Biography
AZ-3 served in the medical facility at Kamino's Tipoca City. He was present for the arrival of "Tup," a clone trooper who was suffering from a mysterious condition that had caused him to attack and kill the Jedi General Tiplar. He was assigned to oversee testing on Fives, whom it was believed might have been exposed to whatever condition had affected Tup.

Fives, wanting to help his friend Tup, used a wordplay to convince AZ-3 that, by not helping the patient, he was doing the opposite of what he was programmed to. After convincing AZ-3 to help him, Fives explained to the droid that no clone went by a number these days and his camaraderie with Tup. AZ-3 suggested that a complete Level 5 atomic brain scan on Tup, but the Kaminoan doctor refused, AZ-3 being unaware that she had her own agenda.

Continuing to work with Fives, AZ-3 performed the procedure, eventually conducting a biopsy based on the readings, and discovered a mysterious "tumor" inside Tup. It transpired that the tumor was actually a control chip and when it was removed, Tup died. It was discovered that, in fact, all clones had such a chip, the stated purpose of which was to prevent clones from being overly independent and aggressive, but actually could be used to execute Order 66. AZ-3 was threatened with having his memory wiped for his knowledge of these chips and malfunctioning, but his ultimate fate was uncertain.
