Technical and Historical Notes

The RX-178B Gundam Mk-II was a custom Gunpla created by Sei Iori. It was based on the RX-178 Gundam Mk-II from the 1985-86 anime TV series Mobile Suit Zeta Gundam. The Mk-II’s design was inspired by both Sei’s own GAT-X105B/FP Build Strike Gundam Full Package and the Zeta Gundam upgrade unit FXA-05D G-Defenser. Like the G-Defenser, the Build Booster Mk-II docked with the Gunpla to increase its firepower and mobility. The Build Gundam Mk-II’s basic armaments were the same as its anime inspiration, and the Build Booster Mk-II added a pair of beam rifle Mk-IIs. Sei debuted the Build Gundam Mk-II after the Build Strike Full Package was heavily damaged in a Gunpla Battle against Tatsuya Yuuki’s MS-06R-AB Zaku Amazing. After Sei and Reiji won the 7th Gunpla Battle World Championship, the large Arista crystal underneath the PPSE stadium went out of control, causing damage in the real world. Sei used the Build Gundam Mk-II as part of a team effort to neutralize the crystal.
