Im really caught between Girham and Majora.
Girham is just silly fun for a villian and he totally reminds me of bowie.
But Majora is just a brilliant villian. He sees this whole world terror thing as a game, he has the mind of a child, but not only the mind of some kid, but an abused one. He just does all this disturbing shit cuz he thinks its normal, he isn't the villain that wants to watch the world fall, but he only does this for the sake of doing it. Majora IS evil, and thats just so terrifying.
