The Celestial Being mothership Ptolemaios can be equipped with special assault containers that contain an arsenal of missiles and powerful beam weapons. The rear section of each container can detach to become an enhancement and support machine known as the GN Arms. Although the GN Arms can fight independently, it has no GN Drive of its own, and so for sustained combat it must combine with a Gundam to form a GN Armor. Of the two machines that have been completed, one is outfitted with Type E equipment for use with the Gundam Exia, and its armament includes a pair of huge GN Swords.
