LS-757, or L-S-Seven-Five-Seven, was a male Imperial stormtrooper who was stationed in Sector 5-1-5 on the planet Lothal during the Rebel Alliance's attack on Lothal in Star Wars Rebels. In Ahsoka, Ahsoka Tano, Ezra Bridger and Sabine Wren tried to escape from Peridea on the Chimaera before it jumped into hyperspace. LS-757 stood in the hangar bay alongside another Night Trooper. As the ship departed, Bridger and Wren both used a force trick which allowed Bridger to get onto the ship. As Bridger killed the other Night Trooper, LS-757 tried to fire at Bridger, but was gunned down by Wren.
