"Dark Lord" seems to be a popular title for villains in fantasy and science fiction, whether as an official title or merely a self-proclaimed one. All tend to be very scary and decidedly dark; as such, caution should be exercised around such characters during missions, especially if they are still relatively in character.
Some prominent Dark Lords include:
- Voldemort (Harry Potter)
- Sauron and Morgoth (The Lord of the Rings)
- Most Sith Lords, but particularly Emperor Palpatine (Star Wars)
- Crayak (Animorphs)
- Yawgmoth (Magic: The Gathering)
- Soth (Dragonlance)
- Xykon (Order of the Stick)
