Kaiju are monstrous creatures that come in different sizes and shapes. All of them have different features, some more humanoid than others. Every kaiju possess a Core (核, Kaku), which is their vital organ and weakness, inside their body, and since every kaiju comes in a different type the location of the core changes accordingly.

Powers and Abilities[]

All kaiju gain their powers from their Uni-organ (ユニ器官, Yuni-kikan), an organ containing their specific powers.[2] Despite their common nature, each kaiju possesses different abilities and powers, so it's quite rare to find similar kaiju.[1]

Some powers most kaiju have in common are super strength, proliferation abilities, and great fortitude levels. Some of them are able to fly[1] and the most complex are even able to practice human language and, through that, can talk.[1][3][4]

Classification[]

Power[]

Every Kaiju is given a Fortitude level (フォルティチュード, Forutichūdo) which is a way for the Defense Force to measure the creature's power and its potential threat to humanity.[5] According to the Fortitude level, Kaiju are then classified power-wise.

Yoju[]

Yoju ( () (じゅう) , Yojū, lit. "Residual Beast") are smaller kaiju who accompany their Honju. There are usually numerous Yoju to assist a Honju, and some kind of Yoju can have proliferative organs as well. Yoju can appear in many ways, by traveling routes made by the Honju, latching onto the Honju, being created by the Honju, and more.[6] Some Yoju can have a fortitude number above 6.0, thus being a Honju-level threat while still being a Yoju.

Honju[]

Honju ( (ホン) (じゅう) , Honjū, lit. "Main Beast") are usually the biggest and most powerful kaiju, and the one who generates and guides all the other Yoju through their proliferative organs. Their fortitude level is usually above 6.0. A Honju with a fortitude level of 6.4 would require an entire Platoon of Defense Force soldiers to defeat it, and only a Captain or Vice-Captain could defeat one alone.[7]

Daikaiju[]

Daikaiju ( (だい) (かい) (じゅう) , Daikaijū, lit. "Large Monster") is a special category of kaiju. It is the name given to particularly strong kaiju, whose fortitude level exceeds the number 8.0.[5] Having appeared ever since the Meireki era,[8] these kinds of kaiju are part of the strongest category, with their power not necessarily being linked to their size, since Kafka, who has a fortitude level of 9.8 in his kaiju form,[9] the highest seen thus far in the series, defeated multiple kaiju much larger than him in size. Due to their incredible power, Daikaiju can also be Honju and guide their group of Yoju (like Kaiju No. 10 with the Preondactyl Kaiju).[10] In spite of that, Daikaiju are not above operating individually on their own. According to Isao Shinomiya, the Defense Force presently has around two dozen elite officers who stand a chance at taking on a Daikaiju, less than ten in single-combat and when fighting a numbered Daikaiju, the number gets even lower.[11]

Identified Kaiju[]

Identified Kaiju ( (しき) (べつ) (かい) (じゅう) , Shikibetsu Kaijū) are daikaiju that are extremely powerful and have a fortitude level of 9.0 or higher. Even if their fortitude level is lower than 9.0 (like Kaiju No. 9, who had a fortitude level of 8.5 before shedding its skin), if there is a need for identification, then a codename will be given. While daikaiju of this caliber have always appeared in history, their identification numbers were implemented only after the fortitude observation system was established.[12]

Because neutralizing these types of kaiju takes a significantly longer time, the Neutralization Bureau gives them numbered codenames in order to identify them.[6]

According to Keiji Itami, it would take multiple captain-level officers to defeat an Identified daikaiju.[13]

When they are killed and weaponized, the corpses of Identified Kaiju become the core of Numbers Weapons.[14] When wearing them, the user can have visions of the Identified Kaiju used as core,[15][16][17][18] as well as access their memories of their past owners through Ghosts.[17]

Up until know only fifteen Identified Daikaiju appeared in history:[19]

Trivia[]

  • According to Juzo Nogizaka, an unnamed country is experimenting kaiju-to-human tissue transplants.[35]
  • Kaiju has been theorized as being born from the immense energy produced by the faults in the earth, acting upon the underground substances, plants, and animals to produce them.[36] It was further elaborated as the Mysterious Larva was born from the "Dragon Veins" deep within the earth after the hearts of the warriors formed a core.[37]
