As indicated by its model number, the Gundam Dantalion is one of the last amongst the 72 Gundam Frame machines to be produced during the Calamity War. During its development, its plan underwent several major revisions based on the combat data of earlier Gundam Frame machines battling against the mobile armors. In the end, the Gundam Dantalion was designed as a machine capable of making significant impact on any battlefield, and could handle any combat situations. This was achieved through equipping the Gundam Dantalion’s basic Naked form with the appropriate equipment and armament, of which a variety were developed based on the records of the other Gundam Frames.
Although completed just before the end of the war, it still obtained remarkable military achievements in the battle against the mobile armors. In recognition of this, the family that owned the Gundam Dantalion was allowed to use the name "Zalmfort". Even now, 300 years later, the family continues to have a strong presence under the post-war Gjallarhorn and Gundam Dantalion remains the family’s symbol.
