I want to amend, evil characters still is totally true(!), but...hybrid characters, as in the case of genetically spliced Allagan characters. While camping for Ultima in what I am now deeming a case of momentary insanity, I was thinking, "Wow, really cool that I am gonna get these horns! Wouldn't that be so interesting to have a character that escaped from Azys La after the MSQ happens, and then sort of lived among all the normal people of Eorzea...but had these awesome horns since he is crossed with Ultima or a Behemoth or something!". Then promptly slapped myself in the head, and realized how far out of my normal play style and character creation that would be...I still think it kind of a cool idea though...
