Iron Man has superhuman powers derived from incidents in which his armor was damaged, normally most notably when he was wedged in a pressure chamber. Many of the standard superhuman powers associated with Iron Man are as a result of these accidents. These include artificial intelligence and flight. The armor can also change the distribution of its body heat, allowing it to be impervious to extreme temperatures. The armor suffers harmful effects if worn for prolonged periods of time, and can only partially recharge its batteries for short periods; after it runs on batteries it is referred to as an \"EMP suit\".
The master armor was built by Howard Stark during the time of the original Iron Man. When Stark Industries went out of business, the armor was sold by Stark to Aldrich Killian, a socialite who later became the Agent Venom and was possessed by an alien parasite. It was then sold to the U.S. government and placed in a Category One underground super-hardened storage facility. In 1982, the U.S. government's Strategic Defense Initiative project, which attempted to produce an anti-missile system called Project Iron Man, lost funding and was shut down. The project's leaders sold the armor to Tony Stark for $2.99 million. Stark sold the armor to ORA for $12 million and had the proceeds donated to the Carter Center. The power source was later implanted within the armor, allowing Tony to use the armor as a power-source rather than an external source. The master armor's battery is powered by a special alloy that never degrades. It allows the armor to last indefinitely, and can store enough energy that a fully charged suit can fly up to 15 miles, fight enemies 5 times its own size, and hover for days. 7211a4ac4a
