Exacta, Fire

People may think he devolved into a god-complex entity near the end of the series zenith, but he had every right to be. Everyone was so beneath him, and he was so well prepared, planned, and powerful in comparison to all of the would-be heroes and anti-heroes who stood in his way. He planned everything to a T and nearly won the whole war singlehandedly.

I still rank him pretty high as one of the best villains of Anime :)
