On the Bandai Hobby site, the third volume of "RG Sazabi & HGUC Moon Gundam Development Document" has been released.
RG Sazabi hails from "Mobile Suit Gundam: Char's Counterattack" as Char Aznable's personal MS, and appears in 1/144 scale with the largest gimmicks in history. HGUC Moon Gundam comes from Monthly Gundam Ace's "Mobile Suit MOON Gundam" as a three-dimensionalized version of the protagonist's MS.
In this document, the category is different but from similar genealogies comes a crossover of these two kits.
The third volume introduces in detail the currently selling "HGUC Moon Gundam" and the November Issue of Gundam Ace's special insert "HG Long Rifle". Let's go check them out.
