Kaiju

"Monsters are tragic beings. They are born too tall, too strong, too heavy. They are not evil by choice. That is their tragedy. They do not attack people because they want to, but because of their size and strength, mankind has no other choice but to defend himself. After several stories such as this, people end up having a kind of affection for the monsters. They end up caring about them."

- Ishiro Honda.

Kaiju (translated as strange beasts), sometimes romanized kaijyu and kaizyu, also known as Daikaiju (translated as giant strange beasts), are strange entities that appear from human-size to incredibly colossal and are usually depicted attacking major cities and engaging the military, or other Kaiju, in battle.

Overview
The Kaiju themselves vary wildly in size, anywhere from 20 to 500 feet. Their bodies are typically an amalgam of reptilian, cephalopod and ichthyological traits. Nearly all Kaiju observed to date are pentaradially symmetrical, with body parts that typically come in pairs instead coming in sets of five.

The Kaiju have been observed to be highly aggressive, attacking most other entities on sight as well as frequently battling each other. Although spectacular, these fights are rarely fatal as Kaiju possess both supernatural durability and regenerative abilities. They also possess a variety of offensive thaumaturgical abilities as well, such as being able to exhale spellfire that does not extinguish underwater.

The exact population of Kaiju is unknown, but as they have yet to deplete their primary food source, it appears that the Kaiju kill significantly fewer whales than Humans did during the era of industrial whaling. Given both the size and aggressive nature of the Kaiju, this is somewhat perplexing.

In addition to the problem of food, the colossal size of the Kaiju clearly violates the square-cube law, as well as introducing a variety of other scale related problems. In addition to possessing extensive non-Euclidean biology and abnormally thaumaturgically active cells, the Kaiju have a relatively low internal Hume value, lessening the effect of our reality's laws of physics on its body.

Description
It is truly unknown where most to the Kaiju came from even with organizations such as Monarch, the Federal Bureau of Control and even the SCP Foundation searching for it. While some origins were found by the latter with their SCPs, other required them to guess their creators.

One researcher believes that they came from Gaia/Terra as guardians of the natural order, one major example being Battra. Other believes that they were children of Khaos, due to the close connection with the Primordials like the already mentioned Gaia/Terra. One even believes that a couple are the avatars of God himself or even the Devil. It is known that some were created either due to or by human influence, examples being Destroyah and Hedorah for the former or Mechagodzilla 2 and Kiryu for the latter.

No one has yet observed Kaiju mating. They are believed to possess biological sex i.e. produce either male or female gametes. The Kaiju that attacked Hy-Brasil were female and contained several million unfertilized eggs, but did not possess a uterus, likely indicating that eggs are fertilized externally. This would make sense, as the Kaiju's apparently universal aggression towards each other would seem to preclude the possibility of internal fertilization.

Certain members of Fifthism have claimed that the Kaiju are in fact angels of the Starfish and were sent to deliver Judgement upon that world for its lack of devotion, as well as to serve as an example to all other worlds as to what would happen if they did not accept the Starfish into their hearts. Other sources claim that the offence was more egregious, and that some mortals somehow tried to gain entry into the Starfish's Heaven during their Earthly lives. The latter explanation seems more likely, as the vast majority of realities have only small populations of Fifthists, and none of them have been invaded by five-limbed angels.

Myths and Legends
The term kaiju can refer to the giant monsters themselves, which are usually depicted attacking major cities and engaging the military, or other kaiju, in battle. The kaiju genre is a subgenre of tokusatsu (特撮, "special filming") entertainment.

Variations
Over the years, more entities has appeared, while still considered kaiju, may be referred to by a unique title, usually either beginning with the kanji 怪 (kai) or ending in a long "u" in the same vein as kaijū. These include: "Kaiju" may also be substituted for existing Japanese terms such as kaibutsu (怪物), translating to "monster" and used by Varan as well as the Xiliens' designations "Monster Zero," "Monster Zero-One" and "Monster Zero-Two" for King Ghidorah, Godzilla, and Rodan, respectively; seibutsu (生物), translating to "creature" or "organism" and used by monsters such as the Matango, Giant Rats and Zedus as well as in the designation kyodai seibutsu (巨大生物, lit. "giant creature") for Zilla, Gaira and Shin Godzilla; and kyōryū (恐竜), translating to "dinosaur" and used by kaiju who are more dinosaurian in nature, such as Gorosaurus, Titanosaurus and the Godzillasaurus. Furthermore, bakemono (化け物), a term for a type of yōkai that literally means "a thing that changes" and is often translated as "ghost," is used for Godzilla.

Quotes

 * "I genuinely think that, deep in our thousands and thousands and millions of years with nature, there's a chance that an animal's going to come and attack us or eat us or destroy our village or eat our food. It's deep in our DNA that the creature's going to come today or tomorrow. In the modern time, just this small period of time in the lifespan of humanity, we've built these massive cities and we've pushed nature out, but it's still very strong in us that the animal is going to come, and it's going to destroy everything we've built. Our caves have gone from these little huts and caves to 30 story buildings, so our nightmares become 30 stories as well." - A Scholar.


 * "The mass extinction we feared has already begun, and we are the cause. We are the infection. But like all living organisms, the Earth has unleashed a fever to fight this infection. Its original and rightful rulers, the Titans. They are part of the Earth's natural defense system. A way to protect the planet, to maintain its balance." - Dr. Emma Russell.


 * "They may not be angelic in origin, but perhaps they are angels in beauty." - Pangloss.


 * "Hate to pick a fight with The Gloss, but no. Those things are frickin' ugly." - Miss Nexus.

Trivia

 * The reason for why most Kaiju attacked Japan first or only is unknown.
 * The recent term Titan was created and used by the scientific organization Monarch, opposing the EDF, and so has nothing to do with the actual Titans.
 * However some of the actual titans, especially Cronus himself, seem to like the term for unknown reasons.
 * While similar, Dino-Gods aren't Kaiju nor are they Daikaiju.
