Iron Man 2
In Russia, the media covers Tony Stark's disclosure of his identity as Iron Man. Ivan Vanko, mourning the death of his father Anton Vanko—a former Stark Industries employee, sees this and builds the same miniature arc reactor as Stark's using old Stark Industries blueprints left behind by Anton.
Six months later,[b] in an effort to continue the legacy of his father Howard, Tony re-institutes the Stark Expo in New York City's Flushing Meadows–Corona Park and resists pressure to turn over his armored suits to the government and Stark's rival, Justin Hammer. Stark learns that the palladium core in the arc reactor that keeps him alive and powers the armor is slowly poisoning him, and he is unable to find a substitute. Growing increasingly despondent about his impending death, and refusing to tell anyone about his condition, Stark appoints his assistant Pepper Potts as CEO of Stark Industries and hires Stark employee Natalie Rushman to replace her as his assistant.
Stark competes in the Monaco Historic Grand Prix, where he is attacked in the middle of the race by Vanko, who wields electrified whips powered by his arc reactor. Stark dons his armor and defeats Vanko, but the armor is severely damaged. Vanko explains that he intended to prove to the world that Iron Man is not invincible. Impressed by Vanko's performance, Hammer fakes Vanko's death while breaking him out of prison and asks him to build a line of armored suits to upstage Stark. Vanko decides that unmanned drones are better to eliminate the human factor.
During his birthday party, Stark gets drunk while wearing the Iron Man suit. Annoyed by Tony's recklessness, Stark's best friend, U.S. Air Force Lieutenant Colonel James Rhodes, dons Stark's prototype armor and tries to restrain him. The fight ends in a stalemate, and Rhodes confiscates the prototype armor for the U.S. Air Force. Nick Fury, director of S.H.I.E.L.D., approaches Stark. Fury reveals that "Rushman" is S.H.I.E.L.D. agent Natasha Romanoff and that Fury personally knew Howard Stark, who was a founder of S.H.I.E.L.D. Fury explains that Vanko's father and Howard invented the arc reactor together, but Howard had Anton deported when the latter tried to sell it. The Soviets then sent Anton to the Gulag. Fury gives Stark some of his father's old material. In a diorama of the 1974 Stark Expo, Stark finds a diagram of the atomic structure of a new element. With the aid of his A.I., J.A.R.V.I.S., Stark determines it can replace his arc reactor's current palladium core, and successfully synthesizes it.
When Stark learns that Vanko is still alive, he goes to Hammer's expo. As Hammer unveils Vanko's armored drones, they are led by Rhodes in a heavily weaponized version of the prototype armor, dubbed "War Machine". Just as Stark arrives to warn Rhodes, Vanko takes remote control of all the drones and Rhodes's armor and attacks Stark. Hammer is arrested for breaking Vanko out of prison while Romanoff and Stark's bodyguard Happy Hogan infiltrate Hammer's factory. Vanko escapes, but Romanoff gains access to Hammer Industries software and returns control of Rhodes's armor to him. Together, Stark and Rhodes defeat Vanko and his drones. Vanko dies by suicide by blowing up his suit and the drones.
