Yamata no Orochi no Gyakushu (1985)

Yamata no Orochi no Gyakushu 1985 / 八岐之大蛇の逆襲 1985 / Eight-Headed Giant Serpent's Counterattack , Yamata no Orochi no Gyakushū

This film was Daicon's epic parody of the many classic daikaiju (giant monster) films and featured a more biomechanical-looking version of the mythical eight-headed serpent, the Orochi. This one was created by aliens, which had invaded Earth in ancient times. 2000 years later, they dispatch the Orochi again to destroy Japan and the rest of the world. Only a team of the Japan Self-Defense Forces and a scientist (two other staples in the daikaiju genre), can destroy it. (Source: Wikipedia)
