Judge Claude Frollo.
Movie: The Hunchback Of Notre Dame (1996).
Info: Frollo is one of Disney's darker villains along with Sid from Toy Story (1996) and Judge Doom from Who Framed Roger Rabbit (1988). Like Sid and Doom he likes to murder and torture his victims in cruel ways and commits genocidal acts against races they depise. He often burns gypsies on fire or kills them simply with a sword (or in this case a lightsaber or sith lightning).
Movie: Star Wars Saga (1978 - 2005).
Info: Also known as Emperor Palpatine. The man who is responsible for turning Anakin Skywalker into Darth Vader/The Dark Lord Of The Sith. He was the first Sith lord that used Sith lightning in a Star Wars film.
Let me know. Who would win? Lord Frollo or Lord Sidious? I called Judge Frollo Lord Frollo because he's Disney's Darth Sidious. Let's debate.
