The Evil Kefka
Worst of the worst, there is no way around hating this twisted maniac. Not above taking many lives without need, and in fact quite fond of it, Kefka has commited every atrocity imaginable. From betrayl, to murder, to just plain being ugly, he rejoices in the sounds of pain and death. He is also the Ultimate Boss of FF6/3.
Some of Kefka's Atrocities:
Kefka has commited many crimes against the people in the fictional world of FF6/3. He has poisoned the people of Doma, stabbed General Leo in the back (literally), destroyed the Esper race, released powerful monster upon the world after splitting the face of the planet apart, murdered his own emporer, attempted to destroy all of the main characters in the game, enslaved Terra, and betrayed countless individuals (such as Shadow) many times.
Kefka's Power
As you may know, Kefka eventually steals the power of hundreds of espers to become a mighty magical being. What does he use is dark powers for? Why, destroying the world, of course! Even after he moves the statues and alters the planet forever it isn't enough. Kefka takes over the world with an iron fist, and in two short years has every surviving person shaking in their shoes as he revels in the sounds of death and dismay. Not only that, but getting all that power makes him very hard to beat. Still, Kefka's strength is nothing compared to the strength of several very angry heroes!
