Drusilla or Dru, is a fictional character created by Joss Whedon and David Greenwalt for the American television series "Buffy the Vampire Slayer" and "Angel". The character is portrayed by American actress Juliet Landau. Drusilla is introduced alongside her lover Spike (James Marsters) and her sire Angel (David Boreanaz) in the second season of "Buffy the Vampire Slayer" to serve as new antagonists to the series' heroine, vampire Slayer Buffy Summers (Sarah Michelle Gellar) and alongside Darla (Julie Benz) and Wolfram & Hart as the main antagonist of the second season of "Angel". In contrast to the series' previous central villain, the ancient and ceremonious Master (Mark Metcalf), Spike and Dru were introduced as a more unconventional but equally dangerous pair of vampires.
