Meanwhile, Godzilla awakens from his encounter with the Super X III. With the runaway nuclear reactions in his heart continuing to progress, Godzilla's condition has worsened to the point that he will suffer a bodily meltdown which could potentially destroy the planet through a China syndrome-like incident. Miki locates Little Godzilla - now named Godzilla Junior - who has grown significantly as a result of the destruction of Birth Island and resembles the larger Godzilla very closely. Miki is instructed to telepathically lure Godzilla Junior to Tokyo, hoping that Godzilla will follow and be killed by Destoroyah. Junior arrives and battles Destoroyah's Aggregate, who severely injures Junior by sending micro oxygen into the wound, and Flying form, who is seemingly defeated after being blown into an electrical plant. Godzilla arrives at Haneda Airport and reunites with Godzilla Junior, only for the electrical plant at which Destoroyah was defeated to suddenly explode, revealing Destoroyah's final, Perfect form, which was created after the aggregate absorbed Junior's DNA during the previous fight. Before Godzilla can fight Destoroyah, Destoroyah kills Junior by dropping him from a great height onto Ariake Coliseum and blasting him with his Micro-Oxygen beam leaving Miki and Godzilla devastated over Junior's death. After being dragged away from the location of Junior by Destoroyah, Godzilla manages to subdue his adversary for just long enough to reach the airport for a second time. Godzilla mournfully approaches the body of Junior.
