If you're looking for a happy storybook ending, you won't find one here. This is a tale of depravity and sin. The jealousy of another's accomplishment. Humankind's craving for power. The avarice of wanting repute or material gain. The passionate desire to claim, to be in control. The fulfillment of pride when playing the hand of God. The indolence in ignoring the costly price of their actions. And the ultimate fury, unleashed by their own creation. Envy, Gluttony, Greed, Lust, Pride, Sloth, and Wrath. This is the story of an artificial life made legend.
||Where It All Began||
Across a vast sea, there exists an archipelago made up of five islands in total. Four are natural, while the fifth is located below the other isles, and is to be the main focal point where the major event went down. It is in fact an artificial island, a large floating structure called Aether Paradise. As its name suggests, it is run by an organization known as the Aether Foundation, who created the facility as a base for their research. From the outside, it is believed that the foundation works to aid and protect wild Pokemon who've been harmed or mistreated, and includes a Conservatory area as well as a jamming signal that prevents the capture of these rehabilitating creatures. Tours are often offered to trial-goers/Trainers.
Under that benevolent exterior, though, there once hid the darkness of a wicked conspiracy that to this day has yet to be washed clean. A private sub-level that was off-limits to tourists and regular personnel. It consisted of two laboratories. Lab A was home to secret files about Type: Null, while Lab B contained information of mysterious creatures termed as Ultra Beasts. They originate from Ultra Space, a spatial realm that links to a number of different universes and dimensions through a phenomena known as an Ultra Wormhole. The wormholes are infrequent and usually not expected for either the Ultra Beasts or the residents of the dimension it connects to. This causes the Ultra Beasts to be confused and combative as they search for a way back home. It was because of these extra-dimensional beings that Type:Null was created.
||The Project Preparation||
In order to deal with the increase in Ultra Wormholes and the angered Ultra Beasts emerging from them, a few of the higher-ups in Aether took steps in preventative measures. Since most pokeballs have difficulty recognizing the Ultra Beasts as Pokemon, a new type of pokeball needed to be invented. Building off the work of a predecessor, Branch Chief Faba engineered the Beast Ball, a capsule with a higher catch rate against the Ultra Beasts. But it wasn't enough. Not only with Alola's guardian deities, the Tapus, at times appearing to confront the extraterrestrials, or even a special UB task force of select humans who try to either safeguard or destroy the Ultra Beasts. More needed to be done, and that was when Aether made its first big mistake.
The decision was made to embark on a new development, the BK Project, to create a Pokemon capable of fighting the Ultra Beasts on an equal if not greater footing. There were to be three Type: Full model series, each meant to be an Anti-UB Fighting life-form, codenamed Beast Killer. The technology from years of experimentation were applied to their design. Blueprints showing how the cells of every known Pokemon type was used in their genetic modeling, to give them the ability to shift between types by holding a corresponding memory disc. This idea was inspired by myths researched at Canalave Library, in regards to the life plates of Arceus that allow it to also change its type. It also paid homage in the name given to its Type change program and signature Ability: The RKS System. Its transplantation, however, did not go according to plan..
Serial number 01 and serial number 02 of Type: Full were initialized, and their RKS System were activated during separate tests. Both experienced defects and underwent rejection of their programming, and shortly thereafter went completely berserk before they were subdued. The third lasted longer, and went through additional trial-and-error, but eventually it too rejected and rampaged, killing several who were on scene at the time. Once restrained like the two before, each was given a limiter helmet to lessen the effects of the RKS System, and ordered to be put into permanent cryogenic stasis. The Beast-Killer project was deemed a failure, and their names were changed from Type: Full to Type: Null.
The three models were supposed to be frozen for all eternity. But as fate would have it, a young boy named Gladion found out about the terminated project. He was able to free serial number 01 from its containment, and took it with him when leaving from Aether Paradise. Sources next lead to the belief that he acquired serial number 02, in order to pass it on to a Trainer befitting, though the second Type: Null could very well be loose in the wilderness beyond Alolan shores. As for the final chimera, serial number 03, there was no retrieval. He was kept cryogenically frozen, and for good reason. His was a special case. The brutality displayed when he attacked the scientists on standby was so savage, that his cell was placed in a deeper unit of cold storage.
It was later discovered that a member of Team Skull was tasked with "stealing" all of this particular chimera's memory discs, and scattering them throughout the regions. In the hopes that the beast-killer would never again reclaim his full arsenal of type discs. It was almost as if they feared their creation somehow breaking out, which he did when the facility went through a temporary power outage during an attack by a Necrozma. The Type: Null's first act had been to immediately smash the control mask that'd been fitted over his head, before escaping the floating structure and swimming to the island of Akala. The synthetic's whereabouts are currently unknown, but cold logic dictates that he is out there, not only hunting down the Ultra Beasts he was programmed to destroy, but to also recover the missing memories for the unstable RKS System.
