History Film / GodzillaVsHedorah

* DisneyAcidSequence: There are a number of psychedelic instances in this film. They range from animation sequences with living factories and Hedorah drinking oil from a tanker as if it were a bottle of soda, to Yukio hallucinating that the guests at the party all had fish heads.

* DisneyAcidSequence: There are a number of psychedelic instances in this film. They range from animation sequences with living factories to a guy hallucinating fish heads on other humans.

* GeniusBruiser: While Godzilla's as smart as he always is, Hedorah comes an extremely close second when it comes to intelligence. In fact, with [[MetamorphosisMonster each transformation]], his intelligence grows, and he uses it to his advantage in his fights - perhaps the best example of this is when he tricks Godzilla into punching his body so that his chemicals can burn his hand down to the bone.

* KnightOfCerebus: Hedorah is a very powerful and particularly gruesome monster, even by the series standards, and he nearly succeeds in killing Godzilla!

* MuckMonster: Hedorah is not an ''animal'' in the same way that the other Kaiju are, instead being a living, breathing chemical plant of an alien made out of Hedrium, an amorphous mineral substance.

* NoAnimalsWereHarmed: Played straight and averted. Averted in that Hedorah's presence in the sea kills millions upon millions of fish and other sea life. Played straight later on, in that right after killing several people playing cards in a nightclub on Mt. Fuji and oozing to the dance scene downstairs, thoroughly terrifying the partiers, Hedorah retreats to fight Godzilla, leaving a small cat covered in sludge but otherwise unharmed.

%% * FreudWasRight: Hedorah's eyes do look like... well, you know.

Rampant pollution off the coast of Japan, combined with a mysterious lifeform that came on a meteorite, has created a monstrous pile of pollution. A researcher, Dr. Yano and his young son Ken are stricken by the creature's poisons upon discovering the creature, who begins making trouble on Japan's coast. The creature is named "Hedorah", after ''hedoro'', the Japanese word for sludge. Ken keeps receiving visions that Godzilla has decided to take the matter in his own hands and is making his way to fight the creature. Though beaten back into the sea on their first encounter, Hedorah quickly adapts and grows in power, choking the streets with his creeping sludge and skeletonizing people where they stand with toxic gases left in his flying wake, and he even brings Godzilla to his knees. With the situation looking dire, a group of teenage hippies plan one final celebration of life on the slopes of Mount Fuji and Dr. Yano manages to find a weakness in Hedorah. Using giant electrodes, the creature can be killed by drying out. Though Hedorah manages to interfere with the power, Godzilla arrives to power them on with his atomic breath and fights harder to make sure Hedorah is KilledOffForReal even resorting to flying in pursuit using his atomic breath.

* MuckMonster: Hedorah is not an ''animal'' in the same way that the other Kaiju are. He's actually a living mineral alien.

->"This movie's a mixture of horror, children's movie, [[TheSeventies '70s]] psychedelic exploitation, and... Godzilla."
-->--'''Creator/JamesRolfe,''' ''WebVideo/CinemassacresMonsterMadness''

* NoPronunciationGuide: The characters in the Titan Productions dub (the 1972 U.S. theatrical release) insist on pronouncing Hedorah as Hee-drah. It gets [[Film/GhidorahTheThreeHeadedMonster confusing]] after a while.

->"''Godzilla vs. The Smog Monster'', also known as ''Godzilla vs. Hedorah'', follows in the line of ''[[Film/AllMonstersAttack Godzilla's Revenge]]'', targeting it towards kids. Little kids. Little kids who get hopped up on sugar to the point that their brains operate on higher levels of existence and their super-sensory nerves subject them to a fantasy world that exceeds that of an adult on the most powerful narcotics known to science! Basically, I'm just trying to say this movie's really weird.... This movie's a mixture of horror, children's movie, [[TheSeventies '70s]] psychedelic exploitation, and... Godzilla."

* PantyShot: Miki, very briefly when she and Yukio tumble out of their car just before it gets swallowed up by Hedorah.

* DeathGlare: Godzilla appears to briefly direct one towards the humans after finally defeating Hedorah at the end of the film. He even appears to gesture towards them, as if to warn them that if they continue with their polluting ways and spawn another Hedorah, he ''will'' turn on them. Considering that one of the characters is shown reacting in fear, it seems the message was received.

* AchillesHeel: Hedorah is extremely strong and ''very'' hard to kill. However, it has a crippling weakness to electricity, which dries it out and kill it.

* GreenAesop: If Godzilla is a metaphor for the danger of nuclear warfare, then Hedorah is one for enviromental damage. He was born of pollution, hurls sludge, and emits poison gas.

On November 3rd, 2021 [[{{Film/GodzillaVsHedorah2021}} a short film of the same name]] saw a rematch between the two monsters using suits from ''Film/GodzillaFinalWars'' for the 67th anniversary of ''Film/{{Gojira}}''.

* [[SapientHouse Sapient Building]]: The factory Hedorah eats in one of the animated sections is not only an actual character, [[https://wikizilla.org/wiki/images/5/57/Smog_Factory_Cast_Ornament.png but according to merchandise manufacturer Cast, who made an ornament out of it]], the factory has a name too! Its name is 'Smog Factory', or ''Kogai Kojo'' in Japanese.

* RealityEnsues: No, a monster that feeds off pollution wouldn't be a good thing, as Dr. Yano clearly states.

* FreudWasRight: Hedorah's eyes do look like... well, you know.

* GettingCrapPastTheRadar: According to Yoshimitsu Banno, Hedorah's eyes are meant to be shaped like vaginas.
