Once feared by humanity, Godzilla has proven himself to be a defender of Earth, against threats from outer space, other dimensions and even Earth itself. The robotic imposter Mechagodzilla and the pollution-loving spores that became Hedorah, the Smog Monster, both had their origins off-planet. Now, when Godzilla needs help, humanity stands ready to assist, with tanks, scientists, and even the size-changing robot Jet Jaguar.
