Starkiller (Destiny)

Starkiller, initially known as simply the Dark Apprentice, was a clone of, the former Sith apprentice of. Created by Vader in an attempt to create a perfect, obedient replica of Marek, Starkiller continued his template's role as Vader's secret apprentice in his bid to one day overthrow Emperor. However, early on in the Galactic Civil War Starkiller was lost and presumed dead by Vader, who instead shifted his focus on, his biological son. Unbeknownst to Vader, Starkiller had ended up in the Sith Order of Darth Vorath.

The Dark Apprentice
The Dark Apprentice was created by as a perfect clone of, Vader's former secret apprentice who had turned against him and perished on the. Unlike previous attempts, the Dark Apprentice was able to overcome Marek's weaknesses, such as his love for.

Shortly after his creation, the Dark Apprentice and his master set up a trap for of Marek on Kamino, which Vader planned to use as a test for the Dark Apprentice. When Vader allowed himself to be defeated by the other Starkiller clone, a cloaked Dark Apprentice stepped in and killed his duplicate before he could kill Vader. After swiftly executing and the remaining rebel forces, Vader deemed the Apprentice to have successfully passed the test and properly named him Starkiller. He then sent his secret apprentice to track down Rebel forces scattered across the galaxy and eliminate them.

Growing wind of Vader's transgressions however, Emperor decided to send an operative of his own to track down Starkiller and eliminate him. Coming into conflict with the Emperor's Hand on an Outer Rim world, Starkiller was brutally defeated by the Dark Side Adept and left in critical condition. Upon learning of a Rebel presence on said world, Kogo deviated from his task and left Starkiller for dead. Minutes later, the clone of Galen Marek was rescued at the last minute by a cloaked figure, who whisked him away to a remote world in Wild Space.

Vorath's Sith
Upon being brought to Sed'tral, Starkiller was revived and introduced to Darth Vorath, an ancient Sith Lord working under Vader and Palpatine's notice. Fabricating a story that Vader had deliberately sent him to his death, Vorath was able to convince Starkiller to join his order, promising him a place at his side once Palpatine and Vader had been removed. As Vorath's operative, Starkiller performed a series of tasks for the Dark Lord of the Sith, many which involved eliminating Imperial targets that could have potentially pose a threat to Vorath's Order.

Seven years after the Battle of Endor, which saw to the deaths of Darth Vader and Emperor Palpatine, Starkiller was given the task of luring Toah Jarsan to Vorath, as the Sith Lord had been led to believe Jarsan was a descendant of his hated rival. While Jarsan managed to escape, Vorath nonetheless acknowledged Starkiller's prowess and bestowed onto him the title of Sith Lord, naming him Darth Stalker.

Fourteen years later, Darth Stalker served as a military leader among the Imperial forces during their war against the New Republic, leading an assault on Dantooine midway into the conflict. Not long afterwards, Stalker led his forces on Borosk and came into conflict with the Jedi Knight and his apprentice. During the resulting battle, Stalker was severely wounded by the Jedi and left for dead once more as the Empire was defeated at Borosk.

After Vorath
Abandoned by Vorath, a wounded Stalker managed to escape to his birth world of Kamino, where he had the Kaminoan scientists fix him with a cybernetically-grafted. Once he had been repaired, Stalker traveled to Tatooine, where he hid himself among the throes of scum and villainy that generally dwelt on the desert planet. During his time there, he encountered a Force-sensitive man named Leon Valsas and took him on as his apprentice. The two soon became affiliated with a variety of criminal organizations, most primarily the Snatchers.

During the Glorian invasion, Stalker ran into Kyle Katarn once again while on Tatooine. While he and Valsas were able to apprehend Katarn and his party, they were stopped by Jedi V'almarok and. Although Stalker was able to kill V'almarok, Katarn and the others escaped aboard his own ship, the , stranding Stalker and Valsas on Tatooine. Not long after this event, the pair were contacted by the mysterious Revanchist, who offered them both a place in his Dark Jedi Order. While Stalker agreed, if only for a means to get off Tatooine, Valsas refused to have any part and abandoned his master.

Upon joining the Dark Jedi Order, Stalker abandoned his Sith name and became Starkiller once more. When the Dark Jedi allied themselves with the New Jedi Order to take down the Glorian Empire, Starkiller was sent on a mission to Mandalore with Jaden Korr to request the aid of the Mandalorian Protectors. However, their contact — a Mandalorian by the name of Atinar Cabur — turned out to be vengeful towards the Jedi and attempted to kill the both of them. Before he could do so, Starkiller and Jaden were pulled into another dimensional space by the Watcher, the Glorian's de facto ruler. He enlisted the two of them to serve as his agents, accumulating data across the galaxy for the Glorians' use. Left with no other option but a fate worse than death, Starkiller and Jaden accepted the offer.

Behind the scenes
Starkiller/Darth Stalker's backstory continues off of the Dark Side ending for  (but ignores the game's DLC continuation), as the author felt that particular ending should have been the "canon" one rather than the Light Side ending, which posed far more questions and continuity errors (mainly regarding Vader being captured and taken to the Dantooine rebel base).
