Kamoebas (カメーバ,   Kamēba?) is a giant mutated turtle kaiju created by Toho that first appeared in the 1970 Toho film, Space Amoeba.


Kamoebas' name is derived from the Japanese word "kame" (カメ?), which means "turtle," and "amoeba,"a reference to Kamoebas' creator, the giant space amoeba Yog.

Kamoebas' scientific name given in Godzilla: Tokyo S.O.S., "Megalo matamata," is likely derived from the Greek word "Megalos," which means "giant" or "great," and "matamata," which comes from the mata mata turtle.


Kamoebas was a mata mata turtle living on Sergio Island that was possessed and mutated into a monster by the alien amoeba Yog in his attempt to conquer the Earth. Although Kamoebas was killed along with Yog and Ganimes, at least one other Kamoebas existed on the island and was first sighted in 1987.

In Godzilla: Rulers of Earth, Kamoebas is an ancient creature that has existed since prehistoric times, and like most of the other kaiju in the comic is part of the natural balance of the Earth.


Showa Series

Space Amoeba

After Ganimes was destroyed, Yog turned to a mata mata turtle transformed it into Kamoebas, while also creating another Ganimes. However, bats fled from a nearby cave and caused Yog to lose control of the monsters. Kamoebas and Ganimes battled each other up the mountain in the center of the island and both fell into the volcano, destroying themselves and Yog forever.

Go! Godman

Kamoebas suddenly appeared at a beach and terrorized some beach-goers. The couple called out for Godman, who heard their plea and appeared on the scene in a matter of seconds. Kamoebas was confronted by the hero, and attempted to defend itself any way it could; mostly scratching and biting while rising on its hind legs. Despite making a valiant effort, Kamoebas was eventually outmatched and quickly destroyed by Godman.

Millennium Series

Godzilla: Tokyo S.O.S.

A dead Kamoebas, the first specimen of its kind seen since 1987, washed ashore in Japan in 2004, with gaping slash wounds in its neck. The J.X.S.D.F. surrounded the carcass and examined it, determining that it was probably attacked by a huge predator, most likely Godzilla, and eventually died from its wounds.


  • Kamoebas has a hard carapace.
  • Kamoebas has an extendable neck.

Godzilla: Rulers of Earth

Kamoebas was first seen in a flashback where it came to shore while Gorosaurus and Megaguirus fought. It was classified as a "water kaiju" by the Shobijin. Kamoebas was captured by the Trilopods at some point and was imprisoned in their hive. King Caesar recognized Kamoebas as a monster from his time and freed him before freeing all of the other imprisoned kaiju. Kamoebas then assisted in the final battle against the Trilopods and Magita, and followed Godzilla out to sea along with the other monsters once the battle was over.

In Go! Godman, Kamoebas reused Mukadender's roars.

In Other Languages

  • Russian: Камоэбас
  • Yiddish: קאַמאָעבאַס


  • In the movie Godzilla: Tokyo S.O.S., Anguirus was supposed to be the monster whose carcass washes ashore, not Kamoebas. However, staff thought that putting Anguirus in that role would draw negative fan reactions, so they changed the monster to Kamoebas. Another, unconfirmed reason may be because Anguirus is traditionally Godzilla's ally. It is also sometimes believed that Kamoebas was included as an indirect shot at fellow turtle kaiju Gamera, although once again, this is purely rumor.
    • Concept art shows that Kamoebas' role also originally was meant for a Liopleurodon, but Toho felt it would be odd to introduce a brand new creature just to have it die in an unseen fight.
  • Godzilla: Tokyo S.O.S. establishes that a Kamoebas was sighted in 1987, even though the Kamoebas seen in Space Amoeba died along with Ganimes and Yog in 1970. It is possible that, like he had done with Ganimes, Yog possessed more than one mata mata turtle on the island and created multiple Kamoebas specimens.
  • The Giant Turtle from the Godzilla: The Series episode End of the Line shares some traits with Kamoebas, most prominently its spiky shell and extendable neck.

Kamoebas has to be one of my favourite minor monsters in the franchise. He's got a pretty cool design in general.

It's hilarious how Kamoebas got a new design for Millennium series yet only made an appearance as a dead corpse that washed up on a beach.

Poor Kamoebas. He doesn't get a lot of love.
