TK-450 was a male human stormtrooper who served the Galactic Empire. TK-421 sent MSE-6-G735Y to deliver a scanner servo to TK-450 at Docking Bay 228 on the Death Star. TK-450 then received G7 at the docking bay and asked what taken the "guys" down there so long, since he had to endure demanding Imperial officers like General Cassio Tagge and Grand Moff Wilhuff Tarkin, and Darth Vader.
