Ok so this isn't a good list. A sequel would almost certainly be placed in the forgotten realms, which makes half of this list invalid. And as for some of the other ones such as Tiamat, you can't "one up" that, so it would be challenging to continue the franchise. Whoever wrote this list cleary possesses only a superficial comprehension of the subject matter, and should research it more before making this kind of post. Some of the Villains just make me think "Ok, and...?" Because they are too small for the kind of movie we would be talking about. Please consider obtaining anymore profound understanding of this topic before creating these lists, this is literally just spreading misinformation.
