The G Structure diorama series, built to display 1/144 scale HG Gunpla, is bringing back Heliopolis from Mobile Suit Gundam SEED as an affordable unpainted semi-finished kit. Reservations open September 10, 2026 at 10:00 AM at hobby shops and online stores nationwide. The Heliopolis Battle Stage (Material Color Edition) reproduces the space colony's streets, with some buildings and support arms using 3mm joint pins for flexible layouts. Priced at 8,580 yen including tax, it ships in February 2027 from MegaHouse. The set does not include HG Gunpla figures.
The kit reproduces the streets of the space colony Heliopolis, where Mobile Suit Gundam SEED begins. Some buildings and the included support arms use 3mm standard joint pins, so the layout can be rearranged to fit the display space. The main body is partially assembled in molded colors, and the set includes water-transfer marking decals for adding detail. The main body stands about 175mm tall, with the included anchor reaching about 230mm. Builders can recreate the confrontation with the GINN from episode 2, which opened the main story. The product does not include the HG Gunpla figures.
