Shax

Shax was a powerful upper-level demon with wind-based abilities. He was best known for being one of the personal demonic assassins for The Source of All Evil who would often send him to kill countless innocents. Shax is responsible for the death of Prue Halliwell, the eldest Charmed One. He was vanquished in 2001 by the freshly reconstituted Charmed Ones, avenging their sister.

Killing Dr. Griffiths
After being assigned to kill Dr. Griffiths, Phoebe Halliwell received a premonition of his death. She and her sisters rushed to find him. As soon as they found him, he was taken to the manor. The sisters talked about how they could vanquish Shax, much to the shock of Dr. Griffiths. He believed it was a prank set up by his ex-wife. However, it was not. Shax whirled in and blasted Prue and Piper through the living room wall and into the conservatory of the house, killing Prue and fatally injuring Piper. Dr. Griffiths was stunned and asked "What are you?", Shax replied "The end" and Griffiths was subsequently blasted through the dinning room window. Shax then whirled out of the manor with a grin, slaming the door and shattering the glass.

Attempt to kill Paige Matthews
During Prue's funeral, an unknown girl named Paige came to condole Prue's death. Paige said that she used to know Prue. Suddenly, Phoebe received a premonition about the girl she has just met. Later that night, Paige was dancing with her boyfriend Shane at the P3. Paige was adopted by two mortals, without any clue of being a witch. The same night, she and Shane went to the roof of some building, embraced. Afterwards, Phoebe and Cole shimmer in, with spyglass. According to Phoebe's premonition, Paige should be attacked at this place. Almost at the same time, Shax whirls in. He hits Shane with his power, sending him flying into the vent. He's now about to blast Paige. He blasts another ball attempting to hit her, but Paige inadvertently orbs out and back in, leaving both Shax as well as Cole and Phoebe amazed.

Final Vanquish
After killing Prue and nearly killing Paige, Shax rendered another attempt to kill The Charmed Ones and destroy the Power of Three, later the night in which Phoebe and Cole would meet Paige. The two were amazed with what they have seen - her ability to orb. They tell it to Leo who cannot believe since both him and the Elders don't know about her, and can't explain why she can orb, which makes Piper go upstairs and summon Grams in the attic.

Piper asks Grams about Paige, but Grams can't tell - she is sworn to secrecy, and cannot say by who. Later, it's shown that Patty Halliwell sworn Grams to keep quiet. Patty then explains Paige's origin, saying that Paige was the product of Patty's affair with her whitelighter Sam Wilder. Shortly after, Patty and Grams leave.

As Piper, Phoebe and Leo go downstairs, they find Paige in. Piper shakes Paige's hand, and suddenly, chandelier shimmers, bathing the sisters with blue light. The Power of Three is reconstituted.

Right after new Charmed Ones are created, Shax bursts in the manor, tending to kill the sisters. Leo distracts him by jumping on his back, though Shax easily tosses him across the hall, knocking him out. In the attic, Piper and Phoebe find the vanquishing spell, and tell Paige to chant the spell along with them. The sisters recite the spell, vanquishing Shax for good and avenging Prue.
