Homeostasis

Homeostasis (ホメオスタシス, Homeosutashisu) is a formless, god-like entity, or group of entities, that maintains the balance between good and evil in the Digital World. Because it has no body, it has to possess other people's bodies to communicate.
=Appearances=
==Anime==
======
Homeostasis is the entity that chose the Chosen Children and created their partner Digimon, Digivices, and Crests. It is assisted by Gennai and other beings like him. In "The Clashing Ultimates! War Greymon VS Metal Garurumon", Homeostasis chooses Yagami Hikari as its host, because she is the only one of the Chosen Children who could hear it, and speaks through her to reveal to the Chosen Children why they were chosen.
Homeostasis shows them a holographic recording of the past, when Gennai and his associates were preparing for "the moment when the world would be overrun by darkness" in the basement of what the Chosen Children know as Vamdemon's castle, and reveals to them that it chose them back in 1995 when they witnessed Greymon and Parrotmon's fight, then created the Crests and Digivices based on data it scanned from the children at that moment. It also shows them the day the Dark Masters attacked and stole the Crests, how Gennai escaped with the Digivices and Digitama (also showing the loss of Tailmon's Digitama), the hatching of the partner Digimon from those Digitama, and how they waited for the children to arrive.
It is never referred to by name in the anime, but was given the name "Homeostasis" in the novelization of the series.
======
Homeostasis is opposed to Yggdrasill and aims to keep Meicoomon's powers from disrupting the balance between the Real and Digital Worlds. It is assisted by Hackmon, who acts as its messenger in the place of Gennai, who is missing.
In "Confession", Homeostasis possesses Hikari again while she is at school and, in her body, leaves to find the eight partner Digimon. It warns them of the existential threat that Infected Digimon pose to the balance between the worlds and says that the only way to prevent the total destruction of the Digital World is "a great sacrifice", but it loses its control of Hikari before it can say anything else. Himekawa Maki, who had eavesdropped on the meeting, explains to the Digimon that it was talking about the Reboot.
A flashback in "Loss" shows Homeostasis possessing Himekawa Maki during the battle between her group of original Chosen Children and the Dark Masters. Homeostasis appears to be the one to give the other partner Digimon the power to evolve into the Four Holy Beasts.
In "Coexistence", Homeostasis has decided that Meicoomon has become too powerful and must be destroyed, and tasks Hackmon with killing it. It also believes that the Chosen Children have failed to do anything to stop Meicoomon, are no longer of any use to it and must no longer interfere with its will, so the Digital World starts to reject them by randomly changing its terrain and subjecting them to angry Digimon attacks. When the Chosen Children confront Meicoomon in the real world and Jesmon joins the battle, Homeostasis possesses Hikari again to try and convince the Chosen Children not to interfere, but they reject its insistence that the should forget about their friendship with Meicoomon, and Hikari forces Homeostasis out of her.
======
After Ohwada Lui explained that Ukkomon's ability to grant wishes came from him having a connection with a "greater being", Yagami Hikari thought that said greater being had to be Homeostasis.

======
Homeostasis is a digital entity meant to take care of the Digital World, after Yggdrasill had gone berserk in the past and attempted to destroy the human world. Homeostasis was created as a response to that, to work as Yggdrasill's successor and to be a more calm and protective god. Wizarmon describes it as having "infinite knowledge" but "not being all-knowing".
In "Xros Alliance! The Final Battle in Odaiba!!", Ulforce V-dramon and Wizarmon talk about how it once predicted, based on the data from scanning the Digital World, that a "two-headed dragon" will come and destroy both the real and Digital Worlds. The prediction comes true in "Xros Stars! Like a Falling Star!!" when Shademon (Nene Ver.) forces a DigiXros between Millenniumon and Dark Knightmon (Lilithmon) to create Zeed Millenniumon.
Homeostasis is seen in a flashback in "Xros Miracle!! Reel in a Sliver of Hope!", where Bagramon questions it about the world's justice before his fall from grace.

======
Yagami Hikari heard a voice in Episode 53, "Clash! The Ultimate Digimon", though no one else could hear it. After War Greymon and Metal Garurumon's fight, Hikari talked to a mysterious light that, once again, no one else could see or hear. The light confirmed it wasn't their enemy, then took over Hikari. It sent the Chosen Children into the past then introduced itself as the one who wishes for stability in the Digital World. Tailmon and Izumi Koshiro realized that was not Hikari talking, but someone using her body, and it explained that they prepared eight Digitama for the time when the world would be covered in darkness, starting from creating the Digivices and Crests from the Chosen Children's data, which made Yagami Taichi realize they were the ones that chose them. The light confirmed this, explaining that the light they saw in Hikarigaoka four years ago scanned their data. However, the Dark Masters found out about their plan and tried to steal the Crests. A young Gennai protected them from Piemon by taking the Crests and Digitama with him to File Island, but due to the interference of his pursuers, lost Tailmon's Digitama, and many years later, the Chosen Children and Partner Digimon finally met. The light was unsure about what they should do next, but believed they could find out with their own abilities. The light then left Hikari's body and returned them to the present, with Hikari having no recollection about what happened.
Like in the anime, Homeostasis is never named, with its textboxes merely using the portraits and name of Yagami Hikari, whose body it possessed.
======
Homeostasis possesses Yagami Hikari to talk to Taiga in the Colosseum 40th floor Free Battle: "Light Priestess". It uses Taiga's battle with Hikari to see if Taiga has the light to save the Digital World and the Digimon, deciding he does after Taiga defeats her.
