"Trapped within the demon, the unfortunates are kept alive,their souls tortured for the pleasure he gets from their suffering"
"You think dying would be easier the second time around, but it sure doesn't look like it. It's useless to fight the poison. Don't you know death is just the beginning? In this case, of a lot more death. How's it feel to know that you will be responsible for the end of Whitelighters and witches alike? The end of good. Do I hear someone coming? No. But I hear someone going."
—Eames, right before killing Natalie, "Blinded by the Whitelighter"

Original Series
- The Source of All Evil is an ancient, demonic essence which rules the underworld and is the show's ultimate antagonist. The Source jumps from host to host to continue his evil and is behind most of the evils of the show, whether it be founding academies to break innocents into his minions; enacting genocide on the wizard race; or even using the four horsemen to attempt to destroy the world multiple times. In his appearance in the flesh, he makes multiple attempts to corrupt and mentally break the Charmed Ones and their allies before attempting to use the power-draining Hollow, against the wishes of his minions, despite the fact it would cause him to consume all of existence. Returning from his vanquishment by possessing Cole Turner, the Source corrupts his and Phoebe's unborn child into evil. Returning in the season 9 comics, the Source has his minions murder the innocents saved by the Charmed Ones to revive himself once more, before driving San Francisco insane and trying to wipe out the Charmed Ones once and for all. The evilest demon in existence with a rap sheet that spans millennia, the Source of All Evil truly lives up to his name.
- Barbas, the Demon of Fear, is a ferocious sadist who savors nothing so much as murdering people with their worst fears. With a legion of terrified dead behind him, Barbas was banished from the world and can only return if he kills 13 unmarried witches before the stroke of midnight on the 1,300th anniversary of banishment—Friday the 13th. Murdering multiple witches with fear, Barbas is banished by the Charmed Ones but proves incredibly tenacious. Returning numerous times, Barbas kills countless innocents with his powers and even attempts to take over the underworld to spread the terror further, his final appearance centering on his attempt to even murder kids under the Charmed Ones' protection.

For each graduate, the final step into demonhood is the murder of an innocent, often a loved one, as seen when he tries to force Prue's ex-boyfriend Tom into murdering his own mother, with a vast legacy of successful Demons for the Source's army behind him. When bested, Kellman attempts to murder Tom's mother himself out of sheer spite.
- "Size Matters": Gammill, The Collector, was once a handsome man with a fondness for kidnapping women and shrinking them before baking them in special clay to make them into figurines he adds to a macabre collection.
