  • Kirk and the crew discover a planet with intelligent plants and a mad scientist who wants to impose peace on the galaxy.

    This series was only able to hire six regular voice actors; so one of the seven regular Star Trek characters had to be left out of the show. Chekov, played by Walter Koenig, was the natural choice. He was the last of the seven to join the original show, and his part wasn't that important. But that didn't mean Koenig couldn't be part of the animated series; he served in another capacity. He was the writer for this episode. He tackles a subject matter the original series would have had difficulty bringing to life: the idea of a planet where plants have developed intelligent life. The episode moves along well and is a solid animated installment.moreless
  • In the past, an augment from the Eugenics War landed on a planet that was populated by human like plants. While there, he became their king and wants to make peace by force across the universe. Years later, the Enterprise arrives on the planet...moreless

    This was a fairly interesting episode. Walter Koenig, Chekov from the original series, wrote this particular episode. 'The Infinite Vulcan' starts off really good with Sulu being poisoned by a "mobile plant" that Sulu mistakes as friendly. The aliens themselves are pretty cool, but kind of hard to explain what they look like.The best part of the episode is at the end when Dr. Keniclius 5 makes a giant Spock clone. It is a pretty good story, especially since it was written by Koenig, that alone makes this worth watching. I'd rank this episode as above average of the personal enjoyment scale.moreless
  • Why, Gene?

    Understandably, Roddenberry wanted to keep Star Trek alive in some form, but his choice of an animated, Saturday morning cartoon was just bad. Granted, some of the story lines were intriguing, and the animation allowed for a few things the limited special effects and budget of the original series could never produce. The actors\' performances are dry and lifeless, the animation itself is very poor with lots of still shots and conversations are just photos with moving lips, and the same shot may even be seen in many different episodes. I remember this from when I was a kid, but I don\'t remember it being this bad.moreless

Trivia, Notes, Quotes and Allusions


  • TRIVIA (4)

    • Also in regard to the giant Spock, exactly how was Keniclius able to replicate a giant version of his uniform? It would have taken tons of the right fabrics to make an exact recreation.

    • The usual problems with giant-sized humanoids: as size doubles, mass squares. A giant-sized Spock or Keniclius would be too heavy for their muscles to move them.

    • So exactly how is a giant Spock going to be particularly useful in conquering the universe? Or even an army of giant Spocks? Even if you want an army of super-smart Spocks to help you, why make them giant-sized? That would seem to make them merely bigger targets.

    • After Spock is captured by Keniclius, there's a bridge shot with Spock in it before he is rescued.

  • QUOTES (3)

    • Sulu: It's a mobile plant. When it stops, its roots bore back into the ground. They're all over the place. I think it likes me.
      Kirk: We always encourage our officers to make friends with the natives.

    • Spock: I am pleasantly surprised at your capacity for deductive reasoning, Captain. When you are not being bellicose, there appears to be no end to your arsenal of formidable talents.

    • Kirk: By the way, Mr. Sulu, any chance of teaching me that body throw? Could come in handy sometime.
      Sulu: I don't know, sir. It isn't just physical, you know. You have to be inscrutable.
      Kirk: Inscrutable? Sulu, you're the most scrutable man I know.

  • NOTES (4)

    • This episode along with "More Tribbles, More Troubles" was released on The Animated Adventures of Gene Roddenberry's Star Trek: Volume 1 for VHS.

    • The budget for the series wouldn't allow them to add the Chekov character, so Walter's contribution to the series was the writing of this episode.

    • The Kzinti are mentioned in this episode. At the time this must have come as quite a shock to discerning s.f. fans, since they were never part of the Star Trek mythos. Most likely it was already known that Larry Niven was working on "The Slaver Weapon" and going to use the Kzinti, and Walter Koenig tossed it in there.

    • Walter Koenig named the Retlaw plant (which poisons and almost kills Sulu) after himself. A little wish-fulfillment, perhaps?
