I'm not saying Kid Buu was the weakest, that would be Grey Buu. What I meant to say was that while Kid Buu was not the strongest he was the most dangerous because of the sheer insanity he had.

Back to Supernatural, I think it's in their plan where the Levi win as most dangerous. Yeah, the Archangels would have killed a third of the planet but the rest would be in Paradise. With the Leviathan all of mankind (except maybe Canadians) would have been turned into cattle.
