Jason Todd is a prime example of this in the Batman comics - he has dark troubled past (even before he died and then came back), he's a bad boy rebel who wears a leather jacket, he can become a completely psychopathic maniac (see Battle For The Cowl)and STILL count on his fiercely loyal female fanbase to defend him, and to top it all off he was voiced by Jensen Ackles in Under The Red Hood.

I thought this trope was supposed to be Fangirl Bait, not Male Character I Think Is Hot.
