This is a just for fun thread. Who is the most evil "Dark Lord" of the IMHO Big Four fantasy/sci-fi film series? Lord Voldemort (Harry Potter) Sauron (Lord of the Rings) Emperor Palpatine (Star Wars) Thanos (Marvel Cinematic Universe) So which death conquering, all powerful, super Dark Lord is the most evil? My vote goes to Thanos. At times: Voldemort controls a wizarding world, Sauron controls much of an entire world, Palpatine controls a galaxy, and Thanos controls a universe.
