AZI-345211896246498721347/Legends

AZ-345211896246498721347, also known as AZI-3 by clone trooper Fives, was a medical droid in the service of the Grand Army of the Republic during the Clone Wars.

History
AZI-3 was stationed in Tipoca City, on the planet Kamino, helping the medical staff there. When ARC Trooper Fives was brought in following Tup's attack on a Jedi General, he helped in overseeing his treatment and evaluation. AZI-3 told the doctor that the best was to get to the source of Tup's problem would be to do a complete biopsy on his brain, but they did not think it would be helpful.

Later, he was convinced by Fives to do the biopsy and disobey orders given by the doctors. When they found the "tumor" in Tup's brain, they had it removed. This led to the escape by Fives and AZI-3.
