Mine would have to be Judge Frollo. Enough said. That guy is just EVIL!
Eh...not really "evil". Frollo's religious fervor drove him nuts, but in the end, he was nothing more than a self-tortured soul trying to make everyone live a righteous life. He's the Disney version of Fred Phelps...a crazy old coot trying to make the world a better place (in his own deranged opinion).
My vote for most evil...Professor Ratigan.
Just listen to his villain song...
The World's Greatest Criminal Mind said:
Okay, sure Captain Hook threatened the Lost Boys and attempted to coerce Tiger Lilly into giving Peter up by threatening her with drowning. But he never actually SUCCEEDED. Ratigan? Not only did he succeed, but his minions SING ABOUT IT with glee, then dress him up as a King.
AND THEN...he feeds one of his minions to his pet cat. Why? Because the guy, obviously in a drunken stupor and meaning no harm, INSULTED him.
And....he's based on a mixture of two of fiction's greatest villains,
Professor Moriarty and James Bond's arch nemesis
Blofeld.
Plus an extra ten points for being voiced by Horror Icon Vincent Price.
