Star Trek The Original Series Character Crossovers

Star Trek The Savage Curtain

Kahless (Recreation)

  • Star Trek
  • Star Trek The Next Generation

Played by Robert Herron in The Original Series episode The Savage Curtain as a recreation of Kahless The Unforgettable, the first Klingon Warrior to unite the great houses, he would also return during The Next Generation, this time as a clone of the original.

Kahless is one of the most influential characters in the series, despite the original man never having appeared in a single episode, and his copies only appearing in two episodes total. His war cry ‘Today is a Good Day to Die’ has become essentially a tagline for his people and the entire first season of Discovery was for all intents and purposes an homage to his legacy.

Star Trek The Trouble With Tribbles Korax


  • Star Trek
  • Star Trek The Animated Series
  • Star Trek Deep Space Nine

Originally played by Michael Pataki in The Original Series, and later voiced by James Doohan in The Animated Series, Korax was the first officer aboard the Go’rth commanded by Koloth and was a part of the crew aboard K7 during the events of The Trouble With Tribbles, and would later return through the use of archive footage in the Deep Space Nine episode Trials and Tribble-ations.
