It is unknown whether Diagoro was captured and taken to Japan, or if it was just born there to begin with. Either way, Diagoro's Mother made her presence felt to the country. Stone and steel were turned to mangled piles as she stormed though the industrial cities in her path, protecting her baby from the corrupting fingers of humankind. Normal weapons proved useless against her. It wasn't until the heavy Intercontinental missiles were brought out did her reign end. Even her power could not stand against thousands of pounds of explosives, and so, she was killed. Taken from her own flesh and blood in the worst way possible.
