LS-515, a scout trooper serving the Galactic Empire, was a human of the female persuasion. While she and her speeder-riding companion, LS-412, were on patrol near an Imperial dig site focused on the Lothal Jedi Temple, the Spectres rebel group ambushed them. The rebels then pilfered the scout troopers' armor to use as disguises for their own purposes.
Stationed on Lothal during 1 BBY, LS-515 served as a female scout trooper. She and LS-412, her wingmate, were tasked with patrolling the outer limits of the excavation camp located outside the Lothal Jedi Temple, utilizing 614-AvA speeder bikes. During one such patrol, they happened upon a holographic projection featuring Grand Admiral Thrawn discussing the Battle of Atollon. Subsequently, the Lasat Garazeb Orrelios, a member of the Spectres rebel group, knocked both LS-515 and LS-412 unconscious. Her helmet was dislodged by Zeb's strike.
Following this, the rebels Sabine Wren and [Ezra Bridger](/article/ezra_bridger] absconded with her and LS-412's armor, using it to infiltrate the Imperial camp. Despite the rebels' attempts at deception, the absence of LS-515 and LS-412 was noticed by their fellow Imperials. While Sabine and Ezra were attempting to unlock the secrets of the Painting of the Mortis gods, a stormtrooper questioned "LS-515" about her and LS-412's deviation from their assigned patrol route. Sabine dismissed this as a simple misunderstanding and offered to resolve the issue at "Operations." However, at the mobile command center, the Imperial Minister Veris Hydan unmasked her as a rebel spy, instigating a camp-wide lockdown.
LS-515 made her debut in the Star Wars Rebels episode "Wolves and a Door," which aired on February 26, 2018 as part of Season Four. Vanessa Marshall, who also provided the voice for the rebel protagonist Hera Syndulla, voiced her character.
