A graduate of an Imperial Academy, this captain within the Stormtrooper Corps of the Galactic Empire served under the command of Darth Vader, the Sith Lord, as part of the military forces deployed to the planet Shu-Torun. Their mission was to bolster the loyalist faction during a civil war that took place during the era of the Galactic Civil War. Following the successful suppression of the rebellious ore-dukes by the combined Imperial and loyalist forces, the captain accompanied the Sith to his awaiting Lambda-class T-4a shuttle for departure. However, before leaving, Vader reassigned the officer, tasking them to remain on Shu-Torun as a military advisor to Queen Trios, the loyalist ruler, while the remaining Imperial troops withdrew. After the shuttle's departure, the captain and Trios departed the landing platform together. During this time, the queen inquired whether the captain possessed dancing skills, emphasizing that dancing was a required skill for everyone within Shu-Torun's courtly society to the stormtrooper. The captain's stormtrooper armor featured an orange pauldron, a visual indicator of their rank.
The comic book Darth Vader (2015) 19 from 2016, penned by Kieron Gillen and brought to life through the illustrations of Salvador Larroca, marked the captain's initial appearance. The comic refrained from revealing the captain's name, operating number, or gender. Although a stormtrooper captain made multiple appearances on Shu-Torun throughout the third arc of the Star Wars: Darth Vader series, it remains uncertain whether these instances depict the same individual; therefore, this article refrains from making such an assumption.
