Who is your favorite TV villain?

We've all watched that one TV show that made us appreciate the villain for absolutely killing their role. I'll go with Klaus Michaelson from The Vampire Diaries. The guy was badass throughout the series, it's like he was born to play that role.
Another person I will choose is Severus Snape of Harrypotter.

Who’s your favorite villain?

Klaus Michaelson's story was better portrayed in the TV show - The Originals. It's like you haven't watched it yet? He was a complete monster.

My all time favourite villain in a movie or TV show is Dr. Doom.
