You mean plundor?
I mean a rabbit headed man with the body of a builder who wants to foil He-Man's plans? come on! i mean the episode is great but the villain is too goofy for words.
"You killed Captain Clown, YOU KILLED CAPTAIN CLOWN"-Joker.
I was under the impression that the character was a parody - a world where Bugs Bunny rules all the cartoons, so to speak.
If by goofiest you mean greatest supervillain ever then yes he is. As for people saying he's the worst...I have but one word...Crackers
