Fictional character biography
Anthony Edward "Tony" Stark was born on Long Island, New York. As a child, he inherited his family's business, Stark Industries, when his parents were killed in a car crash. Developing equipment for the U.S. military, he travels to a war zone to conduct a weapons test when he triggers a booby trap. His heart is critically injured by shrapnel, and he is captured by the communist Wong-Chu, who demands Stark build him a weapon. Stark instead builds a suit of armor that sustains his heart, becoming Iron Man. The war zone Stark visited was changed retroactively multiple times by different writers to correspond with the character's age, which is explained by a "sliding scale of continuity" in which the timing of significant events in the world of Marvel may change. This conflict was the Vietnam War for the first decades of Iron Man's publication history. This was changed to an unnamed Southeast Asian country in the 1990s, and a conflict in the fictional country Siancong was ultimately created to justify the inconsistency.
Iron Man returns to the United States and becomes a superhero, convincing the public Iron Man is Stark's bodyguard. When he is called to stop the Hulk and learns Loki is behind the Hulk's attack, he joins forces with the Hulk, Thor, Ant-Man, and the Wasp to defeat Loki, and they agree to form a superhero team, the Avengers. He also helps found the intelligence agency S.H.I.E.L.D., providing the organization with equipment. Iron Man then undergoes surgery to replace the damaged portions of his heart, eliminating the need for his prosthetic chest plate. As he comes to regret his involvement in weapons manufacturing, Stark Industries is changed to Stark International, an electronics company that emphasizes environmentalism and ending world hunger. S.H.I.E.L.D. attempts to take over the business and return it to weapons manufacturing. At the same time, Iron Man is framed for murder. These stresses cause him to begin drinking, and he develops alcoholism. Though he gets sober, he relapses because of a plot orchestrated by his business rival Obadiah Stane. Iron Man briefly loses his company to Stane, passes the Iron Man mantle to his ally James Rhodes, and becomes homeless. After Stark recovers, Stane adopts an armored suit and becomes the Iron Monger before being defeated. Iron Man then founds a space technology company, Stark Enterprises. When Iron Man learns Justin Hammer had acquired the Iron Man armor's technology, he seeks out all the other armors. The resulting fights leave Iron Man a fugitive, leading him to fake his death and then describe himself as a new Iron Man.
When Iron Man is shot in the spine and paralyzed, he develops a new prosthesis that grants him mobility. This prosthesis is hacked and controlled remotely, causing neurological damage that appears for a time to kill him. Rhodes temporarily becomes Stark's chosen successor as Iron Man. After returning, Immortus places Stark under his control and turns him evil. The Avengers bring an alternate Tony Stark from another reality to help defeat him. Iron Man is killed and the alternate Tony Stark becomes the new Iron Man, but Franklin Richards merges both versions into a single being when he rewrites reality. Stark's company is bought out at this point, so he starts a consulting firm, Stark Solutions. His secret identity is revealed to the public shortly afterwards. He is then appointed Secretary of Defense until the Scarlet Witch alters his mind, causing him to behave drunkenly at the United Nations and leave in disgrace. When Mallen becomes a threat through the Extremis project, Iron Man has Maya Hansen inject him with the Extremis virus, giving him a biological armor he can control with his mind.
Iron Man serves as the Superhero Registration Act's enforcer upon its enactment, creating a schism between superheroes, with Iron Man leading proponents of registration against a group of resistors led by Captain America. After the conflict, Iron Man becomes head of S.H.I.E.L.D. The government dismantles S.H.I.E.L.D. after it fails to prevent an alien invasion, but Iron Man refuses to turn over the list of registered heroes to its corrupt successor agency H.A.M.M.E.R. This agency is dismantled as well, and Iron Man organizes the Avengers to replace these agencies. He founds a clean energy company, Stark Resilient, and fakes his death so his enemies will not threaten it. He joins the Guardians of the Galaxy for a time, and upon returning to Earth, he discovers he had actually been adopted by the Starks so their biological son could be hidden from an alien threat.
While they fight Red Skull, a spell cast by Victor von Doom and the Scarlet Witch temporarily inverts the personalities of several heroes. The new morally corrupt Iron Man protects himself from the counterspell and takes over San Francisco to augment the residents with Extremis. When a man is discovered who can see the future, the superhero community undergoes another schism, and Iron Man leads a team of heroes opposed to a predetermined justice system based on his ability. The battle ends with Iron Man in a coma. A reformed Victor von Doom becomes Iron Man, while an artificial intelligence backup of Stark's mind guides a new armored superhero, Ironheart. Stark resumes his work as Iron Man after the technology in his body allows him to heal. He then allies with Emma Frost and marries her to set a trap for their common enemy Feilong.
