The Times Star Trek Stars Appeared On Stargate

The Stargate SG-1 episode “Watergate” featured an appearance by Marina Sirtis, who played Deanna Troi on Star Trek: The Next Generation. In the episode, Stargate Command discovers that Russia has obtained the Stargate from Thor’s crashed ship. But the gate refuses to close, meaning the American gate can’t operate. 

Sirtis plays Dr. Svetlana Markov, who requests the SG-1 team to investigate the stuck Russian Stargate. It’s a treat for TNG fans, who get to see a different, less empathetic side of Sirtis as the Russian intelligence officer. The adventure leads members of the SG-1 team on an underwater quest on an alien planet that isn’t quite what it seems.

Armin Shimerman, Star Trek: Deep Space Nine’s scheming Ferengi bartender Quark, appeared in the Stargate SG-1 episode “The Nox.” This episode sees the SG-1 team traveling to the planet Gaia, where they hope to nab a creature that is supposedly able to become invisible in their quest to produce more advanced tech.

But Apophis finds them there, and they are all killed, only to be brought back to life by a race known as the Nox, who otherwise refuse to get involved in the team’s mission.

Shimmerman appears as Anteaus, one of the Nox who returns the SG-1 team to life.

Not wanting to play favorites, Stargate SG-1 also featured Rene Auberjonois, who played Star Trek: Deep Space Nine’s Security Chief Odo, Quark’s chief rival and arguably best friend. The episode “The Other Side” features the Eurondans, an alien race with human ancestry who get in touch with Earth to ask for their help in ending a war that has lasted for generations.

Their lack of transparency, including obfuscation regarding their enemy, the “Breeders,” raises the suspicions of Daniel Jackson. Auberjonois appears in the episode as the Eurondan Alar, whose father had planned to eradicate the Breeders and who sought to fulfill his father’s vision.

Dwight Schultz played the socially awkward but brilliant fan-favorite character Lt. Barclay in Star Trek: The Next Generation and Star Trek: Voyager and was featured in the Stargate SG-1 episode “The Gamekeeper.”

The episode features a mission to P7J-989, where the SG-1 team is trapped in pods that place them in virtual reality games that are not at all fun. Forced to repeatedly relive painful memories, Jack, Teal’c, Daniel, and Sam are all trapped in the pods and in their own minds Shultz gives a marvelously sinister performance as the Keeper, who tends to the pods and keeps the planet’s inhabitants locked inside them.

John Billingsly, who played the eccentric and wildly curious Dr. Phlox on Star Trek: Enterprise, appeared in the Stargate SG-1 episode “The Other Guys.” In the episode, The Goa’uld Khonsu sends his Jaffa to capture the SG-1 team after discovering their location. Dr. Jay Felger, a fan of the SG-1 team, then becomes their only hope for rescue, but his mission is soon compromised. 

Billingsly plays Dr. Simon Coombs, a friend of Felger’s, whom Felger recruits to aid him in his quest. There is a contentious and comical exchange between the two scientists during which they argue over whether Coombs would dress as a Klingon or a Vulcan at a Star Trek convention, and Coombs chides Felgers for not worshiping “at the altar of Roddenberry.”

John de Lancie originated the godlike, mischievous Q on Star Trek: The Next Generation and has gone on to reprise the role in four other Trek series. He appeared in five episodes of  Stargate SG-1: “Ascension,” “The Fifth Man,” “Desperate Measure,” “48 Hours,” and “Prometheus.” His character, Colonel Frank Simmons, is a member of the NID (National Intelligence Department.

Though his colleague Colonel Harold Maybourne, who occasionally offered assistance to Stargate Command, Simmons was intent on causing trouble for the SGC and was later inhabited by a Goa’uld. Across the course of his episodes, de Lancie built Simmons as a multi-layered, if persistently devious, character.
