— An explanation of the Harbinger

The Harbinger of Hell is a demon that attacked a custodian at Hilltowne and later possessed Angela Wu. Its presence begins the third part of the prophecy that predicts the Apocalypse.


After The Charmed Ones' accepted their destiny, The Harbinger emerged in its primordial form and attacked a custodian in the lab at Hilltowne University. It would later make its way to find Angela Wu and use her as a vessel. It then began preyed upon virgins on campus, killing Cameron Russo, a student named Penelope, and a nun in the university ministry. She started targeting Macy Vaughn at the Halloween party, only to be knocked out by Mel Vera's Sonic Boom Spell and contained in the attic of Vera Manor.

As The Harbinger grew more powerful, the Elder Charity Callahan ordered The Charmed Ones to slay the demon under the full moon, as the demon will come to full strength by then. Mel, however, wanted to save the host, and together with her sisters, devised a plan to exorcise the demon, with a hidden spell written by their mother. With the spell, Harry Greenwood and Charity's assistance, and Angela's own fighting strength, they manage to extract The Harbinger and trap it in a paint can. Charity was returning home with the trapped Harbinger when a mysterious man showed up and compelled her to switch cans with him.


The Harbinger is a sadistic demon, taking pleasure in frightening The Charmed Ones and gloating about unleashing death and destruction upon the world.

Physical Appearance

The Harbinger's primordial form is that of a black living goo. While possessing Angela, it transformed her body, making her look like a decaying zombie with gray skin and wild hair. From time to time, a red energy would pulsate from the cracks of her skin.
