There have been numerous instances in Star Trek where characters have been duplicated: by cloning, transporter accidents, holograms, alternate universes, imposters, and so on. Which characters have met their own duplicate?

For the purposes of this question:

  • Star Trek refers to any of its television series or movies. So the Animated Series counts, but comic books do not.
  • "Met" means being in the same room (or an equivalent proximity). Seeing each other on viewscreens does not count. Simultaneously swapping places does not count.
  • "Duplicate" is another entity played by the same actor, who could be reasonably be mistaken for the original character. So Data and Lore count, but Data and Dr. Soong do not count.
  • Please identify the episode or movie.

    It's an interesting question, but how will you choose which answer to accept if they can't be comprehensive? – Gaultheria Sep 29 '18 at 3:57
  • @Gaultheria: Not all questions necessarily have a "best" answer. However, you and I and everyone else can upvote good answers. – DrSheldon Sep 29 '18 at 5:01

    The usual format for this kind of question would be for an answer to provide all the cases in one answer. – ThePopMachine Sep 29 '18 at 6:09

    Insisting that people limit themselves to a single example is contrary to the state goal of the site to have comprehensive single answers. – Valorum Sep 29 '18 at 7:53

    Voted to leave open, but as my two above neighbours pointed out, one example per answer isn't a great format. There are already six answers as of now; reading would be easier in one answer. If you're afraid of some kind of rep-gaming, Community Wiki seems like a good way to go. – Jenayah Sep 29 '18 at 11:43

William Riker met his transporter duplicate, Thomas Riker (TNG: Season 6 Episode 24, "Second Chances")


Captain Picard meets (and possibly kills) his duplicate in “Time Squared.”



Episode 21, season 2 - "Deadlock" (Star Trek": Voyager)

In fact the whole team of Voyager had their doubles in the episode, but not all of them met each other.

Fun fact: Kim was swapped with his double in the episode, which means in all the future episodes Kim is not the same Kim anymore, but it does not bother anyone.

    Note that Samantha Wildman's child also replaced the baby who died in the duplicate crew. – Foxy Sep 29 '18 at 8:41
  • Rumor has it that Captain Janeway had plans to promote the "real" Harry Kim. The imposter? Not a chance. He's a permanent ensign, no matter what. – Ham Sandwich Sep 29 '18 at 20:50

Does the Doctor from Voyager meeting his creator Dr Zimmerman also count? (Episode "Life Line" of Star Trek: Voyager)


In the original series, Captain Kirk was "split" by a transporter malfunction into two versions of himself, which met and conflicted, and eventually merged in "The Enemy Witin."


I might as well post the example I put in the question:

Data and his brother Lore (TNG: Datalore, Brothers, Descent part I and II).
