10 Best Buffy The Vampire Slayer Villains

10. Caleb

Caleb (Nathan Fillion) was introduced in season seven as an agent of that season's Big Bad, the unseen, manipulative First Evil. For a long time, the First Evil had been working its magic by way of manipulation, brainwashing and a group of sinister foot soldiers called the Bringers. But with Caleb, the First Evil finally had a powerful vessel - a committed follower and brutal warrior.

A priest who constantly quotes the Bible and makes obscure references to its teachings, Caleb is nothing short of awful. Though seemingly righteous and good-hearted, he quickly reveals himself to be a rampant misogynist and a murderer hoping to be filled with the First Evil's power.

He spends his tenure on the show hidden in a vineyard, protecting an ancient scythe and plotting with his master. When Buffy (Sarah Michelle Gellar), Spike (James Marsters), Xander (Nicholas Brendon) and the Potential Slayers attack the vineyard, Caleb is able to best them all in combat, killing Slayers left and right, knocking Buffy and Spike around like ragdolls, and taking Xander's eye in an act guaranteed to make you squirm.

Watching Buffy finally cut him in half was a welcome demise.
