The Gaddess is one of the "GNZ series" mobile suits developed and used exclusively by the Innovades that called themselves Innovators. This GN Drive Tau-equipped machine is a variant of the GNZ-003 Gadessa, and was made specifically for Anew Returner, a spy who had infiltrated Celestial Being. Unlike the other Innovators who are combat-type, Anew is an intelligence gathering-type, so her mobile suit was equipped with multiple wireless, remote-controlled weaponry, the GN Beam Saber Fangs, to avoid direct combat as much as possible. The basic tactics of the Gaddess focused on avoidance of direct combat, with the GN Beam Saber Fangs also used to keep enemies away, creating a gap for the mobile suit to escape.

Despite this, the Gaddess is capable of close combat with its handheld GN Heat Saber, and has the same forearm-mounted GN Vulcans and GN Cutters as the Gadessa. Like the other GNZ series machine, the Gaddess can receive support from the quantum processing system, Veda, granting it performance superior to ordinary mobile suits'.
