The Scourge was the chief antagonists of the Angel episode "Hero" and are notable for being one of the few one-shot villains in a show to succeed in killing off the main character - in this case, Doyle, who sacrificed his own life to stop their xenophobic quest to exterminate all "non-pure" species.
The Scourge was an army of pure-breed demons bent on the extermination of every non-pure demon race on earth, as well as that of humanity itself. To this end, they sought to eliminate a group of Lister demons currently hiding in Los Angeles, intending to test their latest weapon, the Beacon- a device that emitted a light that destroyed anything with human blood that it came in contact with- on the Listers. Although Angel Investigations attempted to sabotage their attempts by having Angel infiltrate the group- claiming to loathe his 'half-breed' status- while they helped the Listers escape on a cargo ship, the betrayal of the ship's first mate allowed the Scourge to get the Beacon on board the ship, the Beacon only being deactivated thanks to Doyle's sacrifice.
Charles Gunn and Illyria, a reincarnated demonic deity possessing body of human named Winifred Burkle, stumbled across the Scourge while away from the Angel Investigations team, who stole a high-tech laser cannon called the Mutari generator (this device was once used to weaken Illyria) as part of their latest plan to destroy humans and non-pure demons. Scourge used the Mutari generator to resurrect and empower Baticus, an old enemy of Illyria and the last of the Darque Wurm race. Though Baticus easily overwhelmed Illyria, the Scourge's plan ultimately failed when the stress of containing the power destroyed Baticus' body.
- The Scourge are clearly inspired by the Nazis, especially the death-squads responsible for the infamous Holocaust.
- The Scourge also bare similarities to Ken and his minions, the antagonists of the Buffy episode "Anne".
