Editing Terror of Mechagodzilla (section)

==Plot==
Following [[Mechagodzilla]]'s and the Simeons' defeat by [[Godzilla (Showa)|Godzilla]] and [[Okinawa Prefecture|Okinawa]]n guardian monster King Caesar,{{efn|As depicted in ''[[Godzilla vs. Mechagodzilla]]'' (1974).}} [[Interpol]] agents search for Mechagodzilla's remains at the bottom of the Okinawan Sea in the hopes of gathering information on the Simeons. Their [[submarine]] is attacked by a giant marine dinosaur they name Titanosaurus and the crew vanishes.

Interpol launches an investigation into the incident. With the help of [[marine biologist]] Akira Ichinose, they trace Titanosaurus to a reclusive mad scientist named Shinzô Mafune, who wants to destroy mankind. While the group visits Mafune's home, they meet his daughter, Katsura, who secretly underwent surgery and became a [[cyborg]] after she was injured during one of her father's experiments. Katsura claims her father is dead and that she burned his notes about Titanosaurus. Mafune is visited by Tsuda, an aide to the Simeon supreme leader Mugal, who is leading a project to rebuild Mechagodzilla into Mechagodzilla 2. Mugal offers the Simeons' services to Mafune so that their respective monsters can wipe out mankind. A control device for Mechagodzilla 2 is implanted into Katsura.

Ichinose falls in love with Katsura and unwittingly gives her Interpol's information on the Simeons, Mechagodzilla, and Titanosaurus. An impatient Mafune releases Titanosaurus on [[Yokosuka]] without the Simeons' permission. While Interpol discovers Titanosaurus is vulnerable to supersonic waves, Katsura destroys their supersonic wave oscillator. Godzilla arrives and easily defeats Titanosaurus, causing the latter to retreat.

When Ichinose visits Katsura, the Simeons capture him and unleash Mechagodzilla 2 and Titanosaurus on [[Tokyo]]. Interpol repairs their wave oscillator and the Japanese armed forces struggle to fend off the monsters. Godzilla arrives but is outmatched until Interpol distracts Titanosaurus with the repaired wave oscillator, allowing Godzilla to focus on Mechagodzilla 2. Interpol agents infiltrate the Simeons' hideout, rescue Ichinose, and kill Mafune and many of the Simeons. The remaining Simeons attempt to escape, but Godzilla shoots down their ships with atomic breath. The wounded Katsura shoots herself to disables Mechagodzilla 2's control device. Godzilla destroys Mechagodzilla 2, but Katsura dies in Ichinose's arms. With help from Interpol, Godzilla defeats Titanosaurus and returns to the ocean.
