The Xi Gundam from "Mobile Suit Gundam Hathaway is here", available as a plastic model!! The extremely massive MS, which will be depicted to be over 26 meters in the movie, has been fully recreated in 1/144 scale at a massive 7" for an HG 1/144 model. The movie version's design by Hajime Katoki contains large parts with rear and underside detailing, producing a densely packed design and a massive silhouette.

The points of articulation have been placed in positions after considering the range of movement in various sections of the body, and the transformation into Flight Form can be recreated by rearranging parts. The number of stickers has been reduced and it was designed to be a counterpart to the HG Penelope when they are displayed side-by-side.
