Commander Merrejk, a Human serving the Imperial Navy, held a commander rank during the Galactic Civil War's most intense period. This skilled Imperial operative, adept at both espionage and reconnaissance, frequently adopted the guise of a freighter captain conducting supply missions to the Outer Rim Territories, all the while secretly observing Rebel and underworld activities. By the year 4 ABY, Merrejk found himself stationed on Darth Vader's command vessel, the Super Star Destroyer named Executor. There, he served on the bridge directly under the authority of Admiral Firmus Piett. In the initial phases of the Battle of Endor, Merrejk informed Piett that the Executor had achieved its designated attack position. Piett, however, instructed that the starship maintain its current location, intending to allow the second Death Star's secretly operational superlaser on the battle station to unleash its destructive power upon the Alliance Fleet. Ultimately, the battle resulted in the destruction of both the Executor and the Death Star.
During the Galactic Civil War, Merrejk, a Human, held the rank of commander within the Imperial Navy. As a highly skilled spy and scout for the Galactic Empire, he frequently disguised himself as a freighter captain, conducting supply runs to the Outer Rim Territories. His main task was to keep a close watch for unlawful Rebel activities and other criminal behaviors. By 4 ABY, Merrejk was assigned to Darth Vader's, the notorious Dark Lord, flagship, the Super Star Destroyer known as the Executor. His duties involved guarding the second Death Star battle station, which was under construction in orbit above the remote Forest Moon of Endor.
In the opening moments of the crucial Battle of Endor, Merrejk was positioned on the bridge of the Executor, serving under the command of Admiral Firmus Piett. He informed his superior officer that the warship, leading the massive Imperial Fleet awaiting the Alliance Fleet's arrival, had reached its designated attack position. However, Piett instructed Merrejk to maintain their current location, revealing to Commander Gherant, another officer aboard the Super Star Destroyer who was standing nearby and visibly surprised, that the Executor's sole purpose was to prevent the Rebel Fleet from escaping. Emperor Palpatine had a special surprise prepared to destroy them: the fully operational superlaser of the still-incomplete Death Star. The battle concluded with the Executor colliding with the Death Star, resulting in the destruction of both.
During the Battle of Endor, Commander Merrejk was seen wearing the black version of the standard Imperial officer's uniform, without rank insignia, and a chrome utility belt.
Merrejk's initial appearance was in the 1983 film Star Wars: Episode VI Return of the Jedi, where he was portrayed as an uncredited extra. His single line, in which he alerts Admiral Firmus Piett that the Executor was ready, is unique to the film and does not appear in the Return of the Jedi novelization, where Piett independently decides that the ship will hold its position. The character of Merrejk was first identified by name and given a brief backstory on the "Commander Merrejk" card as part of the July 2000 Death Star II Limited expansion set for the Star Wars Customizable Card Game.
While there is no official Star Wars source that discusses Merrejk's fate during the Battle of Endor, which resulted in the Executor's destruction, Leland Chee, the keeper of Lucasfilm's Holocron continuity database, was asked on his personal Facebook fan page whether Merrejk died during the Executor's destruction. He responded that he was "Not sure why we'd go out of the way to say he's alive," and that it is "Best to presume dead unless proven otherwise."
