Reed Richards is supposed to be the smartest man in all of the Marvel universe, and like most highly intelligent people he's an egotistical jerk. We're not even talking about the fact that he actually calls himself Mr. Fantastic without even a molecule of irony (We note that Sue Storm apparently isn't allowed to call herself Mrs. Fantastic), or even that he basically flew his family into space in an untested ship that totally ran into the exact danger he was warned about but was too smug to bother with.
Even going beyond all those things, Richards still has managed to behave in a manner that for all intents and purposes is exactly how a supervillain would. There have even been instances when his actions made Dr. Doom's look positively benevolent. Here are the ones that most irked us.
