Least: Ultimecia.
What about you?
Well anyway:
Favourite: Kefka/Kuja
Hated Most of All: Sephiroth
Favourite: Kuja or Exdeath
Least favourite: Ultimecia.
Exdeath was great. He was pretty great all throughout the game, he destroyed quite a lot of the map using the void, he commanded an army of interesting demons and he could transform into a freaking splinter. Also, his signature quote ‘Time for your viscera to see the light of day!’ fits him very well.
Kuja was probably the best. He seemed evil enough and he was seen quite a lot during the game. I liked his fascination with theatre as well, it was quite entertaining.
I suppose if I had to rank them based on favourites I would go:
Kuja > ExDeath > Kefka > Sephiroth > Ultimecia > Emperor > Garland.
I don’t remember enough of Golbez and FFIII’s antagonist to list them.
Least Favorite: Kefka; he is a stupid looking, bumbling clown if it wasn’t for real-life developers forcing him in one direction.
