Fantasy animated shows search!

It's not a tv series, but if you want animated fantasy I'd add in the Disney movie The Black Cauldron to your list. Okay ignore the annoying kid and his pig, and especially Gurni, but you do have an army of evil creatures (I think they're orcs/goblins), led by a horned lich as well as wyverns, witches and a few other things. If you ignore the cutesy bits, it's a really good mine of ideas for D&D.

I don't know where you draw the line between fantasy and sci-fi, but there was a Flash Gordon cartoon by Filmation I used to watch as a kid that I think was much more fantasy-like than sci-fi.
