Once in a Blue Moon


The Blue Moon Beasts are magical beasts that the Charmed Ones transformed into on the three nights of the Blue Moon.


When the Blue Moon appeared over San Francisco for a second time, which only occurs once every fifty years, it affected the Charmed Ones' powers, making them unstable and giving Phoebe violent and painful nightmares connected to her premonitions. When the blue moon appeared in the sky, they turned into wild wolf-like Beasts who attacked whitelighters and Elders, partly because of their strained relationship concerning Leo and because they felt threatened by them.

The Elders planned to assign a new whitelighter to the Charmed Ones since they suspected (correctly) that Leo was the one who killed Zola, however, they also felt that Leo was a threat to the sisters. When Leo confronts the new whitelighter Danny, he suggests that he shouldn't take on the duty. Moments after Leo left, the new whitelighter was mauled by three savage beasts.

When the Elders discover him attacked, they immediately suspect Leo, however, the Charmed ones set a trap with the Crystal Cage for the beasts with another whitelighter named Marcus as bait. Waiting for the beasts as the blue moon rises, the Charmed Ones suddenly turn into the beasts and attack the whitelighter. With his last ounce of strength before passing out, Marcus traps the sisters in the cage. The Charmed Ones wake up the next day inside the cage next to Marcus's body, realizing that Phoebe's dreams were real and that they were really the creatures, suspecting that the Blue Moon caused this to happen.

During the final night of the blue moon, the sisters were preparing to cage themselves, when Leo (being possessed by a Possessor Demon) attacks them and goes after the Elders. The Charmed Ones expel the demon out of Leo. However, the Elders not realizing this, transport him to another location. When the sisters start to protest, the blue moon rises and they attack the Elders as the Elder Odin knocks them out with one attack. The sisters try to find the demon that possessed Leo and when Odin says no because they turned into monsters. They tell him that it was only the Blue Moon that caused the change and it wouldn't happen again for another fifty years.

  • High Resistance: The ability to be highly resistant to physical and magical harm. As the beasts, the Charmed Ones were able to survive the lightning bolts thrown at them by Odin.


  • The beasts were planned to be done with costumes similar to the Wendigo, but due to the low budget, the producers had to decide on computerized images given that the transformation would have been harder with there being three of them instead of one.
