Starkiller ' s lightsabers Two lightsabers were created to serve as the weapons of Starkiller , a clone of the Sith Lord Darth Vader ' s secret apprentice . The lightsabers were given to the clone by the Dark Lord during his training on the planet Kamino , and were used during his escape attempt immediately after Vader deemed Starkiller to be another failure in a long line of imperfect clones . Specifications . Starkiller ' s dual weapons were constructed for the purpose of training Galen Marek ' s clone in lightsaber combat . They were part of a second series of lightsabers that Darth Vader bestowed to the clones who progressed far through their trials . As such , these lightsabers each contained a synthetic crystal which enabled them to produce a red blade . Their design was a modified version of the first set of lightsabers , many copies of which were used by the clones who were deemed as failures early in their training . Like their counterpart weapons , Starkiller ' s lightsabers were both based on a transparent hilt which displayed the blade ' s energy fluctuating within . The hilts featured a set of black plates ; the activator a simple red button located on a silver ring around the hilt , approximately halfway along its length . The emitters featured a slanted , wrap - around guard that was aesthetically similar to emitter shrouds , rather than the standard emitters on the first stock design . As with his clone precursors , Starkiller was programmed with the knowledge and skills of his genetic template via memory flash es . As such , he inherited the original Starkiller ' s preference for the Shien - style reversed grip , as well as the and Niman fighting styles . These combat forms ultimately enabled the clone to master the Jar ' Kai technique , of which Starkiller found both strengths and weaknesses in . On the one hand , he acknowledged that the use of dual - lightsabers increased his overall abilities as a combatant , and on the other , Jar ' Kai diminished the strength of his attacks since it prevented him from wielding a lightsaber with both hands . History . After progressing far through a series of trials , Starkiller received his red - bladed lightsabers from his Master and creator , the Sith Lord Darth Vader , in 1 BBY . One of many clones created and tested to replace the Dark Lord ' s original apprentice , Galen Marek , Starkiller ' s first task with his new weapons was to destroy a group of training droids disguised as Rebel troopers . Sparing no feelings for the Rebel Alliance that Starkiller ' s progenitor helped to forge , the clone destroyed the faux - troopers with practiced ease , only to find himself incapable of bringing his lightsabers down on a holodroid that took on the form of Captain Juno Eclipse . The failed training session , combined with the resurfaced memories of the Human woman whom Marek fell in love with , caused Starkiller to turn against his creator by escaping from Kamino , taking his lightsabers with him in the process . While traveling throughout the galaxy in an attempt to locate Eclipse , Starkiller had numerous occasions to use his dual - lightsabers in combat . On Cato Neimoidia , the clone killed scores of stormtroopers and various other types of Imperial soldiers in Tarko - se , shortly before using his lightsabers against Baron Merillion Tarko ' s Gorog . Afterward , he altered the color of the blades to blue when the Jedi General Rahm Kota presented him with two crystals — relics of the Clone Wars — to replace Starkiller ' s synthetic ones . Shortly after their alteration , Starkiller used the lightsabers against a squadron of Terror Trooper s and Terror Droid s that had infiltrated the " Salvation " , the Alliance Fleet flagship commanded by Captain Eclipse . Upon clearing the starship of the Terror units , the clone utilized his lightsabers against various Imperial soldiers , including Saber Guard smen and Sith Acolytes , during the Assault on Kamino . In Timira City , the cloning facility where Starkiller was created , his lightsabers left a massacre in their wake ; much of the Imperial garrison was destroyed by the clone as he infiltrated the inner workings of Timira City . Before engaging Darth Vader in a lightsaber duel , Starkiller was forced to use his lightsabers against a group of aberrant clones , all of whom originated from Galen Marek ' s genetic material as well . When Vader threatened to strangle Juno Eclipse to death via the Force , Starkiller discarded his weapons as a gesture of submission . Eclipse discreetly retrieved one of the lightsabers and attempted to assassinate the Sith Lord , damaging the control panel on Vader ' s armor in the process . Vader separated the lightsaber from Eclipse with a powerful Force Push in retaliation . Reclaiming both lightsabers through telekinesis , Starkiller was driven into a state of rage by Vader ' s attack on Eclipse . In the final portion of their duel , Vader utilized a Force blast to disarm Starkiller , which completely destroyed both lightsabers . Behind the scenes . In the novelization , which is the most canonically relevant source involving the weapons , both lightsabers are destroyed in the Assault on Kamino after Vader Force blasts them from Starkiller ' s hands and they shatter . In the and , however , Starkiller ' s lightsabers are still intact at the end of the battle .
