NON units, otherwise referred to as NONs, represented a specific build of protocol droids utilized by senators and various functionaries within the Galactic Republic. A NON unit, specifically NON-3, was allocated to Padmé Amidala; however, it underwent a reprogramming process to lure her into a deadly death scenario, from which Bail Organa rescued her. Additional senators who were assigned NON units encompassed figures such as Rush Clovis and Organa himself.
