Correct me if I'm wrong, but there're only two types of villains:
"Fun isn't something one considers when balancing the universe, but this... does put a smile on my face. If life is left unchecked, life will cease to exist."
"I hate all forms of goodness, and I hate all those which do not kneel in my presence! I shall now lay down the first steps of my evil monologue-worthy plan to signify my villainous duties!"
