Worst CBM villain

[Rowsdower!]

Really? I loved Kevin Bacon's Sebastian Shaw. I don't know the character that well so I'm not sure how close he was to the source material but I thought he was a great villain.

Hey, has anyone mentioned Faye Dunaway in Supergirl yet?

Whiplash was the first one that came to mind. The second was Electro.
