Cowards

Antagonists that prefer to run away from a fight/confrontation, their own problems, or who pick on those who they find weaker, and even pray for mercy once they are overpowered. Some good examples of cowards include Dolores Umbridge, Flintheart Glomgold, Syndrome, Napoleon (Animal Farm), Prince John, Scar, Professor Zündapp, Miles Axlerod and Lots-o'-Huggin' Bear.

However, note that some villains who show fear aren't always considered cowards if their fear is reasonable given the situations they find themselves in. (e.g. Hopper, Plankton, Lord Shen, Koba, Katz, Cat R. Waul, Ratigan, Bill Cipher, Oogie Boogie, William Afton, Dr. Facilier, Rasputin (Anastasia), Agatha Trunchbull and Judge Claude Frollo). They may even be considered quite brave otherwise.
