CT-5385 - also known as "Tup" - was a supporting character in Star Wars: The Clone Wars. He was a clone trooper in the Grand Army of the Republic and a member of the 501st Legion under the command of Jedi General Anakin Skywalker. He had begun his service in 20 BBY during the Battle of Umbara, during which time he aided Captain Rex in exposing the fallen Jedi Pong Krell. Like all of Jango Fett's clones, he was voiced by Dee Bradley Baker.

In 19 BBY, Tup took part in the Republic's invasion of Ringo Vinda. During the campaign, he went missing for five planetary rotations before appearing once again and returning to the front line. As the 501st Legion advanced across the Ringo Vinda space station, Tup suddenly began to experience headaches and dizziness. He later fell into a trance-like state, muttering the words "Good soldiers follow orders" as he raised a blaster to Jedi General Tiplar and fatally shot her. Because of this action, the Republic army lost its momentum and was forced to fall back.
Later, Tup underwent a medical examination, but his test results determined that he was perfectly healthy even as his mental stability continued to deteriorate. It was decided that Tup needed to be taken back to Kamino so that the scientists responsible for engineering the clones could determine what was wrong with him. Fives, Tup's fellow clone trooper and best friend, accompanied him to Kamino.
Kaminoan doctor Nala Se determined that Tup was most likely carrying some manner of virus, explaining that she would need to terminate Tup in order to properly ascertain the nature of the infection and develop a defence against it to protect the other clones. In truth, however, Se and the Kaminoan government were secretly in league with the Sith, who had originally commissioned the clone army's creation and had seen that all clones were implanted with neural inhibitor biochips during the breeding process. The Jedi knew nothing about the chips, which were a key element to Darth Sidious' scheme to destroy the Jedi Order. At the appropriate time, a voice command from Sidious would activate the chips, brainwashing the clones into carrying out a secret protocol to exterminate all Jedi. Tup's chip had malfunctioned and activated prematurely, thus resulting in his actions on Ringo Vinda.
Suspecting that something was amiss, Fives worked with medical droid AZI-3 to try and save Tup. The pair were able to distract Nala Se long enough to move Tup into another room and conduct an atomic scan on him. The scan revealed what appeared to be a tumor - actually the neural biochip - on Tup's brain, and so AZI-3 performed a quick surgical procedure to remove it. Shortly after the chip's removal, Tup regained consciousness, stating he was finally "free of the never-ending mission in their nightmares". However, the decay of the biochip prior to its removal had an adverse affect on Tup's brain which led to his death.
