Exo

Exo was a protocol droid who assisted a spy in the Rebel Alliance. The spy obtained schematics for a key factory of the Galactic Empire, who tracked down and destroyed their base. Exo and the spy were the only survivors of the attack, escaping into hyperspace, but were pursued by Imperial Commander Tylux, who refused to fail the Empire. Using Tylux's determination to capture the spy at any cost, the two rebels led the commander into a trap that left his Star Destroyer disabled, allowing a rebel fleet to emerge and destroy it.
