Bandai 1/144 HG RX-78GP01 Gundam GP01 Kit

As described in the Master Grade model manual and MS Encyclopedia, at the conclusion of the One Year War, the Federation started the Gundam Development Project, aimed at creating mobile suits superior to those that Zeon had developed. The RX-78GP01 Gundam "Zephyranthes" was the second of five Gundam type mobile suit prototypes completed under this plan.
