This co-pilot was a human male who served in the Galactic Empire, and was aboard the Death Star when it destroyed Alderaan. Around 9 ABY, he served in Gideon's Imperial holdout. He and and the primary pilot aboard the Lambda-class T-4a shuttle designated Shuttle 2743 were attacked by the Firespray-31-class patrol and attack craft Slave I while ferrying Doctor Pershing.
The Slave I immobilized the shuttle and clamped to it, the Mandalorian Din Djarin entering the vessel. The co-pilot held Pershing at gunpoint, and shot the other pilot when he attempted to resolve the confrontation. He then taunted the Alderaan survivor marshal Cara Dune until she shot him to death.
