Although Deanna Troi didn’t don any prosthetic space alien makeup in Star Trek: The Next Generation, any feature films, or elsewhere, the fact remains that, like Spock before her, the character of Deanna Troi wasn’t entirely human. The dark contact lenses on Troi’s eyes, and her mother Lwaxana Troi, were clues, but the empathic and sometimes telepathic powers of the Betazoid alien species have been a Star Trek staple for nearly 40 years since the debut of The Next Generation.
And now, in the second episode of Star Trek: Starfleet Academy, the capabilities and essence of the Betazoid people have suddenly been significantly expanded.
Mild spoilers ahead for Starfleet Academy Season 1, Episode 2, “Beta Test.”
The various mental faculties of the empathic/telepathic Betazoids have always been somewhat unclear. In the very first Next Generation episode, “Encounter at Farpoint”, Troi was fully telepathic, able to communicate with Riker (Jonathan Frakes) in his mind. Later, since it was established she was half-human, we came to understand she was only empathic, able to perceive different emotions.
But in Starfleet Academy’s “Beta Test”, Nahla Ake (Holly Hunter) refers to the Betazoid people collectively as “empathic”. We also learn that following the cataclysm of the Burn, the entire planetary system of Betazed built a “psionic wall” to safeguard its inhabitants from the perils of the rest of the galaxy, specifically the Venari Ral, an ad hoc band of pirates with Nus Braka as a member.
Not all Betazoids in “Beta Test” have the dark black eyes that Troi had in TNG; notably, regular cast member Tarmia (Zoë Steiner) has hazel eyes. But this change in eye color isn’t the only new aspect of the Betazoids. “Beta Test” suggests that Tarmia possesses very strong telepathic or psionic abilities, and the existence of the psionic wall — even though we don’t “see” it — is a major revelation for long-time Trek enthusiasts.
In DS9, TNG, and Voyager, the planet Betazed is seen briefly, notably in the humorous episode “Ménage à Troi”. But in all of the TNG-era Trek canon, we never saw a large group of Betazoids working together, using telepathic powers to protect their planet. In fact, the existence of this power is rather new, as it implies that Betazed could utilize the psionic powers of its people in ways we never envisioned.
In Starfleet Academy, the existence of the psionic wall is more of an existential question, something that represents a barrier: Will Betazed rejoin the Federation or not? But from a detailed canon perspective, it presents something else. Perhaps, all this time, the Betazoids were among the most powerful alien species in all of Star Trek. In fact, by the end of the episode, it’s evident that Tarmia alone is extremely powerful, maybe more powerful than any other telepathic or telekinetic character Star Trek has ever had.
Since The Original Series, Trek has been fixated on psionic powers, and the proof is that the first two pilots of TOS dealt with telepathy and telekinesis. And now, all the way in the 32nd century, Trek has casually put forth the idea that one very beloved alien species can use the power of their minds alone to create a barrier around their planet. It’s uncertain if Starfleet Academy will further explore this idea, but clearly, as of now, the Betazoids are among the most formidable species in the Star Trek universe.
