Buffy the Vampire Slayer: Doppelgangland

"Doppelgangland" is the sixteenth episode of the third season of the fantasy television series Buffy the Vampire Slayer (1997–2003). It was written and directed by the show's creator, Joss Whedon, and originally aired on The WB Television Network in the United States on February 23, 1999. The episode's title is derived from the term "Doppelgänger", a German word for a lookalike or double of a living person. "Doppelgangland" revisits the alternate reality portrayed in "The Wish", in which Buffy never arrived in Sunnydale and vampires ruled the city. Anya, a vengeance demon who previously granted the wish, attempts a spell to regain her powers.
