Tony Stark (Robert Downey Jr)

 Anthony Edward Stark is a fictional character primarily portrayed by Robert Downey Jr. in the Marvel Cinematic Universe (MCU) media franchise—based on the Marvel Comics character of the same name—commonly known by his alias, Iron Man. Stark is initially depicted as an industrialist, genius inventor, and playboy who is CEO of Stark Industries. Initially the chief weapons manufacturer for the U.S. military, he has a change of heart and redirects his technical knowledge into the creation of mechanized suits of armor which he uses to defend earth.

Stark becomes a founding member and eventual leader of the Avengers. Following his failed Ultron Program, the internal conflict within the Avengers due to the Sokovia Accords, and Thanos successfully erasing half of all life in the Blip, Stark retires, marries Pepper Potts, and they have a daughter named Morgan. However, Stark rejoins the Avengers on a final mission to undo Thanos' actions. He engineers a time travel device and the Avengers successfully restore trillions of lives across the universe. However, Stark inevitably sacrifices his life to defeat Thanos and his army. Stark chooses Peter Parker as a successor.

Stark is one of the central figures of the MCU, having appeared in eleven films as of 2023. The character and Downey's performance have been credited with helping to cement the MCU as a multi-billion-dollar franchise, with Stark's evolution often being considered the defining arc of the series.^[4]

Alternate versions of Stark from within the MCU multiverse appear in the animated series What If...? (2021), voiced by Mick Wingert.

Becoming Iron Man

In 2010, Stark travels to war-torn Afghanistan with his friend and military liaison Lieutenant Colonel James Rhodes to demonstrate Stark's new "Jericho" missile. After the demonstration, the convoy is ambushed and Stark is critically wounded and imprisoned by a terrorist group, the Ten Rings. Fellow captive Ho Yinsen, a doctor, implants an electromagnet into Stark's chest to keep shrapnel shards from reaching his heart and killing him.

Stark and Yinsen secretly build a small, powerful electric generator called an arc reactor to power Stark's electromagnet and a suit of powered armor. When the Ten Rings attack the workshop, Yinsen sacrifices himself to divert them while the suit is completed. The armored Stark battles his way out of the cave to find the dying Yinsen, then burns the Ten Rings' weapons in anger and flies away, crashing in the desert. Rescued by Rhodes, Stark returns home to announce that his company will no longer manufacture weapons. In his home workshop, Stark builds a sleeker, more powerful version of his improvised armor suit as well as a more powerful arc reactor.

Stark learns that Obadiah Stane has been engaged in arms trafficking to criminals worldwide, and is staging a coup to replace him as Stark Industries' CEO. Stark, in his new armor, flies to Afghanistan and saves the villagers. Stane ambushes Stark at his home and takes the arc reactor from his chest, revealing that Stane was responsible for Stark's captivity. Stark manages to get to his original reactor to replace it and defeats Stane. The next day, at a press conference, Stark publicly admits to being "Iron Man."
