The AGX-04 Gerbera Tetra is a prototype assault mobile suit designed by Mika Akitaka and was featured in the OVA Mobile Suit Gundam 0083: Stardust Memory. It was piloted by Cima Garahau.
As part of its military reconstruction following the One Year War, the Earth Federation Forces began its Gundam Development Project in collaboration with Anaheim Electronics, the goal was to produce new experimental Gundam-type mobile suits. The intended fourth unit in this GP series was the RX-78GP04G Gundam "Gerbera". Its design sought to replicate the high-speed mobile suit assault tactic successfully established by the Principality of Zeon late in the war, in which a single mobile suit was able to penetrate the enemy forces and deal heavy damage as exemplified by the MS-18E Kämpfer.
In U.C. 0083, the Delaz Fleet launched Operation Stardust, an uprising against the Federation. Anaheim Electronics, while supporting the Federation, also offered to support Aiguille Delaz. Vice-President O'Sullivan then gave the completed Gerbera Tetra to Lieutenant Colonel Cima Garahau as a political gesture.
