TK-450 was a stormtrooper of the human variety, and of male gender, who was in service to the Galactic Empire. A scanner servo was dispatched to TK-450 by MSE-6-G735Y on the order of TK-421, with the rendezvous point being Docking Bay 228 located on the Death Star. Upon receiving G7 at the docking bay, TK-450 inquired as to the reason for the delay in the arrival of the others, stating that he was forced to deal with high-ranking Imperial officers such as General Cassio Tagge, Grand Moff Wilhuff Tarkin, and Darth Vader.
