Godzilla Tokyo S.O.S

plot: Kiryu is undergoing repair modifications after its battle with Godzilla. 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 sea 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 manages to knock out both monsters.

Meanwhile, on Infant Island, two twin Mothra larvae hatch from Mothra's egg, and rush to help their mother. As Kiryu was being repaired, the larvae try to hold Godzilla off, but Mothra is killed by Godzilla's atomic breath while trying to save her children. Just in time, Yoshito and the humans repair Kiryu, who stabs him in Godzilla's chest with a drill. Godzilla roars in pain, and the larvae begin to bind him up in web. 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 re-awakened through Godzilla's roar. The cyborg lifts Godzilla and secures themselves 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 containers that are filled with the DNA of numerous Toho kaiju. Therefore, the threat remains.

In my opion this is a very good robot movie I like how Kiryu/Mechagodzilla was portrayed as a robot super hero and how he assited mothra in fighting off the evil godzilla and how Kiryu/Mechagodzilla sacrifed him self for japan
