Taydeus, also known as Professor Warner Thaine, was a demon who posed as a professor in an attempt to destroy The Charmed Ones.


Taydeus was an upper-level demon who had targeted women to steal their life force over the centuries.

In 2018, Taydeus disguised himself as a famous scientist and college professor named Warner Thaine who became the center of a local scandal regarding sexual harassment. A student named Angela Wu, who later became comatose, accused Warner of sexual harassment and as a result he was suspended.

Three months after Marisol Vera's death, Warner was cleared of all charges and returned to the university. The demon would target Mel Vera, in an attempt to steal her life force, but he would be vanquished by The Charmed Ones.

With his last breath, Taydeus mocks the neophyte witches and tells them that he was not the one who killed their mother. Though he was dead, his body remained and Harry Greenwood jokingly suggested they may have to crack his neck, gouge out his eyes or eat his intestine to get rid of him, before Taydeus finally exploded.


Taydeus was a cruel and sadistic demon, taking pleasure in stealing the life force of women. He has little compulsion with killing, as he attempts to do that to Cam Russo, whom he mocks by saying "he's awful".

Physical Appearance

The mortal appearance of Taydeus was of a Caucasian male with graying hair. His true form was of a frost demon whose body was covered in ice and spikes, as well having clear blue eyes.
