@KingValeska everyone you listed is under psychopaths.

As for villains who are neurotypical (not psychopath, mentally ill or psychotic): Isaac Ray Pelham Westcott, Contagion (Marvel), Imran Zakhaev (original) and Demise.

My mistake. I forgot they were.

King dice/ The Devil

Peter Griffin

T-1000, Skynet, Terminators.

Brainiac

I was about to say AM, but then I checked the categories.

Anyways, I would say Bill Cipher (A bit debatable) and Adam from NGE. (Bill tried to mess up all of reality for laughs and Adam tried to start the third impact)

@Monothinman4596 Why you say debatable for Bill

Bill is debatable for me because he seems pretty unhinged.
