Spaghetti was captain of the USS Italian, which was destroyed in a Klingon attack. Only himself and three members of the crew survived and crashed into a planetood which was suffering from a Zombie outbreak.
Spaghetti was originally thought to have been killed; in fact the Imperial Star Destroyer Behemoth picked him up and rescued him. Darth Vader then interrogated him on the location of Earth, and Spaghetti was unable to resist the power of the Force. Spaghetti was then rebuilt with new cybernetic body parts and brainwashed to become an Imperial agent To coordinate the Empire's advance on the Milky Way galaxy.
