If someone would be considered as the best villain on the series, I would vote for Krueze. Why? It's just his the best candidate for the position. Traditional villain would be like someone sitting in a chair, petting a some kind of pet, laughing the traditional laugh, (muahahahahaha) If this was the case, Djibril would fit best, but Krueze was a new kind of villain, if possible better kind. He put so much effort into devicing a some sort of twisted scheme. I also like the fact that he gives us the view of him being so mysterious in everyway. I also like his motive of why he is being like that, unlike straight forward reason such as world domination, or annihilation of coordinators. His character development I must say is deep, and having that mask gives more of that feeling or villainy. Not only am I a fan, but Krueze owns everyone!!!!
