This page is a list of minor monsters from Toho-licensed media. This is defined as any kaiju, kaijin, animals, or other beings whose roles generally have little overall relevance in the media they are featured in, and which are generally not trademarked. As a result, this page doesn't include characters such as Meganulon or Meganula, Fairy Mothra, Garu Garu, Barem, and Ghogo, who are all trademarked.

Godzilla series

(三葉虫,   San'yōchū)

(トリロバイト,   Torirobaito)

Godzilla (1954)
Main article: Trilobite.
In Godzilla, a living trilobite was discovered by Dr. Kyohei Yamane in one of Godzilla's footprints on Odo Island. Yamane concluded from the creature's presence in the footprint along with the age of the sediment found with it that Godzilla must have been living in a deep underwater pocket since the Jurassic before being disturbed by H-bomb testing. In Godzilla Against Mechagodzilla, Dr. Tokumitsu Yuhara created a cybernetic "Mecha-Trilobite." This technology would lay the groundwork for the construction of Kiryu using the original Godzilla's skeleton.
Giant Lizard

King Kong vs. Godzilla (1962)
Main article: Giant Lizard.
The Giant Lizard scared Kinsaburo Furue while he and an exploration party searched the jungles of Farou Island for King Kong. Osamu Sakurai informed Furue that it was only a lizard and instructed him to throw it, then shot and killed the creature with his rifle.
Giant Octopus
(大ダコ,   Ōdako)
King Kong vs. Godzilla (1962)
Frankenstein vs. Baragon (1965) [alternate ending]
The War of the Gargantuas (1966)

In King Kong vs. Godzilla, the Giant Octopus attacked a village on Farou Island before being driven off by King Kong. The Giant Octopus was also featured in the unused alternate ending for Frankenstein vs. Baragon, where it appeared from the depths and dragged Frankenstein underwater after his victory over Baragon. The Giant Octopus' last film appearance came the following year in The War of the Gargantuas, where it attacked a boat and fought Gaira at sea.

Giant Praying Mantis
(大カマキリ,   Ōkamakiri)
Son of Godzilla (1967)
Height: ~2 meters[1]

The Giant Praying Mantises were native to Solgell Island, and stalked its jungles at night. One mantis wandered too close to the camp of several United Nations scientists on the island, who were able to scare it away with gunshots. When the scientists' weather-controlling experiment went awry and triggered unrelenting radioactive storms, three of these mantises were mutated into giant monsters dubbed Kamacuras.

Hitokui Shokubutsu
AMA - Maneater grabs Ichiro.jpg
All Monsters Attack (1969)
Height: Unknown[2][3]Weight: Unknown[2][3]Place of Emergence: Dream Monster Island[2]

The Maneater appeared when Ichiro Miki walked in front of it, distracted by watching Minilla trying to fire atomic breath in front of Godzilla but failing. The Maneater sneakily grabbed Ichiro, put him up to its body, and covered his mouth so he couldn't talk. Ichiro then woke up from his dream and realized that he was being kidnapped by robbers.

  • The Maneater's Japanese name, Hitokui Shokubutsu, literally translates to "man-eating plant," referencing how it grabbed Ichiro Miki and tried to eat him. A 2008 Cast ornament of the creature gives it the full name Man-Eating Plant of Dream Monster Island (夢の怪獣島の人食い植物,   Yume no Kaijū-tō no Hitokui Shokubutsu).

Smog Factory
Kōgai Kōjō
Godzilla vs. Hedorah (1971)

During one of the film's animated segments, the Smog Factory made an appearance, grabbing up surrounding trees with its claws and growing in size while producing large quantities of smog. Hedorah appeared and ate the smog being produced, sitting on top of the factory and consuming it whole. Once the Smog Factory was completely consumed, Hedorah flew away.

  • An ornament of Smog Factory along with an animated Hedorah has been produced by Cast.

Main article: Dorat.
Genetically engineered pets from the future, three Dorats were released on Lagos Island in 1944 by the Futurian Emmy Kano. In 1954, the Dorats were exposed to the Castle Bravo H-bomb test, which merged them together and mutated them into King Ghidorah.
(シプニオキス,   Shipuniokisu)
Godzilla vs. Mechagodzilla II (1993)

Shipniocus is a prehistoric fernaceous plant discovered adhering to the eggs of both BabyGodzilla and Rodan on Adonoa Island. It emits a mysterious telepathic energy which when interpreted by psychics and fed into a recording produces a melody. Whenever Baby or Rodan heard this melody, they received a large intake of power. In the case of Rodan, the energy from this melody was sufficient to revive him following his battle with Godzilla and transform him into Fire Rodan.

Pteranodon Robot
(翼竜ロボット,   Yokuryū Robotto,
lit. Pterosaur Robot)


GVMGII - Pteranodon Robot full.png
Godzilla vs. Mechagodzilla II (1993)

The brainchild of Kazuma Aoki, the Pteranodon Robot was a flying vehicle modeled after the Pteranodons he adored so much. Aoki brought the completed robot to the enclosure where BabyGodzilla was being held by the United Nations Godzilla Countermeasures Center and cared for by Azusa Gojo. Aoki let Azusa ride on the robot with him, but as they passed over Baby's enclosure the robot sputtered and suddenly dropped out of the sky, crashing in the enclosure. Both Aoki and Azusa were unhurt, though the Pteranodon Robot was damaged. Aoki later repaired the Pteranodon Robot and used it to exit the Garuda during the battle between Godzilla and Super Mechagodzilla.

  • In addition to a prop of the monster's entire body, special effects director Teruyoshi Nakano also constructed a large animatronic of the Dragon's neck.
  • A popular rumor is that the Dragon prop was originally constructed for the unmade Toho and Hammer collaboration film Nessie, and reused by Teruyoshi Nakano for Princess from the Moon. However, given that Nessie was cancelled nearly a decade before Princess from the Moon was produced, and that no confirmation of this is made in any known official books, this rumor is likely false.

(アンキロサウルス,   Ankirosaurusu)
1992-3 Kodansha Manga - Anguirus as Ankylosaurus.JPG
Godzilla, King of the Monsters

A new species of Ankylosaurus discovered by Doctor Oniyama with the assistance of a version of himself who travelled through time, Ankylosaurus's fossilised skeleton was placed on display at a Dinosaur Expo. With the Expo in operation, the two Oniyamas used KIDS to fire a beam into the fossil to revive it, resulting in a living Ankylosaurus. Aware that Godzilla would come to protect Miki Hideo and his friends, who were at the Expo, the Oniyamas used KIDS to devolve Godzilla into Godzillasaurus, and the two ancient reptiles fought. With Ankylosaurus losing the fight, KIDS was used again to fire a syringe full of DNA into Ankylosaurus's body, causing it to rapidly grow into a full-size Anguirus.

  • The Ankylosaurus' roar is rendered as "Gyaaasu" (ギャアアス).
  • According to Doctor Oniyama, Ankylosaurus's species was a natural rival to that of Godzillasaurus.
