D66
D66 was a Dum that worked with Jaybel Tyrus in Settlement 26 on the planes outside Kaldor City. It was a second hand model and spent more time being repaired than dong it's job.
Tyrus instructed D66 to stand in the middle of the road to stop the prospector's caravan when it approached. When the Voc V11 tried to persuade the Dum to move Tyrus hit both robots with an EMP gun and deactivated both of them.
Later, in the repair shop, D66 suddenly reactivated and tried to communicate with the repairer Kaden Olson what was wrong with it. Later Tyrus shot D66 and the other robots, with the same EMP gun, so badly there was no hope of repair. (AUDIO: Toos and Poul)
