I've been doing the Iron Man thing for the last two years.

[Admittedly, his model is pretty lazy. Eighteen years old with two years experience fighting and the hand to hand skills to take on professional assassins without the Iron Man suit, plus slightly enhanced strength from a drop of experimental super-soldier serum... he should probably look a teensy bit more grown up than the show model.]

Superthugs, suits based on tech stolen from me, a guy who took an experimental super-soldier serum that made him near invincible, an alien invasion led by a guy with ten rings that could alter reality itself.

And another Bruce Banner, of course, but we managed to stay on friendly terms after the first time he beat my head into a wall.
