#4 Iron Man (Tony Stark)
Sport: Formula Racing
Genius, billionaire, playboy, philanthropist, race care driver... Tony Stark, A.K.A the Iron Man, could be any of those in a little less than a heartbeat.
A self-styled maverick flyer, he sometimes dabbles in the enthralling world of Formula Car racing. The last time he did so, in Monaco, a bad, mad Russian villain put an end to his plans.
But irrespective of the sudden stop to his career as a racecar driver, he has shown a great passion for it. So if Iron Man ever decided to power down his Arc Reactor, he wouldn’t have to wander far in search of an alternate career.
