Crossover Episodes

[Silver Roc]

Hi does anyone know where I can find a complete list of all star trek characters to appear in other trek series like Tuvok in the DS9 mirror episode and so on?

Because I like doing this sort of thing, I'll provide the details.

TNG
Encounter at Farpoint (cameo by Dr. McCoy)
Sarek (features Sarek. Duh)
Unification (Spock and Sarek)
Relics (Scotty)
Birthright, Part 1 (Dr. Bashir)
Firstborn (Quark)

DS9
Emissary (Captain Picard)
Defiant (Tom Riker)
Through the Looking Glass (Mirror Universe Tuvok)
Trials and Tribble-Ations (entire TOS cast, through stock footage with actors digitally inserted in)
Doctor Bashir, I Presume (Dr. Zimmerman and an EMH)

Voyager
Caretaker (Quark)
Death Wish (Commander Riker)
Flashback (Sulu and Rand)
Timeless (Geordi La Forge)
Pathfinder, Lifeline, Inside Man (Deanna Troi)
In addition to those previous three, Lt. Barclay also appeared in Projections, Author Author, and Endgame

Didn't Zefram Cochran come back for a scene in the Abomination?

I always thought it was a shame that we didn't get one full-blooded DS9/TNG crossover like the CSI eps down the years. Would have been excellent to have had the two crews working together fully, plus it could have brightened up TNG's dull final year.

Yes, in Broken Bow. I tried to limit my list to main characters. I made the exception with Sarek mainly because some think of him as a main character since he was in 4 out of the 6 TOS movies. I listed Rand since she appeared in the same episode as a main character.

Barclay's Voyager appearances were something I was relunctant to list, but I figured if I didn't someone else would, so I might as well list them. Besides, he was in three episodes with a main character.

Tom Riker and Dr. Zimmerman were played by the same actors as main characters, so I included them on those grounds. I can get away with it since Tom Riker was posing as Will Riker for half the episode, and and EMH appeared in the same episode as Dr. Zimmerman.
