KT-10 was an astromech droid with a programmed female personality. She was captured by the giant droid known as the Great Heep on Biitu, and she and fellow astromech R2-D2 became romantically interested in each other while the two were being held captive in the Heep's droid harem. KT-10 was eventually fed to the Heep, had her power drained, and was deactivated. R2-D2 and the Heep's other astromech droid prisoners rescued her from the junkyard where she had been deposited and gave their power up to reactivate her.
