Iron Man Armor: Mark II

"That's the coolest thing I've ever seen." "Not bad, huh?"

- James Rhodes and Tony Stark

The Mark II armor was Tony Stark's second Iron Man suit, heavily refining the bulky and rudimentary design of the previous Mark I suit, resulting in a far more articulated and sleek design.

It was described by James Rhodes as "an unarmed prototype of the Iron Man armor"

Creation
After returning from captivity in Afghanistan, Tony Stark began designing the Mark II armor, drastically revamping the design of the Mark I using resources and technology available to him through his company: Stark Industries. Tony started building this suit in stages, experimenting with new technology, mainly to improve the suit's flight capabilities. Working from his basement workshop Tony started by creating a pair of thruster boots, quickly followed by a pair of palm based repulsor gauntlets to stabilize his flight.

Once Tony had perfected the flight thrusters and repulsors he went on to create the armor of the suit itself, making it more sleek and aerodynamic than the Mark I, with articulated control flaps for added flight control and stability. He also created a user interface using his J.A.R.V.I.S. AI system. During his first control test, Tony decided to take the Mark II on its first full test flight despite J.A.R.V.I.S.'s recommendations. His flight proved to be an outstanding success until testing the suit's altitude limit, during which it demonstrated a near fatal icing problem in the higher altitude.

After this test flight Tony retired the Mark II suit, preferring to use the weapons integrated Mark III suit.

Theft
While dealing with palladium poisoning caused by his Arc Reactor and his impending death, Tony gave into his frustrations and got drunk during his birthday party, putting on his Mark IV armor and using it to show off in a reckless manner, endangering several of his party guests. Concerned over Stark's apparent irresponsibility and the safety of the those present, James Rhodes doned the Mark II suit and confronted Tony, erupting into a brawl that caused massive property damage to Stark's House and nearly injured several guests.

After their fight reaches a standoff, Tony and Rhodes fire their repulsors at one another, resulting in a repulsor explosion that destroys a large portion of Stark's house. Rhodes, left standing over a dazed Tony, then leaves with the Mark II armor which he flies to Edwards Air Force Base, turning it over to the United States Armed Forces under his supervision.

The US Armed Forces then proceeds to have the suit weaponized using guns and munitions provided by Justin Hammer, effectively transforming the Mark II into the War Machine: Mark I armor.

Later after the crisis at Stark Expo, the War Machine Mark I was re-converted back into the Mark II as Stark removed all Hammer tech added to the suit, considering it an insult.

When the Mandarin's forces attacked Tony's mansion the Mark II is destroyed when damage to the mansion's systems cause the suit to unintentionally detonate (possibly an overload of the miniture arc reactor).

Abilities
The Mark II armor was a complete revamp of the base principle and technology of the rudimentary Mark I armor, using improved resources and new technology that Stark developed specifically for the suit. The original bulky design was considerably streamlined, giving the Mark II a sleek, more human-like appearance. In addition to the more articulated design, this suit also integrated a new user interface system based on Stark's J.A.R.V.I.S. AI.

The Mark II carried over the enhanced physical capabilities of the Mark I suit and enhanced them considerably, now granting superhuman level strength, near bullet-proof durability, and enhanced movement speed and reflexes.

The greatest advancement for the Mark II armor was its vastly improved flight capabilities, now capable of sustained flight for long periods of time. This was made possible through Tony Stark's development of sustained flight thruster boots and hand based repulsor gauntlets for flight stability, all derived from and powered by his newly miniaturized arc reactor. The suit also possessed variable control surfaces for active flight control and maneuverability.

However, the Mark II appeared to lack any real form of weapons system, not yet possessing any of the Stark developed weapons that would later be integrated into future model suits. While its repulsors possessed an adequate amount of strength, they were developed solely for flight and not yet weapons grade.

It was discovered that the greatest weaknesses of the Mark II was its high altitude icing problem. Because the suit was still in the experimental stages it was not yet properly insulated. Thus, when it was exposed to the thin, cold air of the upper atmosphere, a sizable layer of ice would formed over its surface, immobilizing the suit and causing a complete system shut-down, proving nearly fatal for the user. Due to this the Mark II was retired to make room for the Mark III.
