TK-421/Legends

"TK-421, why aren't you at your post? TK-421, do you copy?"

- Imperial officer Pol Treidum

TK-421 was the designation of a clone stormtrooper stationed aboard the first Death Star.

Biography
At some point during the early stages of the Galactic Civil War, TK-421 went off-duty and went to the Star Tours interstellar travel agency for unknown reasons. His bag was eventually discovered by G2-9T during baggage checks, and upon learning of who it belonged to, decided that TK-421 might have good reason not to be at his regular post before clearing it.

After the Millennium Falcon was captured, he was ordered to stand guard in front of the freighter's boarding ramp, while a scanning crew attempted to determine if anyone was hiding aboard the Falcon.

Just seconds after the scanning crew had made their way up the boarding ramp, a loud thump was heard and someone (Later revealed to be Han Solo) called down to them, asking TK-421 and his fellow guard, TK-422, for help with a piece of equipment. The two stormtroopers made their way up the ramp to assist the technicians; TK-421 and TK-422, were ambushed by Han Solo and stripped of their armor to conceal Han and Luke's identities aboard the Death Star. Treidum later attempted to contact TK-421 questioning him of why he wasn't stationed at his post. Luke Skywalker, having disguised himself as TK-421 at the time, covered up TK-421's current status by motioning his ear to imply that his comlink was broken.

After the battle of Detention Block AA-23, a security team was dispatched to the hangar housing the Millennium Falcon where TK-421 and his comrades were found aboard the Freighter.

Behind the scenes
In the novelization of the movie, the trooper was referred to as THX-1138, a homage to George Lucas's first feature film. In the radio drama, he was referred to as TX-421. In Star Wars 3: Death Star! the character is referred to as TX-421 and as part of Scanning crew BT-445. In the German synchronization of Episode IV, the trooper's designation is TK-241 instead of TK-421. In the video game Star Wars:Jedi Knight II: Jedi Outcast, the character TK-664 is a direct reference to this character.
