The Power of Four



The Power of Four was only mentioned once in the series in Season 6 in the episode It's a Bad, Bad, Bad, Bad World, when in an alternate world good Phoebe and good Paige team up with evil Phoebe and evil Paige in order to stop Gideon from killing Wyatt Halliwell.

The Power of Four was mentioned again in Season 9 comic books: The Heavens Can Wait, Family Shatters, and [http://charmed.wikia.com/wiki/Four%27s_Company Four's Company. ]Prue Halliwell finally returns from the dead and is reunited with her three sisters. However, the existence of The Power of Four is tested, resulting in The Charmed Ones stripping Prue's powers.

The Power of Four Spell
The sisters and their parallel selves create the following spell, invoking the Power of Four to destroy Gideon.


 * We call upon the Ancient Lore
 * To punish with the Power of Four,
 * Strike down this threat from both there and here,
 * Make him suffer, then disappear.

Trivia

 * In the Season 9 comic books, The Heavens Can Wait, Family Shatters, and Four's Company, it is stated that The Power of Four cannot exist. Melinda Warren didn't forsee a Power of Four. Prue and Paige share one of Melinda's powers. Piper and Phoebe have the other two. If the four Halliwell sisters were ever to be together, it would not make them stronger, but it would weaken the power of The Charmed Ones.
 * This is also a concept created by fans of Charmed, hoping that Shannen Doherty would reprise her role of Prue Halliwell. The Power of Four would be stronger and far greater than The Power of Three due to the Halliwell's half-sister Paige Matthews.
