The 1st and 3rd Gundam were designed by Okawara between 1980 and 1983 for Gundam Century and the Mobile Suit Variations series of models. This particular variation, the third of the group, also appeared in the novel version of Mobile Suit Gundam as G-3 Gundam; it featured unique magnetic coating on the joints to increase the pilot’s response time.

An updated version of this kit and the other RX-78 variants have been released; you can find them in the related items section of this page!
