''Gamera Super Monster'' is the last of the Showa Gamera movies, and is infamous for relying ''heavily'' on footage from not only the previous films, but other films like Galaxy Express 999. The plot concerns war-loving aliens from the distant planet Zanon invading the earth with an army of monsters (Gamera's previous opponents). To wipe out a trio of peaceful alien women living in secret amongst humanity, Zanon sends down their own alien babe to exterminate them. When young Keiichi explains to the three spacewomen about the legendary Gamera, they press him into action as earth's last chance against Xanon and their destructive monsters.

!! Gamera Super Monster contains the following tropes:

* {{Expy}}: To put it lightly, the ship the antagonist uses looks a ''lot'' like a [[StarWars Star Destroyer]].
* HeroicSacrifice: Gamera rams himself into the "Star Destroyer" at the end.
** Originally Gamera lived in the script, but when director Noriaki Yuasa saw the terrible cost-cutting measures Tokuma Publishing was taking on the film, he realized Gamera would never come back from the film, so he and writer Niisan Takahashi decided to kill him off. This is why everyone is still happy at the end: only rudimentary changes were made to the script's ending.
* RecycledScript: One of the main characters is [[Film/GameraVsGyaos Keiichi]], [[{{Film/GiantMonsterGamera}} a boy obsessed with turtles who is forced to get rid of his pet turtle, and believes it is Gamera.]] [[Film/GameraVsGuiron A evil space woman]] [[Film/GameraVsZigra is sent to kill our heroes]] [[Film/GameraVsViras and brainwashes Gamera.]] And that's not even counting the StockFootage.
* RunTheGauntlet: Gamera takes on all of his monster foes from previous movies. Via stock footage of course.
* ShesGotLegs: Giruge. And she KNOWS how to use them.
* StockFootage: Hoo boy. Nearly half of the film is this, and when it's not footage from previous films, it's footage from anime like ''Anime/SpaceBattleshipYamato''.
* TakeThat[=/=]WritingAroundTrademarks: During Gamera's BrainwashedAndCrazy attack on a city, he destroys a billboard advertising "[[Franchise/{{Godzilla}} Dogzilla]]".
