I'm going to do this according to final bosses, I would say Li-Grim from Final Fantasy Tactics Advance because of her beauty.
Jihl Nabaat is very pretty too
Even though I'm not fond of him, Cid Raines is pretty good looking
Sephiroth is very good looking
Best looking as in physical attractiveness, or most interesting design? Kuja is arguably the most attractive villain in the series - his physical beauty is a major part of his character and personality, in fact - whereas my personal favourite villain design is Golbez. -- ∙ ∙ 13:11, April 16, 2013 (UTC)
Beauty is in the eye of the beholder, in my opinion, Exdeath's design is just kickass.14:40, April 16, 2013 (UTC)
