[[caption-width-right:350:The G-Extermination Strategy... has gone horribly, horribly wrong.]]
The 24th entry of the ''Franchise/{{Godzilla}}'' franchise and the second of the Millennium era. Another ContinuityReboot (albeit with some BroadStrokes cues from ''Film/{{Godzilla 2000}}''), it's a direct sequel to the first film. It involves the return of the obscure Meganulon from ''{{Rodan}}'' and the introduction of Megaguirus, their queen and an addition to the tiny number of female monsters. Called ''Gojira tai Megagirasu Jī Shōmetsu Sakusen'' (''Godzilla x Megaguirus: The G Elimination Project War'') in Japan.

In a world where Godzilla never met his end to Doctor Serizawa's Oxygen Destroyer, his later attack on a Tokai village nuclear power plant forced the country to move to green energy. It isn't enough to power the country, so plasma energy is created. But 1996, Godzilla is attracted to it, and in his rampage, Kiriko Tsujimori's Major is killed. Swearing vengeance, Kiriko rises to an important position in newly formed G-Graspers and recruits independent technological engineer, Hajime Kudo. They plan to get rid of Godzilla through Dimension Tide, an artificial black hole that would swallow the King of the Monsters whole.

But in a test on an abandoned school, a portal is created and an egg is laid by a large insect that flies through it. A innocent boy moving to Tokyo unwittingly takes the egg; he is unable to keep it hidden, and dumps it in the sewer, where it floods Shibuya and unleashes the Meganulon upon the world. The Dimension Tide project gets derailed when the Meganulon metamorphose into Meganula and attack Godzilla to drain away his power. Godzilla escapes the black hole and moves toward Tokyo, where the Meganula who have taken his power give it to a monster that could take the King of the Monsters' place as the ultimate threat. Can Godzilla defeat the fast and wicked Megaguirus? And can the G-Graspers swallow Godzilla in the Dimension Tide when the satellite it's on begins to fall to Earth?

This film introduces the first human character to climb onto Godzilla's back in the main film franchise and begins the Millennium tradition of introducing older veterans in older, more authoritarian roles. Although it was well recieved by fans overall, the film tanked at the box office in Japan, selling fewer tickets than any Godzilla movie since ''Film/TerrorOfMechagodzilla''. Like ''Film/GodzillaVsBiollante'', this set the tone for reintroducing older, popular monsters in future films.

----
!!The film provides examples of
* ActionGirl: Kiriko Tsujimori, who climbs onto a swimming Godzilla and risks her life so the failing Dimension Tide would target Godzilla. Megaguirus as well is a nonhuman example.
* CorruptCorporateExecutive: Motohiko Sugiura, who admits that a secret plasma energy generator was housed in the science institute...which was the reason for Godzilla's attack in the first place. He does say that the generator was shut down, but either way, Godzilla knew about it.
* TheEndOrIsIt: Godzilla's been defeated! The Megulon are gone, and so is Megaguiurus! But what's been causing earthquakes? IT'S ''GODZILLA!!!''
* ExtremeGraphicalRepresentation: The program Kudo uses to fix all the faltering tech is represented by a little man in a jetpack flying through a digital space and shooting corrupted data patches with a laser.
* GiantFlyer: Megaguirus.
* HellIsThatNoise: Megaguirus' shriek.
* ImplacableMan: Godzilla himself. Seriously, being attacked by energy sucking bugs, and being hit with a freaking ''miniature black hole'' is nothing to him in his quest for a secret energy reactor.
* KillSat: The Dimension Tide, designed to be mounted on a satellite, fires ''black holes''. It would be overkill against any foe but Godzilla.
* LightningBruiser: Megaguirus is able to dodge and weave around Godzilla's attacks, close the distance, then fight him to a standstill up close. It's only when Godzilla brings out his atomic breath that [[KillItWithFire she goes down.]]
* OhCrap: Megaguirus has two. The first is when Godzilla jumps on her, and the second one is when Godzilla finally catches her tail... in his ''mouth''.
* PrehensileTail: This is the ONLY film in the Godzilla franchise in which Godzilla possesses one of these. [[spoiler:He uses this it to catch Megaguirus in mid-flight just as she's about to sting him]].
* {{Retcon}}: Considering that this is the same Godzilla from ''Film/{{Gojira}}'', he does not die at the hands of Daisuke Serizawa's Oxygen Destroyer (nor if that existed).
* SlasherSmile: Megaguirus seems to sport one at various moments during her battle with Godzilla.
* SugarAndIcePersonality: Kiriko, who's quite cool to the flirtatious Kudo and very focused on the mission. However, she's kind to children, respectful of Professsor Yoshizawa, and doesn't want to endanger her teammates. Also, it's hinted she begins to respect Kudo, and maybe even return his feelings.
* TeamMom: Professor Yoshizawa. Warm and kind, she's a prominent figure in the Dimension Tide project and has the respect of the noncomforming Kudo and the cool Kiriko. She even breaks up a fight between the two when Dimension Tide first fails.
* TooDumbToLive: The squad who tries taking on Godzilla with ''bazookas.'' You're going to take a weapon designed to destroy tanks, and use it against something that has a reputation for destroying tanks by the hundreds?
