Winshur Bratt originated from the town of Bela Vistal on the planet of Corellia; he was a male human from Corellian descent. He entered the world one year after the Battle of Yavin and was subsequently placed in a religious center. Remaining there until adulthood, he eventually secured a position in Coronet City as the leading clerk within the Records Department of the Corellian Engineering Corporation. Following the First Order's takeover, Bratt was elevated to the role of Executive Records Officer, supported by his assistants Yama Dex and Monti Calay.
During 34 ABY, while holding this position, Bratt had an unpleasant reunion with Navah, a former classmate from the religious center. He also reprimanded Dex for violating company policies. One day, accompanied by Colonel Genial, a First Order reform officer, Bratt was assigned the task of allocating labor to prisoners who had been transported to Corellia, utilizing lists of their names. He was also responsible for maintaining the security of these lists, restricting access to himself and First Order High Command. After sharing a luncheon with Genial and the businessman Hasadar Shu, Bratt, fueled by frustration from the luncheon and Dex's minor offenses, physically assaulted Dex until she bled.
Following Genial's accusation that Bratt was collaborating with Calay, who had been exposed as a First Order traitor for stealing the lists, Bratt joined the reform officer at a party hosted by Shu. His aim was to recover the lists and clear his name. When they were alone, Bratt killed Genial by pushing him from a bridge into the sea below, intending to independently locate and deliver Calay to the First Order, thereby dispelling any suspicion directed at himself. He later engaged in a confrontation with Dex, who threatened him with a pipe. Ultimately, Bratt faced Teza Nasz, a former Imperial warlord recruited by the Resistance, who confronted and killed him.
In 1 ABY, Winshur Bratt's birth occurred in Bela Vistal, a town situated on the Corellian planet of Corellia, within the Core Worlds. Born into a middle-class family, Bratt was placed in a religious center by his mother, an institution that, along with his mother, he developed a strong aversion to over the years. During his time at the center, he was nicknamed "Bratty" by the children there. Growing up, Bratt witnessed the presence of Imperial stormtroopers who had occupied the town during the ongoing Galactic Civil War. Upon reaching adulthood, he ventured to Coronet City in search of employment.

Within a half-year of his arrival, Bratt was appointed as the head clerk for the Records Department of the Corellian Engineering Corporation. He maintained this position after successfully completing a re-employment interview conducted by a First Order officer when the First Order established military control over the corporation. Eventually, he was promoted to Executive Records Officer and was given his own office in Building Two, supported by Yama Dex and Monti Calay as his assistants. At one point, Bratt encountered Hasadar Shu, a businessman, at an informational session concerning a new park being constructed in Coronet City's government district.
In 34 ABY, Bratt received a message from his mother, but he deleted it due to his deep-seated hatred for her. One day, while waiting for clearance to enter his office in Building Two, after presenting his work identification card to the building's guard for inspection, he was approached by Navah, a former classmate from the Bela Vistal religious center. As they conversed, Bratt grew agitated by Navah's presence, as he had distanced himself from his hometown and anyone connected to it. After receiving clearance to enter, he left without saying goodbye, considering her insignificant. On his way to his office, Bratt nodded to Colonel Genial, a reform officer from the First Order's Reform Office.
Upon entering his office, Bratt began managing the company's records. He summoned Dex after noticing two new boxes of records on his desk but noticed that her hair did not meet the company's regulation upon seeing her. The girl claimed that she was running late for work that morning and did not have time to change it, but Bratt snubbed her before she could continue. He began explaining how creatures were ruled by the strongest among them and that humans were measured by their level of discipline. He then asked her whether she wanted to be powerful or be crushed by her weakness before instructing her to straighten her belt and adjust her hair. After dismissing her and handing her the boxes to be organized, he further stated that the violation would be added to her permanent record and would result in disciplinary action.
At a later point, Bratt was visited by Calay, who presented him with an urgent and confidential communication on a datapad from Bratt's superior. Dismissing Calay, he watched the message, recognizing the First Order officer in the hologram as the one who had conducted his re-employment interview. Bratt was given three documents containing multiple lists of prisoners to be transferred to Corellia and was tasked by the officer with assigning labor work to the prisoners as well as securing the documents so that they could only be accessed by himself or personnel from First Order High Command. The officer informed Bratt that he would be working with Colonel Genial to oversee the placement of the prisoners in the Corellian shipyards' labor pool. Before terminating the hologram, the First Order officer also stated that Bratt would be transferred to High Command if the tasks were successfully completed.
Bratt inspected the list of names, recognizing a number of them. He learned that the prisoners were former politicians and realized that the assignment was an opportunity to prove himself and become someone of importance. After deciding to acquire the job roster from the Employment Department in order to gain a better understanding of the prisoners' assignments, he summoned Calay and tasked him with managing the office while Bratt retrieved a number of records from the department.
During the assignment, Bratt observed the prisoners' arrival, accompanied by Calay. His assistant questioned if the prisoners would be executed, to which Bratt replied that the First Order was merciful and allowed them to live by doing hard labor. Bratt then opened his datapad and matched the names with the prisoners' faces. He assigned different tasks to various prisoners before stopping at Ransolm Casterfo, recognizing his notoriety in politics. Bratt was then approached by Genial, who ordered him to continue assigning labor work to the other prisoners. After finishing his work, Bratt returned to his office.
In his office, Bratt—exhausted from the assignment—was approached by Dex, who expressed her worries about his condition. The officer told her to instead focus on completing the tasks she was previously assigned. He was then informed of his appointment with Hasadar Shu, arranged by the girl herself, as the businessman had revealed that he knew Bratt personally while speaking to her. Bratt attempted to cancel the meeting but learned that Shu had already arrived outside his office and was chatting with Genial. He then hastily prepared his uniform and left to meet the two. As the three conversed, Bratt felt uneasy, as Shu had claimed that he was an old friend of Bratt's, though Bratt disputed the claim by stating that they were only acquainted. Bratt then took notice of Dex, who smirked as she turned away. Bratt speculated that Dex had either laughed at his misfortune or had deliberately set up the meeting, before the three men made their way to lunch.
Bratt considered the luncheon to be a failure, as he struggled to have a meaningful discussion with Shu to figure out how the businessman knew him personally. At one point, Bratt choked on his food, prompting Shu to offer him a glass of water. Upon returning to his office after the lunch, he found Dex and Calay together and questioned why supplies were scattered around the room, unaware that Dex had dropped them while confronting Calay about his theft of the datapad containing the lists of prisoners from Bratt's office. Bratt then instructed the girl to clean up the room and gather the reports he had requested before the lunch. After Calay claimed to be ill at that moment, Bratt dismissed him in order to avoid falling ill himself. He then told Dex to cover for Calay in case Bratt needed assistance.
Later during that day, Bratt attempted to call Dex in order to have her make caf for him, but she did not respond. The lack of a response prompted Bratt to leave his office and notice the girl asleep at her desk. Due to the frustrations he had built up from his lunch with Shu and Genial as well as the girl's mannerisms and actions over the preceding weeks, Bratt proceeded to knock Dex off her chair and beat her until she bled. Afterward, he staggered on the way to the restroom, where he vomited all the food he had eaten into the sink. Although he questioned his own behavior just then, Bratt concluded that the girl deserved what had happened to her.
After washing his face, Bratt was approached by Genial, who revealed that Dex had informed him about Calay's theft of the datapad. Since Calay, who was thus considered a traitor, operated under Bratt's supervision, Genial accused Bratt of working with him. Bratt ultimately shouldered the blame for his assistant's actions, making him answerable to High Command, as the lists were meant to be kept secure by the Executive Records Officer. Bratt was also accused by the colonel of working with environmental activists alongside Shu during their informational session.
Genial further speculated that Bratt intended to give the stolen lists to Shu at the luncheon but was prevented from doing so by the reform officer's presence at the pair's meeting. According to Genial, Bratt had Calay take the lists from his office instead. Exhausted and facing a dire predicament, Bratt left the office with a disheveled appearance and accompanied Genial to a party held by Shu in order to seize the lists from Calay and clear his own name. However, while leaving, Bratt failed to notice a hidden group of Resistance members that was observing him.
As Bratt and Genial made their way through the streets of Coronet City to attend Shu's party, the colonel repeatedly insulted Bratt for his incompetence. Bratt slowly began to evaluate his own loyalty to the First Order as well as his identity but, after hearing Genial's fifteenth insult toward himself, concluded that he was completely loyal to the regime and was not a traitor. Bratt also became determined to hand over Calay to the First Order by himself and thus be cleared of any suspicion. When the pair reached a bridge, Bratt noticed the sea that the city bordered. With no witnesses present, Bratt ran toward the colonel and knocked him over the bridge's railing. Genial was sent falling into the sea below to his death, and Bratt subsequently ran back to his office.

Upon returning to Building Two, he noticed Dex sneaking around inside. He watched as the girl entered an underground passage that led to the shipyards and pursued her. Bratt eventually lost sight of her in the dark tunnel and started running, before Dex reappeared in front of him with a pipe in her hands. Bratt slowly approached her while reminding her that power came from discipline. When they were close, a scuffle ensued between the two. Bratt managed to wrest the pipe from her hands, causing Dex to fall to her knees. Preparing to swing the pipe at her, he was interrupted by Teza Nasz, an ex-Imperial warlord who was allied with the Resistance. Nasz threatened to shoot Bratt if he did not surrender the pipe to Dex.
Bratt refused and was promptly shot in the stomach by Nasz. He collapsed on the floor and watched as other Resistance members made their way to Nasz and Dex. He was then approached and nudged by Casterfo, who had been rescued by the Resistance. Casterfo offered the dying officer assistance, but Bratt refused, as he was certain of his fate, prompting Casterfo to leave with the others. In his final moments, Bratt thought about how violence had led him down a path with false promises of power and realized that instead of saving him, it had doomed him.
Winshur Bratt, a male Corellian human, was profoundly affected by his time in Bela Vistal's religious center. This experience led him to despise his mother and anyone associated with his hometown over the years spent there. He went so far as to delete an unopened communication from his mother in the hopes that she would realize he had distanced himself from his past completely.
While conversing with Navah, Bratt wished to part ways with the woman as quickly as possible when he learned she was a classmate of his at the religious center. When they subsequently separated, Bratt did not bid her farewell, viewing her as an insignificant person due to her job in the working class and her dirty appearance. He also considered reporting her for assault when she squeezed his arm.
When he was promoted to Executive Records Officer, Bratt took great pride in his new job and was joyful when his interviewer told him he was the kind of citizen the First Order was searching for. Bratt had a commanding presence in front of his assistants. He viewed Yama Dex as a nuisance due to her messy appearance and demeanor but considered Monti Calay an obedient aide. However, he faltered when in the presence of Colonel Genial and Hasadar Shu, the latter of whom had merely met Bratt but claimed to be an old friend of his. During their luncheon, Bratt considered Genial to have a joke of a name after learning it. He later took out his personal frustrations on Dex and beat the young girl until she bled, blaming her for his own misfortunes.
Even after facing accusations of treachery, Bratt firmly believed in everything the First Order represented and wanted to prove himself to the regime. After examining his own loyalty, he concluded that he had devoted everything to the First Order's cause and upheld its values. Bratt held to his ideals until the moment he was shot and left for dead, which filled him with regret. While slowly dying, Bratt finally realized that violence had betrayed and doomed him with false promises of power and that his assistants were not to blame.
Winshur Bratt was created for Resistance Reborn, a 2019 novel written by Rebecca Roanhorse. Intending for Bratt to be the "villain" of the story, Roanhorse wrote his character arc to show what it was like for such a character to accept inevitable circumstances, playing along with the First Order's rules to profit from their power and going so far as to bully a young girl like Dex in order to achieve a higher status with the regime. According to Roanhorse, these actions slowly stripped away Bratt's identity as a person.
