Troxa was a demon featured in Season 3 of Charmed. He was one of the demons that the Triad sent to kill The Charmed Ones, Prue, Piper, and Phoebe Halliwell after Belthazor (Cole Turner's demon alter-ego) failed to eliminate them. However, Cole found Troxa to be a rival and tricked him into going into Halliwell Manor by enticing him to steal the Witches' Book of Shadows
Prue captured Troxa and tortured him for informaton on why the Triad was trying to kill them. The Demon revealed the identity of the demon that was trying to kill them, Belthazor, but as he did so, the Triad vanquished Troxa. However, Phoebe and Prue were able to identify Belthazor as the demon they caught trying to steal the Book of Shadows when they were helping Kate and the fairies a week prior. It would ultimately lead them to learning Belthazor's identity as Cole Turner.
