Krause appeared in the very first season but only as a guest star. He was upped to series regular for the second season and that’s where he remained for the rest of the series. However, his appearances were cut short in Season 8 due to budget cuts (and fans didn’t like it!).
He has since had a number of guest roles in TV shows and done some TV movies. Some of his most notable appearances are as Bob Danton in Dark Rising: Warrior of Worlds and as Robert in Cypher. He has various projects in different levels of production.
You’ll see Krause a lot at conventions.
In the third season of the series, Phoebe got a love interest. We met the half-human, half-demon antagonist Cole, played by Julian McMahon. He would eventually choose the side of good only to end up choosing the side of evil again. Cole was written out in the 100th episode of the series but did return for the 150th episode for some closure.
McMahon has had one of the biggest careers since leaving Charmed out of all other cast members. He starred in Nip/Tuck very shortly after leaving the magical series, and was then in Hunters and Runaways.
He is most recently known for his role as Jess LaCroix, the head of the Most Wanted team in FBI: Most Wanted. McMahon left the series during the third season to pursue other projects. We’re keeping an eye on what those projects will be.
From the first season, we needed cops considering some of the crimes that would end up being committed by demons. Dorian Gregory’s Darryl Morris was one of them. He was introduced as a skeptic when it came to magic, but he eventually learned the truth about the sisters. Gregory left the series in the seventh season finale.
He has had a few small roles since then. His most notable is an episode of Agents of S.H.I.E.L.D., with his most recent project titled Twice Bitten.
