Halfrek

Halfrek is a recurring character in the television series Buffy the Vampire Slayer. Played by actress Kali Rocha, Halfrek is a vengeance demon, a being whose purpose is to grant wishes to those who have been wronged, specifically in the realm of romantic relationships and friendships.

Like other vengeance demons, such as Anya Jenkins (Anyanka), Halfrek can grant wishes that cause significant chaos and often unintended consequences. She possesses abilities including teleportation, manipulating reality to fulfill wishes, and a degree of invulnerability. She is portrayed as older and more experienced than Anya, often acting as a mentor or advisor to her early in Anya's attempts to become human.

Halfrek has a sardonic wit and a casual approach to her work, often downplaying the magnitude of the damage her wish-granting causes. She exhibits a particular affinity for causing pain to children, a trait that ultimately leads to her demise.

Halfrek's history is largely unrevealed, but it is implied that she has been a vengeance demon for centuries. Her true name is not disclosed in the series.

Halfrek meets her end in the episode "Selfless" when Anya, in an attempt to reverse a wish that had gone horribly wrong, inadvertently wishes that Halfrek had never been a vengeance demon. Willow Rosenberg then uses magic to enact this wish, effectively erasing Halfrek from existence and preventing her from ever becoming a vengeance demon. This act has a significant impact on Anya and the other characters.
