-> ''"Listen, I've done some crazy things in my life, but I've '''never''' stuck my head inside of a hornet's nest!"''
-->-- '''Yoshimura''' to Yata, in the Titan Productions dub of the Walter-Reade TV version.

Number seven in the long running ''Franchise/{{Godzilla}}'' series and more well known under the title ''Godzilla vs the Sea Monster'', this film started [[WhatCouldHaveBeen life as a]] ''Film/KingKong'' project until the proposal was rejected in favor of ''Film/KingKongEscapes''. Not wanting to put the script or monster costumes to waste, the film switched stars to Godzilla. Known in Japan as ''Gojira, Ebira, Mosura Nankai no Daikettō''.

The film begins with a young man, Yata, becoming lost at sea. His brother Ryota, certain that he's still alive out there sets out on a stolen yacht with two friends and a bank robber to search for him. On their excursion, they narrowly avoid destruction at the hands of Ebirah, a colossal crustacean guarding an island base home to a terrorist syndicate called the Red Bamboo. Using a special chemical, the Red Bamboo are able to repel their ships from Ebirah's wrath and have enslaved the natives of nearby Infant Island to produce the stuff. Evading capture, Ryota and crew meet a young native woman Dayo, who brings them to a cave on the island where Godzilla is currently slumbering. A plan is hatched to wake Godzilla with a lightning rod in order to get rid of Ebirah and the Red Bamboo and the slaves to escape and summon Mothra in order to rescue them.

!!The film provides examples of

* AnArmAndALeg: Godzilla rips off Ebirah's claws during their second battle
* AwakeningTheSleepingGiant: Literally! Godzilla is not on any side of the conflict, and is just a neutral third party tucked away in a deep sleep on the island. Once he wakes up, everything goes absolutely haywire for the previously untouchable Red Bamboo as neither they nor their crab are equipped to handle the radioactive lizard.
* BottleEpisode: The bulk of the film takes place on an island with no huge city sets and the ocean. Though there is an enemy fortress for Godzilla to stomp on.
* ChronicHeroSyndrome: According to Ryota, Yata always tries to help people who are in trouble.
* ComicBookMoviesDontUseCodenames: Neither the Red Bamboo or Ebirah are referred to by name in the Titan dub.
* TheDragon: Captain Ryuui to the Red Bamboo commander and Ebirah to the Red Bamboo.
* DubNameChange: Captain Ryuui is renamed as "Commander Yamoto" in the English version.
* EyePatchOfPower: Captain Ryuui.
* GiantEnemyCrab: Ebirah, though he's more of a Giant Enemy Lobster, or if you go by the name itself, a shrimp.
* GodzillaThreshold: The main characters decides to awaken Godzilla by using lightning to face off Ebirah and Red Bamboo. It arguably works too well as Godzilla goes thrashing their base before having a second round with Ebirah.
* GoodForBad: The slaves make the Red Bamboo a batch of the Ebirah-repelling liquid that's too weak to do any good, resulting in their boat being destroyed when they try to escape the island.
* MassOhCrap: The heroes collectively gasp in horror once they realize they happen to be sharing a cave with something far worse than either the Red Bamboo or the GiantEnemyCrab: Godzilla.
* MobileShrubbery: The heroes adopt this strategy to sneak into the Red Bamboo base, aided by the additional ploy of bringing along a captive bird to release if anyone gets suspicious.
* MsFanservice: Dayo. She is so sexy that even the King of the Monsters himself is entranced by her.
* NebulousEvilOrganization: The Red Bamboo. Beyond being [[AtomicHate nuclear-armed]] FarEastAsianTerrorists [[SlaveryIsASpecialKindOfEvil that like to use slaves]], nothing is really specified about them.
* NeverTrustATrailer: Or the posters for that matter. Godzilla tussles with Mothra briefly out of just being a curmudgeony jerk it seems, but there's no three way battle between the leading monsters.
* NominalHero: Godzilla plays a big role in thwarting the villains, but only because they're an annoyance. The heroes' plight means nothing to him and he barely pays them any mind.
* OutOfCharacter: Godzilla's behavior patterns. This is clearly evident when he first sees Dayo, and he certainly did not care about humans since his first appearance in ''Film/GodzillaRaidsAgain''. Partly justified when the role was originally given to King Kong.
* SelfDestructMechanism: When Godzilla starts thrashing around the place, the bad guys set a nuclear detonator to destroy the entire island.
* ShipTease: Notable in that this is the only film where Godzilla ''ever'' displays interest in a human, but that's what happens when he catches sight of Dayo, turns docile immediately and nods off. Dayo herself takes a shine to the big guy from the incident and even expresses some rare sympathy for him at the end. This is mostly a holdover from the film's original vision as a King Kong vehicle.
* SummonBiggerFish: The survivors and slaves can't hope to defeat Red Bamboo or Ebirah by themselves, so they awaken an even bigger monster to the job for them.
* TennisBoss: Godzilla and Ebirah volley a boulder back and forth at each other in their first encounter.
* VillainsOutShopping: While not exactly villainous here, up until this point, Godzilla was a major threat to humanity. Here though, it can be interpreted that he's just taking a vacation since throughout the first half of us seeing him, he's just napping.
