Hey, some of us haven't quite beat X here :mad:
Anyways, for me, Kuja and Kefka are honestly the only main villains I liked. Kuja had a motive and was largely developed, so you could empathize with him. Most of the other villains (Ultimecia, Garland, and Ex-Deaths to name a few) just never had that development. Kefka is just plain crazy, and I like that. :cool:
As far as secondary villains go? Well, we have Cid from Final Fantasy XII, another crazy pal of ours. There was also Gilgamesh from FFV, who was just plain awesome :D But that's about it really. Honestly, villains haven't exactly been the series' strong point. Its more of, he's EV1lL and you must stop him.
