The Iron Man

If Iron Man was a real superhero, he wouldn't be some rich genuis in an obviously not iron suit. He'd be some poor shmuck that stole some iron and created some ugly little armor. I bet he'd think he'd be unstoppable but the dude would get killed in an instant. Imagine rolling up to a guy with a thin sheet of metal around his body. If you'd have a shotgun, he'd be toast.
