In the episode "Phases" Oz learns he has become a werewolf, turning into a monster on the three nights around a full moon, having been bitten on his finger by his cousin Jordy. On his third night as a wolf, Oz is nearly killed by werewolf hunter Gib Cain for his pelt, but is saved by Buffy and the Scooby Gang, with whose help he quickly finds a way to minimize the danger posed by the wolf: he locks himself into a cage for the appropriate nights, watched over by the Scoobies in shifts. The revelation that Oz is a werewolf does not dissuade Willow from dating him, and they become a couple.
