One of many monsters spawned when the electronic brain controlling planet Terra went haywire and altered the environment, Guiron fell under the control of the last two surviving Terrans, Barbella and Florbella, who used him as their guardian monster. Guiron was kept underneath a riverbed on Terra and summoned whenever Space Gyaos menaced the planet. When Gamera arrived to save two children who were kidnapped by the Terrans, Guiron was unleashed to battle him. Guiron triumphed in their first encounter, but Gamera recovered and sprung back into action, ultimately killing Guiron by throwing a missile into his head and igniting it.
Name[edit | edit source]
Guiron's Japanese name Giron (ギロン) is most likely a truncation of the Japanese word for guillotine, girochin (ギロチン), a clear reference to the monster's sharp, blade-like head. In English, the monster's official name is "Guiron," but the spellings "Guilon" and "Guillon" have been used in official merchandise as well.
In earlier scripts for Gamera vs. Guiron, Guiron was simply called Giant Evil Beast X (大悪獣Ｘ. Dai Aku-jū Ekkusu)
Development[edit | edit source]
Guiron was designed by Tomohisa Yano on behalf of Akira Inoue, who suffered a backache while working on preparations for the 1970 World's Fair before work began on Gamera vs. Guiron. According to director Noriaki Yuasa, Yano initially wanted the new monster to be a flounder-like monster with the actor entering its suit sideways, but this was too difficult to realize. Inoue commented that the design of the enemy monster was "biologically in mind" at first, and of the final design of Guiron - which was far from "biological" and contrary to this idea - said "I created an amazing monster anyway. The staff came up with the idea of having the whole body be a weapon, and when I put the head of a knife on a body I created Guiron. It's not a living thing anymore, the idea comes from a weapon. Only Guiron is like this." Looking back on the series, Inoue cited Gamera vs. Guiron as his favorite work.
While Ex Productions was typically in charge of modeling monsters for the Gamera series, the company was busy modeling Yongary for the South Korean monster film Yongary, Monster from the Deep. Instead, Eizo Kaimai's Kaimai Productions handled modeling of the Guiron suit. An elaborate miniature model of Guiron was also created.
Guiron was revisited as a possible foe for Gamera in the second entry of the Heisei trilogy, but did not make the cut. However, many features of Guiron such as his extraterrestrial origin, facial horn used as a weapon, and a body made of inorganic material were present in the Mother Legion. Director Shusuke Kaneko stated that he was in charge of writing the script and coming up with ideas for Gamera 2 with Shinji Higuchi and said that Guiron was indeed considered as an enemy monster. Writer Kazunori Ito stressed, however, that Guiron did not form the basis for the Mother Legion, who was conceived based on ideas for the story. Ito did however state that Legion being a space monster may have been influenced by Guiron.
Design[edit | edit source]
Guiron is an alien monster that normally walks on all fours, but can also stand on two legs when the situation requires. It is an unusual-looking creature, with tough gray skin, a small mouth, sleepy looking eyes and a low, groaning bellow. The most unusual feature of this beast's anatomy, however, is the gigantic blade that it sports on its head, which is nearly as long as its body.
History[edit | edit source]
- Gamera vs. Guiron (1969)
- Gamera vs. Jiger (1970) [stock footage]
- Gamera Super Monster (1980) [stock footage]
Guiron acted as the guardian monster of two brain-eating space women, the last of a dead civilization on the planet Terra, and lived in a special hangar under a stream at the Terran Base. The aliens guided him with a mind control device. Before the Terrans revealed their true intentions, Guiron proved his combat prowess by effortlessly killing a Space Gyaos, reflecting its sonic cutter beam and literally slicing it to pieces with his blade. Guiron later fought Gamera, and nearly killed him as well, before returning to base. After the two kids activated the doors to Guiron's home, he once again came back from below ground, and destroyed the Terran Base. The fire given off by the burning buildings revived Gamera, who challenged Guiron to continue the fight. After a long fight in which Gamera used new acrobatic techniques to try and outsmart Guiron, Gamera eventually managed to defeat the knife headed beast by flipping him upside down - his blade stuck in the earth - then igniting a missile that had gotten stuck in his circular indents, blowing off the upper half of his body, Shortly after his bisected body landed on the ground, Guiron died, bringing an end to Terra's strongest monster.
Abilities[edit | edit source]
Blade[edit | edit source]
Guiron is mostly a melee-oriented kaiju. Almost all of his abilities revolve around the massive blade he sports on his forehead. It is 100 times harder than diamond, strong enough to reflect Space Gyaos' Supersonic Scalpel and cut into Gamera's shell after repeated stabs.

Shurikens[edit | edit source]
Due to Guiron's blade only being usable as a weapon at close range, Guiron will resort to his secondary attack, a pair of four shurikens stored in two circular indents in the side of his head, located just behind the cutting edge of his blade. These shurikens are incredibly sharp and also induce severe bleeding in any opponent they hit, enough to render Gamera unconscious in mere minutes. Guiron can guide these shurikens using telepathic waves. They were sharp enough to cut right through Gamera's arms and lacerate his temples to the point of unconsciousness.
Physical abilities[edit | edit source]
Despite his bulky appearance, Guiron can be extremely agile in battle, as noticed when he was able to leap high into the air to take down Space Gyaos. Guiron displays an impressive amount of strength and persistence in battle, demonstrated when he was able to cut through Gamera's shell by repeatedly slamming his blade down on it. Guiron can jump up to a distance of 1,300 meters per jump. Guiron's eyes have a 360 degree field of view like a chameleon's, and his teeth are 60 times sharper than those of a piranha. Guiron has powerful magnetic suction cups in the palms of his hands which can attract objects.
Weaknesses[edit | edit source]
The skin over the part of Guiron's head where he launches his shurikens is weak, which Gamera exploits by shoving a missile through it and then detonating it, killing Guiron.

Roar[edit | edit source]
Guiron emits slowed-down lion roars. After Guiron kills the Space Gyaos by beheading it, he can also be heard making a low, guttural laugh. The cries of disgust Guiron makes when he inspects slices of Space Gyaos' carcass are actually director Noriaki Yuasa saying "Kusee, kusee," as written by the recording staff. These roars would later be used for the monster Scoradon from the show Fireman.
Trivia[edit | edit source]
- Guiron is referenced in Gamera the Brave. When Toto is exploring the house, Toru's father accidentally knocks a knife off a counter while he is cooking. The knife sticks into the floor, and Toto breathes fire at the blade.
- It has been popularly speculated that Knifehead, a kaiju from Pacific Rim, was possibly inspired by Guiron, also possessing a blade-tipped head. However, in a two-part interview with Ain't It Cool News, Pacific Rim director Guillermo Del Toro revealed that Knifehead was not inspired by Guiron. According to Del Toro, Wayne Barlowe, who drew a silhouette that became Knifehead in the final film, had never heard of Guiron when he drew the silhouette. Del Toro acknowledged in the interview the resemblance between the two kaiju, though he further noted that upon comparison the two kaiju "don't look alike."
- Guiron's head makes a brief appearance in Pacific Rim Uprising, during the scene where Hermann Gottlieb examines PPDC records in search of a match for the image Mako Mori transmitted.
- While Guiron is initially shown to have been decapitated after the missile lodged in his head explodes, he is shown seconds later dying with his head still intact, having been bisected by the explosion instead.
- Many pieces of concept art for Guiron depict him as bipedal.
- Within an anatomical illustration, Guiron was noted to have poisonous liquid within its body.
