The Weapon Digimon (武器デジモン Buki Dejimon?), also known as Legend-Arms (Ｌｅｇｅｎｄ－Ａｒｍｓ Legend-Arms?), are unique Digimon who carry out transformations into giant, peerless weapons based on the master they choose, and which according to legend, "if held by an angel will save the world, and if held by a demon will destroy the world." The Weapon Digimon used their strongest member, Spadamon, to repel invaders, but when its powers and memories were sealed and it was hidden in a different Zone, the Zone was occupied by the invading army, and the defeated Weapon Digimon went into stasis.
