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.
"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."
