This question already has an answer here:

Is there any actor who has played, in different Star Trek episodes, both a Starfleet crewmember (of the Enterprise, Voyager, etc.) and one of the alien strangers encountered by the crew?


Clarifications:

  • All series (TOS, TNG, DS9, etc.), plus the stand-alone films, are included in the scope of this question. (I'd be most interested in an actor who's appeared in both these roles in the same series, but also in whether anyone's been e.g. a crewmember in TOS and an alien in TNG.)
  • Neither of the roles in question needs to be a recurring role; either or both could be a one-off appearance.
  • The crewmember role needs to be that of one of the primary vessels (the Enterprise, the DS9 space station, etc.)

We're looking for long answers that provide some explanation and context. Don't just give a one-line answer; explain why your answer is right, ideally with citations. Answers that don't include explanations may be removed.

    Almost every member of the cast of DS9 (as well as Captain Picard) played a wormhole alien at some point. This might be outside the spirit of the question though. – Bamboo Nov 18 '15 at 2:32
  • Having seen a few of the answers, I'd now like to specify that the crewmember must be human. But it'd be bad form to make an edit that invalidates existing answers, so I think I'll have to leave it... – Rand al'Thor Nov 18 '15 at 10:35
  • I was thinking about pretty much everyone in DS9's "Far Beyond the Stars", but unfortunately that doesn't fit the "alien strangers encountered by the crew" condition. We see the regular crew as humans, not aliens, and I think even the "encountered by the crew" part would be a bit of a stretch. – Hilbert Nov 18 '15 at 11:35
  • @randal'thor : ThePopMachine makes a point. This question is technically a subset of other similar questions, and some of the answers here (including the highest-rated one) are answers to previous questions (and one litmus test for "dupe" is whether another question has the same answer)... – Praxis Nov 19 '15 at 7:07

Tim Russ

played the Vulcan security officer on Voyager and also a Klingon named T'Kar on DS9

enter image description here enter image description here

He also played a human crewmember on the Enterprise-B, which fulfills OP's comment that he wished it was human, but he wasn't going to change the question.

  • Added this in case you think Worf and Worf's grandfather of the same species played by the same actor is a loophole – ThePopMachine Nov 18 '15 at 2:17

    He also played a (seemingly) human in Starship Mine S06E18 – Derek Nov 18 '15 at 2:24
  • He also played a (different) human crew member on the Enterprise-B during Star Trek: Generations – Derek Nov 18 '15 at 2:27

    I'm pretty sure I also remember Picard beating him up when he's a terrorist or something, I want to say they ran away from a Barium scan...and I just now remembered that I'm pretty sure the episode was called "starship mine"...or something close to that – VapedCrusader Nov 18 '15 at 5:19

    @VapedCrusader, uh Derek already said that. And a barium scan is something totally different than a baryon sweep. <chuckle> – ThePopMachine Nov 18 '15 at 5:29

Patricia Tallman

Played the following enterprise/starfleet crewmembers:

Enterprise-D Officer, TNG: "Power Play" Enterprise-D Officer, Generations Define weapons officer, DS9: "The Way of the Warrior"

In order she is portraying:

  • Enterprise-D Officer, TNG episode "Power Play"
  • Enterprise-D Officer, Star Trek: Generations
  • Defiant Weapons Officer, DS9 episode, "The Way of the Warrior"

She also played the following aliens:

Starship Mine Nima, DS9: "Battle Lines" Alien impersonating a romulan, TNG: "Timescape" Taresian, VOY: "Favorite Son"

In order these are:

    Why the downvote? Have I done something wrong with this answer? – Zachary Zimmer Nov 18 '15 at 3:48
  • 2
    Don't let it get you down. It just happens. I can't speak for the downvoter, but I personally believe that if we don't interpret the question to mean a main castmember, then the question essentially is covered by this question. Hence not as interesting an answer as Tim Russ. But that's just me. – ThePopMachine Nov 18 '15 at 4:01
  • 1
    @ThePopMachine Ok. I thought I'd done something wrong. Also, the question specifically states "starfleet crewmember" rather than "bridge officer" or "regular" or something else. One of the Tallman roles is weapons officer on the defiant, which is certainly not a regular, but is more than an extra seen in the background. – Zachary Zimmer Nov 18 '15 at 4:06

    I agree, this is a valid answer pending any clarification. Downvotes are a normal part of life, especially on a question with lots of answers. I hope you'll have fun participating here! Welcome to SFF.SE! – ThePopMachine Nov 18 '15 at 4:12

    In case anyone is thinking "she looks familiar", she was Lyta Alexander on B5. – Rob Church Nov 18 '15 at 10:12

Michelle Forbes

Played Ro Laren of the Enterprise (8 appearances in Seasons 5-7):

Ro Laren

And played Dara, an alien from Kaelon II, daughter Doctor Timicin in the TNG Episode, "Half a Life."

Dara

Both of these roles are in the same series, TNG.

    Great answer. :-) – Praxis Nov 18 '15 at 4:38

Michael Dorn

The actor played Lt./Cmdr. Worf and Col. Worf, who ate are different characters, the first being an Enterprise crewmember and the second being an encountered Klingon.

23

Aron Eisenberg

Played ensign Nog, here standing up to General Martok while serving as a security officer on DS9: enter image description here

And here playing Karden, a Kazon youth in Voyage episode "Initiations" enter image description here

  • Didn't he also play a human in "Sanctuary"? Not a big role but I'd say it qualifies as "alien" given that his crew member character was Ferengi. – mu is too short Nov 18 '15 at 6:15

Denise Crosby

(Wikipedia article) (Memory-Alpha Article)

I am surprised this wasn't added to this list, and though it's not a super long answer, it appears to be valid by the constraints on the question.

Spoilers of certain episode plot lines exist further on, abort now if you wish to avoid them!

FEDERATION:

Lieutenant Natasha ("Tasha") Yar, who was security chief (and tactical officer) on the Enterprise D before Worf was assigned as chief of security / tactical after her death in the series. She was a big part of the USS Enterprise-D's crew as chief of security and tactical officer.

Denise Crosby, as Lieutenant Natasha "Tasha" Yar

And this is a short list of aliens she played, but she played a well known nemesis of the Enterprise and the Federation...

ALIEN:

If you didn't know this before, Denise also played Romulan Commander Sela, a well known Romulan enemy.

Denise Crosby, as Commander Sela

Sela was behind the following major events, to my best recollection (this is not, however, a complete list of her appearances):

  • Geordi LaForge's abduction and brainwashing (in which he tried to kill a Klingon official, during TNG 4x24, "The Mind's Eye"), and
  • providing aid, supplies, military assistance, and other resources to the Duras family during the Klingon Civil War (TNG 4x26 and 5x01, "Redemption", parts 1 and 2).
  • She was behind the plot to send Vulcan ships filled with Romulan troops to Vulcan, during "Unification" part 2 (TNG 5x08), in an attempt to invade Vulcan under the pretense of 'reunification' of the Vulcan and Romulan peoples.

All images listed here are from Memory Alpha's page on Denise Crosby, though the system here on StackExchange forced an Imgur upload.

I was surprised not to see

Suzie Plakson

on the list.

In The Next Generation, she played Lt. Selar in The Schizoid Man Lt. Selar
as well as K'Ehleyr (with whom Worf fathered Alexander) in The Emissary and Reunion. K'Ehleyr

She would later play the Female Q in the Voyager episode The Q and the Grey Female Q
as well as the Andorian Tarah in the Enterprise episode Cease Fire: Tarah

Not as high of a count as others, but Selar and K'Ehleyr meet the requirements of the question (without the constraint added in a comment) in a single season of the same show.

13

Rene Auberjonois

played Odo on DS9 and a Kantare named Ezral on Enterprise

I would also note that during seasons 4 and 5, Odo is human after being transformed by the link. (This is not required by OP, but he stated he would have added the restriction except there were already so many answers.)

From "Broken Link"

BASHIR: Physiologically, you're completely human.

  • 1
    I add this because it fits the letter of "encountered alien". I'd also add Odo was human for two seasons, although that's not required by the question. – ThePopMachine Nov 18 '15 at 2:25
  • He also played Colonel West in ST VI: The Undiscovered Country. – Brandon Dybala Nov 18 '15 at 19:07
  • @BrandonDybala: Yes, but not an alien. – ThePopMachine Nov 18 '15 at 19:10
  • Not sure solid is necessarily human – JNF Nov 19 '15 at 10:15
  • @JNF, see edit. It can't get more clear than such a plain statement by the CMO right after examining him. – ThePopMachine Nov 19 '15 at 13:39

Stewart Moss (TOS)

Stewart Moss appeared in the TOS episode The Naked Time as Starfleet lieutenant junior grade Joe Tormolen, and later in the TOS episode By Any Other Name as Kelvan alien Hanar.

Moss confirmed in an interview that he is the only TOS actor satisfying the OP's criteria:

My being cast in “By Any Other Name” happened because the director of “The Naked Time,” Marc Daniels, asked for me. As it turned out I was the only actor in The Original Series to guest star as both a crewmember and an alien. The guest cast on “By Any Other Name” was excellent. It included Warren Stevens, a charter member of the Actor’s Studio, and two lovely ladies, Barbara Bouchet and Julie Cobb.

  • Funny he took a different name in that episode. – CandiedMango Nov 18 '15 at 2:14

This may or may not count since it is pre-Federation but Vaughn Armstrong played Admiral Forrest in the "normal" universe and Captain Forrest in the mirror universe (where he certainly was an Enterprise crew member) in ST:ENT as well as various aliens in various series including Klingons, Cardassians, Vidiians, and Romulans:

  • Korris (Klingon) in "Heart of Glory" (TNG) and "Shades of Gray" (TNG).
  • Danar (Cardassian) in "Past Prologue" (DS9).
  • Telek R'Mor (Romulan) in "Eye of the Needle" (VOY).
  • Seskal (Cardassian) in "When It Rains..." (DS9) and "The Dogs of War" (DS9).
  • Lansor (unknown species) in "Survival Instinct" (VOY).
  • Unnamed Captain (Vidiian) in "Fury" (VOY).
  • Unnamed Alpha (Hirogen) in "Flesh and Blood" (VOY).
  • Korath (Klingon) in "Endgame" (VOY).
  • Unnamed Captain (Klingon) in "Sleeping Dogs" (ENT).
  • Unnamed Captain (Kreetassan) in "Vox Sola" (ENT) and "A Night in Sickbay" (ENT).

The last two are interesting because they were in the same series as his human characters.

I think James Doohan also deserves a mention. He played Scotty but he also did voice work for Sargon (an alien with no body in "Return to Tomorrow"), the M5 computer ("The Ultimate Computer"), The Oracle of the People ("For the World is Hollow and I Have Touched the Sky"), and various aliens in the animated series.

Majel Barrett would also qualify. She played Nurse Chapel in TOS (a crew member) and Lwaxana Troi (an alien) in TNG and DS9.

  • Not an Enterprise, DS9, or Voyager crewmember – ThePopMachine Nov 18 '15 at 3:47
  • @ThePopMachine: Unless you count the mirror universe where Forrest was on the Enterprise. – mu is too short Nov 18 '15 at 5:54
  • @HagenvonEitzen: But she was never crew, just an occasional guest. – mu is too short Nov 18 '15 at 17:26
  • @muistooshort Argh, some shortcut in my brain thought this was about Deanna – Hagen von Eitzen Nov 18 '15 at 18:25

Brent Spiner

Brent Spiner played the role of Lt Cdr Data in TNG as well as the role of his brother Lore (who could be considered an alien). He also played B-4 in Star Trek: Nemesis.

He also played Dr. Noonian Soong on several episodes of TNG. He's human, but lives off earth, so he's an alien by citizenship maybe?

For completeness, he also played Arik Soong on Enterprise, but that was a human on earth, so I guess that doesn't equate to an alien.

Ethan Phillips https://en.wikipedia.org/wiki/Ethan_Phillips

He played Neelix and several Ferengi

  • And which one of these is a "Starfleet crewmember", as requested by the OP? – O. R. Mapper Nov 19 '15 at 11:38
  • 1
    @O.R.Mapper, Neelix was a crew member (Morale Officer) and honorary Starfleet member, as were other conscripted officers such as Seven of Nine and the Maquis. – Josh Nov 19 '15 at 16:53
  • We won't hold any of these roles against him. – Nate Watson Nov 20 '15 at 15:36

Majel Barrett-Roddenberry

Majel Barrett-Roddenberry payed Nurse Christine Chapel and and a ailuroid communications officer named M'Ress in TOS and Lwaxana Troi on Star Trek: TNG and DS9.

As an aside she is also the regular voice of the onboard computers of Federation starships

Mark Lenard played the first Romulan commander seen on screen during "Balance of Terror" in TOS; he later played Spock's father Sarek in the series and movies as well as during TNG. He also played the Commander of the Amar in Star Trek The Motion Picture

James Horan played Dr. Jo'Bril in the TNG episode Suspicions (S06E22); he later played Lieutenant Barnaby in Descent (S07E01)

  • 2
    Mark Lenard also played a Klingon in "Star Trek The Motion Picture". Of course, none of those appearances are crew members. – mu is too short Nov 18 '15 at 6:04

J.G. Hertzler

Well, to be honest, kind of. Depends of what you define a crew member of the main vessel for DS9. As his main character General Martok he is stationed on DS9 for quite some time. He was one of my favourite actors to spot again and again in Star Trek (and because he was missing here, I just made an account for this answer).

Warning! Spoilers might be contained in this post!

  • General Martok (part of the combined Federation/Klingon/Romulan alliance with their main counsel on DS9)
  • Martok's Changeling double
  • A different Changeling Laas (billed as Garman Hertzler)
  • A Worm Hole Alien (aka Prophet)
  • A Vulcan Captain of a Federation ship
  • A Human artist in DS9: "Far Beyond the Stars"
  • Some Holo Suit guy
  • A Hirogen fighter in Voyager
  • Kolos, a Klingon in ENT
  • A different Klingon in ENT

see J.G. Hertzler in MA for details

I'd love to also add Jeffrey Combs, but that is stretching "main crew member" too far.

If you think Leonard Nimoy as a valid answer because of Evil Spock, you could count just about every member of DS9's main crew, as most of them have played counterparts in that universe as well (also most have played a worm hole alien in that series).

I'm not sure if this fits the requirements but Diana Muldaur was Doctor Katherine Pulaski on TNG for the second season.

enter image description here

In the TOS episode Is There in Truth No Beauty?, she also played hitchhiking telepathic doctor Miranda Jones that the Enterprise picked up. She was escorting the Medusan Ambassador Kollos. Technically she was human though she never visited earth - she was "alien" to the crew.

enter image description here

She was also crew member Ann Mulhall in the TOS episode Return to Tomorrow where she was "possessed" by an alien entity who used her body. Again, this also may not fit exactly.

enter image description here

Yes !

This question immediately made me think about Quark (played by Armin Shimerman) ! The ferengi on DS9. He was first encountered in TNG and played another ferengi called Letek (Episode "The Last Outpost") !

  • Letek

    Letek

  • Quark
    Quark

  • Armin Shimerman
    Armin Shimerman

(PS. Maybe this is not exactly a crewmember but he was a member of the main cast and worth mentioning in my opinion)

Leonard Nimoy

Leonard Nimoy played First Officer Spock during the original series and several films. In the TOS episode "Mirror, Mirror", he played Goateed Spock, first officer of the ISS Enterprise of the Terran Empire.

Goateed Spock
