P-1DK

P-1DK was a Maintenance Droid in the HK Factory in Star Wars: Knights of the Old Republic II: The Sith Lords.

Behind the Scenes
Since the HK Factory was cut from the final game, P-1DK never appeared. However, it was restored by content restoration mods like TSLRCM 1.7. In the restoration mods, it helps HK-47 by disabling his self-preservation protocols, allowing him to fight the HK-50s.
