Stark was also the creator of the artificial intelligence JARVIS, which assisted the team in their operations. During his time on the team, Stark worked alongside Captain America, Black Widow, Hawkeye, Ant-Man, Thor, Captain Marvel and the Hulk.

Taking the identity Iron Man, he became a founding member of the Avengers after an encounter with Loki. To achieve this, he developed an armored suit fitted with many technologies, including Repulsors and an Arc Reactor. At some point, he was romantically involved with his secretary Pepper Potts, though it presumably ended badly.Īfter a brush with death, Stark decided to become involved in personally protecting civilians from hostile threats. Initially developing weapons technology for organizations like SHIELD, Stark turned a blind eye to those using it, believing he was not responsible for how his technology was used. While making his own for the company, he also finalized the designs of his late father's designs, including that of the Helicarriers and nuclear warfare. The son of technology mogul Howard Stark and his wife Maria, Tony inherited the business after their deaths.
