Anton Vanko died in Moscow the day Tony Stark told the world he was Iron Man. That day Ivan Vanko prepared to make his own armor, including an Arc Reactor in order to kill Stark. He took a plane to Monaco six months later after getting the ticket from a Ten Rings Agent.
While racing in Circuit de Monaco in Monte Carlo, Monaco, Tony Stark's car is attacked by Ivan Vanko, using his homemade armor. After crawling out of his car and dodging many attacks from Vanko, Happy Hogan and Pepper Potts hit Vanko with their car and pinned him against the fence. Pepper throws Stark his Mark V armor briefcase. Vanko hit Stark with his whip and Stark grabbed it. Stark pulled himself closer to Vanko and ripped the homemade Arc Reactor from Vanko's chest plate, crushing it. As his suit lost power, Vanko was arrested and his armor was taken from him. However, he taunted Stark with a phrase 'you lose' as he was taken into custody.
- "I've been on the phone with the National Guard all day, trying to talk them out of rolling tanks up the PCH, knocking down your front door and taking these. They're gonna take your suits, Tony, okay? They're sick of the games. You said nobody else would possess this technology for 20 years. Well, guess what? Somebody else had it yesterday. It's not theoretical anymore."
- ―James Rhodes to Tony Stark

Tony Stark discovered that Ivan Vanko was the son of Anton Vanko, who collaborated on the first Arc Reactor with Stark's father Howard. Vanko was promptly broken out of jail by a revenge-seeking Justin Hammer, who put him to work fashioning a line of armored combat suits that he planned to use to upstage Stark at Stark Expo.
