Iron Man Armor Mark I (Earth-6531)

"This is our ticket out of here."

- - Tony Stark to Ho Yinsen

The Mark I Armor was Tony Stark first Iron Man armor, built by him and Ho Yinsen to help them escape their captivity from the Ten Rings. The suit was created with limited resources around them, such as salvaged pieces of scrap metal and machine parts, unique being the only Iron Man suit not run by J.A.R.V.I.S. or any other computers.

Capabilities
The original Iron Man Armor, this suit serves as the basic template from which every Iron Man armor after it was built. The Mark I armor was constructed entirely from recycled Stark Industries machine and weapon parts, in addition to any of the other limited resources at Tony Stark to Ho Yinsen's disposal while held captive. Although not as advanced as future models, the armor is an extraordinary piece of technology put together in a dire situation, and is a longstanding testament to Stark's extraordinary intelligence. The armor greatly increased Stark's strength and durability, enabling him to overpower armed terrorists and survive an aerial impact with the ground after escaping. Multiple layers of durable metal salvaged from missile casings made the armor impervious to medium caliber firearms and reinforced its physical attacks. Because the armor only covered a majority of the vital areas to keep from becoming too cumbersome, Stark wore the thick pants, jacket, and gloves that he used while working with molten metal, underneath the armor as added protection and insulation against the heat from the suit's flamethrowers.

The suit was powered by a small electric motor that is partially exposed at the suit's lower back. The engine powered a pair of external, belt driven mechanisms in the suit's legs that helped support the vast weight of the metal suit. Similar mechanisms in the suit's arms and legs helped Stark to move around while wearing the armor and amplified the strength behind his movements, allowing him to throw punches that could destroy a heavy metal door, knock human enemies back several feet, and partially embedded his arm in a cave wall.

The armor's only weapons were a pair of flamethrowers mounted on each arm along with one single-shot missile concealed in the left arm. While not capable of sustained flight, the armor was capable of limited flight through single-fire rocket thrusters located on the back of each leg, enabling him to escape during the destruction of the Ten Rings Base.
