Robert Downey Jr. plays Tony Stark, a.k.a. Iron Man, in Marvel's The Avengers. Tony describes himself, when he's not in his Iron Man uniform, as "Genius, billionaire, playboy, philanthropist." In his Iron Man uniform, he is practically invisible.
It's not only the suite that makes Iron Man a super hero, though. Beneath the suite, Tony Stark's quick intellect allows him to find a way out of the most impossible situations. Add to that his relentless unwillingness to back down and his supreme confidence in his own victory, and you've got quite the hero.
