I'm not sure that she did come back in the ninth season (its a comic book). The only Prue that is mentioned is Phoebe's Daughter, Prue Jr.
If you would like to read more go on charmed wikia :)
The first season of Charmed was in 1998 with Shannen Doughty, Holly Marie Combs and Alyssa Milano as Prue, Piper and Phoebe Halliwell.
Well Shax killed Prue and Piper but Piper came back alive and Piper tried to bring Prue back to life but it did not work.
false Piper, Phoebe and Prue. Paige came later instead of Prue
No, but there is a spin off internet season made of series of clips from seasons 1-3 where they changed it to be Phoebe who died, not Prue. It's called "The VP's Charmed" Google it. There is probably an episode where she did dye (I don't remember) but she definitely came back to life.
I am very sorry to tell you this but there is no season 9 in charmed season 8 episode 22 all that happens is that you see piper's kids and phoebe and her boyfriend and then you see piper telling a story to some kids.
WRONG: I don't think that Shannen Doherty will ever come back because I don't think the casting crew (Pheobe, Piper,and Paige) get along with her. RIGHT: Prue Halliwell died in the Charmed series. That is the only reason that Paige Mathews, there adopted sister, came into the picture. Take it from a specialist who watches it everyday its on.
Season 3 episode 19, ''The Demon who came in from the cold''
Because the actress playing Prue, Shannon Dorthey, left the show (so the character was killed on the show), and the sister couldn't be the Power of Three without 3 sisters, so Paige came in.
While many people think Shax, a bounty of the Source, went and killed Piper, but Phoebe made a deal with the Source to rewind time and save her. He did but when the whole scence restarted, Phoebe wasn't upstairs to warn them. Shax killed both Piper, Pure, and their innocent. Leo came just in time to save Piper but not Prue hence, she died.
A new character comes on from the future and says he came to stop the demons that turn Wyatt (Piper's son) evil.
Baby Chris is Piper's second son also guy who came back from the future is in "Oh My Goddess!
it came back on thursday 1.4.2012
