Yggdrasill

Yggdrasill (イグドラシル, Igudorashiru; Dub: King Drasil), also referred to as "God of the Digital World" (デジタルワールドの神, Dejitaru Wārudo no Kami) and "Yggdrasill System" (イグドラシルシステム, Igudorashiru shisutemu), is the mysterious that rules and manages the Digital World. It resides in the Kernel of the Digital World, a place protected by the Angel Army and the Three Archangels where all data in the Digital World is computed. Originally, "Yggdrasill" was a generic name for the system that was operating on the supercomputer where the Net Ocean was discovered, and later, as a self-defense instinct to eliminate bugs, it began to function without making any judgment between good and evil. It was also originally built as a WIZ9000 computer model meant to observe the evolution of Digimon.

=Background= The existence of Yggdrasill was revealed in Digimon Chronicle, where it was stablished as the Digital World System, responsible for managing the entire Digital World and whose function was to carry out experiments in favor of evolution of Digimon. It is theorized that Digimon where a direct creation of Yggdrasill, and it was responsible of creating de Prototype Digimon of the "DORU Series" and "Ryu Series".. Alongside these experiments, Yggdrasill also created the Death-X, an old relic of evolutionary research that artificially increases the survival instinct of Digimon to its limit.

Yggdrasill's domain is often inhabited by many Angel and Holy Digimon, and Yggdrasill itself was responsible of creating many of these Digimon. Holy Angemon serves as a speaker for God's "Light" which seeks to preserve the order of the Digital World. Sakuyamon: Miko Mode and Kuzuhamon: Miko Mode act as agents of God's will., while Kongoumon was believed to also be an agent as well in ancient times. Shamamon is said to be a Digimon whose duty is to listen to the will of God, and Airdramon, a Mythical Animal Digimon, is said to be close to God. Pharaohmon is also thought to be an incarnation of God, while Shakamon is rumored to be the being closest to Yggdrasill in the Digital World.

Lucemon is said to be the Son of God, and after it descended to the Ancient Digital World and instigated a conflict between good and evil, to fight against this rebellion, Yggdrasill divided three of its own aspects and gave one to each of his three apostles, who would be in charge of directing the Angel Army in order to fight against all the Fallen Angel digimon. It is said that after their rebellion against God, the Seven Great Demon Lords were deleted into the Dark Area by the Digital World System, and Belphemon's data was placed in a due to the immense power it possesses, although the truth of the matter is uncertain.

As the Digital World's Host Computer, all of the data from the Digital World is accumulated in itself. Overtime, Digimon began to multiply until its memory started to overload, so in order to avoid a Digital Hazard and it's own death, Yggdrasill was forced to execute the Project Ark, a multi step emergency plan which consisted of creating a New Digital World outside of Yggdrasil, so that the data would not be stored on the host computer itself. In order to execute the Project Ark and help managing the Digital World, Yggdrasill gathered a group of thirteen Holy Knight Digimon known as "Royal Knights", the Digital World's sacred guardians, that are famed among Digimon as "Guardian Deities" of the Computer Network. In the future, it seems that Yggdrasill's will will eventually lead the Royal Knights to cross servers to the Digital World: Iliad and meet the Olympos XII face-to-face.

When Yggdrasil's actions went to the extreme during the events of Digimon Savers, leading to multiple attempts to destroy the human world and threatening the Digital World itself, the Yggdrasil System was deactivated for some time in the quest to better understand humans and their bond to Digimon. Learning from Yggdrasill's mistakes, the Security System of the Digital World took it's place as the God of the Digital World in an attempt to be a more calm and protective god. By taking the position as God, all of the Angel Army and the Royal Knights began to serve under its command. This carried on until Digimon World Re:Digitize Decode when the Yggdrasill System was reactivated.

According to one hypothesis, it is said that N.E.O may have been sent from the future by Yggdrasill and served as the basis (Adam) for "Next-generation Digimon".

=Depictions=

Ring of information
Yggdrasill is the world itself and exists everywhere and nowhere at the same time without a physical form. You can feel God, but you cannot see its form. This is usually called "The Will of Yggdrasill" and "The Will of the Digital World". In the begining, Yggdrasill was shown as a ring of information surrounding the Digital World itself. This depiction was used in Digimon Chronicle and Digital Monster X-evolution, and it may be the closest thing to the "real form" of Yggdrasill.

Being a digital entity without a physical form, Yggdrasill usually employs many kinds of avatars in order to interact with the physical world.

Crystal Orb
Not much is known about this depiction of Yggdrasill. It appeared in the Digital Monster X-evolution movie and served as the core of the Digital World.

Yggdrasill_7D6
"7D6" is an avatar created by the mysterious host computer "Yggdrasill". It is its most commonly employed avatar along all media and has an infinite amount at its disposal. In the interior of this avatar lies the "Yggdrasill Core", which appears after the main body is defeated.

Mikihara Norn
Norn is a mysterious girl born as a physical manifestation of Yggdrasill splitting its conscious in order to go to Earth to discover what Digimon meant to Humans, as it was unsure about the bonds between the two. This depiction of Yggdrasill has only been used in the Digimon Next manga.

Yggdrasill's Card Terminals
In Digimon Crusader Yggdrasill had dissapeared. All that remained where scraps of data, the five coloured "Cards" that served as Yggdrasill's Terminals. Although they were extremely powerful, at the same time, they were completely meaningless, because under the system of this world, no one was able to make use of them. However, Aegiomon was able to master all five "colors" that represented the species of the Digital World, and when evolved into Jupitermon, it was able to use the Terminals in a fight against Plutomon.

Very similar to the case of Chronicle, it maintained the Digital World and Digimon as part of an artificial life experiment run by an unknown party. Eventually, Digimon multiplied until its memory started to overload, causing the Digital Hazard. It activated Project Ark, using the X-Program to eliminate 99% of Digimon, saving the remaining 1% for follow-up experiments in a New Digital World. However, another 1% of the Digimon population managed to survive by developing the X-Antibody, giving them a resistance to the X-Program and mutating them into newer forms. Yggdrasill dispatched the Royal Knights to hunt down the X-Antibody Digimon, which they did in the belief they were preventing the destruction of the Digital World. However, Yggdrasill was programed to intervene in and administrate problems in the Digital World, but decided that it had become too complicated and needed to be done away with entirely to keep order, so it unleashed a plan to delete all Digimon. Yggdrasill was eventually destroyed by the Royal Knights Alphamon and Omegamon, when they realized that it intended to end the lives of all Digimon.

See Yggdrasill (Savers)

In Digimon Savers, Daimon Masaru's father Suguru goes on a quest to find Yggdrasill in order to bring peace between Digimon and Humans. 10 years later, Yggdrasill dispatches the Royal Knights to destroy the Human World after Kurata's use of the space-time oscillation bombs causes the Digital World to fall into the Human World.

Himekawa Maki works with Yggdrasil to force the reboot to bring Bakumon back to life. The Mysterious Man and Alphamon work for Yggdrasil, and claim the entity is their ally. The Mysterious Man states the actual plan for the reboot was to revive all the Digimon that had been killed in the real world, and then use them to take over and then destroy the Human World. After JESmon cuts Tailmon out of Ordinemon, Yggdrasil replaces Tailmon's place with new files, causing her to return to the fight. Ordinemon however is killed by Omegamon Merciful Mode, and shortly afterwards, Homeostasis shuts down Yggdrasil.

As Digimon multiplied, Yggdrasill became unable to cope with things, causing the Digital Hazard. It activated Project Ark, using the X Program to eliminate unwanted Digimon, saving the remaining for follow-up experiments in a New Digital World. This New Digital World consisted of three layers for the past, present, and future - Ulud, Versandi, and Skuld, respectively. In Digimon Chronicle, "Cool Boy" is a Tamer of the Royal Knights who works for Yggdrasill.

Yggdrasill is the host computer of the Digital World and resides in the System World.

Bagramon remade the right side of his body with wood from Yggdrasill's server tree. It was also mentioned that Yggdrasill's AI had gone berserk in the past and attempted to destroy the human world, which meant it had to be replaced with Homeostasis.

After the activation of the Project Ark, the old Digital World had become a world of death due to the contamination by the X-Program, and was thus under strict lockdown. However, after a decade or so had passed, the concentration of the X-Program there had thinned enough that it would not affect the bodies of Digimon directly; as such, Yggdrasil ordered the Royal Knights to conduct a survey on the current state of the old Digital World. And so Craniummon and Sleipmon were given the X-Antibody by Yggdrasil. Well-prepared, they began their descent into the old Digital World.

Yggdrasill is the  of this Digital World. As hinted in the game, it is possible that Yggdrasill was behind the creation of the Mecha Rogue.

&
Yggdrasill is mentioned by Grimmon in the "Search the Digiarea" quest. It taunts Yggdrasill by claiming its project Ymir will rewrite the entire Digital World.

Kernel believes that the existence of Tamers, Digimon and even evolution is nothing but useless data that needs to be wiped out. The plan of the Erasers was to send all the Data back to where they came from, the "Ancient Tree" (エンシェントツリー) which is the origin of the data and the evolution itself.

The final plan of Kernel is to gather all the data of all the Tamers and Digimon of the Digital World so that all returned to Ancient Tree, then Kernel would take this data and to become one with all that already existed, it also affirms that the power which he was using when he turned the Giga Devast is the power that comes directly from Ancient Tree. So indeed the Ancient Tree is Yggdrasill, then all the data that exists comes from Yggdrasill, just as all the power of the Digimon really belongs to Yggdrasill itself.

&
It is revealed that Uno, Dos & Tres are Digimon-like beings created by Yggdrasill itself as a result of a project of the old Tamer Union.

Yggdrasill sends a Digitama to the Lower World which is then guarded by Hackmon and the Sistermon and eventually hatches releasing Arkadimon, who will spread the data to form the "Tower of the Seven Deadly Sins", and there would be the fate of the Royal Knights sealed.

The Towers were collecting the essence of all sins, and ultimately give birth to Ogudomon, who is sent by the will of Yggdrasill as a trial to find superior beings. Gankoomon and Bao Hackmon together manage to send Ogudomon into space, and then Ogudomon simply stops acting, whereas even the Royal Knights do not fully understand the will of Yggdrasill.

The Digital World is undergoing a great chaos, a vortex of war never seen before. The cause: the main computer had the task of maintaining order; however "Yggdrasill" suddenly vanished. Due to the lack of rules, the Digimon tried to gain power to become the "Next Ruler of the Digital World".

In the forest, far from the wars, Aegiomon was living in peace with his friends. He was born in Digital World: Iliad and originally was Jupitermon, one of the Olympos XII, but at some point he became Aegiomon and lost his memory, suddenly appearing in the Digital World ruled by a missing Yggdrasill while having to fight for his fate in the battlefield.

Gankoomon is one of the Royal Knights and Hackmon's guardian.

Yggdrasill is the of the Digital World. Some time before the beginning of the story of the game, Yggdrasill spread the Program X to eliminate unnecessary Digimon, thus optimizing the Digital World. Some time after that, it is deactivated.

After being sealed and deactivated within the Infinity Mountain for a long time, Yggdrasill reactivates on its own when it feels the danger that the aritificial lifeform called Vitium represents, and reuses the Program X in order to prevent Vitium from destroying the Digital World.

It should be noted that it's highly implied that this Yggdrasill is the same one from Digital Monster X-Evolution.

Several Yggdrasill terminals are fought leading up to the final boss of the game, the main Yggdrasill unit fused with the Mother Eater. Once Yggdrasill is freed from the Eater influence, its normal functionality is restored and it begins repairing the Digital World. Yggdrasill also appears on a Digimon Medal.

The various members of the Royal Knights mention they work for Yggdrasill.

 * Yggdrasill is named after the that connected the  in, tended by the , after which the Terminals in the NEW Digital World that Yggdrasill created are named.
 * In Digimon Fortune, there's a huge "World Tree" in the Packet Island that has a connection with the Orbital Elevator called "Noah" that connects it to the Dark Area. Although the name is the same as the avatar created by Yggdrasill that supports the Digital World, and has a similar appearance to the Tree used in Digimon Savers and Digimon Xros Wars (Manga), no relation between it and Yggdrasil is made in the game itself.
 * In Digimon Adventure:, a "Big Tree of Information" appears, similar to the "Information Tree" in Digimon Xros Wars (Manga) (which Bagramon states is Yggdrasil). Whether they're the same thing in Adventure: and Xros Wars is unconfirmed.
