Cybernetic psychosis represented a state where cyborgs with brain-modifying cybernetic implants, or those who were borg constructs, could experience mental breakdown. This occurred when the cyborg's mental faculties were no longer capable of governing the cybernetic computer, ultimately leading to a state of madness.
One instance involved a cyborg pilot afflicted by cybernetic psychosis, resulting in a descent into madness and the delusion that a Z-95 Headhunter, flown by Jaina Solo, was actually the prototype Onyx Star. This pilot was under the false impression that the Tenloss Syndicate had hired him to stop its shipment to the SoroSuub Corporation.
