spider-like droids that were developed during the reign of the Galactic Empire under the direction of Darth Vader on the planet Kamino. Following the escape of a clone of Galen Marek, Vader dispatched the bounty hunter Boba Fett to track down the clone's progenitor's love Juno Eclipse. Taking a number of Imperial resources, Fett struck the Rebel starship Salvation and deployed a large contingent of Terror Droids to deal with the Rebel troopers onboard. The droids later encountered Starkiller who had arrived to save Eclipse from the Imperial attack. It was later revealed that these spider droids came from the Terror Walker, their larger counterpart.
