Out of the scrapped animated films, I think Disney/Pixar's Newt would've been interesting.
Would this be your answer?
It was indeed called Kingdom of the Sun before creative differences changed the film into The Emperor's New Groove.I honestly think that I would prefer the original version of The Emperor’s New Groove, Kingdom of the Sun (or whatever it was called).
I watched The Secret of Nimh for the first time tonight (yes, I know). I... didn't love it. (ducks shoes)
It also doesn't help the fact that said foes are similar to the villains of Spider-Man 2099.As much as I enjoy Batman Beyond, I find the show’s rogues gallery of original to be extremely lacking. Inque is the only good, fully utilized villain. The rest are either dull or underused.
