Star Trek II: The Wrath of Khan introduced Lieutenant Saavik, who was the first female Vulcan Starfleet Officer seen in the franchise. Saavik was a cadet at Starfleet Academy who was stationed aboard the USS Enterprise on its training voyage. Ranked as a Lieutenant, Saavik was the Enterprise's navigator during the crisis where Khan Noonien Singh (Ricardo Montalban) stole the Genesis Device and sought revenge on Admiral James T. Kirk (William Shatner). Saavik returned in Star Trek III: The Search for Spock and Star Trek IV: The Voyage Home.
Lieutennat Valeris, Captain Spock's second Vulcan protégé, was introduced in Star Trek VI: The Undiscovered Country. Valeris served as helmsman of the USS Enterprise-A during the starship's mission to escort Klingon High Chancellor Gorkon (David Warner) to the peace confernce between the Klingon Empire and the United Federation of Planets. However, Valeris betrayed Spock and the Federation when she became part of a conspiracy to assassinate Gorkon and prevent peace.
Lt. Saavik Became Captain Of The USS Titan After The Star Trek Movies
Saavik's Last Canonical Appearance Was In Star Trek IV
Lieutenant Saavik helped Admiral Kirk and the crew of the USS Enterprise bring Spock back to Vulcan and reunite him with his katra, or Vulcan soul. Saavik then remained behind on Vulcan when Kirk, Spock, and their friends returned to Earth in Star Trek IV: The Voyage Home. However, ancillary backstory material for Star Trek: Picard season 3 revealed that Saavik became Captain of the USS Titan in the 2290s. Under Captain Saavik, the Titan even briefly served as the flagship of the Federation.
Lt. Valeris Was Imprisoned For Treason After Star Trek VI
Valeris Only Appeared In Star Trek VI
Lieutenant Valeris' fate isn't as positive as Lieutenant Saavik's in Star Trek VI: The Undiscovered Country. Despite Captain Spock's mentorship where he intended Valeris to replace him aboard the USS Enterprise, Valeris succumbed to her fears of a galaxy where the Federation and Klingons became allies. Valeris entered a conspiracy led by Klingon General Chang (Christopher Plummer) that included Starfleet's Admiral Cartwright (Brock Peters).
Aboard the Enterprise, Valeris helped engineer Chancellor Gorkon's assassination, and she worked to prevent Spock's investigation to uncover the truth, even murdering Gorkon's true murderers. However, Captain Kirk deduced Valeris' role as a conspirator and a mind meld by Spock revealed her co-conspirators. After the crew of the USS Enterprise and USS Excelsior saved the Khitomer Peace Conference and revealed the conspiracy, Valeris was taken into Federation custody.
Valeris has not reappeared canonically in Star Trek.
Star Trek has not revealed what became of the former Lieutenant Valeris, but it can be assumed she was held in a Federation prison. Valeris has not reappeared canonically in Star Trek, and Spock never mentioned her again in his subsequent appearances in Star Trek: The Next Generation or J.J. Abrams' Star Trek (2009) and Star Trek Into Darkness.
Why Spock Had 2 Vulcan Proteges (Played By 3 Actresses)
Director Nicholas Meyer Cast The Original Saavik & Valeris
Kirstie Alley played Lt. Saavik as more emotional in Star Trek II, with the unrealized idea that Saavik was half-Romulan. However, Leonard Nimoy worked with Robin Curtis to make Saavik fully Vulcan in Star Trek III and IV.
Kim Cattrall had auditioned for the role of Lt. Saavik in Star Trek II: The Wrath of Khan, and director Nicholas Meyer liked and remembered her. When Lt. Valeris was created to replace Saavik in Star Trek VI, Meyer was glad to cast Cattrall as Spock's treasonous protégé. As for Saavik, two different ideas that were not pursued were to make Saavik Admiral Kirk's love interest in Star Trek II, and for Saavik to become pregnant with Spock's baby after they shared pon farr in Star Trek III.
Will Spock's Vulcan Proteges Appear Again In Star Trek?
Strange New Worlds Could Introduce Young Saavik Or Valeris
In 2024, Robin Curtis reprised Saavik in the non-canonical short concept film 765874 - Unification.
Star Trek VI: The Undiscovered Country takes place in 2293, 33 years after Star Trek: Strange New Worlds season 3. However, it's unclear how old Lt. Valeris is. It's possible that Valeris is older than she looks, like Subcommander T'Pol (Jolene Blalock) in Star Trek: Enterprise or Lieutenant T'Lyn (Gabrielle Ruiz) in Star Trek: Lower Decks. Like Saavik, a younger Valeris could appear in Star Trek: Strange New Worlds and encounter Lieutenant Spock (Ethan Peck), planting the seed for either female Vulcan to one day become Spock's protégé in Star Trek.
