HK-50h was a Hunter-Killer droid created on Telos by G0-T0. Until HK-47 found the HK factory, she tirelessly hunted as many Jedi as possible. She failed, of course. She was ordered by G0-T0 to return and be executed for her failure. That was HK-47 showed up and allied with the HK-50s and 51s. He ordered her execution to be canceled. HK-50h, happy to have a 2nd chance, became to Factories' guard. She worked happily until a cave in when Czerka Corp. came in and reactivated the defenses. The following crash severely injured her. HK-50j later found her and repaired her. She then continued to guard the factory.
