~ Narrator |
Houkai (or Honkai), also known as Collapse, are the titular secondary antagonists of Guns Girl Z and its sequel Honkai Impact 3rd. They appear in all its different forms of media as major antagonists. They are the central threat to all humanity and appeared in many different worlds to cause the end of all civilizations in multiple universes. The Honkai are like the secondary dominant race of the world and grow with civilization and seek to destroy it to fulfill God's desires.
The Honkai are not actually physical threats but a supernatural phenomenon that manifests itself in many ways, including infectious diseases, plagues (and even digital viruses), infected humans (zombies), natural disasters (such as sentient tornados, tsunamis etc), Honkai beasts, and its primary form; the Herrschers, humans with superpowers that defy physical laws. The Honkai threat will be the primary adversary for the player (Captain of the battleship Hyperion). Interestingly, Honkai grows and evolves with human civilization and technological progress, and appears to be dedicated to its ultimate goal of destroying humanity by all means necessary. Ironically, the Honkai energy is also extremely useful, and several human organizations have harnessed it to generate massive power.
History
The Houkai have no background and it's speculated the Houkai, or the Will of God, exist since before the creation of the universe. Million years ago, the extinction of the dinosaurs in the Cretaceous period happened because of the first outbreak of Honkai but it's unknown what they showed up before humans could have existed.
Despite being represented as monsters, the Houkai is actually a sentient cyclical natural disaster phenomenon, a rhythm of periodic adjustment of the universe that appear once in a while to start the end of a civilization. Every once in a while, the Houkai will break out in some unknown form, it can be in form of zombies, plagues, digital virus, meteors, tsunamis, earthquakes or even monsters and beasts. 50,000 years ago, when humanity reached the top of its existence, Houkai evolved in the form of Herrschers and caused the eventual destruction of mankind by the hands of the last Herrscher after decades of intense war, Herrscher of the End. This Herrscher, who was later sealed inside of the moon by Dr. MEI, became the new Houkai God in the ancient legends.
However, a few humans managed to survive the Apoclaypse and repopulated the planet again; humanity had another chance to fight again the creatures that once caused their extinction. After million years fighting the Houkai, the outbreak time of the Houkai was considered irregular and difficult to predict the Schicksal organization was founded thousand years ago to prevent disasters like the Black Death, started by the Herrscher of the Corruption from happening again.
In the final chapter of Houkai Gakuen 2 Reborn Era. It was revealed that Honkai Energy come from another universe outside Imaginary Tree under control by The Will of Honkai. It is used to destroy other civilizations and the entire Imaginary Tree itself. And the Herrscher of the End is their ultimate weapon. In the from of girl name Kiana Kaslana. 84000 years ago, Dr. Mei has created the biological AI called Alaya from Kiana's body to trap civilization in an artificial cycle. If humanity is lost, computer will reset the civilization as long as Kiana wishes. The cycle is broken because the Will of Honkai corrupted the system to force humanity to beat it or be destroyed permanently.
In Honkai Impact 3rd, Cocoon of Finality is responsible to all of Honkai disaster in this game. Unlike Will of Honkai from Houkai Gakuen/Gun Girl Z however, Cocoon of Finality doesn't want to destroy, but embrace civilizations. And if civilizations failed to embrace the Honkai, Cocoon will use Herrscher of The End to reset the timeline and restart the process all over again. Cocoon has also destroy other civilizations from other planets like Mars and Venus on solar system before come to earth. But it see those civilizations and impossible to embrace and leave them to die. When the civilizations died, their leave behind datas created bubble universes float in Sea of Quanta. That will soon fate to die without the Ether Anchor.
Due to Houkai Gakuen 2 is no longer available outside of China and Japan, informations from this game should be taken with a grain of salt because Mihoyo could consider this game as no longer canon to the rest of Hoyoverse. Or only partically correct the rules of honkai from one game are not appiled to other games.
Overview

The manifestations of Houkai are unpredictable and impossible to describe by normal means. Some say even humanity's sins are related to Honkai energy; it can be wars, infectious diseases, climate disasters, comet impacts, and even the arrival of giant monsters are all possible. By all means, any disaster can be considered a Honkai doing in noncorporal existence.
According to the interpretation of Shicksal studies, the Houkai is the unpredictable will of God, the creator of universe who often uses their will to destroy worlds he is not sastified with. But from the results, it bring about a large number of extinctions of the world's dominant species. In forms of monsters, the Honkai have no specific targets and desires to destroy and kill everything it sees in its path.
As a substitute for Honkai will to punish human beings, the Honkai beasts has continued to create more new attitudes as the human activity has gradually expanded. However, according to Schicksal research based on it form and destructive power, is divided into seven types: Radical level, Cavalier level, Ballista level, Chariot level, Sanctuary level, Emperor level, Trial level.
According to Schicksal database, the five types of Radical level, Cavalier level, Ballista level, Chariot level, Sanctuary level is actually a low-level Honkai beasts. It should be noted that these five types Honkai beasts are named based from their form, not from their strength. In other words, there is no such thing a Honkai beast Radical level increase to Cavalier level. Also, these five types Honkai beasts doesn't have a specific name. The two types, Emperor and Trial level are known as the dangerous Honkai beast. Once these two types Honkai beasts are identified, they will be given a specific name, usually the name will come from a myth.

With it's dangerous criteria, there are more Honkai beast above it's ability, it will be classified as Emperor level and Trial level. This Honkai beasts often have a huge body shape and special abilities. For example, Parvati as Snow Mountain Goddess, has the power to manipulate snow storm. Assaka, as Ashvins (Divine Twin Horsemen), can separate it body, and can also shoot thunderbolt to attack the Valkyries.
Trial level Honkai beast
It's only name as Trial level Honkai beast because it has the ability to cause large-scale natural disasters and has a huge size beyond known species.
There are only two Trial level Honkai beasts that have been confirmed: "Chiyou", that appeared in Shenzhou and "Benares", the dragon who invaded Schicksal Headquarters.
Judging from it 'srepression of the Trial level Honkai beasts, it's extremely difficult to destroy them. With it frighteningly large body and indestructible outer armor, most of human attack methods are difficult to cause substantial damage to Trial level Honkai beast.

Only by relying a weapon with Divine Key level, breaking all of it's cores and exhausting it body, can stopped Trial level Honkai moving. This requires not only a strong weapon, but also a collaborative effort of large team.
Cataclysm Level - Herrschers

Herrscher(s), roughly translated from German to Ruler, or also known as a "God", Will of the Houkai, Will of the God and Humanoid Houkai (a mortal or immortal entity who ascended to the world of the Gods) - is an entity that has merged with Houkai energy and has given into the will of the Houkai God to destroy the current era of their civilization and is the strongest manifestation of the Houkai known in the univeerse.
Most of them are humans but new side-stories showed that there are Houkai and Herrschers in many other populated worlds of the universe. They are considered to be extremely powerful in all aspects, in such that S-Rank Valkyries can't guarrantee winning alone without the help of dozens more. The Herrschers are the supreme form of the Houkai and its strongest manifestation in the physical world.
Since they need a human body to host their astral (or Thought-Form), they are not invincible and can be killed if their physical forms/hosts are destroyed or disabled if their core is extracted from their body. The true form of a Herrscher is a gem that can be inserted inside of a being's physical body, allowing them to possess their vessel and have a physical body. Most of the Herrscher are genderless but once they take control of a human body they gain the gender of their vessel, becoming one with them and officially becoming a part of their vessel, like a new persona or personality.
However, after Elysia realm and Project Stigma story arcs. It was reveal that Herrscher persona never truly exist in Honkai Impact 3rd countinunity and Cocoon simply turning all Herrscher host insane by accident. But Elysia sacrifice allow Herrscher born after her era able to retain their sense of self which is necessary step for humanity to past Honkai test and be embrace by Finality. While Will of Honkai in Gun Girl Z can selectively choose people who are misantrope to be herrschers and can assert their will on to them if they decide to not take vengence on humanity.
Herrscher can live without air as show that Kiana self quarntine on Moon after Honkai Impacrt 3rd; part 1 finally without issue. The same is also true in Houkai Gakuen 2 when in Reborn Era final chapter when the crew go to the moon to defeat Honkai God, Kyuusyou and Mei don't need Oxygen suit to survive in space.
Energy
Houkai releases a kind of energy that has never been seen in the past technology, it's called "Houkai Energy", an energy that can be used in infinite methods, including in the creation of technology such as robots, ships, super-weapons and vehicles. The efficiency of Houkai can far exceed any energy available in the world, but if a living being is exposed to this kind of energy, they will become zombies or monsters.
In rare cases, there are people who can endure the Honkai energy and awake their natural Stigmata. In even rarer case, person with very high Honkai resistance can become a Herrscher if it chooses them as humanity's Harbinger of Doom. If it the energy rejects them, they will become mindless and weak zombies with no persona and will. When Houkai energy in an area reaches 1000 HW (Houkai Watts) or higher, there is a small chance that someone may absorb sufficient Houkai energy to become a Herrscher.
