TK-421

TK-421 was the designation of a human male Imperial stormtrooper who served on Lasan before he was stationed on the Death Star battle station. In 1 BBY, he worked in the Sector AA-345 Maintenance Unit alongside the MSE-6 series repair droid MSE-6-G735Y, but he hoped to secure a transfer to Coruscant to enter the droid on the racing circuit.

TK-421 caught the attention of Grand Moff Wilhuff Tarkin through an accidental holorecording of himself without his helmet that was displayed due to MSE-6-G735Y crashing into Tarkin and malfunctioning. When Tarkin sent a message back for TK-421 to report to his officer's quarters to repair his aqualeisure unit, TK-421 understood Tarkin's implied intentions and saw an opportunity for himself and his droid to advance. Tarkin and TK-421 began a clandestine intimate relationship that progressed quickly. TK-421 was promoted to station security, a position that Tarkin believed would be safe, and the stormtrooper hoped he and his droid would soon be relocated to Tarkin's penthouse on Coruscant.

Alongside TK-710, TK-421's first security assignment was to guard the Millennium Falcon in Docking Bay 327 after the Death Star captured it. The stormtroopers were tricked by Captain Han Solo into boarding the light freighter and were killed. TK-421's stormtrooper armor became a disguise used by Luke Skywalker to rescue Princess Leia Organa. Tarkin vowed to MSE-6-G735Y that he would avenge the droid's master by eliminating the Rebel Alliance, but shortly afterward, the Death Star was destroyed.
