The Enterprise landing party beams down to an unexplored planet and discovers a species called the Phylosians — sentient, humanoid plants who can talk (through a translation device, but still). They save Sulu from an accidental poisoning and gain Kirk's trust — before a bunch of plant-based pterodactyls swoop in and make off with Mr. Spock.
The Phylosians are led by a giant man named Keniclius, who was a genetically engineered superhuman exile from the Eugenics Wars era who somehow found himself here, where he has survived for centuries by cloning himself over and over so he can eventually carry out his nonsensical mission of, I don't know — creating a master race to "keep the peace"?
"The Infinite Vulcan" is a mess of an episode with so many confusing and bizarre turns of the plot and strange motivations that I gave up and just regarded the story as a series of random acts. The crew beams back to the ship without Spock, and then beams back down in secret to try to retrieve him, and makes an alliance with the Phylosians to retrieve Spock from Keniclius' clutches before Keniclius' grand plan can be enacted. They travel through some underground tunnels before being attacked by the pterodactyls, but are able to get themselves to Keniclius' cloning room.
Much like in "Spock's Brain," Spock is required for his unique mind, and nearly loses it as a result; Keniclius clones the original Spock into a giant Spock to carry on his "master race for peace" nonsense. This puts the real Spock's life in jeopardy, but Kirk is able to talk logic to Giant Spock, who mind melds with Original Spock to restore his mind. By the end, Giant Spock still seems to be alive, which is a rather strange loose end.
"The Infinite Vulcan" was written by Walter Koenig in his sole contribution to TAS (having not been hired to reprise his role), but it suffers from a severe lack of focus, and mistakes speechifying for genuine insight. I like that the problems here are solved with dialogue rather than fighting. I just wish the dialogue made sense. Keniclius' change of heart is something that requires a single conversation, making you wonder why he spent 300 years waiting to see it through in the first place. This episode is too absurd to take itself this seriously, or too serious to be this absurd.
