An evil paramilitary organization calling itself COBRA has acquired a series of ICBM missiles, and threatens to launch them on all the major cities in the world unless the United Nations accedes to their demands for world domination. The Calico crew discovers the secret island base of COBRA, and are taken prisoner by the organization. They still manage to summon Godzilla to the island, and upon arriving, the Kaiju King battles and defeats the organization's large military arsenal. Upon reaching COBRA's nuclear reactor, Godzilla destroys it, thereby ending the organization's threat, and after rescuing his human allies, they see to it that the villains are arrested by a United Nations Task Force.
