As part of its military reconstruction following the One Year War, the Earth Federation Forces initiates its Gundam Development Project, the goal being to develop advanced new Gundam-model mobile suit prototypes to test new technology concepts. The intended fourth unit in this "GP" series, the RX-78GP04G Gundam "Gerbera", never sees completion, as the GP04G's concept is basically a space-use repeat of the RX-78GP01 Gundam "Zephyranthes". Civilian contractor Anaheim Electronics is left hanging with a set of plans and an incomplete mobile suit prototype. However, many of Anaheim's engineers are former mobile suit designers from the Principality of Zeon, and they modify the plans and construction of the GP04G into a new, Zeon-style mobile suit. Called the AGX-04 Gerbera Tetra, it carries a powerful beam machine gun and can be equipped with a "sturm booster," which is essentially a large external propellant tank with extra thrusters, making the Gerbera Tetra one of the fastest and most maneuverable mobile suits of its time. When the Delaz Fleet launches its Operation Stardust uprising against the Federation in late UC 0083, Anaheim Electronics - always looking to make a buck by playing both sides against the middle - offers support for Delaz when Vice President O'Sullivan gives the completed Gerbera Tetra to Cima Garahau as a political gesture. In the last stages of Operation Stardust, Cima uses the Gerbera Tetra in a last-ditch fight for her own survival (and ultimately fails).
