* SugarWiki/AwesomeMusic: Akira Ifukube sent both Godzilla and himself out with a bang, as this was Ifukube's last film score before he retired. In an interview, Ifukube said that composing music for Godzilla's death was almost like composing music for his own death.
* EnsembleDarkhorse: Though he's the main villain, as a Kaiju overall, Destroyah has quite a large following thanks to this movie. Many saw him as an insanely dark and cruel monster that gave Godzilla one hell of a show.
* FridgeBrilliance: Remember the line "Godzilla never does destroy Japan"? Remember Junior's GentleGiant nature? Now the line has a new meaning due to the fuckup by the Futurians. The reason why JapanTakesOverTheWorld is maybe due to Junior being a gentle giant in the movie.
** Destoroyah was invulnerable to the military freezing weapons after his first OneWingedAngel transformation, but it's ultimately what does him in. Why? Because he'd just been super-heated by Godzilla's meltdown. His super-heated armor was rapidly cooled, subjecting him to thermal shock. He was probably reduced to a fragile wreck before he hit the ground, allowing the impact to finish him.
*** More brilliance: The above means that Godzilla ultimately gets the credit for defeating Destoroyah, even though he didn't deliver the killing blow.
* MemeticMutation: DESTOROYAH!!! In the Godzillathon review of this movie, James Rolfe always says "DESTOROYAH!" whenever he addresses him.
** He even does this in the AVGN episode "Godzilla".
* TearJerker: Junior's death, and Godzilla's failed attempt to revive him. The music for this sequence is appropriately titled ''Roar of Sadness''. Also, Godzilla's death.
** Hell, even the events leading up to Godzilla Jr.'s death was a TearJerker when you really think about them. Up until the final battle, Godzilla was desperately in search of his son, following him from location to location. Godzilla apparently KNEW he was dying, and like any father on his death bed, wanted to see his son one last time. And just as they're about to embrace, [[KickTheDog Destroyah breaks up the reunion and kills Junior.]] No wonder Godzilla got so pissed and started beating Destroyah so savagely. [[DoNotGoGentle Godzilla had nothing left to lose.]]
* TheyWastedAPerfectlyGoodPlot: A scene featuring Godzilla giving Destoroyah a NoHoldsBarredBeatdown as dies was removed because it lessened the impact of Godzilla's death, though it's still pretty satisfying to watch.
** That ending was shot as a dupe and never meant to be used. Wires and filming equipment can be seen in many of the shots, betraying its hastily put together nature.
