A few faces from Star Trek: Voyager appeared on Star Trek: Deep Space Nine despite the USS Voyager being stranded in the Delta Quadrant for seven years. Star Trek: Voyager premiered in 1995 during Star Trek: Deep Space Nine season 3, and the two series ran concurrently until DS9 ended in 1999.

In a recent interview with ScreenRant, Nana Visitor posited Captain Kathryn Janeway (Kate Mulgrew) coming aboard Deep Space Nine. Unfortunately, Janeway never met Captain Benjamin Sisko (Avery Brooks) despite the USS Voyager being docked at DS9 in Star Trek: Voyager‘s series premiere.

Star Trek: Voyager also found creative ways to crossover into the Star Trek: The Next Generation movies. Robert Picardo played a different Emergency Medical Hologram, and Ethan Phillips had a holodeck cameo in Star Trek: First Contact. Admiral Janeway then ordered Captain Jean-Luc Picard (Patrick Stewart) to Romulus in Star Trek: Nemesis.

Similarly, Star Trek: Deep Space Nine managed a pair of innovative Star Trek: Voyager actor and character appearances after the lone crossover between the two series that happened in Star Trek: Voyager‘s series premiere.

Ensign Harry Kim

Star Trek: Voyager Season 1, Episode 1 – “Caretaker”

Ensign Harry Kim (Garrett Wang) was the first person from Star Trek: Voyager to officially crossover with Star Trek: Deep Space Nine. When the USS Voyager docked at DS9 before its mission to hunt Chakotay (Robert Beltran) and the Maquis, Ensign Kim spent some time in Quark’s (Armin Shimerman) Bar and met its Ferengi proprietor.

Although Harry says that Starfleet Academy warns cadets about the Ferengi, the young, fresh-faced Ensign nearly falls for a swindle by Quark. Harry wouldn’t cross over with Star Trek: Deep Space Nine again until Star Trek: Lower Decks season 5, episode 9, “Fissure Quest,” when numerous Ensign Harry Kims and one Lieutenant Harry Kim from the Multiverse come aboard the Defiant Class starship Anaximander.

Lt. Tom Paris

Star Trek: Voyager Season 1, Episode 1 – “Caretaker”

Lt. Tom Paris (Robert Duncan McNeill) became the second Star Trek: Voyager character to step aboard Deep Space Nine in “Caretaker.” Paris made a timely intervention to rescue Ensign Harry Kim, exposing Quark’s scheme to bamboozle Harry. This forged the friendship between Kim and Paris that would span Star Trek: Voyager‘s run.

Recently released from a New Zealand prison colony by Captain Janeway, Lt. Tom Paris was brought aboard the USS Voyager as an “observer” to help locate the Maquis. After becoming the USS Voyager’s helmsman, and the smarmy, unlikable Tom Paris of Star Trek: Voyager’s early years gradually became redeemed, but he didn’t return to Deep Space Nine.

Tuvok

Star Trek: Deep Space Nine Season 3, Episode 19 – “Through The Looking Glass”

Not long after Star Trek: Voyager premiered, Tuvok (Tim Russ) made a surprise cameo in Star Trek: Deep Space Nine. However, Tim Russ wasn’t playing the USS Voyager’s Security Chief, who was stranded in the Delta Quadrant. This version of Tuvok was in the Mirror Universe.

The Mirror Tuvok was part of the Terran rebellion against the Klingon/Cardassian Alliance. The Vulcan led his own rebel faction, different from Smiley O’Brien’s (Colm Meaney), who brought in Commander Sisko from Star Trek’s Prime Universe.

Tuvok is the only Star Trek: Voyager Mirror Universe doppelganger who appeared in live-action. Star Trek: Prodigy season 2, episode 14, “Cracked Mirror,” introduced the evil Mirror Universe versions of Admiral Janeway and Captain Chakotay, but in animated form.

Dr. Lewis Zimmerman

Star Trek: Deep Space Nine Season 5, Episode 16 – “Dr. Bashir, I Presume?”

Star Trek: Voyager‘s Emergency Medical Hologram was based on its creator, Dr. Lewis Zimmerman (Robert Picardo), who made a surprise appearance in Star Trek: Deep Space Nine season 5’s “Dr. Bashir, I Presume.” Zimmerman sought to base a new Long-term Medical Hologram program on Dr. Julian Bashir (Alexander Siddig), and inadvertently uncovered Bashir’s secret that he had been genetically augmented as a child.
