Toyoppe brings out his own version of an SD GX-9900-GB G-bit D.O.M.E based on the mecha from After War Gundam X anime series. The complete title for this Gundam papercraft would be GX-9900-GB G-Bit D.O.M.E
It's a mobile suit from the United Nations Earth that was based on the FX-9900 GX-Bit. The G-Bit D.O.M.E is very similar to the GX-Bit except for an additional buster rifle and chest vulcan gun. This Gundam was used to protect and guard a moon base.
This G-Bit D.O.M.E papercraft includes the satellite cannon (mounted on its backpack).
