Buffy The Vampire Slayer: 10 Most Underused Characters

10. Drusilla

Introduced in the show's second season, Drusilla was portrayed as the crazed and unpredictable paramour of Spike. With psychic abilities and a mysterious connection to Angel, later revealed to be her sire and the man who tortured her into insanity, Dru was a magnificent villain who killed Kendra, the new Slayer in town, and was taken away from Sunnydale by a fleeing Spike.

Played with gleeful twistedness by Juliet Landau, Dru had a brief stint in Angel's first season but didn't appear on Buffy again until season five, as a means of showing the audience how much Spike was now in love with the Slayer.

Unfortunately, that's Dru's role in a nutshell. Despite her tragic and dark backstory, her powers of hypnosis and her sheer entertainment value, she appeared only sparingly, and was always there to add to Spike's arc, rather than have any time to shine in her own right.

Of Angel's old clique, she's the only one who never got time on her own to show what she was made of, and to top it off she didn't get a big send-off, either, her final fate never revealed on the show.
