark XXVIII) and chemicals, like the Mark XXXV and other potentially fatal conditions.

The suit has incredible damage resistance, thanks to the advanced Titanium alloy and its perforated steel-ceramic frame. The armor incorporates an adaptive pressure modification system which regulates internal strength, giving it underwater and sub-orbit capability. It is based on the Mark XXXIX which can travel to space which gives the Mark XLII the ability to go to space too. This is because the armor is strong enough to withstand cold temperatures, radiation and the low pressures in space.

It can travel far into space because of the technology of the Mark XX which makes it use less energy. It can also travel underwater like the Mark XXXVII because the armor is strong enough to withstand the crushing pressures deep under the ocean. It can also travel fast underwater.

The suit used a directed energy reactor, focusing its power and channeling it through to the suit's appendages and weapon systems, giving it enhanced speed, strength, and firepower. Because of the extra energy output, this armor also has a slight energy shield that passively improves its durability. This shield enhances its armor and greatly improves the durability.

The Mark XLII vividly features extremely powerful Electromagnetism. The much more powerful Electromagnets are the results of the armor's Enhanced Directed Energy Reactor, the feature first conceived on the Mark XXXIII. The Electromagnetic Gauntlets of Mark XLII are extremely enhanced. The single hand using an Electromagnetic Gauntlet can carry more than 12 people (with metallic objects such as name tags.) onto the Mark XLII. This is proven in Iron Man 3, wherein Tony Stark saves more than 10 people through the use of his Electromagnets. Such powerful electromagnets can be used as a ripping weapon.

Flight
The repulsors on its leg are stronger allowing it to travel into space. The armor also has an upgraded flight stabilizing system which enables the armor to have improved versatility during combat and precision during flight. but the suit is only a prototype so flight systems did not work 25% of the time. This suit can also fly at very high altitudes without ice building up, because (like all previous armors) it is also based on the Mark 3 which is the first armor to solve the icing problem.

Weaponry
Repulsors : Plasma-based Particles that fuse together to create directed energy Lasers. The Mark  Repulsors are ultimately enhanced through this technology. Being able to penetrate and cross through the thickest wall. This makes the Mark XLII’s repulsors the strongest out of any of its predecessors.

Unibeam : The armor has a very powerful plasma-penetration unibeam. Its unibeam was shown to be capable of killing Eric Savin (who has an enhanced healing factor thanks to his Extremis powers) with a point-blank blast through the chest. Notice that after the unibeam was fired through Savin’s chest, it went through the wall behind him and kept going.

Missiles : The armor is equipped with a very powerful missile on each forearm.

Flash Bang : This armor contained a detachable flash bang, but Tony gave it away.

Flares: The armor also contained numerous infrared flares, another feature common with its predecessors. The flares can be used as a weapon or as a distraction.

 Other Weapons : The Mark XLII 's weaponry systems can also be composed of the following, based from the fact that the Mark XLII 's armament was based on all the armors that precede it. Extra space allows the armor to carry much more weapons whilst not affecting the overall composition and performance of this armor. So with all these facts, the Mark XLII can be equipped with rockets, striker missiles, machine guns, grenades, fold-able cannons (possibly on the shoulder plate, like Iron Patriot), portable lasers, micro-repulsors (like that of the Comic Armors), shoulder-mounted guns (like that of Mark VI), repulsor-based weapons, electric fields, proton-based lightning charges, flamethrowers (maybe), sonic distruptors (like that of the Peacemaker), battle blades (like that of Silver Centurion), cryo blasters, Plasma-based laser projectors, tranquilizer rounds, syringe-like projectiles, crowd-control weapons, Unibeam Projection Systems, pulse bolts, elemental weapons, AA-based projectiles, frost charges, energy-concussive rays and other unknown weaponry that the Mark XLII can be possibly equipped with.

Before Iron Man 3
Tony Stark creates the prototype version of the prehensile technology system after testing the separate functional capabilities on the Mark XLI.

Iron Man 3
The Mark XLII is first seen when Tony Stark is testing it in his workshop. It is later used when Tony was seeing who was at his front door finding Maya Hansen. When the Mandarin attacks Tony's home, Tony controls the suit to wrap around Pepper until she made it safely out of the house. Tony then uses the suit to try to fend off the Mandarin's attack.

It was able to destroy two out of three helicopters but was heavily damaged. It fell down with his house but was able to make it out of the wreckage and away from Malibu. Tony finds out that the suit has flown all the way to Rose Hill, Tennessee. The suit is low on power and Tony has to find a way to charge it. He finds a garage to keep it where he meets Harley Keener. Before Tony Stark and Harley Keener left Harley Keener's Garage, Tony Stark took a Grappling Hook from the Mark XLII. Tony and Harley are able to charge the suit but not fully.

Tony later uses it to escape from Trevor Slattery's house and deal with his guards. Later, controlling the suit remotely, Tony kills Eric Savin and saves citizens falling out of Air Force One. It is hit by a truck and is knocked into pieces, but is somehow later put back together and arrives at the docks to aid the other suits in killing Killian, but hits a pole and falls into pieces. It is then used to trap Aldrich and self destructs on Tony's orders but since the suit is still in prototype and is extremely low on power and energy- it fails to kill him.

Spider-Man: Homecoming
Considering it was the "Prodigal Son", Stark reassembled the Mark XLII sometime later and kept it in Avengers Tower. As Stark was moving the Avengers stuff from the Avengers Tower to the New Avengers Facility, the Mark XLII was one of precious items on the Stark cargo plane. It is unknown what happened to the Suit after the plane crashed.

Iron Man 3 - The Official Game
In Iron Man 3 - The Official Game, it is the 2nd strongest armor in the Striker Missile category, and is the 8th strongest armor in the game, having a x7.0 Score Multiplier.

It is initially available for use in the start of the game, having a x1.0 Score Multiplier but then gets damaged after one short run of an instructional game to teach the player how to play, so the Mark III replaces the Mark XLII while it is being repaired.

Lego Marvel Superheroes
The Mark XLII is a playable armor in the game. This armor can get in the Level 5 - Rebooted Resuited, the other one being Mark I. To get this armor, it is located at the room where a big hologram head appears, this implies that could be J.A.R.V.I.S., then the player suddenly gets attack by Killian's armies. Outnumber them, when there's no one left, use the shield to the shield switchers, once there's two of them authorized. The lasers have been enabled, one of the lasers aim to one of the panels... (maybe) but one of them didn't, to fix this problem, aim the laser ray to the controller. Once solved, the Virus has been disabled, rebooting Jarvis' system, and then deactivates it.

After that, you need to go to the circle, and then the Mark XLII's pieces fly over, and they attach to Tony stark, replacing the Mark I, like upgrading however. The Mark XLII should be in the character collection once you complete Level 5.
