I Think Star Trek’s Enterprise Crew Are Why Klingons Abandoned Their Deadliest Weapon

Warning: SPOILERS for Star Trek: Strange New Worlds Season 4, Episode 4 - "A Case of Chiaroscuro"Star Trek: Strange New Worlds laid the groundwork for why the Klingons abandoned their deadliest weapon after Star Trek: The Original Series. Directed by Meera Menon and written by Skylar Ojeda and Dana Horgan, Star Trek: Strange New Worlds season 4, episode 4's Casablanca-style film noir strands a trio of USS Enterprise crewmembers on a planet occupied by the Klingons.

In Star Trek: Strange New Worlds season 4, episode 4, "A Case of Chiaroscuro," Commander Una Chin-Riley (Rebecca Romijn), Dr. Joseph M'Benga (Babs Olusanmokun), and Ensign Nyota Uhura (Celia Rose Gooding) found themselves undercover on Mat'Aar XII. Una posed as a Klingon collaborator named Nevette, who was secretly the leader of Mat'Aar's resistance.

The Klingons apprehended Uhura, who was personally interrogated by Commander Kor (Demore Barnes). Just as he will to Mr. Spock (Leonard Nimoy) five years later during Star Trek: The Original Series season 1's "Errand of Mercy," Kor used a fearsome Klingon device called the mind scanner on Uhura.

Theory: Uhura & Spock Beating The Mind Scanner Led Klingons To Abandon It

Commander Kor and his Klingons only use the mind scanner twice: The first time (chronologically in Star Trek's timeline) on Uhura in Star Trek: Strange New Worlds and the second time (offscreen) on Spock in Star Trek: The Original Series. In both instances, the mind scanner failed. I think this is why the Klingons ultimately gave up on the mind scanner.

Taken in order of how most Star Trek fans learned of the mind scanner, Commander Kor (John Colicos) was utterly confident of his torture device in "Errand of Mercy." Kor bragged to Captain James T. Kirk (William Shatner) how effective and potentially lethal his "mind sifter, or mind ripper" was, and that when used at maximum setting, it could turn its target into "a vegetable."

Yet, Spock withstood the mind scanner, which the Vulcan and Klingons attributed to his "mental disciplines." However, that's Spock, who possesses one of the strongest minds in Star Trek. More surprising, and arguably, more impressive, is how the young Uhura resisted the mind scanner five years earlier. Uhura beat the Klingons' weapon by focusing on truthful aspects of her cover identity.

Together, Uhura and Spock proved the mind scanner was fallible. Taking Kor at his word that the mind scanner delivered the desired results when it was used on other victims, this would explain why the Klingon governor took such pride in his torture device. Yet the only two times that Star Trek fans saw, or heard of, the mind scanner turned on Starfleet Officers, it proved useless.

The Klingon Mind Scanner Is Never Mentioned Again After Star Trek: The Original Series

Since the mind scanner is never mentioned again after Star Trek: The Original Series' "Errand of Mercy," it's safe to conjecture the Klingons gave up on it. Perhaps Commander Kor was embarrassed by the machine he took such pride in failing to break Mr. Spock, and he turned his back on it. Its previous failure against Uhura only compounds the mind scanner's disgrace.

Kor made a handful of appearances after "Errand of Mercy." The first Klingon in Star Trek returned (voiced by James Doohan) in Star Trek: The Animated Series, and in a trio of Star Trek: Deep Space Nine episodes as an aged Dahar Master in the 24th century. Yet Kor never used or spoke of the mind scanner again.

The Klingons were physically revamped in Star Trek: The Motion Picture, and Star Trek: The Next Generation fleshed out their warrior culture, which became a political minefield of intrigue, betrayals, and death. The Klingons were redefined as a race who prided themselves on their unique interpretation of honor, where dying in battle was glorious.

After Star Trek: The Next Generation evolved the Klingons, they were no longer a culture that would rely on information-extracting torture devices like the mind scanner. Klingons would likely find Kor's 23rd century pride and joy dishonorable, as 24th century Klingons no longer looked or behaved the way they did in Star Trek: The Original Series' era.

However, it is now Star Trek canon that Uhura in Star Trek: Strange New Worlds and Spock in Star Trek: The Original Series defeated the Klingons' mind scanner. It's a miserable track record for the Klingon device against the Empire's greatest adversaries. Spock and Uhura quite possibly and unknowingly compelled the Klingons to permanently retire their mind scanner.
