Godzilla: Tokyo S.O.S: In 2004, Kiryu is undergoing repair modifications after its battle with Godzilla one year earlier. Prime Minister Hayato Igarashi accepts Lead Scientist Yoshito Chujo's choice to replace the Absolute Zero Cannon with a powerful Tri-Maser. The Shobijin (Mothra's twin fairies) warn the Japanese government that Godzilla continues returning to Japan because they used the original Godzilla's bones in Kiryu's design. If they return the bones to the bottom of the sea, Mothra would gladly take Kiryu's place in defending Japan, but if they do not, Mothra will declare war on humanity. Soon enough, Kamoebas, a giant mata mata turtle, is found washed ashore on a Japanese beach. It is determined by the wounds on Kamoebas' neck that Godzilla killed it. Godzilla and Mothra fight, but Godzilla seems to have the upper hand. With the repairs finished just in time, Kiryu manages to even the odds, but Godzilla still manages to knock both it and Mothra out. Meanwhile, on Infant Island, two twin Mothra larvae hatch from Mothra's egg, and rush to help their mother. As Kiryu undergoes repairs again, the larvae try to hold Godzilla off, but Mothra sacrifices herself by flying in the way of Godzilla's atomic breath, saving the larvae. Just in time, Yoshito and the humans repair Kiryu, who stabs Godzilla's chest with a drill, causing Godzilla to bleed and roar in pain. The larvae begin to bind Godzilla up in silk. Just as Kiryu's pilot, Azusa Kisaragi, receives the order by Igarashi to destroy Godzilla before the Kiryu project is scrapped, Kiryu's soul is reawakened through Godzilla's roar. The cyborg lifts Godzilla and secures its grip with cables. Kiryu then uses its boosters to carry itself and Godzilla to the bottom of the ocean. In the film's post-credits scene, in an undisclosed location, a laboratory is shown, filled with canisters that contain the DNA of numerous Toho kaiju. It is stated in the Japanese version via a narrator announcing that a "bio-formation" experiment involving an "extinct subject" is about to take place, implying that the JXSDF plans to create another mecha or kaiju-based superweapon, which could mean that Godzilla or another monster could appear once again. In the Japanese version, Godzilla and Kiryu are seen one more time, roaring as they descend into the ocean. Godzilla Final Wars: Years after an initial attack of Tokyo in 1954, Godzilla is entrapped under ice in Antarctica after a battle with the original Gotengo. In later years, environmental disasters cause the appearance of giant monsters and superhumans, dubbed "mutants", who are then recruited into the Earth Defense Force (EDF) to battle the monsters. An upgraded Gotengo, commanded by Captain Gordon, battles and destroys Manda, but the ship is wrecked in the process and its captain Douglas Gordon is suspended from the EDF. Mutant soldier Shinichi Ozaki is tasked with guarding a U.N. biologist, Dr. Miyuki Otonashi, who is sent to study a mummified monster. They are teleported to Infant Island where they encounter the Shobijin, fairies of Mothra, who reveal the mummified monster as Gigan, an alien cyborg sent to destroy the Earth who was ultimately defeated by Mothra. They warn that a battle between good and evil will happen soon and that Ozaki must choose a side. Giant monsters begin attacking several major cities. The EDF engage the creatures, who mysteriously vanish at the same moment when an alien mothership appears over Tokyo. The aliens, named Xiliens, warn that an incoming planet called "Gorath" will soon impact the Earth. A peace pact is signed between Earth and the Xiliens. Meanwhile, Minilla, Godzilla's son, is found in the forest by a boy and his grandfather. Distrusting the Xiliens, Ozaki, Miyuki, and her sister, Anna discover that Gorath they saw is actually a hologram and that the aliens have replaced several members of the EDF with duplicates. After their kind is exposed, killing his superior to assume command, the Xilien Controller X reveals their plans to use humans as a food source while taking control of all the mutants save Ozaki. X also has the monsters placed under his control and awakens Gigan to have them to wipe out the EDF. The group escapes with Gigan pursuing them, Gordon convincing them to travel to Antarctica to release Godzilla who easily destroys Gigan. The Gotengo then guides Godzilla into battle with the other monsters and returns to Tokyo to engage the Xiliens. After penetrating the mothership, the group is captured and brought before X as he has summoned Gorath to Earth. Though Godzilla destroys Gorath just before it crashes, it unleashes Monster X and the two monsters battle. An upgraded Gigan aids Monster X, but is intercepted by Mothra, who is gravely wounded while managing to destroy the cyborg. In the Xilien ship, as a fight breaks out while unable to take control of the human due to the Shobijins' blessing, X reveals that both he and Ozaki are superior beings known are "Keizers". X is fatally wounded, but he triggers the ship's self-destruct as the group fall back to the Gotengo moments before the mothership explodes. Godzilla and Monster X continue their battle as the latter transforms into its true form, Keizer Ghidorah. Keizer Ghidorah initially gets the upper-hand but Godzilla emerges victorious in the end. Minilla shows up at the scene and convinces Godzilla not to destroy the Gotengo. The survivors watch Godzilla and Minilla return to the ocean.
