We commit to the cradle of time the Last Hope, Gamera. May he awaken with the Shadow of Evil, Gyaos.
Gyaos is considered to be Gamera's arch-enemy, and has more film appearances than any of his other enemies. In the Showa series, Gyaos was Gamera's second foe, and emerged from an underground cave to feed on humanity. Gamera battled the creature in several encounters, finally destroying it by pulling it into the crater of an active volcano. However, Gyaos wasn't the only creature of its kind, as multiple silver Space Gyaos were a frequent nuisance on the alien planet Terra in the film Gamera vs. Guiron. The Terrans' guardian monster Guiron fought and brutally killed one Space Gyaos by chopping it apart with its nose blade. In Gamera: Super Monster, Gyaos was one of the monsters controlled by the sinister crew of the pirate spaceship Zanon, which it used to menace humanity and try to defeat Gamera.
In the Heisei trilogy of films, Gyaos was reinvented as a perfect organism genetically engineered by the ancient Atlanteans. Gyaos began reproducing out of control and turned on their creators, who created Gamera as a last-ditch effort to stop them. Gamera succeeded in killing most of the Gyaos, but clutches of their eggs survived into the modern day, where changing environmental conditions brought on by human activity caused them to hatch. Gamera reemerged as well to battle his ancient foe, and successfully killed three Gyaos that appeared in Japan in 1995. However, countless more Gyaos would appear in 1999 as a result of Gamera depleting the Earth's mana in order to destroy Legion. These evolved Hyper Gyaos began overrunning the world, with Gamera desperately trying to defeat them. After Gamera defeated the creature known as Iris, an ancient demonic beast genetically related to Gyaos, a swarm of thousands of Gyaos descended on Japan to attempt to destroy Gamera once and for all.
In the most recent Gamera film, Gamera the Brave, a flock of four Gyaos attacked a Japanese village in 1973, but were attacked by Gamera, who was forced to self-destruct in order to kill them. A new monster called Zedus was eventually spawned by feeding on the corpses of Gyaos, and did battle with the reincarnation of Gamera three decades later.
In Gamera vs. Gyaos, Gyaos' name comes from the onomatopoeia for its roar according to the film's protagonist, Eiichi. Prior to the release of Gamera: Guardian of the Universe, the monster's name was commonly romanized as Gaos, without the "y." The silver spacefaring Gyaos in Gamera vs. Guiron are known as Space Gyaos (宇宙ギャオス. In Uchū Gyaosu)Gamera: Guardian of the Universe, Gyaos are sometimes referred to as Gyaos Birds, although the character Mayumi Nagamine insists they are not birds at all. The singular Gyaos in the film which evolves and grows to 85 meters in height is known as Super Gyaos (スーパーギャオス, while the even larger evolved Gyaos from Sūpā Gyaosu)Gamera 3: Revenge of Iris are called Hyper Gyaos (ギャオス・ハイパー, though neither name is ever spoken onscreen. The Gyaos in Gyaosu Haipā, lit. Gyaos Hyper)Gamera the Brave are called Original Gyaos (オリジナルギャオス according to supplementary materials, though Gyaos' name is never spoken in the film. Orijinaru Gyaosu)
Two suits were created for Gamera vs. Gyaos: one with its wings spread, and another with its wings folded. In addition to the suits, a flying prop and a life-size model of Gyaos' foot were also constructed. The Gyaos costume with the extended wings was later used to portray Space Gyaos in Gamera vs. Guiron, along with a hand-operated puppet or Guignol and a prop. The Space Gyaos suit was later used in the "Godzilla vs. Gamera" stage show at the 1970 World's Fair. Stock footage of Gyaos from its debut film was used for the monster's role in the 1980 film Gamera: Super Monster.

Gyaos was brought back as the antagonist for Gamera's 30th anniversary film, Gamera: Guardian of the Universe. A series of props and puppets was created to portray the three juvenile Gyaos, while two suits were made for the mature Super Gyaos. One suit was designed for action, while the other was for close-ups. Super Gyaos had the distinction of being the first-ever known kaiju to be portrayed by a woman, with director of special effects Shinji Higuchi noting "the shape of a woman's body is different from that of a man's" and "since virtually all of the people who work in the special effects field are men, I thought that I could make it a little easier for women to enter the field by having one play Gyaos." Kameyama was specifically cast due to her small size. In addition to the two suits, a prop was utilized for scenes of Super Gyaos flying.

For Gamera 3: Revenge of Iris, the evolved Hyper Gyaos were depicted entirely through props, puppets, and computer-generated imagery. The Super Gyaos action suit from G1 was reutilized for the Hyper Gyaos that is knocked out of the sky and incinerated by Gamera's Plasma Fireball, with only its head being present. In addition, a full-size juvenile Gyaos carcass model was created for the film's opening sequence.
Like Hyper Gyaos, the Original Gyaos from Gamera the Brave were entirely portrayed through props, puppets, and CGI.

In each of its appearances, Gyaos resembles a giant pterosaur or bat-like creature, with a flattened, arrow shaped head, leathery wings with three claws on each, taloned feet and a tail with a flat sail on top of it.
In Gamera vs. Gyaos, Gyaos' skin is dark brown with orange-red markings across its chest and wings, while its eyes are bright yellow. Gamera vs. Guiron introduced the Space Gyaos, which possesses silver skin with dull reddish-purple markings and amber-colored eyes.
In the Heisei trilogy, Gyaos was given an updated appearance for each film it appeared in. The Gyaos in Gamera: Guardian of the Universe had a more streamlined appearance, with larger wings and a longer neck, along with brownish-red skin. The singular Gyaos which evolves into Super Gyaos develops a slightly more muscular body along with red eyes. In Gamera 3: Revenge of Iris, a new type of Gyaos, Hyper Gyaos, was introduced. While sharing similarities to its earlier forms, Hyper Gyaos has a much more draconic appearance, with larger wings and rough, reddish-brown skin. Hyper Gyaos is also considerably thinner than previous incarnations, with elements of its skeleton such as its ribcage protruding from underneath its skin.
The Original Gyaos in Gamera the Brave are very thin and sleek, with blue skin that is so tight on their bodies that it renders their bones visible underneath. They have pointed snouts and a more decorative pattern on their head crests.
Gyaos are feral, bloodthirsty creatures with no regard for other life whatsoever. In the Showa series, Gyaos feeds on blood, and typically consumes it in large quantities by preying on humans. In the Heisei trilogy, Gyaos feed on any meat they can find, be it living or dead, though their preferred prey seems to be humanity. In the trilogy, Gyaos consumes food in massive amounts, which allows it to grow in size very quickly. Gyaos can quickly wipe out an entire village population due to its ravenous appetite. While Gyaos typically move together in flocks and will cooperate in combat, juvenile Gyaos will resort to cannibalism if left unattended in their nest, eating each other until only the strongest and most vicious individuals are left.
In the Showa series, Gyaos has no definitively explained origin, and is discovered living in a large cave. Zoologist Dr. Aoki evades the question of whether he is a bird or a reptile, though he labels his drawing of Gyaos "Rhamphorhynchoidea Monster." In Gamera vs. Guiron, it is revealed that there are multiple silver space-faring Gyaos, suggesting that Gyaos may be an extraterrestrial species, or that there are multiple species of Gyaos specific to other planets.
In the Heisei trilogy, Gyaos are the result of genetic engineering by the ancient Atlanteans in order to create a genetically perfect organism, possibly as a weapon. However, the asexually-reproducing Gyaos began breeding out of control and turned on their creators. The Atlanteans created Gamera as a last-ditch effort to stop the Gyaos, but their civilization was ultimately destroyed by the Gyaos. While Gamera successfully destroyed most of the Gyaos, several clutches of their eggs survived into the present day and were able to hatch due to human activities causing a decrease in the Earth's levels of Mana. The characters Mito Asakura and Shinya Kurata propose in Gamera 3: Revenge of Iris that Gyaos was created to keep the human population from growing too large. The official prequel graphic novel for the trilogy, Matt Frank's The Last Hope, explains that the Atlanteans created Gyaos to defend their capital city from gigantic serpents called Garasharp. However, once the Gyaos defeated and fed on Garasharp, they developed a taste for human flesh instead, and turned against the Atlanteans.
Gyaos appeared in Japan from a large cavern, and feasted on blood, principally that of livestock and humans. Soon, Gamera confronted Gyaos, and after a battle Gyaos fled while Gamera slept in the ocean to recover. It was soon learned that light caused Gyaos' skin to shrink, so the light of the city stadium of Nagoya kept Gyaos at bay. Gamera soon returned to finish Gyaos off and, after a battle in the air, Gyaos cut off its own foot to escape from the sun.
Humanity developed a plan to place artificial blood on a rooftop in Nagoya to keep Gyaos drinking the blood for so long that the sun would come up and kill it. But Gyaos proved more cunning than originally thought and used a strange fog attack to protect itself from the sun. The next plan was to lure Gamera to Gyaos' lair in the forest by setting the forest alight. Gyaos used its fog attack to put out the flames, but Gamera arrived and eventually defeated Gyaos by throwing the beast into a volcano.
A swarm of silver Space Gyaos (宇宙ギャオス had attacked the planet Uchū Gyaosu)Terra, an undiscovered planet in our solar system, being kept at bay only by the Terrans' guardian monster, Guiron. A Space Gyaos arrived near Guiron and tried to attack with its laser beam, but it was reflected by Guiron's bladed face, and instead sliced off Space Gyaos' right leg. Gyaos flew into the air in order to continue the fight, but in a swooping maneuver Guiron sliced off Space Gyaos' wing. With its prey grounded and immobile, Guiron cut off Gyaos' other wing before decapitating it and slicing its body into disc-like chunks before deciding that Space Gyaos was not fit to eat. After Gamera had killed Guiron, the planet was seemingly abandoned to the Gyaos.
The pirate spaceship Zanon unleashed Gyaos to destroy humanity, then sent it to prevent Gamera from interfering with its plans to conquer the Earth. However, Gamera destroyed Gyaos by dragging it into the crater of a volcano.
Three Gyaos appeared on an island archipelago on the coast of Japan, where they wiped out an entire village on Himegami Island, eating every human being they could find. Ornithologist Mayumi Nagamine and police inspector Tsutomu Osako were sent to the island to investigate, where they saw the three creatures up close. Together with the JSDF, Nagamine and Osako formulated a plan to lure the Gyaos to the Fukuoka Dome in Fukuoka, using hunks of raw meat. By nightfall, the three Gyaos arrived at the stadium and descended. Soldiers then opened fire on the Gyaos with tranquilizer darts. Two of the Gyaos were sedated and captured, but one escaped. The Gyaos tried to fly over the ocean, but was suddenly swatted into a nearby refinery and destroyed by Gamera, who proceeded toward the Fukuoka Dome. The two Gyaos awakened and used their sonic beams to cut free of the cages restraining them. The Gyaos flew out of the stadium, avoiding Gamera, and retreated.
The two Gyaos later attacked a village in the Japanese countryside, but were intercepted by Gamera. Gamera destroyed one of the Gyaos with a fireball, but the other escaped. When Gamera was attacked by the JSDF near Mount Fuji, the surviving Gyaos attacked him with its supersonic scalpel. Gamera was seriously wounded by the JSDF and Gyaos' attacks and was forced to rest underneath the ocean. Gyaos began feeding on wildlife, livestock, and humans and eventually grew into the 85 meter-tall Super Gyaos (スーパーギャオス. Super Gyaos flew to Sūpā Gyaosu)Tokyo, where it fed on the helpless populace. Super Gyaos later built a nest on the Tokyo Tower and laid eggs. Gamera traveled underground and surfaced in the center of Tokyo to challenge Super Gyaos. Gamera blasted the nest with a fireball, destroying all of the eggs. Super Gyaos and Gamera fought throughout Tokyo, causing major damage to the city. Eventually, the two kaiju took their battle to the sky, engaging in a supersonic dogfight that reached the top of the atmosphere. Gamera and Super Gyaos plummeted down to Earth, and Gamera crashed into a factory which exploded. Super Gyaos stared at the fireball, believing itself victorious, when suddenly the fire was absorbed by Gamera, who stood unharmed. Gamera fired a massive fireball at Super Gyaos, which blasted its head clean off. Super Gyaos' headless corpse then fell backwards and exploded.
The Gyaos do not appear in Gamera 2 physically, but they are mentioned and are the subject of a book in the film.
After Gamera's Ultimate Mana Blast attack used to destroy Legion depleted the Earth's Mana, thousands of Gyaos began appearing all over the world in new evolved forms known as Hyper Gyaos (ギャオス・ハイパー. The corpse of one Gyaos was found in a village in the Gyaosu ・ Haipā, lit. Gyaos Hyper)Philippines, where it had eaten an old woman's son and grandson. Gamera was reportedly seen in several locations across the planet battling the Hyper Gyaos, causing terrible destruction in the process. One night, two Hyper Gyaos appeared in the Shibuya district of Tokyo, where they battled Gamera. Gamera killed both Gyaos, but at the cost of thousands of human lives, ending humanity's trust in Gamera and causing them to designate him as an enemy. Meanwhile, a powerful creature related to the Gyaos, Iris, was awakened from a shrine in Nara Prefecture and raised by the vengeful orphan Ayana Hirasaka to kill Gamera, who she blamed for the deaths of her parents in 1995. Iris and Gamera battled in Kyoto, with Iris being killed and Gamera brutally maimed. After the battle, a swarm of thousands of Hyper Gyaos approached Kyoto, intent on finishing Gamera once and for all. However, humanity's faith in Gamera had been restored and they were ready to fight side-by-side with him against the Gyaos.
A flock of Original Gyaos (オリジナルギャオス attacked the small village of Iseshima, only to be confronted by Orijinaru Gyaosu)Avant Gamera. Gamera overloaded his internal furnace and self-destructed, sacrificing himself to destroy the flock. The creature called Zedus was later mutated by feeding on the corpses of Gyaos.
Gyaos appears in the 2015 short first screened at New York Comic-Con to commemorate Gamera's 50th anniversary. Swarms of Gyaos are shown attacking Tokyo ten years in the past, and one of them eats the main character's father. The main character is saved when Gamera smashes through a building and kills the Gyaos by stomping on its neck. Gamera then destroys the incoming swarm of Gyaos with a powerful blast of fire.
In all of its incarnations, Gyaos is an agile flier. It can fly at a speed of Mach 3.5 in the Showa series, while the juvenile Gyaos from Gamera: Guardian of the Universe can reach speeds of up to Mach 1. Super Gyaos can reach Mach 4.2, while Hyper Gyaos can reach Mach 4.5. Their impressive flight speed and agility allowed Super and Hyper Gyaos to dodge the majority of the Plasma Fireballs Gamera fired at them.
Gyaos can generate powerful wind gusts which blow away buildings and tanks by flapping its wings.
Gyaos' signature ability is the Supersonic Scalpel (超音波メス it fires from its mouth. This attack takes the form of a thin yellow beam which can slice apart objects with incredible precision. In the Showa series, Gyaos' spine was bifurcated at the neck, acting as a tuning fork that allowed it to fire the Supersonic Scalpel at the cost of not being able to turn its head. This does not apply to the Heisei versions of Gyaos, which can move their heads and necks freely. The Supersonic Scalpel can slice cleanly through aircraft and buildings as well as Gamera's flesh, and is even used by Gyaos twice to sever its own foot in order to escape Gamera's grasp. The mutant Gyaos Chōonpa Mesu)Iris possesses its own version of the Supersonic Scalpel which it fires from its tentacles.
The Showa Gyaos has a powerful healing factor, which renders it capable of regrowing its severed foot after only an hour.
In Gamera vs. Gyaos, Gyaos could emit a fog-like gas from vents on its chest to obscure the sun and douse flames.
In the Heisei series, Gyaos attacks with its hind claws. While this is never addressed onscreen, the Heisei Gyaos emits a neurotoxin through its claws.
In the Heisei trilogy, Gyaos are born female but can manipulate their own chromosomes to reproduce asexually. This allows Gyaos to reproduce very quickly and overrun both ancient Atlantis and the modern world by the events of Gamera 3: Revenge of Iris.
In the Heisei trilogy, Gyaos are born with a single pair of perfect chromosomes which they can alter in order to evolve in response to stimuli. Not only does this allow Gyaos to reproduce asexually, but also to develop adaptations, such as shield plates over its eyes in order to protect it from sunlight and allow it to be active during the day.
The Heisei Gyaos can grow and evolve quickly as long as it continues to eat. By eating continuously, one Gyaos grew from a 10 meter juvenile to the 85 meter-tall Super Gyaos.
Super Gyaos is able to shrug off missiles and can survive orbital re-entry.
Gyaos possesses an aversion to sunlight, and as such can only be active at night. In the Showa series this weakness extended to the point that exposure to sunlight could injure Gyaos by causing its flesh to dry out and shrivel up. In the Heisei series, Gyaos was blinded by sunlight and was rendered helpless and disoriented if exposed to any light. However, Super Gyaos was able to overcome this weakness by forming shield plates over its eyes.
Gyaos is critically weak to extreme heat, which is how Gamera manages to kill it in each incarnation. In Gamera vs. Gyaos, Gamera kills Gyaos by dragging it into the mouth of an active volcano, while in the Heisei series he kills each Gyaos with a Plasma Fireball. While the juvenile Gyaos can be exterminated by a single Fireball, Super Gyaos required a direct hit to the head from a High Plasma Fireball while Hyper Gyaos could withstand several hits.
In the Showa series, the source of Gyaos' Supersonic Scalpel beam is its forked-shaped throat, but this prevents it from turning its head sideways. Space Gyaos was also vulnerable to its own Supersonic Scalpel after it was reflected by Guiron. Space Gyaos is susceptible to being instantly and fatally dismembered by the blade on Guiron's head.
Space Gyaos is beheaded by Guiron.

Gyaos is featured in the survival RPG City Shrouded in Shadow developed by Granzella and Bandai Namco for the PlayStation 4. Flocks of Gyaos fly around the city and antagonize the player and other NPCs. On the second part of the game's tenth stage, Gamera appears to battle the Gyaos.

Gyaos appears in this 1995 manga illustrated by Hurricane Ryu Hariken, along with several other kaiju. Eventually, Gyaos merges with all of Gamera's other foes from the Showa era into a chimera-like creature called Powered Gyaos, which is defeated by Gamera.
After the battle between Gamera and Super Gyaos, Dr. Greta Karbone illegally obtained a sample of Gyaos' DNA. On her private island in Guanajota Mexico, she and her assistants Gusano and Carlos worked to create an army of Supermonsters, which included a cloned Gyaos. However, Gyaos quickly grew too big for its incubation jar and escaped. It ate Carlos before flying through the roof and escaping into Guanajota Harbor. Gyaos lived for some time on whatever humans it could find, such as lone fishermen, before entering Guanajota. As soon as it landed it began to wreak havoc. It had destroyed many structures, and the city was aflame before Gamera arrived. Gamera hit Gyaos with a fire blast from behind. On turning to see its aggressor, Gyaos returned fire. Gyaos then leaped upon Gamera, who used one of his tusks to stab Gyaos' ankle. Not swayed by the attack, the two monsters prepared their next attacks as the people fled the ruined city.
Gyaos charged at Gamera with a headbutt, but Gamera grabbed Gyaos' shoulders and lead it into a roll that Gamera used to slam Gyaos into the water. Gyaos managed to get back up, but it then saw Gamera blasting through the air toward it. Gamera tackled Gyaos so that it fell backwards into a tanker ship in the harbor, and then blasted upward and spat his fire blast at Gyaos, igniting the oil in the tanker and bringing the entire Guanajota harbor to a boil. Gamera sustained the blast on the harbor, and the helpless Gyaos clone was effectively obliterated.
Gamera was being attacked by four Gyaos' Supersonic Scalpels. Gamera killed a first Gyaos with a point-blank fire blast and then stomped on its head. The remaining three Gyaos kept firing at Gamera, but Gamera got into his shell and charged up a fire blast which he fired at one of the Gyaos. Another Gyaos came in and bit Gamera's arm, and Gamera threw it to the ground and fired at it, killing it. The two remaining Gyaos hovered about, and Gamera fired another fire blast at one of them. From the smoke one Gyaos flew toward Gamera and unleashed a flurry of beams. Gamera punched it to the ground. However, the Gyaos continued its onslaught of beams just as the other Gyaos turned out to have survived and flew over to Gamera. Gamera began spurting blood, and the two Gyaos feasted on his entrails. Gamera, acknowledging he had been defeated, triggered his Fireball Ejection Suicide, killing him along with both Gyaos.
