OH!CAST dives into Star Trek: The Animated Series — the psychedelic, Filmation‑powered continuation of TOS that quietly reshaped Trek canon and set the stage for everything from Star Trek 2009 to Strange New Worlds. In this animated deep dive, Cal, Rob, Eileen and Martin explore why TAS is far more influential than fans remember, and how its bold sci‑fi ideas still echo across the franchise.

We kick off with the legendary Yesteryear, the universally‑praised TAS episode that introduced Spock’s childhood, Vulcan’s desert aesthetic, and the emotional rite‑of‑passage that shaped his adult identity. The crew break down the time‑travel paradox, the Guardian of Forever callback, the pet‑loss metaphor, and the philosophical question of whether trauma is necessary for growth. We also explore how this episode directly inspired JJ Abrams’ Star Trek 2009, from young Spock’s bowl‑cut design to Vulcan’s cultural portrayal.

Next, we tackle The Counter‑Clock Incident, TAS’ mind‑bending reverse‑time adventure featuring the debut of Robert April, the Enterprise’s first captain. We discuss eternal youth, retirement ethics, mirror‑universe parallels, and how Strange New Worlds re‑canonised April decades later. Eileen digs into the gender representation of TAS, comparing Uhura’s command moments to the original pilot The Cage, and how TAS sometimes stumbled while trying to portray women in leadership.

We then explore One of Our Planets Is Missing, a standout example of TAS doing truly alien sci‑fi better than TNG’s Crystal Entity. The crew analyse the episode’s cosmic‑scale threat, the alien’s incomprehensible perspective, and how animation allowed Trek to finally portray non‑humanoid intelligence convincingly. We also look at TAS’ recurring theme of humanity being judged by higher beings — a concept that later defined Q’s trial in The Next Generation.

From there, we jump into The Slaver Weapon, a rare Kirk‑free adventure spotlighting Spock, Uhura and Sulu. We break down the introduction of the Kzinti, the episode’s pulpy sci‑fi energy, and why TAS was uniquely positioned to explore species and technologies that TOS couldn’t afford to portray. We also talk about TAS’ early version of the holodeck, the first appearance of Kirk’s middle name Tiberius, and the introduction of characters like Arex and M’Ress who later influenced modern Trek alien design.

Throughout the episode, we debate TAS’ Filmation animation style — the Scooby‑Doo corridor runs, Batman‑style music stings, psychedelic colour palettes, and the infamous repeated stock footage. Rob shares his love for the lilac Klingon tabards, Eileen praises TAS’ science‑first storytelling, and Martin confesses he struggled to connect emotionally with animated characters. We also discuss the origins of Star Trek conventions, the challenges of 1970s kids’ TV, and how TAS kept the franchise alive between TOS and the movies.
