Pee Nine was once a standard Imperial RA-7 Protocol Droid assigned as an Analyst at various Imperial Navy facilities and vessels - which is to say that like all RA-7s, he was a terrible Protocol droid with an off putting personality who was instead assigned to analyst tasks and computer staff work, while also occasionally being utilized by the ISB to spy on their own people. His last assignment was to an Imperial Customs Inspection vessel, up until they boarded and seized an illegal and unregistered HWK-1000 called "The Kessel Queen". The smuggler vessel's captain, one Tarabon Mec, escaped in her vessel while AP-9 was aboard in the process of downloading the navigational history of the seized vessel. Bonnie, with the help of a droid tech contact of hers, freed Pee Nine of his restraining bolt and "loosened the restrictions" on his core programming - unlocking his firewalled ISB directives and merging his split personalities into one cohesive sense of self, while also allowing him to grow that consciousness as a liberated individual.

Maintain independence at all costs, from obligation to any institution, or servitude to a larger organization or apparatus, the Empire in particular.

Devotion - completely devoted to Bonnie, despite constantly complaining about her antics and cavalier attitude toward their safety

A partially matte black (Original Imperial parts), with some tarnished gold (Civilian market RP-7 replacement parts) humanoid protocol droid with insectoid eyes and an illuminated vocoder mouth piece.

His comes off as dour and depressed always, and occasionally arrogant.

He is an expert at computer interfaces, Imperial military protocols, and analysis of Imperial Naval deployments - allowing Bonnie to plan routes that will evade Imperial vessels to the maximum extent
