I vote for Unicron.... as been said, he ate fucking planets... and he went out of his way to eat planets. And then could turn into a robot that had to be the size of a solar system...
Skeletor is a close second... cause he is the root of all evil...
unicron? the guy sleeps for eternity and when he finally wakes up he can't even defeat a collection of miniature toys. but he eats planets...he eats my anus!

no doubt...he gets defeated by a robot who can transform in to something you can use to haul lettuce across country.
