The warlocks, Rex Buckland and Hannah Webster, were working for the Source to obtain the Charmed Ones' powers. When their plan failed due to Leo, and Piper and Prue made Hannah kill Rex, Hannah was vanquished by the Source for her failure.
Later, the demons Inspector Rodriguez and Tempus worked together to kill the Charmed Ones on behalf of the Source, Tempus turning time back in order to give Rodriguez an advantage over the Charmed Ones. This resulted in the death of Andy Trudeau, but the Charmed Ones were able to defeat Tempus, and Rodriguez was vanquished by Prue.
The demon Litvack directly served the Source, but was vanquished by Bane.
Near the end of the season, the Infernal Council sent a Dragon Warlock and a Genie to kill the Charmed Ones, although this failed.
The Source was more directly involved in Season 3, though he didn't physically appear until the season finale. He sent the Triad after the Charmed Ones, along with half-demon Cole Turner/Balthazar. However, Cole fell in love with Phoebe, turned good, and killed the Triad, prompting the Source to put a bounty on his head.
When the Charmed Ones' fight with Shax exposed both witches and demons, Cole convinced the Source to get Tempus to turn time back and prevent this from happening. However, the Source set it so that Phoebe would not be in the room during Shax's attack, resulting in Shax killing Prue.
The Source sent numerous demons after the Charmed Ones when Prue was replaced by the Halliwells' younger half-sister Paige.
The Charmed Ones caught up with the Source later and eventually duked it out with him in vengeance for him killing Prue, their sister. When the Seer, an upper-level demon prophetess, had a vision of the Charmed Ones vanquishing the Source with a trap, the Source obtained the Hollow, which was sealed away by an agreement between good and evil due to the danger of its power. The Source sent demons to use the Hollow and absorb Piper and Paige's powers, which were given to him when the demons were vanquished. However, the Seer foresaw the complete destruction of both sides due to the Hollow, and when the Source refused to seal the Hollow away again, the Seer turned to Cole and gave him the Hollow. Cole took one of the Source's fireballs for Phoebe, absorbing his power, and then the Charmed Ones used a magic spell invoking the power of their ancestors to destroy the Source.
After the Source's death, his dark powers remained inside Cole, his essence filling the void left by Belthazor (Cole's demon half had been vanquished by the fiancee of one of his victims). Cole's new demon half became the next Source, which spoke as a separate entity from Cole and eventually took over. As the Source, Cole married Phoebe in a black magic wedding in the Underworld, and attempted to poison Phoebe as vengeance, but the Charmed Ones came to Phoebe's aid and saved her, making her realize her husband was the Source. So Cole was lured into the same trap the Source had been vanquished previously and was destroyed.
Again, his essence lived on inside Cole and Phoebe's unborn demon child, the Source's Heir, and then the Seer encased the Source's Heir, and therefore the Source's essence, in herself, effectively becoming the new Source. The Seer reigned for a short time as the Source, but the Charmed Ones goaded her into tapping into her full power. The Seer did so and she self-destructed, unable to contain the power. The Source was then defeated for good, and the Infernal Council, Dark Priest, and Source's Heir were destroyed along with her. With no one else containing the Source's power, the Source was defeated for good.
The original half-faced Source was briefly resurrected by a Possessor Demon, but was re-killed when Piper vanquished the demon with Molecular Combustion.
Powers and Abilities
As the ruler of the Underworld and all that's evil, The Source is one of the most powerful magical beings in the series, and one of the Charmed Ones' greatest enemies. He has displayed a multitude of powers, more than any other demon in the series. Notable instances of his great powers are when he delayed Cole's death so that Phoebe could see him die, and by blocking Phoebe's premonitions about Cole for months. He is extremely difficult to truly vanquish due his existence as an essence of evil, even surviving being destroyed by the Power of Three on more than one occasion. After being reborn as a Golem, the Source's already immense powers grow even further due to his powerful new body, and he could only truly be vanquished when the sisters attacked him with the Excalibur, a potion brewed with the power of the entire good Magical Community and a more powerful version of the Power of Three spell.
Aside from his powers, the Source is an intelligent and cunning demon, having ruled the Underworld for centuries and dealing with all kinds of threats and concealing his true nature to other demons. He also has an understanding of the human nature and has exploited the sisters' bonds, their desires on a peaceful life and their calling to protect the innocents to his advantage on more than one occasion.
