Au B'ree, a Devaronian employee stationed at the Fekunda Outpost, found herself under the authority of Commander Zhou and his stormtrooper squad when they seized control. Upon the Galactic Empire's arrival at the outpost, demanding shipments of phareen to bolster their supply networks, she initially felt reluctant towards participating in acts of rebellion directed at the Empire. While Burl was enthusiastic about the prospect of resisting, Au B'ree cautioned her colleague, emphasizing the potential for Imperial reprisal against the entire population—she hoped that compliance would lead to the Imperial troops' departure.
However, in response to Burl's appeal, Hera Syndulla arrived and inspired Au B'ree to recognize and utilize her inherent leadership skills, commending the Devaronian's calm demeanor and talent for establishing achievable objectives. Syndulla surprised her by proposing that Au B'ree would be the ideal figure to lead any resistance movement that might arise on Fekunda. She contributed to Syndulla's strategy to liberate the outpost from Imperial occupation by disrupting the stormtroopers' operations in phareen processing. Following their triumph, she anticipated future collaboration with the Rebellion.
Au B'ree's debut occurred in the third issue of the Star Wars: Forces of Destiny comic series, penned by Devin Grayson and brought to life through the illustrations of Eva Widermann.
