Gavin was a warlock sent back from the future to prevent a vaccine from being created. According to him, the vaccine would eliminate all warlocks.


Gavin arrived from the future to kill all people involved with the creation of the vaccine. One of his targets appeared to be a young woman named Tanya Parker, though it was later revealed to be her unborn child instead. Tanya was saved by Phoebe.

Phoebe and Piper figure out who he is while Prue finds out on her own using a truth spell. He tries to kill Prue after he told her everything. However, Piper makes it to them in time to freeze him. Eventually, Prue and Piper impale him in his third eye, destroying him. After he dies, he is sent back to the future.

Notes and Trivia[]

  • Gavin shares many similarities with the Terminator from the 1984 film. Both characters travel back in time to prevent someone from being born, in order to stop the good they can potentially do.
  • There was no entry about him in the Book of Shadows which implies that his kind of warlock, with a third eye (sub-species), doesn't exist in the timespan in which he was sent and evolves much later.
  • Gavin was never introduced by name in the episode.


Gavin appeared in a total of 1 episode throughout the course of the series.
