Sign in to your ScreenRant account 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.

What is the registry number of Captain Kirk’s original Enterprise from The Original Series? ANCC-1701-D BNX-01 CNCC-1701 DNCC-74656 ✓ Correct! NCC-1701 is the registry of Kirk’s original Constitution-class Enterprise. The “-D” suffix belongs to Picard’s Galaxy-class ship, NX-01 is Archer’s Enterprise, and NCC-74656 is Voyager. ✗ Red alert! The answer is NCC-1701. Kirk’s original Constitution-class Enterprise carried this now-legendary registry. NCC-1701-D is Picard’s Enterprise from TNG, NX-01 is Captain Archer’s, and NCC-74656 belongs to Voyager. NEXT → 02 Kirk’s most trusted officer is a half-human, half-Vulcan science officer famous for his logic and iconic salute. Who is this legendary character? AData BSpock CTuvok DSarek ✓ Correct! Mr. Spock, played by Leonard Nimoy, is the half-Vulcan science officer whose “Live long and prosper” salute became a cultural icon. His struggle between logic and emotion defines the heart of the Original Series. ✗ Red alert! The answer is Spock. Data is an android from TNG, Tuvok is Voyager’s Vulcan tactical officer, and Sarek is Spock’s Vulcan father. Only Spock is the half-human, half-Vulcan first officer of Kirk’s Enterprise. NEXT → 03 Starfleet’s most important regulation forbids interference with the natural development of alien civilizations. What is this guiding principle called? AThe Temporal Accord BGeneral Order One CThe Omega Directive DThe Prime Directive ✓ Correct! The Prime Directive (also known as General Order 1) is Starfleet’s most sacred law. It prohibits interfering with less-developed civilizations — though Kirk, Picard, and Janeway have all famously bent or broken it when lives were at stake. ✗ Red alert! The answer is the Prime Directive. While “General Order One” is technically another name for it, the Prime Directive is the universally known term. The Omega Directive and Temporal Accord are separate, more specialized Starfleet protocols. NEXT → 04 “Resistance is futile.” This chilling declaration belongs to a cybernetic collective that assimilates entire civilizations into its hive mind. What is this fearsome species called? AThe Borg BThe Dominion CThe Romulans DSpecies 8472 ✓ Correct! The Borg are Star Trek’s most terrifying villains — a hive-mind collective that forcibly assimilates species and technology. Captain Picard was famously assimilated and transformed into Locutus in the landmark TNG episode “The Best of Both Worlds.” ✗ Red alert! The answer is the Borg. The Dominion is the Gamma Quadrant empire from DS9, the Romulans are a rival empire, and Species 8472 is actually one of the few species that the Borg themselves fear. Only the Borg declare “Resistance is futile.” NEXT → 05 Captain Jean-Luc Picard commands the Enterprise-D in The Next Generation and later received his own series, Star Trek: Picard. Which acclaimed actor portrays him? AWilliam Shatner BAvery Brooks CPatrick Stewart DScott Bakula ✓ Correct! Sir Patrick Stewart brought gravitas, Shakespeare, and Earl Grey tea to the captain’s chair for seven seasons of TNG, four films, and three seasons of Star Trek: Picard. His “Make it so” is one of TV’s most iconic catchphrases. ✗ Red alert! The answer is Patrick Stewart. William Shatner plays Captain Kirk, Avery Brooks is Captain Sisko on Deep Space Nine, and Scott Bakula captains the NX-01 Enterprise. Only Sir Patrick Stewart portrays the legendary Jean-Luc Picard. NEXT → 06 Starfleet vessels travel faster than light by bending space around them using a matter-antimatter reaction. What is this propulsion system called? ATranswarp Drive BWarp Drive CSlipstream Drive DSpore Drive ✓ Correct! Warp Drive is the standard faster-than-light propulsion in Star Trek, powered by dilithium-regulated matter-antimatter reactions. Zefram Cochrane invented it in 2063, which led to humanity’s first contact with the Vulcans. ✗ Red alert! The answer is Warp Drive. Transwarp is an advanced Borg technology, Slipstream is an experimental quantum drive, and the Spore Drive uses mycelial network navigation (from Discovery). Standard Starfleet vessels use Warp Drive. NEXT → 07 At Starfleet Academy, cadets face a notorious no-win scenario designed to test their character under impossible circumstances. James Kirk is the only cadet who ever beat it — by cheating. What is this test called? AThe Prometheus Trial BThe Omega Simulation CThe Corbomite Maneuver DThe Kobayashi Maru ✓ Correct! The Kobayashi Maru is an unwinnable rescue simulation that tests how cadets handle certain death. Kirk reprogrammed it so he could win — earning a commendation for original thinking. It was memorably featured in Star Trek II: The Wrath of Khan. ✗ Red alert! The answer is the Kobayashi Maru. The Corbomite Maneuver is a TOS episode, not an Academy test. The Kobayashi Maru is the famous no-win scenario that Kirk defeated by reprogramming the simulation — because he doesn’t believe in the no-win scenario. NEXT → 08 In the widely regarded greatest Star Trek film, a genetically enhanced superhuman from Earth’s past seeks revenge against Captain Kirk. “KHAAAAN!” Who is this iconic villain? AKhan Noonien Singh BGeneral Chang CQ DGul Dukat ✓ Correct! Khan Noonien Singh, played by Ricardo Montalbán, is Star Trek’s greatest villain. First appearing in the TOS episode “Space Seed,” he returned in The Wrath of Khan (1982) for a devastating revenge plot that cost Spock his life. ✗ Red alert! The answer is Khan Noonien Singh. General Chang is a Klingon from Star Trek VI, Q is TNG’s omnipotent trickster, and Gul Dukat is DS9’s Cardassian antagonist. Only Khan inspired Kirk’s legendary scream across the cosmos. REVEAL MY SCORE → Mission Complete Your Starfleet Record / 8 Are you an Admiral — or still a cadet on deck-scrubbing duty? ↻ RE-ENGAGE 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.
