Iron Man, the alter ego of Tony Stark, is in my opinion the best of the superheroes. As Iron Man, the dude can fly, he can deflect bullets, and he can generate energy pulses which can take out tanks and missiles. With that suit, he can do just about anything. Maybe he should pull a Leonardo DiCaprio and scream, "I'm the king of the world".
There are issues when you are trapped in a tin can though. What about his ability to use the bathroom when he's wearing that suit? Really, if you think about it, does he have some type of trap door to let him take care of business? What if nature calls, you've got to go right? Does he have some type of switch that let's him drop his iron pants down? Don't even get me started about the logistics of cleaning one's backside while surrounded by metal. What a mess. But then again, maybe I don't want to think about it.
As Tony Stark, the billionaire playboy, weapons industrialist, this guy should have women falling all over him. Now don't get me wrong, Pepper Potts is a downright hottie. No doubt about it. But is she hot enough for a billionaire? He is a billionaire, he can fly and do some ridiculous things in his Iron Man suit. He's a hero, a CEO, but after a long day at the office or fighting some villain he goes home alone. This guy has got to start enjoying his life a little bit more. On the other hand, when you are a superhero like Iron Man, who do you hang out with? Other superheroes? Where would they go, to the local superhero lodge and shoot the bull, arm wrestle each other, slam down a few and tell stories about how invincible they are. Make plans for the next rumble with evildoers? Really, I think Tony must sit there and say to himself, I need some "me" time. I'll call my therapist and see when I can get an appointment."
