Arrogance is a common trait amongst villains. But I got to thinking out which heroes have this trait. Now, the line between arrogance and confidence can be razor thin, bit IMHO, two come to mind.
1) Batman: Has Worked with Gods/Demi-gods, heroes with universal experience (Like the Lanterns) and folks you have to assume are smarter than him (Ray Palmer), yet he still stubbornly insist things be done his way.
2) Reed Richards: Goes back to the inception of the FF when they named themselves. Two named themselves after their new-found power-set. (Human Torch, Invisible Girl) and one said "He was what Sue called him, a "Thing". What does Reed name himself? "Mr.Stretch"? Nope. "Elastic-man?" Nope. He goes with "Mr Fantastic" KInda says it all. (Point taken from a line Doom had during Waid's run on the FF.)
So, who else qualifies?
