10 Essential Star Trek: The Animated Series Episodes You Must See

There are endless reasons to watch The Infinite Vulcan. Firstly, Walter Koenig missed out on a part in the cartoon capers for 'budgetary reasons'. Nichelle Nichols and George Takei very nearly didn't make the cut either, but for some 'I'll quit if you don't' persuasion on the part of Leonard Nimoy. There is no Chekov in The Animated Series then, but, as some recompense, the man behind the character got to pen an episode, this episode, marking the beginning of his writing career. Not only that, but Koenig turned in a rather innovative script.

The Infinite Vulcan introduces us to the Phylosians, an intelligent, and highly advanced, alien race "of botanical origin." It also adeptly adds to the history of the Eugenics Wars. No one can argue that the Phylosians aren't canon either as they were given a mention in Lower Decks. A member of the species ("a nice plant person") was serving aboard the Cerritos in 2380, narrowly avoiding being set up on a date with Boimler.

Secondly, and what in the name of Stavos Keniclius Five… it's Spock Two!

If the thought of seeing a humongous version of everyone's favourite logician doesn't persuade you to give The Infinite Vulcan a watch, nothing will. Plus, you'll finally understand why the Collector's Guild was hanging on to a massive skeleton in Starfleet rags.
