I would have to say Kuja's.
The Music...
Well, all I can say is that it's great and it fits perfectly with the entire introduction scene for Kuja.
The Setting...
An ongoing torrential downpour as Kuja looks down on upon Zidane, Vivi and Freya as if they were nothing to him.
My Reaction...
Pure excellence. Everything put together gives the feeling that Kuja is an all-powerful villain. The best entrance I have seen for a villain.
