D-Reaper

The D-Reaper, also known as the "True Enemy", is a digital lifeform which appears as the central antagonist in Digimon Tamers. It is referred to as "Matador" () in Brazilian Digimon Tamers materials.
Unlike most inhabitants of the in Tamers, it is not a Digimon; while Digimon descend from the virtual wildlife system created by the "Monster Makers", the D-Reaper was allegedly created in the late 1970s by the , as an antiviral program for the "Creeper" virus. It is possible it is only a descendant of this program, though, which was then known as the "Reaper", and other theories place its origin with the security program used by the in the 1980s for their "" project. The D-Reaper's only purpose is to purge the Digital World once the number of lifeforms within it surpasses a certain number, and it pursues this goal with deadly efficiency. It is in hibernation deep beneath the Digital World as Tamers begins, but it is reawakened and begins to ravage the Digital and Real Worlds by the end of it. Though it began in an extremely primitive state, it is thought that its ability to become powerful enough to overcome the Digital World was due to its hibernation being so far beneath the Digital World that it actually connected with another dimension.Digimontamers Resources: D-Reaper Report
Despite being a fictional character, the D-Reaper's backstory is linked with real-life events and organizations, such as the outbreak of the , one of the first to spread significantly, and , a real, highly secretive worldwide intelligence-gathering network.
==Design and conception==
When designing the D-Reaper, the head writer Chiaki J. Konaka was looking for an enemy for the show's final story arc that was "an entity that is neither Digimon nor human". In order to create such an entity, he brought together the three foremost designers that worked on Digimon Tamers.
There was Mr. Kenji Watanabe, originator of the Digimon virtual pet and game. There was Mr. Katsuyoshi Nakatsuru, designer of the human characters. There was Mr. Shinji Aramaki, CG Designer as well as a mechanic and character designer. I believed that if these three were to use their imagination and construct the D-Reaper in competition with each other, an enemy character unlike any ever seen before would be born.
Each of the various forms of the D-Reaper was created by one of these artists, except for "Reaper" who was worked on by both Watanabe and Nakatsuru. The general design aesthetic of the D-Reaper was that of a "Digital creature", exemplified in such details as the jigsaw-like fringes of the Agents, and the optic fiber/telephone wire construction of the Reaper and Mother D-Reaper. Konaka remarked that he was especially fascinated by details like the wings on ADR-02.Digimontamers Resources: ADR Variations Aramaki was also responsible for the design of the D-Reaper Zone as it appears on Earth.Design Works bv Shinji Aramaki
==Story==
===Digimon Tamers===
The Reaper program was created in the late 1970s, allegedly by the United States Department of Defense, before Digimon and even the DigiGnomes, which appeared in the early 1980s. Though this is only set 30 years in the past of Digimon Tamers, in the fast-growing Digital World it is comparable to the period (542-488 ). It was designed so that whenever the number of digital lifeforms surpassed a set amount, it would delete them to return the Digital World back to a state of nothingness, in order to prevent the Digital World from being overloaded. However, when it was written, the Digital World had a very small size, and while the network has grown exponentially, the D-Reaper's threshold is still based on that early, tiny figure. With nothing to do at the time, the D-Reaper program went dormant and remained deep within the recesses of the Net.
At about this time, the "Creeper" virus infected , the network belonging to the Department of Defense. It was deleted by the "Reaper" program, which was allegedly created for only this purpose.Digimontamers Resources: Chronicle of the Digital World and Virtual Creatures
In 1980, the Artificial Life research project "" began operations. However, the Reaper program caused mass genocide of Tierra's virtual lifeforms whenever they multiplied beyond a certain amount of memory. Throughout the 1980s, the system known as "ECHELON" began operations under the leadership of the , which built communications bases in various nations across the globe. It is thought that the self-defense program used by ECHELON was a forerunner of the D-Reaper, or the program itself.
By the 2000s, the network had expanded exponentially. This created a huge influx of data into the Digital World, which the Digimon used to "digivolve" and change. Though the system was large enough to handle this load, the sensed that it could reawaken the D-Reaper, and with the help of the DigiGnomes, he transformed the "Catalyst" program into the form of a Digimon, . Though this greatly slowed the growth and Digivolution of Digimon, it was not enough to stave off the D-Reaper, which soon reactivated. At the time, though, it was still in an extremely primitive state, and the Sovereigns attempted to find solutions before the problem grew. Despite this, the D-Reaper began to emerge in the form of a fluid-like field that destroyed anything it touched. 
The D-Reaper kidnapped Jeri in order to learn more about humans, and its first Agent in her form to disguise this act and to lead it to the Real World. The primary aspect of the D-Reaper follows the Tamers to the Real World using the Hypnos system and immediately began to spread it's field over Shinjuku. The D-Reaper also begins to produce Agents, mobile forms that were not seen in the Digital World, potentially because it was harder to 'delete' the physical matter of the real world. In an excursion inside the D-Reaper Field, Takato discovers that Jeri has been replaced by a D-Reaper infiltrator. The tamers discover the Kernel Sphere , the nucleus of the D-Reaper, hidden high between the two towers of the Hypnos building, with Jeri sealed inside. Here, Jeri's grief was provoked to serve as a source of energy for the D-Reaper much like Tamers serve for their partners, but Beelzmon's attack on the sphere provokes the evolution of defensive measures. Only Biomerged and Mega-Level (like Beelzemon) Digimon were able to fight it on even terms, but the D-Reapers development of its Mother form marked the point it began to outstrip the tamers ability. Eventually, the D-Reaper began a global attack on Earth's electronic systems, manifesting its field in multiple cities, while most of the Digital World was destroyed. The D-Reaper, using the Jeri-type as it's mouthpiece, deemed that both races were inherently destructive and therefore unsuitable to live. The Tamers invade it's using a special red card to allow their mega evolutions to be maintained within the field, and attempt to deal with the D-Reaper by forcing it through a rift into the digital world that would, as a byproduct, revert it's evolution until it was rendered back into a harmless and primitive program. However, the Mother-type summons the Cable Reaper through the rift, a merger of the D-Reapers agents that represented a drastic evolutionary leap that, if allowed to assimilate with the Mother-type, would allow it to complete it's genocidal objectives. However, through the combined effort of everyone in Operation: Doodlebug, Jeri was rescued by Gallantmon from the Kernel, depriving the D-Reaper of its source of power, and MegaGargomon reversed the pull of the wormhole the Cable Reaper came through so it could be dragged back down by the , exceeding the speed-of-light, causing the D-Reaper to be pulled through and finally devolve into an extremely primitive and harmless program once more.

The D-Reaper is represented in the Chaos Wasteland stage, in which it forms the backdrop of the area. The flies around in the background of the area.
===Digimon Masters===
The D-Reaper invades Shinjuku and its Agents can be fought.
==Forms==
The D-Reaper encountered by the Digimon Tamers is considerably different from the simple computer program it originates from. In the Digital World, the D-Reaper appears in the form of a large, red chaotic field with a gelatinous appearance.. Any data contacting the D-Reaper is immediately absorbed and disintegrated. Despite this, Digimon are able to fight the D-Reaper to some degree
In the Real World, the D-Reaper still appears as a crimson mass, termed the D-Reapers "Zone". However, it can not absorb objects in the real world as quickly as they are not made of data. It works slower and adapts to the situation by studying the real world, resulting in its mass evolution and production of various Agents, all of whom are tethered to the D-Reaper Zone with a red cable. Severing this cable completely destroys minor Agents and severely weakens more advanced forms. 
Furthermore, conventional weapons such as missiles have no detectable effect on the D-Reaper, much like with Digimon.
==Agents==
To accomplish its goals, the D-Reaper utilizes a variety of forms known as "ADR's", or "Agents of the D-Reaper". Unlike humans and Digimon, ADR's are not individuals, and they all act according to the single consciousness of the D-Reaper. When they operate outside of the D-Reaper Zone, they are connected to it by red wires, similar in function to umbilical cords. When these cords are severed, the Agent becomes much weaker and easier to defeat, and weaker Agents will dissipate completely. Once the D-Reaper creates a new type of ADR, it will continue to use it until it is no longer useful and efficient. The various ADR's are named by the order they are created in, though they also possess codenames based on their appearance and function. The D-Reaper eventually absorbs its Agents as a last line of defense against it's attackers, becoming the "" and "".
===ADR-01: Jeri Type===
The ADR-01: Jeri Type is a Spy Agent whose form is based on Jeri Katou from when she was most grieved. It was created in order to analyze human thought, and is the only Agent who can operate comfortably outside of the D-Reaper Zone detached from the umbilical cords. It starts out identical in form to Jeri, but can evolve into several variations. It was designed by Katsuyoshi Nakatsuru.
This Agent is created for the purpose of espionage, posing as Jeri Katou while the real one is in the Kernel Sphere. The infection begins when a small portion of the D-Reaper infects Jeri not long after first appears. It stays dormant while in the Digital World, though it leads to Jeri's thoughts becoming more depressed and fully manifests in her personality once back in the Human World. Takato Matsuki and find this Agent masquerading as Jeri in the D-Reaper during one of their assaults on the program, where it acts as the D-Reaper's mouthpiece. It wages a mental war against Takato by displaying the information it took from Jeri's memories to hurt him emotionally and keep him off balance. When Takato is sufficiently weakened, the Agent reveals its true, monstrous form and begins to attack. It is only warded off by 's power. Eventually, when Jeri regains her will to live, it personally attacks Jeri to absorb her energy, but it itself is reabsorbed by the D-Reaper in the same manner.
The Jeri-type serves as the Mother D-Reaper's first line of personal defense, being made of cables and looking almost like Jeri's face, apart from its distorted eyes and overly large mouth. This avatar is able to incapacitate , but he manages to transform into and destroy the face with his javelin.
The Jeri-Type once again emerges as the last obstacle between the Tamers and the Kernel Sphere. it proves to be quite a challenge for Gallantmon Crimson Mode, destroying his weapons and slamming him into the Mother D-Reaper itself. All the while, the Jeri-Type taunts the hero, saying that humans and Digimon are naturally destructive and do not deserve to exist. However, Takato and Guilmon refuse to give up, calling upon their full strength to break free and declaring they do deserve to exist, but the D-Reaper doesn't. With that, they deliver a devastating punch to the Agent's chest, finally destroying her.
In Digimon Rumble Arena 2, the Jeri-Type appears in the background of the Chaos Wasteland stage.

==Similar concepts==
Chiaki J. Konaka, the head writer for Digimon Tamers, is also one of the writers for the , and the D-Reaper is primarily based on the ancient horrors of 's work, sleeping until they wake and destroy the world. It also draws from the Rei/ fusion in Neon Genesis Evangelion; like the Rei/Lilith fusion, it seeks to absorb the world in order to eradicate humanity's illogical emotions and negative feelings. Furthermore, the Mother D-Reaper's mask resembles that of Lilith, and at one point it even materializes a giant replica of Jeri's head to attack while the real Jeri is held inside of it, similar to how the Rei/Lilith fusion's mask falls off to reveal Rei's face.
