History Film / GodzillaAgainstMechagodzilla

* DubInducedPlotHole: The English dub states that Mothra was ''destroyed'' by the heat ray, whereas in the Japanese version they simply said that it was used against her. This naturally makes the sequel rather awkward.

Kiryu eventually runs out of power, but the damage to the project's reputation has been done. Kiryu is put into temporary retirement. Unfortunately, Godzilla returns days later, and only after setting fire to a significant portion of Tokyo does the Prime Minister authorize Kiryu's usage. During the battle, Kiryu, remotely controlled by Akane from a nearby airplane, kicks Godzilla's ass. Just when it seems that Godzilla is in a position for the absolute-zero cannon to be used, the monster king stops playing possum and damages Kiryu right before the freezing gun is fired, causing massive property damage. To make things worse, Kiryu has also run out of power.

To solve this problem, Akane leaves the plane and enters Kiryu to control him from the inside while he receives power from all over Japan. Meanwhile, her comrades and the rest of the JSDF attempt to keep Godzilla occupied. Soon, Kiryu is back in action, but before he can even move, Godzilla attacks the cyborg, knocking Akane briefly unconscious. Before Godzilla can finish both Akane and Kiryu, one of Akane's fellow pilots, Hayama, flies his plane into Godzilla's mouth to stop him. After she regains consciousness, Akane rescues her fellow pilot and flies over the ocean with Godzilla in tow while holding his mouth shut as she prepares to use the absolute-zero cannon. The weapon is finally used after falling into the ocean, but Godzilla survives and swims away, a massive scar on his chest showing the power of the weapon. Out of power and unable to do anything, Akane stands atop Kiryu's shoulder and watches her enemy retreat.

** Akane is one to Kiriko Tsujimori from ''Film/GodzillaVsMegaguirus'' due to both characters watching him decimate their platoons in the late 1990s and wanting to avenge their fallen comrades by taking the big guy out. They're also both aloof and distant to the male protagonists who eventually get them to [[DefrostingIceQueen lighten up]].

** Both also cause loyalty issues for the heroic monster, with Zilla Jr. briefly siding with his biological father and Kiryu briefly turning against humanity after their first encounter with each monster.

* SurprisinglyRealisticOutcome: Oh, boy is there ever.
** When Project KIRYU is first announced, several of Japan's neighbors are nervous due to the weapon's clearly offensive nature (Japan is not officially allowed an offensive military, having used their last one to start World War II). The PM must publicly state the machine is designed for dealing with giant monsters only, and that Japan has no interest in building an empire.
** After Kiryu [[spoiler: goes rogue]], people begin questioning whether or not it was a good idea for the AMF to even so much as ''consider'' building something like that.
** There is no OmnidisciplinaryScientist but several brought together for specific parts of Kiryu. One for how to power the whole thing, one on artificial life, one for software, one for the absolute zero cannon and so on.

--> Togashi (Japanese): That's the name of the anti-Godzilla robot. It's a mechanical dragon.
--> Togashi (English): That's what they've called it. We're in charge of the weapon: Mechagodzilla.

** [[ContinuityPorn It goes way beyond that]]. According to [[AllThereInTheManual a Toho published guidebook]], ''Film/{{Rodan}}'' (1956), ''Film/VaranTheUnbelievable'' (1957), ''Film/TheMysterians'' (1958), ''Film/{{Gorath}}'' (1962), ''Film/{{Dogora}}'' (1964), ''Film/FrankensteinConquersTheWorld'' (1965) and ''Film/KingKongEscapes'' (1967) are all in continuity with this movie and it's sequel.

* InterContinuityCrossover: Both ''Film/{{Mothra}}'' (1961) and ''Film/WarOfTheGargantuas'' (1966) are mentioned and explicitly referenced in the film. [[Film/GodzillaTokyoSos It's sequel]] doubles as a DistantSequel to the former.
