Cole Turner

Cole Turner is a fictional character on the WB television series Charmed, portrayed by series regular Julian McMahon between seasons three and five. McMahon returned for a guest appearance in the show's seventh season, for its 150th episode. Charmed is a series which focuses on three good witches, the prophesied "Charmed Ones", sisters who battle the forces of evil. Cole is an adversary-turned-ally of the sisters introduced in the third series and a love interest of main character Phoebe Halliwell, portrayed by Alyssa Milano. Like the show's main characters, Cole also possessed a number of magical abilities; the most commonly used were the power to teleport and the power to throw projective energy balls which could stun or kill.

Within the series' narrative, Cole is half-human and half-demon by blood, and better known to the demonic world for over a hundred years as the legendary demonic assassin Belthazor. Cole is dispatched by the Source of all Evil himself to kill the Charmed Ones only to fall in love with then-youngest sister Phoebe, renounce evil and become a close ally of the Charmed Ones. Though Cole eventually completely rids himself of his demonic nature, and marries Phoebe in the fourth season, he never gains the trust of new youngest sister Paige (Rose McGowan). As part of his storyline, the character later returns to evil after unwillingly becoming the new Source. As the Source, Cole is eventually vanquished by the Charmed Ones, only to come back from death itself in his attempts to win Phoebe back. By this point he is the most powerful being to ever exist. Driven insane, Cole is, through his own doing, once again killed by the sisters in the fifth season. When the character returns for a guest appearance in the seventh season, it is unclear what kind of being he is, but he states that he is caught somewhere between life and death, atoning for his sins.
