Adaptational Villainy Part I
Every so often, you'll see a character from a story of some kind or another who in a subsequent adaptation or alternate reality comes out looking a heck of a lot worse than they were in the original story. When this happens to also make the character a straight-up villain/antagonist, it means we've got a case of Adaptational Villainy. Now Adaptational Villainy comes in one of two forms:
1. Characters who were not villainous in the original story, but are in the adaptation.
2. Characters who ARE villainous in the original story, but are even worse in the adaptation. Examples of this include Bolivar Trask in Days of Future Past, Catwoman in most adaptations, Shredder in the 2003 cartoon, and so on and so forth.
And so with that out of the way, here is a list of examples of Adaptational Villainy. Note that I will not be including any real life examples or ones from Abrahamic Religions.
