is Ansem a totally original strictly KH character?
i know it's a terribly noobish question but i don't care.
he just seems so random to me. is there any background on him besides all i know: he was a king somewhere and an asshol3 who screwed with worlds and ..magic or something

im not 100% on the whole princesses thing. they had pure hearts to power something he wanted to do right? to open a door to pure darkness? i forget
