Angel is a fictional character created by Joss Whedon and David Greenwalt for the American television programs Buffy the Vampire Slayer and its spin-off series Angel. The character is portrayed by actor David Boreanaz. As introduced in Buffy in 1997, Angel is a love interest for heroine Buffy Summers (Sarah Michelle Gellar), a young woman whose destiny as “the Slayer” is to fight the forces of evil, such as vampires and demons. However, their relationship is complicated by the fact that Angel is himself a vampire cursed with remorse and a human soul, which motivates him to assist Buffy in her duties as Slayer. The character’s popularity led to the production of the spin-off Angel, which follows the character’s struggle towards redemption after moving to Los Angeles. In addition to the two television series, the character appears in the comic book continuations of both series, and much other expanded universe literature.
