The Final Fantasy series has many great villains. I'm sure if you took a poll of all fans, the winner would be Sephiroth for greatest villain of the series. While I think he is pretty good, here are some other fantastic villains from the series for your consideration.
I would say the best villain in the epic ff series would be Caius Ballad, in final fantasy 13-2.
The Best Villain in my opinion, as a villain not a character would have to be Kefka, because, he unlike any other final fantasy game, succeeded in his goal, destroying the world.
The main villain in Final Fantasy VII is Sephiroth
The main villian in Final Fantasy 7 is Sephiroth.
~SEPHIROTH~
Sephiroth <3
The best villain in a broad sense would be Kefka from Final Fantasy 6 (3). He's got it all. Insanty, delusions of grandeur, sadism, and a wicked laugh.
Depends on how you define "best". Best story=Final Fantasy X. Best graphics=Final Fantasy XII. Best gameplay=Final Fantasy X-2
Final Fantasy VI
No.
The main character is Terra Brandford, and the main villain is Kefka.
Arguably, Final Fantasy VI or VII is consider the best game in Final Fantasy series. Although Final Fantasy VI get little more praised, Final Fantasy VII is more loved because its wider appeal.
