Jenova is an extraterrestrial creature that is "a catastrophe that fell from the sky". This is a very perfect parasitic life that evolves, they travel through meteorites in the universe, and once they land on a living planet, they will gradually revive and develop themselves by parasitizing the indigenous people of the place, until they have squeezed out everything that can be extracted from the planet, and then move on to the next planet. Jenova does not belong to the planet of Final Fantasy VII, but is an intelligent life form that inhabits the universe. About 2,000 years ago, Jenova fell in Noluspa (near the current Snow Village) and brought terrible disasters to the planet, which was feared by the ancient species that still existed at the time and called it "a calamity from the sky".

Jenova has a short temperament, high attack power, and is very cunning. It does not take into account what happens after the destruction, and only destroys things other than itself according to instinct, using its "mimicry ability" to spread viruses and invade other living beings. One of the characteristics of Jenova's unusually tenacious vitality is that even if the body is torn apart, the cells can respond to each other and regenerate into their original state. The crater formed by the collision of Jenova with the planet remains to this day, and is now known as the "Great Hollow of the North".

Infectivity:

Jenova is capable of spreading infection through a variety of routes, and they can infect almost any living being that possesses life energy.

No fixed tissue:

Jenova is capable of growing in any situation, it has no fixed functional tissue, and each Jenova cell has the ability to grow into a ** Jenova individual.

Solid-free:

Jenova itself has no fixed characteristics, it can change its image and abilities at any time according to the external environment, and can even copy the image of other creatures as its current appearance, which is why Jenova can freely transform into other people's appearance.

**Individual:

Jenova is able to produce individuals of **, rather than relying solely on parasitism in other organisms.

Modifying the Host:

Jenova has the ability to modify the host, it can adapt the host's body to various situations according to the environment (after all, if the host dies easily, it is not a good thing for parasitic life), and this ability is manifested by the Jenova cluster that Jenova itself parasitizes within the host, when the host encounters an environment that its own body cannot adapt to or has needs that the current body cannot meet, The Jenova parasite uses its properties of an amorphous body (a cluster of parasites can also be seen as a Jenova individual) to reorganize itself into a reconstituted organ that meets the requirements according to current requirements. This is why it is not easy for people infected with Jenova to die, because Jenova is familiar with the vital organs of humans, they can properly protect these vital organs after parasitism, and even if these organs are fatally damaged, Jenova can quickly reorganize his form into an individual with the ability of this organ, to save the life of the host, until the host's own organs are repaired.

Mind Control:

Because the Jenova parasite is able to change its form and function at will, it is able to interact with the host's nervous system (i.e., it can actually reorganize itself into an organ similar to the host's nervous system) to control the host's nervous system.

Psychic Connection:

Jenova instances possess a psychic ability that they can only understand on their own, which their host (if any) cannot perceive in any way, and will only hint at the host through mind control when they deem it necessary for the host to know about it, or directly take over the host's bodily control. Jenova's reunion was largely based on this.

Genova Physiological Habits:

Jenova's intelligence and abilities are closely related to the size of the individual, so upon arriving on a planet, it will parasitize itself on local creatures, and even better if it is a sapient being. When the number of individuals accumulates to a certain level, one of the individuals will become the "leader" and will begin to signal "reunion" to the other individuals. Reunion: Jenova's reunion. This is Jenova's efforts to rejuvenate the scattered individuals and bring them back together to gain higher intelligence and abilities. When its reunion is complete, a Jenova instance will be formed that is more powerful than all previous instances, and the "leader" who previously signaled it will become the main part of the new instance.

Janova in Final Fantasy 7:

The Jenova mentioned in the work generally refers to the prehistoric lifeform in the basement of the Shinra Underworld, but in fact, the lifeform is a Cetra (that is, the ancient species in the game) that has infected a special alien life, and this special alien life is also named after the code name of the lifeform, called Jenova. In the following article, I will make a strict distinction between the two concepts, referring to the extraterrestrial life as Jenova and the Cetra infected with Jenova as the first infected. When the first infected person was discovered, the researchers soon discovered that she was carrying a wonderful life (of course, they didn't know what it was at the time), this life has very wonderful abilities, the most exciting of which is that the biological vitality of this life is quite strong (after all, it was not known at the time that this was due to Jenova's super recombination ability), so it was possible to create a super strong warrior. This was an astonishing asset to the HRE Corporation, which was actively expanding at the time, so it soon established a special research institute, Jenova, hoping to create an all-powerful warrior through Jenova's research. But Jenova is not so kind. It is a parasitic organism in its own right, so this behavior of humans provides a very good route of infection. Because the physiological properties of Jenova are not understood, it has become a top priority to cultivate a complete Jenova individual, but Jenova itself is a parasite, so it is not effective to achieve it through conventional culture methods, so it is urgent to find a suitable cultivation path. At that time, there was no mature bioreplication technology, and it was only possible to start cultivating from embryos, but there were no Jenova embryos at present, so the scientists of HRE thought of a method, which was to cultivate Jenova individuals by "grafting". Of course, they don't know the catastrophic consequences of doing so. As we all know, most of the advanced life is born from the mother's womb, so the researchers came up with a method, that is, to use the uterus of the female creature as a petri dish, and the embryo in the uterus is used as a grafting device, and the development of this embryo is used to drive the development of Jenova cells, and a complete Jenova individual is obtained through this method. At the same time, because Jenova's research itself is mainly military, it is most appropriate to use people as experimental equipment. In this case, Hojo uses his girlfriend to achieve the purpose of the test subject. The end result of this experiment was the creation of a god-like man, Sephiroth. Sephiroth grew up with Jenova (at least that way), so Jenova's parasitism has little effect on him, because his body is almost completely receptive to Jenova's parasitism, so it can be said that it is quite a perfect parasitism. Spurred on by Sephiroth's success, Hojo proceeded to start bioimplantation trials of Jenova cells, but all failed without exception, due to Jenova's own abilities. Jenova itself is a parasite, but its parasitism is quite brutal, when it parasitizes into a living organism, it will use its own consciousness to change the host's original consciousness to achieve the purpose of controlling the host, which is why Jenova can change a person's memory. However, as a host, the autoimmune system will not allow Jenova to parasitize freely, so it will fight against Jenova who has invaded the body. However, Jenova's life is very active (it is impossible to travel through space without a strong vitality). Therefore, in such a confrontation, most of the time it is the failure of the immune system of the human being, and at the same time, the human body will be seriously damaged, especially the mental part (because the damage of the ** Jenova can be repaired, but the mental damage is difficult to repair), so after the experiment, most of the test subjects have completely lost the intelligence of normal humans due to mental damage. As a result, Hojo decided that the experiment had failed, and abandoned the subjects entirely. Of course, there are two types of exceptions, and that is Sephiroth Mother and Son, and Cloud (Claude) and Zack (Zack). The reason why Sephiroth was not affected by this was because Jenova had grown up with him, or had existed with him before his own immune system had developed, so he did not reject Jenova as a foreign object at all; Lucrecia, on the other hand, is Jenova from Sephiroth, which means that she gets it entirely from her own child, so she doesn't resist it as a foreign object (after all, no mother would resist what comes from her own child). So the two of them were infected, but they didn't lose consciousness. The other two exceptions are our protagonist Cloud and his friend Zack. They belong to a different situation, because they were already in a near-death state when they transplanted Jenova cells, especially Cloud was almost unconscious, so in this case they completely lost their mental resistance, so Jenova easily took over their consciousness. At the same time, because both of them were in a near-death state, and their bodies were weak enough to resist foreign objects, their bodies were not damaged. Of course, with the injuries on the two of them at the time, if it weren't for the transplant Jenova, they would definitely not have survived, and the reason why they survived was entirely because of Jenova's amazing repair ability. As mentioned earlier, Jenova is an intelligent parasitic organism that will not easily let the host die, and will use various methods to protect the host's life. The other Jenova infected patients were transplanted in a conscious state, so without exception they had a severe rejection reaction, resulting in the destruction of the entire body, so Hojo's experiment has not been successful. Of course, Hojo's research was still somewhat successful in the end, and that example was himself, Hojo carried out a Jenova transplant in his own body without much rejection through Sephiroth's belief and research on Jenova. Of course, it is also possible that the belief in Sephiroth led to the idea that there was no trace of resistance in the mind and subconscious when Jenova parasitized him, so he inadvertently produced the mental state of the cloud under their serious injury, and thus also produced the parasite of success. So what about the ultimate purpose of Jenova, it can be seen from its method of obtaining life energy, its ultimate purpose is to obtain the life energy of the planet. Therefore, when the number of its own individuals is sufficient, it will gather all the individuals together to form a new entity that is strong enough to achieve parasitism on the planet. This is Jenova's reunion. In the final battle of the planet center in the game, we can see the final result of Jenova's convergence, which is RebirthSephiroth and JenovaSyntnesis. Because only a strong individual can compete with the planet. At the same time, according to the nature of Jenova organisms, when the individual volume (i.e., the number of Jenova cells) reaches a certain level, its intelligence will also increase, so in fact, the so-called reunion is the conversion from biological parasitism to planetary parasitism when the time is ripe. The timing of the reunion is when a "leader" appears between the Jenova parasites or individuals in various places, and the "leader" releases a message and then begins. Sephiroth's awakening happened to bring a "leader" to the previous Jenovas. The reunion officially began. At this time, Jenova, or we can no longer call it Jenova, can be regarded as a real threat to the planet again. Sephiroth itself can be said to be a Jenova individual, so the Jenova life forms on the planet at this time are actually gathered around Sephiroth, which means that Sephiroth can be understood as the brain of the current Jenova. Therefore, in fact, the subsequent Jenova is produced or acted on due to the spiritual influence of Sephiroth, so the subsequent Jenova can actually be said to be Sephiroth, after all, Jenova is only the name of a species, not the name of the current individual, but for the sake of convenience and habit, the place related to the current Jenova consciousness is still called Jenova instead of Sephiroth. But also note the difference between the two. Sephiroth himself is not aware of his origins, so before the events of 5 years ago (based on the game's standard time), he was still living as a normal human, which is actually quite understandable, as Jenova does not have the ability to record his memories through genetic factors, so he naturally does not know his true identity. However, at the time of the Nibelheim incident, he began to take revenge on humanity after learning that he was actually created through a replication plan of the ancient species, and that he was actually an "ancient species". Note, however, that at this time he considers himself an ancient species, not Jenova. Later, he was seriously injured by Cloud's attack in the grinding furnace, and he knew that he couldn't resist the HRE reinforcements who came to reinforce him in this state. And the HRE will not let go of such a person who has committed such a crime, and at the same time, he knows that he is a test subject, and if he falls into the HRE research institute, he will definitely be subjected to various tests (because at this time, it can be completely ignored for its feelings, so any test may happen), and life is better than death. So I chose to jump on my own. If you jump, you won't have to die, but if you stay, it's better to live than to die. This option is actually quite good. What's more, if you think about it as an ancient species, it is also your duty to enter the lifestream and merge with the planet, so Sephiroth finally jumped on his own. (Note: Here is the plot in the use of lo.,And the plot of the root game is different.,Because I personally think lo is more reasonable here.,So it's adopted.,You need to pay attention when reading) After entering Lifestream,Sephiroth got a lot of ancient knowledge from it.,Among them, there's the real situation of Jenova.。 It was from here that he truly woke up and knew that he was a Jenova and not an ancient species. At this time, his Jenova nature began to awaken, and gradually began to guide the progress of the reunion. The reunion must be carried out by **, so Sephiroth has transferred his ** to the Northern Hollow, where there is enough energy to meet his requirements, and at the same time, he is not easily disturbed by the outside world. However, due to the planet's own mental defense mechanism, the reunion signal of Sephiroth has only gradually begun to take effect until now. That's why we can see the process of reunion in the game. It can be said that Jenova's reunion in the game went very smoothly, although there were some exceptions, that is, Cloud regained his consciousness with the power of Lifestream and broke away from Jenova's mind control; Lucrecia, on the other hand, because of the inaccessibility of the location and the fact that she is more conscious, has survived the hints and control of the reunion, rather than succumbing to the nature of the reunion. So after the reunion is over, is the story over after the newborn Jenova instance is defeated by the protagonists? The answer is no, we also mentioned before that Jenova's life ability is quite strong, and defeating them like this alone will not get effective results, but it doesn't matter if they are always there, but after defeating Jenova, something happened that we all know, and that is the Holy outbreak. Holy didn't destroy Jenova's wreckage, but he didn't, so a small amount of Jenova's wreckage was brought to the surface and scattered across the planet while Holy and Metoer were fighting. The remains of these jenovas will also try to parasitize people after they come into contact with humans, and the effects of people's own immune systems fighting these jenovas that invade their bodies are directly reflected (mental pain and strange patterns on **). People who don't know the inside story interpret this symptom as the anger of the planet, and believe that it is a plague that the planet has brought down to punish people for their previous crimes. Call it "Star Marks". However, at this time, the remains of Jenova had already been left after being bombarded by Holy, so the vitality and vitality were far from enough to be easily infected (that is, the infectivity of Jenova in the previous HRE experiment was completely incomparable), so most of the affected people were children (children's immune systems are not very developed, so they are easily infected), and weak patients (such as Rufus, a type whose immune system has been compromised after a serious injury). Because the body of a healthy person can easily suppress these "viruses" that are not highly infectious. Of course, at this time, Jenova is not only left with these low-infectivity (relatively speaking) remains, and there are still some who are not involved in the reunion, that is, the first level of the infected, because the reunion itself is a matter between different Jenova individuals (and parasites), and the first infected person is just a specimen that is still alive, so this specimen will naturally not participate in the reunion. In fact, I always felt that I didn't know where this thing went. But now I can understand that in fact, in the game it is this place that laid the groundwork for AC. When the main body of Jenova is destroyed, this specimen becomes the main part of Jenova's**. We know, and Jenova knows, too, but because this specimen doesn't have enough life to plan, Jenova uses his residual consciousness (actually Sephiroth's, as for why this is the case, as explained in more detail below), and uses the power of Lifestream, to create three instances like a planet to create a weapon, and these individuals are used to complete its purpose of reorganization. These three individuals are created by their minds, so they call themselves minds. This is also the reason why they were able to return directly to Lifestream after they were defeated in the end. Because they are not natural creatures per se. In other words, they are essentially similar to the weapons made by the planet, except that the idea of creating them is not the planet itself. Of course, it is important to note that although they were created by Jenova, they are not Jenova living beings themselves, so they do not have an important property of Jenova, which is infectiousness, and they also lack telepathy between Jenova instances, which is why they don't even know the exact location of the last remaining Jenova samples. In essence, they are the same as any other creature on the planet, but it is Jenova's who controls them, or rather creates their minds. Or rather, we can call her Sephiroth at this point. At the end of the game, Cloud defeats Sephiroth in an unknown place, after which we can see that Sephiroth's body gradually disappears, and he transforms into Lifestream and disappears. Herein lies the problem, there is nowhere else in the game that this method of death is shown, not even when Aeris dies (forgive me, Sister Aeris. t.t), so this description illustrates the problem that the battle at that time was not a battle with Sephiroth's **, but a battle with Sephiroth's soul. Sephiroth fails, and his consciousness becomes part of Lifestream. But just as Aeris's consciousness didn't disappear as a result of entering Lifestream, so did Sephiroth's will, which they are still fighting in Lifestream. Because Cetra and the planet's spiritual abilities are quite strong, if you want to defeat Aeris and defeat the planet, you must recover it from the outside world, but the current ability of the Jenova remnants in the outside world is limited, not only can it not produce a leader who can re-lead the reunion, but it can't even control the host. The only individual who can produce a leadership function does not have the vitality of its own to expand. Therefore, Sephiroth used the previous methods of the planet to create his own "weapon" to achieve his own goals. He used the planet's energy to create the trio and influenced them with his own consciousness. It can be said that in fact, the trio is the embodiment of Sephiroth. The first task of the trio is to find a sample of the first infected, as they need a true Jenova instance to lead the reunion, as well as to enhance the infection ability of the Jenova wreckage in the current world, because the reunion can only be carried out if the host can be controlled. However, the trio themselves do not have any way to increase their ability to infect (as they are not actually Jenova lifeforms at all), so they can only be changed by the will of Sephiroth through the abilities of Lifestream. Therefore, they collected astral marks to strengthen the vitality of the Jenova cells in their bodies, and in order to do so, they brought these patients to Forgotten, as this is the place that is currently known to Sephiroth to be able to connect directly to Lifestream, where they can directly use LifeStream's energy for reinforcement. Therefore, the main purpose of bringing the children to the city is to strengthen the vitality of the Jenova cells in their bodies through the power of Lifestream. There is a line here that is more sensational, and the brothers in this line refer to the people who are infected with Jenova cells, because it can be said that all Jenova clusters are brothers, and the so-called planet hinders growth, in fact, because of the situation where human beings (planets) themselves have an immune mechanism against Jenova. In fact, this passage is a reference to the Jenova Horde on the children's body of the Great War on the Ruins, as Kadaj obtained a sample of Jenova and thus became a Jenova entity in the truest sense of the word. In this case, Sephiroth felt that the time was ripe, so he embodied his thoughts directly on the Jenova instance, and thus the phenomenon of Kadaj becoming Sephiroth (speaking of which, this is an inference that overturns when I didn't look at AC before). Because Kadaj itself is an energy being, although they have their own consciousness, they are born by the will of the sephiroth, so they can easily be used by the sephiroth. In the ensuing battle, Cloud defeated the Jenova instance, which was equivalent to directly destroying the body that Sephiroth could use directly, so Sephiroth's consciousness returned to Lifestream, and only Kadaj, who was finally abandoned, was still here. Of course, such a situation also ended up infuriating Aeris, or the planet. Therefore, at the end of the AC, it rained heavily, and this rain was the same as the nature of the previous three people's ability to strengthen Jenova's infected body, but the object of action was different. All of Jenova's wreckage was excreted from the body and eventually returned to Lifestream. That is, after such a rain, the danger of Jenova has passed. In fact, this danger should be atonement for the human beings themselves, but in the end, it was the planet that stepped in to solve the problem, perhaps because the planet became tolerant due to the influence of Aeris. Of course, the specific relationship between Aeris and the planet will not be detailed here, but the nature of Lifestream and the characteristics of the planet will be written in the next study, where the relationship between Aeris will be described in detail. Finally, I would like to mention the "mother" in the lines of the trio. In many cases, they think that their mother is Jenova (in this case, the name of the First Infected), because as mentioned earlier, they were actually created by Sephiroth's consciousness, and Sephiroth has always believed that his mother is Jenova (also saying the name of the First Infected), so they have this thought. But then after Sephiroth was defeated, the coercive influence of Sephiroth's consciousness disappeared, and Kadaj had the freedom to think about it on his own, so after hearing Aeris's voice, he felt a feeling similar to his own (after all, he himself was directly created by the energy of Lifestream), so he felt a sense of motherhood. In addition, in a sense, Aeris has now merged with the planet, and it can be said that the consciousness of Aeris is the consciousness of the planet to a certain extent, so the life born of the energy of the planet can indeed be called Aeris the mother. The phrase cloud can also be understood in this way, because the planet is the mother of all life.
