Zero-1
this was the designation of the Q9-series astromech droid used by Kyp Durron, during the struggle against the Yuuzhan Vong. Zero-1 had once been owned by a Mon Calamari philosopher, and was purchased at auction when Kyp went on his own, independent crusade against the Yuuzhan Vong. Zero-1 never truly had its memory systems erased, and continued to respond to Kyp's queries with rhetorical questions and probing dialogue. Kyp later explained that the droid's name was a joke on the philosophical belief that all life can be reduced to the binary code of zeroes and ones.
