Gamera vs. Gyaos (大怪獣空中戦 ガメラ対ギャオス Daikaijū kūchūsen: Gamera tai Gyaosu, lit. Giant Monster Dogfight: Gamera vs. Gyaos) is a kaiju film made in 1967. It features Gamera and Gyaos.


Express Engineering Corp is building a highway in the forest near Mt. Fuji. Challenged by local villagers, foreman Shiro Tsutsumi and his crew are plagued with protests and sabotage. Nearby, a survey team from the UN is killed when their helicopter is literally cut by a beam emitted from a cave in the mountains. A small boy, Eiichi Kanamura, grandson of the village elder Tatsuemon Kanamura, finds reporter Okabe snooping around. Okabe and Eiichi check out a strange light - which leads them to the cave where Gyaos, a giant bat-like bird-monster, is currently residing.

Running for his life, Okabe ditches Eiichi at the cave - but runs into Gyaos who devours him. Shiro and his crew (who are also checking out the light from the cave) arrive just in time to see an epic battle where Gamera and Gyaos exchange blows (with Eiichi in the middle). During the battle, it is realized that Gyaos can't withstand fire - realizing this Gamera grabs the young boy and gets him to safety. After alerting the public about Gyaos and his abililties, zoologist Dr. Aoki investigate Gyaos's prehistoric origins. The public is put on alert - stay indoors at night - Gyaos is nocturnal. But after another battle with Gamera, Gyaos seems to be the victor (as Gamera tends to his wounds at the bottom of the sea). Even after using light flares to annoy Gyaos, he still annihilates the Japanese Self-Defense Force.

After another battle, Gamera holds Gyaos in the water while the sun rises. But Gyaos, sensing its mortal danger, chooses to sever its own foot in lieu of death and flys off. A plan is put into effect that would draw Gyaos into the sunlight after experiments reveal that the sun causes the severed foot to shrink. The Defense Force constructs a rotating platform with a giant bowl of blood on it. Gyaos, landing on the platform and drinking the blood, will become dizzy and not be able to get off before the sun rises. The plan ultimately fails. It all comes down to a final showdown between Gamera and Gyaos which ends when the sun rises, and Gyaos, weakened, is killed when Gamera throws him into the crater of Mt. Fuji.



  • This is the first movie that Gyaos enters the Gamera Series.
