Notes & Trivia

• This Gunpla is the first HGUC iteration of the Crossbone Gundam unit, and the second HG iteration since HGBF Crossbone Gundam Maoh.
• The Gunpla's design is based on it's Katoki redesign rather than it’s original manga design, this is noticeable in the added mechanical details such as the squares on the bottoms of the shoulders and the ”screws” on the thighs. Interestingly the revive series that would soon follow this kit would focus heavily on the original source designs. The result of this is that the RG, HG and MG Crossbones are very similar in appearance and that no official manga accurate model kit exists officially at this time.
