Star Trek The Original Series Character Crossovers
Star Trek Deep Space Nine Blood Oath Kang Kor Koloth
Kang
- Star Trek
- Star Trek Deep Space Nine
- Star Trek Voyager
Kang was played by Michael Ansara in all three series.
Koloth
- Star Trek
- Star Trek The Animated Series
- Star Trek Deep Space Nine
Koloth was originally played by William Campbell in Star Trek and Deep Space Nine, and voiced by James Doohan in The Animated Series.
Kor
- Star Trek
- Star Trek The Animated Series
- Star Trek Deep Space Nine
Kor was played by John Colicos in The Original Series and Deep Space Nine, voiced by James Doohan in The Animated Series.
Kang, Koloth and Kor were all Klingon Dahar Masters and high ranking officers in the Klingon Empire, each appeared in The Original Series, and went on to be played by the same actors in the fantastic Deep Space Nine episode Blood Oath, in which they carried out an attack on a long time rival who may have ties back to Discovery.
Koloth also appeared in the Deep Space Nine episode Trials and Tribble-ations, while Kang was in the Voyager episode Flashback along with Sulu. Kor on the other hand as the sole survivor of Blood Oath went on to do two more episodes of Deep Space Nine, The Sword of Khaless and Once More Unto the Breach.
That covers every character from The Original Series to appear in a later series, and like I said at the beginning, prolific. Next time we’ll continue forward with the characters of The Next Generation.
