The RX-78-2 has also been redesigned several times by other artists. In particular, Hajime Katoki's version of the Gundam (referred to as Ver. Ka) has become popular enough to be made into both injection plastic model kits sold by Bandai and resin-based garage kits sold by their B-Club subsidiary. Okawara himself redesigned the Gundam for original character designer Yoshikazu Yasuhiko's manga Mobile Suit Gundam: The Origin, a retelling of the events of the original series. Though mostly identical to the original, it features slightly different designs for its weapons, a small Vulcan pod in its shoulder, and the ability to replace one of the beam sabers stored in its backpack with a cannon similar to that of the RX-77 Guncannon. In addition, the 15th installment of the Gundam Evolve series of shorts features another variation on the RX-78's design, a highly stylized version of the iconic machine based on "modern" design aesthetics. It has been referred as Ver. Evolve 15. The continuing popularity in Japan of this mobile suit has led Bandai to create a 1.5m tall model version, which went on sale in Japan in 2007. The Japan Self-Defense Forces built an approximately full scale RX-78-3 Gundam with styrofoam in its show and contains a simulation pod. Gundam Expo (Hong Kong) uses the RX-78-2's last shooting scene in its logo's X. In the Super Robot Wars series of tactical role-playing games, the Gundam franchise is the chief representative of the "Real Robot" genre and one of the three mainstays of the series (the other two being Mazinger and Getter Robo), and the original Gundam itself is referred to in the series as the in order to distinguish it from its many successors. Role in plot The deployment of the Principality of Zeon's highly agile mobile suits, the MS-05 Zaku I and the MS-06 Zaku II, in the early phase of the One Year War had given the small nation a major tactical edge over the much larger Earth Federation. Due to the widespread use of the Minovsky particles, which interfered with radio transmissions and rendered beyond-visual-range missiles useless, space warfare was reduced to direct fire barrages between large starships and spacefighter dogfights. The Zakus, capable of propellant-less maneuvering thanks to their AMBAC systems and able to be retrofitted to suit a variety of missions and environments, easily outclassed the Federation's arsenal of conventional space fighters and laid waste to
