A Short, Incomplete History of Kaiju

(OOC Note: This will not include every possible Kaiju story, only ones that I am especially familiar with.  I shudder to think of even trying to include all forty-odd years of Ultraman series in here, as well as all the various tokusatsu that were essentially Ultraman knock-offs.   Since many of these stories contradict one another, I will  be "adapting" continuity somewhat arbitrarily to suit myself, and what I think makes for a better story.)


Kaiju” is a Japanese word usually translated as “giant monster”, but which would be better rendered as “strange creature’. It is typically applied to a wide range of creatures, including but not limited to:


  1. Otherwise normal animals of unusually large size.
  2. Animals and plant life mutated by exposure to radiation or chemical or other agents.
  3. Life forms engineered (by both terrestrial and extraterrestrial civilizations) to serve as living weapons.
  4. Extraterrestrial beings.
  5. Various as yet unclassified creatures.

The term kaiju was used primarily in Japan for many years before it became known in other parts of the world. There have been objections to the word as "unscientific", but it did enjoy a brief vogue outside Japan in the early Twenty-First Century. Whether the newer term "Titans", which has come into vogue recently. will supplant it remains to be seen. Note that kaiju are distinguished from "mecha", giant robots which are often used as weapons systems, and which often share many characteristics with them.


What little we know about this period in Earth's history comes from scant archaeological evidence and the occasional testimony of the beings known variously as the "Cosmos", the "Elias" and the "Shobijin".

65,000,000 BC:  King Ghidorah visits Earth, wiping out the dinosaurs.  It battles a time-traveling Mothra V from the year 1998.(1)


60,000,000 BC:  The spacecraft containing Orgah crashlands on Earth. (2 )


10,000,000 BC: Death Ghidorah attacks Earth, but is sealed away by a race of moth-like creatures and their humanoid allies, the Elias. (3)


10,000 BC:  Mothra battles Gigan on Infant Island. (4)

The First "Monsters"

AD 1933:   Promoter Carl Denham brings the giant ape named “King Kong” from Skull Island to New York City, where Kong escapes and is destroyed by military airplanes   A subsequent expedition to Skull Island discovers a juvenile giant ape they name “Son of Kong”.  This ape perishes in a volcanic eruption, and the island is believed destroyed. (5)  Sometime later, Denham adopts the alias “Max O’Hara”, and, returning to the U.S., and establishes himself as a theatrical agent.(6)


AD 1944:  Events this year include:

  • Two  fighter pilots, American Hank Marlow and Japanese Gunpei Ikari, parachute onto a South Pacific island after a dogfight and engage in close combat, but the fight is interrupted by a giant ape. In fact, they had  landed on Skull Island. (7)
  • Japanese soldiers stationed on Lagos Island encounter the dinosaur (later designated "godzillasaurus") that will one day become Godzilla VI. It inadvertently saves them by destroying American landing forces.  Wilson's team of time travelers (See 1992) teleports the godzillasaurus into the North Pacific, and surreptitiously leaves three genetically engineered creates called "Dorats" on the island instead. The island is subsequently used for a nuclear test, and the three Dorats fuse and mutate into King Ghidorah II, which then goes into hibernation.(8)


AD 1945: The beating, undying heart of Frankenstein’s Monster is taken out of Germany by U-boat and delivered to a Japanese submarine in the Indian Ocean. It is then taken to Hiroshima, where it is presumed destroyed in the atomic blast. (9)

  • Gamera returns to Earth, where it battles the monster Barugon. (29)

AD 1967: Events this year include:

  • A U.N. weather control experiment in the South Pacific accidentally causes a spider and several praying mantises to mutate and become the monsters Kumonga and Kamacurus, as well as reviving an immature Godzilla-type creature that they call “Minilla”. When Kumonga and Kamacurus attack Minilla, Godzilla II responds to its distress and drives them off. The weather experiment goes further awry and freezes the island, putting Godzilla II and Minilla into hibernation. (30)

(36)  Several kaiju – including Gamera, the Gappas, the Kongs, and others – evaded capture.  Mothra III’s compliance was obtained through the mediation of the Shobijin.

AD 1968:  Events this year include:

  • Gamera defeats the alien monster Viras.  (37)
  • Aliens called the Kilaaks attempt to conquer the Earth using King Ghidorah as well as the mind-controlled monsters from Monsterland. The Kilaaks are defeated through the combined efforts of humanity and Earth’s monsters. (36) During the Kilaak invasion, Tokyo, Beijing, Moscow, London, Paris and New York City are largely destroyed.  The resultant political dislocation causes a seismic shift in relations between the nations of Earth.  While there will still be conflicts between nations, humans will be increasingly less concerned with fighting among themselves than with potential alien threats.
  • Japan moves its capital to Osaka. UN HQ is moved to Geneva.While Tokyo will be rebuilt, it will never be quite what it was. A movement begins in Japan to move out of cities. Going forward, cities in Japan will be built with kaiju attacks in mind.

(4)  Upon examination, M-mutants are all found to have a chemical compound in their  systems called M-base.They are later found to be the result of genetic manipulation by the Xiliens.
  • The alien Followers of Light recruit three humans, Richard Carson,  Genji Odashu and Ilongo  Savage, to battle their ancient enemy, Lord Maur-Kon. For the next two years, the trio pilot the mechas known as Raydeen, Combatra and Dangard Ace before finally defeating Maur-Kon with the help of the Fantastic Four. (54)

Wilson uses King Ghidorah II to attack Japan.  Godzilla VI is further mutated when it absorbs energy from a Japanese nuclear submarine. It battles and badly mauls King Ghidorah II.  Emi Kano brings Mecha-King Ghidorah back from the future.  It subdues Godzilla VI but is destroyed in the process. (8) She then returns to  her own time.
  • Then newly-hatched Mothra IV gets caught up in a three-way battle with Battra and Godzilla VI. Eventually, it and Battra ally to defeat Godzilla VI, but Battra is killed in the process. (59)

1)See Rebirth of Mothra III (1998)  The origin of King Ghidorah and other similar creatures is unknown. I speculate that they may be varying types of living “Doomsday Machines”, remnants of a cosmic war fought unimaginable eons ago, and long since run out of the control of their presumably long-dead creators.

2)See Godzilla 2000 (1999)  The origin of this spacecraft remains unknown,

3)See Rebirth of Mothra (1996) The nature of the relationship between the Mothrae and their tiny companions is unclear, but it does seem to  be symbiotic in nature. Their origins are unknown.

4)See Godzilla: Final Wars (2004) Several civilizations with technology in advance of our own are known to have existed around this time, but they were destroyed in a cataclysm said to have been brought about by their own hubris. Only garbled legends and hidden remnants (Mu, Seatopia) remain.  What little information we have about this period makes it clear that these civilizations engineered what we now call “kaiju” to serve as weapon systems.  It is unknown whether the Gigan of this time period was serving a terrestrial or extraterrestrial agency.

5)See King Kong (1933) and Son of Kong (1933) It is now believed that this original Kong  and his so-called “Son” (Since the “Son”’s body was never retrieved, it is impossible to establish its relationship with Kong, but it seems likely that they were close kin.) were simply extremely large apes of a previously unknown species. It is unknown who constructed the ancient wall that stood on Skull Island.  From the photographs that Denham’s expedition provided, it seems unlikely that the natives could have constructed it. Denham's belief that Skull Island was destroyed would later be proven to have been erroneous.

6)(OOC Note: The idea that these two were the same person was not original with me, but I can't remember where I first saw it.)

7)See Kong: Skull Island (2017) MONARCH (See 1973) was a U.S. government organization tasked with studying the creatures they called "Titans" (i.e., kaiju)

8)See Godzilla vs. King Ghidorah (1991)

9)See Frankenstein Conquers the World (1965) The story of the infamous scientist Baron Viktor von Frankenstein (1767-1798) is clouded in a miasma of myths and legends, exacerbated by the liberties taken by his biographer, Mary Wollstonecraft Shelley. How the heart of his creature came into the Nazis' hands is unknown.

10)See Mighty Joe Young (1949)

11)See The Beast From 20,000 Fathoms (1953)

12)See Godzilla (1954) While Godzilla is commonly believed to be a mutated dinosaur, there are still competing theories as to its origins. The fact that there have been multiple “Godzillas” with varying characteristics over the years has clouded the issue.  The name “Godzilla” is an anglicization of “Gojira”, the name of a legendary monster in the culture of Oto Island, near where Godzilla first appeared.

13)See Godzilla Raids Again (1955)  The name “Anguirus” is derived from “ankylosaurus”. Although it was initially believed that Anguirus was killed by Godzilla II, it was later found to have survived.

14)See Rodan (1956)  The fate of the second Rodan is unclear.  That it would be destroyed where the other survived seems unlikely.  The creatures were originally called “Radon” from “PteRAnaDON” (and so it is still called in Japan) but the first English language reports mis-rendered it as ”Rodan”, and so it has remained.

15)See The Mysterians (1957) The exact origins of the Mysterians are unknown, but the fact that they could interbreed with Earth women suggests the possibility that they may be a remnant of one of the ancient Earth civilizations.

16)See Varan the Unbelievable (1958) The creature’s name was derived from a term meaning “father of lizards”.

17)See Mothra (1961) (OOC Note: In the original film, Rolisica is a fictional nation that is obviously a stand-in for the U.S.A. For my purposes, I am treating it as an English-speaking Pacific island nation without a counterpart in our world.)

18)See Gorgo (1961)

19)See Reptilicus (1961)

20)See King Kong vs. Godzilla (1962) It is generally accepted that King Kong II was unrelated to the much-smaller original.  As on Skull Island, there was a barrier on Faro Island designed to protect the natives from the island’s unusual fauna. This wall, while well-made, was more primitive than the Skull Island wall, and is believed to be the work of the current inhabitants.  Godzilla  II looked somewhat different than it had before it was frozen, the first instance of the Godzilla-type creatures tendency to mutate periodically.

21)See Atragon (1963) As Mu was devastated by the Gotengo’s attack, little is known of its culture or history.

22)See Dagorah the Space Monster (1964)

23)See Godzilla vs. The Thing (1964) In future, only one of the two Mothra larvea would be seen. The fate of the second is unknown.

24)See Ghidorah the Three-Headed Monster (1964) It is speculated but unproven that King Ghidorah’s attack at this time was an initial probing attack from Planet X.

25)See Monster Zero (1965) The origins of the X-ists are unknown, but there is evidence that they are a remnant of one of the ancient Earth civilizations.

26)See Gamera the Invincible (1965) There is strong evidence that Gamera was an artificially-created “living weapon”, manufactured by an ancient civilization. The fact that it seemed to take a particular interest in defending human children would seem to indicate that it was programmed to be a defender of humanity.

27)See Godzilla vs. The Sea Monster (1966)

28)See War of the Gargantuas (1966)


29)See Gamera vs. Barugon (1966)

30)See Son of Godzilla (1967)  What relationship there was between Godzilla II and Minilla - if any - is unknown.

31)See Gamera vs Gyaos (1967)

32)See Gappa – The Triphibian Monster (1967)

33)See King Kong Escapes (1967) This “Kong”, although smaller, bore a strong resemblance to the second Kong.  

34)See Yongary (1967)

35)See The X From Outer Space (1967)

36)See Destroy All Monsters (1968)  I'm positing that it took at least a year to set Monsterland up. (OOC Note:  The film gives the year as 1999. I arbitrarily moved it to the film's year of release, because I feel it works better.)

37)See Gamera vs. Viras (1968)

38)See Godzilla’s Revenge (1969)


39)See Gamera vs. Guiron (1969) Terra is a sort of “Counter-Earth”, sharing Earth’s orbit on the opposite side of the Sun.  Its very existence set off a furore in astronomical circles which has yet to die down completely.  Of the Terrans themselves little is directly known, as the last two died in their encounter with Gamera.  UN research teams began exploring Terra almost immediately, but gaining a comprehensive understanding of Terran culture and technology is considered at least a lifetime’s job.

40)See Gamera vs. Jiger (1970)


41)See Yog – Monster From Space (1970)

42)See Godzilla vs. The Smog Monster (1971) Hedorah is believed to be an extraterrestrial organism of unknown origins. (OOC Note:  Making this "Godzilla" an adult Minilla is arbitrary on my part, to explain how "Godzilla"  became more "human-friendly.)


43)See Gamera vs. Zigra (1971)

44)See Godzilla vs. Gigan (1972)

45)See Godzilla vs. Megalon (1973)

46)See Godzilla vs. Mechagodzilla (1974)  “Caesar” is a misinterpretation of “Shisa”, the traditional Okinawan guardian lion statues.

47)See Terror of Mechagodzilla (1975)
