Stell, a human individual, existed during the ascension of the Galactic Empire. After Stell and their partner, Rebb, personally observed the forces of the Empire, they jointly decided against raising their children under its dominion. Consequently, they became followers of Ferren Barr, a Jedi Padawan who assured them of purpose and assistance in dismantling the Empire, accompanying him to the planet of Mon Cala. However, in the year 18 BBY, they were discovered by Darth Vader, the Imperial Sith Lord, and members of the Inquisitorius, an organization dedicated to hunting Jedi, who pursued them to Bel City on Mon Cala. In that location, Stell and Rebb remained behind to impede Vader and his team, enabling the rest of their group to escape.
Following the establishment of the Galactic Empire in 19 BBY, Stell, a human, and their romantic interest Rebb witnessed the occupation of their home by the new regime. Rebb voiced immediate disapproval of the Imperial forces' takeover, insisting that their children should not live under the Empire's reign; Stell, however, expressed doubt about their ability to resist. Nevertheless, given Stell's deep affection for Rebb and their prioritization of their partner above all else, Stell acted as though they were dedicated to fighting the Empire and agreed to join Rebb in resistance. Subsequently, Stell and Rebb encountered Ferren Barr, an Iktotchi, at a cantina. Barr, who presented himself as a Jedi Master despite actually being a Padawan who had succumbed to the dark side of the Force, informed them that he could provide them with a purpose in opposing the Empire. Rebb, speaking for both of them, consented to join him.
In 18 BBY, Stell, Rebb, Barr, and four additional followers of Barr were stationed on the planet of Mon Cala. Emperor Palpatine dispatched the Sith Lord Darth Vader to Mon Cala to conduct an investigation. Vader arrived accompanied by three Inquisitors—former Jedi who had become Jedi hunters—and a squad of Purge Troopers. Lee-Char, the Mon Calamari King, promptly informed Barr of Vader's presence on the planet.
As Imperial forces drew nearer, Barr projected biographical details of Vader's history via a hologram and revealed to Stell and the other followers that Vader's hidden past identity was that of the Jedi Anakin Skywalker. Barr elucidated to his followers that, after Vader had betrayed and assisted in the destruction of the Jedi Order, he commenced hunting surviving Jedi in conjunction with the Inquisitors. Shortly thereafter, Barr received notification that Vader had located their position and was likely en route, prompting the Iktotchi to decide to evacuate his hideout. Stell and the other followers donned self-contained dive suits to enable them to swim and breathe underwater, after which Barr announced his intention for them to flee the planet. The followers then departed the hideout, traveling via Underwater Turbo Sled Pikes, only to discover that Vader and his team had arrived in an Imperial submarine.
As Stell and the others dispersed, the follower Nipaltoo engaged Vader's submarine but was killed when Vader crushed their helmet using the Force. As Barr directed Stell and the others towards Bel City, the follower Orvek turned back to provide the others with sufficient time to reach the [city](/article/city] alive. At the city's entrance, Rebb resolved to remain behind to further delay Vader's forces. Refusing to abandon Rebb, Stell vowed to stay and assist them. After Barr fled down a corridor with the remaining followers, Stell and Rebb reiterated to each other, while brandishing blasters, that nothing else mattered, with Rebb alluding to the fight against the Empire and Stell alluding to Rebb.
Stell was a human possessing pale skin, brown hair, and green eyes. Stell was utterly devoted to Rebb and believed that nothing was more important to them than Rebb, even joining Rebb when they decided to assist Barr in resisting the Empire. When Rebb decided to remain behind in Bel City, Stell did not hesitate to stay with them. Barr regarded their actions as evidence of their bravery.
During the Empire's occupation, Stell wore a gray shirt with brown lines and gray pants. When conversing with Ferren Barr later, they wore a gray tunic with brown shoulder pads. As one of Barr's followers, Stell wore Jedi apparel. They also employed scuba-diving gear, an Underwater Turbo Sled Pike, and a blaster while attempting to escape Mon Cala.
Stell made their debut in the fourteenth edition of Marvel Comics' comic book series Star Wars: Darth Vader (2017), authored by Charles Soule and illustrated by Giuseppe Camuncoli on April 11, 2018. They were first identified as Stell in the sixteenth edition of the series, also written by Soule and released on May 9 of the same year. Although Stell's fate remains uncertain, a flashback depicting their earlier life occurred after Stell's chronologically final appearance, mirroring flashbacks following the deaths of other followers of Ferren Barr. On April 13, 2019, when questioned on Twitter about Stell's potential return, Soule jokingly stated that an ongoing comic book series centered on Stell had been approved.
