Yama is the Gatekeeper of Del Huoy, the opening to the gates of Chinese Hell.Yama is a knighted soldier on horseback, with glowing green eyes. He seeks to capture souls, absorbing them by impaling them on his lance, and does not care whether the souls are good or evil. Yama appears on Earth after someone dies, and has a window of opportunity to capture their soul before their body is properly buried. Though Yama is a spirit, witches are able to see him. And though he belongs in a spiritual realm, he proves to be vulnerable to Piper's freezing power. Once Yama attempted to capture the soul of Mark Chao, an innocent man killed by Tony Wong to fake his death. Mark found the Charmed Ones and they helped to discover his body. When Tony died in a police shootout Mark pushed Tony's spirit into Yama but before Yama could claim Mark the Charmed Ones prevented him from doing so and teleported.
