In 1999, something was trucked out of Guanshan City. A few days later, Godzilla landed in Guanshan, and Tesheng self-Defense Forces deployed to fight it. In the battle, the self-defense force home Chengqian (Yumiko) accidentally killed his comrade-in-arms second Lieutenant Ye Shan (Senmo Shen er), but he survived and was sent to the information department. On the other hand, the Japanese government, under the command of Prime Minister Toshihiko Mizuno (Kumi Mizuno), summoned scientists such as Takahara Deguang (Miyama) to study G weapons against Godzilla. Based on the original Godzilla bones excavated in Guanshan, it took them four years to make the mechanical Godzilla-3 machine dragon. Prime Minister Takeshi resigned, and Igarashi Fumihiko Falcon, head of the Office of Science and Technology (Bin Nakao), became the new prime minister. At the same time, Qian was sent to the machine dragon team as the operator of the machine dragon. Just as the machine dragon was ready to test the maneuver, Godzilla reappeared in Tokyo Bay. The machine dragon rushed to the scene to fight with Godzilla, but because of Godzilla's roar, he awakened the soul of the beast and suddenly left, causing great damage in the city. In order to improve the machine dragon, Yuhara changed the alkali structure of the machine dragon DNA computer, so that the machine dragon will no longer be disturbed by Godzilla calls.
