This poll allows you to pick up to two options. If you do more than just two options fairly equally, I might recommend Other by itself or in conjunction with another choice (if you lean more toward good or evil in some way).
As for me, I picked villains for mine. The reasons? They tend to get a lot more attention, and I am under the impression they are in shorter supply in stories and roleplay. After all, no great heroes arise without an evil to brave. The tragic antihero (perhaps someone with originally pure motives who turned into a mere corruption of his or her former self) can provide a lot of compelling background story in my opinion, and mustache-twirling villains I've often found useful for comical effect (admittedly, I am not the best at it, but I am practicing!).
