the AGX-04 Gerbera-Tetra Cima Garahau Custom MS

The intended fourth unit in this "GP" series, the RX-78GP04G Gundam GP04G Gerbera, never saw completion. Civilian contractor Anaheim Electronics was left hanging with a set of plans and an incomplete mobile suit prototype. However, many of Anaheim's engineers were former mobile suit designers from the Principality of Zeon, and they modified the plans and construction of the GP04G into a new, Zeon-style mobile suit.
Called the AGX-04 Gerbera-Tetra, it carried a powerful beam machine gun and could be equipped with a "sturm booster," which was 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 launched its Operation Stardust uprising against the EFF in late UC 0083, Anaheim Electronics - always looking to make a buck by playing both sides against the middle - offered support for Delaz when Vice President O'Sullivan gave the completed Gerbera-Tetra to Cima Garahau as a political gesture. The rollout version retained the Gundam-style faceplate and binocular eyes, but these were replaced with a standard Zeon monoeye once the suit was handed over to Cima. In the last stages of Operation Stardust, Cima used the Gerbera-Tetra in a last-ditch fight for her own survival (and ultimately failed).
