Burning Godzilla

In 1996, a nuclear reaction in Godzilla's heart ignited uranium deposits on Birth Island, causing the island, along with Godzilla and his adopted son, to vanish in a fiery explosion. Godzilla soon resurfaced in Hong Kong, now covered in glowing red rashes and called Burning Godzilla (バーニングゴジラ Bāningu Gojira). Godzilla annihilated the city with his red atomic breath and eventually disappeared out to sea. During a meeting the next day, G-Force discussed Godzilla's appearance. Professor Marvin, an American scientist employed by the United Nations Godzilla Countermeasures Center, suggested that something had happened to Godzilla's heart, which was essentially a biological nuclear reactor. Marvin suggested G-Force seek out college student Kenkichi Yamane, who had written a thesis paper about Godzilla's physiology. Kenichi, the grandson of Kyohei Yamane, revealed that his father Shinkichi devoted his life to studying Godzilla, but he himself thought of Godzilla as a hobby and had no interest on studying him professionally. However, upon learning he would be working with Miki Saegusa, Kenichi readily agreed to join G-Force. Kenichi concluded that the Birth Island explosion had caused Godzilla to absorb a substantial amount of radiation, causing the nuclear fission in his heart to go out of control. Kenichi said that it if Godzilla continued to increase in power, he would explode, igniting the atmosphere and vaporizing the Earth. Kenichi stated that there was only one way to kill Godzilla before this happened, the same way the first Godzilla in 1954 was killed: the Oxygen Destroyer. Kenichi and his sister Yukari sought out Kensaku Ijuin, a physicist who had developed an invention similar to the Oxygen Destroyer called Micro-Oxygen, and asked him to create a new Oxygen Destroyer. Ijuin refused, warning that the Oxygen Destroyer had mutated a colony of crustaceans from the Precambrian era and that these crustaceans had evolved and started to come ashore. Without the Oxygen Destroyer and knowing a direct attack on Godzilla could cause him to explode, G-Force turned to the Super X3, the third vehicle in the Super X line, which was armed with cadmium shells and freezer weapons. The Super X3 engaged Godzilla in the Bungo Channel as he approached the Ikata Nuclear Power Plant. The Super X3's freezer weapons successfully lowered Godzilla's core temperature and encased him in ice. As Godzilla thawed, the fission in his heart appeared to be reducing, and humanity breathed a sigh of relief.

Meanwhile, Godzilla's adopted son surfaced at Omae Cove, and had been mutated into a sub-adult Godzilla by the Birth Island explosion. Godzilla Junior, as G-Force Commander Takaki Aso now dubbed him, appeared to be heading back to his nest on Adonoa Island. G-Force soon learned some troubling news, as although Godzilla's fission had been brought under control, his reactor was now overheating. Now, Godzilla would undergo a nuclear meltdown, which would cause him to burn into the Earth's core and destroy the planet. G-Force had no clue about how to prevent this worst-case scenario, while Godzilla would melt down in less than a week. After learning that Godzilla was following Junior, Kenkichi Yamane proposed a desperate plan: use Junior to lure Godzilla to Tokyo, where the crustaceans mutated by the Oxygen Destroyer had merged into a giant monster called Destoroyah. Kenichi believed that since Destoroyah was the living Oxygen Destroyer, it was the only thing that could kill Godzilla. Miki Saegusa reluctantly used her telepathy to change Junior's course and bring him to Tokyo. Junior was attacked by Destoroyah, but managed to defeat him. When Godzilla appeared in Tokyo Bay, Dr. Ijuin proposed a new plan to use G-Force's freezer weapons to freeze Godzilla as he melted down in order to minimize the damage. The Super X3 and G-Force's new CLT-95 ULT Maser Cannons, along with modified MBT-MB92s and MBAW-93s, were sent to Tokyo in anticipation of Godzilla's meltdown, which would occur once his core temperature reached 1200 degrees Celsius.

Godzilla Junior reborn as the new Godzilla at the end of Godzilla vs. Destoroyah As Godzilla and Godzilla Junior reunited near Haneda Airport, Destoroyah appeared in his demonic final form and blasted Godzilla with his Micro-Oxygen beam. Destoroyah grabbed Junior and flew high into the air, dropping him onto the Ariake Coliseum and blasting him with his beam until he appeared to die. Godzilla roared out in grief, but Destoroyah wrapped his tail around Godzilla's neck and dragged him into Tokyo Bay, bellowing maniacally. Determined to avenge his son, Godzilla walked back onto land and confronted Destoroyah. Destoroyah sliced into Godzilla's flesh with his laser horn, leaving a huge scar across Godzilla's chest. Godzilla retaliated by firing his atomic breath at Destoroyah's chest, opening a wound in the beast's chest cavity. Godzilla fired into the open wound, causing Destoroyah to vomit blood and collapse, disintegrating into a white mist. Destoroyah was not defeated, as several of the creature's smaller aggregate forms swarmed Godzilla. Using a nuclear pulse, Godzilla defeated the aggregate Destoroyahs. His temperature climbing, Godzilla approached his fallen son. Godzilla tried to breathe energy back into Junior, whose eyes briefly opened. Junior stared up at his father before closing his eyes and passing away. Godzilla's dorsal fins began to flash as he roared and fired his atomic breath into the air. As Godzilla grieved, Destoroyah returned in his final form and grabbed Godzilla by the neck with his tail once again, dragging him to the outskirts of the city. Godzilla got right back to his feet and approached Destoroyah, ready for one final confrontation with his son's killer. Godzilla's temperature began to climb to critical levels, as his dorsal plates started to melt. Giving off waves of intense heat, Godzilla fired his hyper spiral ray at Destoroyah, blasting off part of his head and wounding his shoulder. Godzilla and his atomic breath caused the area around Destoroyah to erupt in flames, until Destoroyah could no longer withstand the heat. Destoroyah began to take flight, but G-Force opened fire with their freezer weapons, freezing and shredding the beast's wings and sending him plummeting to the superheated ground. Destoroyah struck the ground and instantly exploded into a white mist, which soon dissipated. His son's killer finally dead, Godzilla stood silently as his temperature reached critical, ready to die in peace. G-Force opened fire on Godzilla with all their freezer weapons as he melted down. Finally, Godzilla's heart burst, and his outer body and skeleton melted away to nothing. G-Force prevented Godzilla's meltdown from destroying the planet, but they could not prevent him from releasing catastrophic levels of radiation into the air. When it appeared Tokyo would be rendered uninhabitable, all of the radiation suddenly vanished. Soon, Godzilla Junior was visible through the smoke, revived and transformed into a new Godzilla, ready to take up his father's mantle.
