Here's some of mine:

Bill Cipher (Gravity Falls)

Father (Fullmetal Alchemist, especially the manga, as the anime reduced some of his scenes)

The Master (classic Doctor Who, from Roger Delgado until Eric Roberts)

One of my standards for favourite characters/shows is that they have to be original concepts, not relying on anything to exist. And all those three villains and the shows (or the manga in Father's case, to be exact) all qualified.

A honorable mention would be Blood Stalk from Kamen Rider Build, but unfortunately I don't know much about this character nor Kamen Rider, so I would just leave it there.
