* EnsembleDarkhorse:
** Despite the movie itself not being well received, Megalon himself was very much well accepted by the fans for having a cool design and some decent fighting ability. It helps he has appeared in the [[VideoGame/GodzillaDestroyAllMonstersMelee Atari/Pipeworks Godzilla games]] as an easy to pickup and play fighter.
** Gigan's status as one no doubt was the reason for his inclusion in this title.
* HoYay: Goro and Hiroshi are often interpreted as a gay couple. That we're ''never'' given a solid explanation of how they even know each other doesn't help.
* MemeticMutation:
** The ''Series/MysteryScienceTheater3000'' version certainly helped. It's hard to discuss Jet Jaguar without being met by a cry of "[[WellDoneSonGuy HE MOTHER NEVER REALLY LOVE HIM]]."
** The overly enthusiastic "Punch! Punch! Punch!" from the Jet Jaguar song became its own minor meme, even getting an EasterEgg reference in the ViralMarketing to [[Film/{{Godzilla2014}} the 2014 Godzilla]].
** Godzilla's tail-slide against Megalon. So good, he does it TWICE, and it was later included as an unlockable move in ''Godzilla: The Game''.
* {{Narm}} / NarmCharm: Godzilla and Jet Jaguar using hand signals to communicate can be one or the other, depending on your mood.
** Megalon and Gigan as well; they even do a high five/brofist at one point!
* RescuedFromTheScrappyHeap: Jet Jaguar in subsequent Godzilla fighting games where he's a fun character to use as well as his use in IDW's Rules of the Earth comic.
* TheScrappy: Rokuro was annoying enough in the original, but the dub provides him with perhaps the most awful, screechy voice of any Godzilla kid.
* SerialNumbersFiledOff: A common rumor is that part of why Jet Jaguar didn't get off the ground was because the copyright owners of ''Ultraman'' took umbrage. If that's true, they must have buried the hatchet at some point.
* SignatureScene: The [[SoBadItsGood hilariously]], [[ArtisticLicensePhysics physics-defying]] [[https://www.youtube.com/watch?v=JuEa6Hum0b4 dropkick sequence]].
* SoBadItsGood: Commonly regarded as one of the worst Godzilla movies, the film still has a fairly sizable fan following largely due to this trope.
* SpecialEffectsFailure: Many, [[SignatureScene but most notably]] [[ArtisticLicensePhysics Godzilla's]] [[RunningGag awe-inspiring]] [[ArtisticLicenseMartialArts tail-slide dropkick to Megalon]].
** Gigan got hit with this. In the new footage, Gigan's mouth and mandibles rarely move when he roars, and the mandibles are hanging at an angle the entire time like the internal supports are broken. He also never uses his belly buzzsaw, and the individual blades are all set at weird angles.
*** Look carefully and you'll find Gigan sucker-swipe in Godzilla from behind and slice open the top of his head with his buzzsaw. A spray of blood can even be seen before Godzilla falls down.
* VisualEffectsOfAwesome: All that being said, a scene where Megalon destroys a dam is very impressive and obviously ate up a considerable chunk of the film's budget.
* WTHCostumingDepartment: Why does Godzilla have irises?
** Cementing Godzilla's complete change into a protector of Earth, this version of his suit (used from here until ''Film/TerrorOfMechagodzilla''), especially the head, resembles [[Franchise/TheMuppets Kermit the Frog]].
*** [[UglyCute And]] he's [[CuteBruiser CUTE!]]
