Godzilla vs. Destoroyah

After the death of Space Godzilla, Birth (or Bass)Island is found destroyed with Godzilla nowhere in sight. His adopted son, Little Godzilla, is presumed dead at first but later reveals himself as a larger and more powerful sub-adult due to the excess radiation Godzilla Junior. Godzilla, covered in glowing lava-like rashes, enters Hong Kong and destroys it. G-Force representatives hire college student Kenichi Yamane, adopted grandson of Dr. Yamane who witnessed the original Godzilla in 1954, to come work at the center in an attempt to unravel the mystery of Godzilla's condition.

Yamane suspects that due to his out of control radioactivity, Godzilla will soon explode, taking much of Japan with him. G-Force immediately deploys a flying combat vehicle outfitted with anti-nuclear cold weapons to forestall the event; the Super-X III. Meanwhile, in the area where the original Godzilla died, strange life forms begin to rise, and a host of deadly creatures called Destroyah begin wreaking havoc. Soil samples reveal that the existence of Destroyah is directly connected to the Oxygen Destroyer used against Godzilla in 1954, which mutated Precambrian era life forms. After several deadly skirmishes with the Japanese Self Defense Force, the Destroyah evolve beyond the JSDF's containment abilities and psychic Miki Saegusa must use her failing powers to lure Godzilla Junior to the area in an attempt to combat Destroyah in Tokyo. Godzilla, who is tracking his offspring, follows Junior and will soon arrive in as well, but complications arise. Due to his encounter with the Super-X III, Godzilla has now bypassed an explosion and will ultimately melt down once 1200 degrees Celsius has been reached; an event that will burn straight into the core of the planet and destroy all of Earth.

The first time the monsters fight, Junior is greviously wounded but manages to destroy his opponent. However, as Godzilla and Junior meet in Narita, Destroyah returns in his final form: a monstrous gargoyle-like creature. Swooping down upon the surprised monsters, Destroyah snatches the little Godzilla away; dropping the small creature from high above and killing him. Enraged, Godzilla attacks Destroyah and a back and forth battle ensues that destroys much of Tokyo. Born from the weapon that first defeated Godzilla, Destroyah shows an obvious advantage from the start, but Godzilla's runaway radioactivity has pushed the monster's power to unimagineable levels and he soon destroys his son's killer. Unwilling to die easily, Destroyah's body decomposes into many smaller Destroyah which attempt to swarm Godzilla from all sides, but the attack ends in futility.

Alone at last, Godzilla attempts to breath life into his fallen son but to no avail, and even as he grieves, Godzilla's heart continues to fail, causing even more pain within the monster. Suddenly, Destroyah returns in his final form for one last attack! The battle is fierce but short; enraged by the loss of his offspring and maddened by the pain within him, Godzilla drives Destroyah back to the brink of death as Tokyo is bathed in fire. As the battle reaches fever pitch, the ghastly creature attempts to flee, but just as Destroyah lifts off, the Super-X III attacks and disables the creature's wings, causing Destroyah to plummet back to earth where he explodes and is consumed in a fiery inferno at Godzilla's feet.

His son gone and his foe defeated, Godzilla stands alone and dying, but the human race cannot afford to give Godzilla a quiet funeral. As the monster begins to melt, the JSDF bombards the dying beast with a plethora of ice weapons, successfully neutralizing the immense heat that is given off and preventing Godzilla's remains from melting into the center of the Earth and igniting the planet.

The victory is a costly one however, for the radiation has made Tokyo an uninhabitable ghost town. Suddenly, radiation levels begin to drop, and from within the thinning smoke a roar can be heard. The younger Godzilla rises from the ashes a child no more. In death, Godzilla had passed on his excess radiation and life essence as a final gift to his son, reviving and mutating the next generation. The spitting image of his father, the new adult Godzilla flexes his claws and bellows a challenge to the world reborn to the next generation.
