If you've seen the last season of Sailor Moon, then my vote would be for Galaxia. She would have, SHOULD HAVE, completed her conquest of earth had it not for the oh-so convenient deus ex machina plot device. So very close--she had already snuffed out half the souls on Earth and almost ALL of the Sailor Senshi.Originally posted by I.R Joey
Let's not just think in terms of power either. I guess alot of these people are comic villans though
Maybe one of the DBZ villans with powers like Buu, Cell, and Freeza (Freeza has a whole army at his disposal.)
Darkseid would be dangerous, see the way he nearly took Earth? If Orion and Co. hadn't shown up we would have been dead.
Maybe Thanos from the SS cartoon (with the infinity gauntlet)
