Prologue: plumber official intro and the Inpuratus
Plumber authors note
In recent years, the hunter Khyber has sought to kill Ben Tennyson using the Nemetrix. This device was made by the mad Dr. Psychobos, a knock off variant of the Omnitrix that contains the predators of the various DNA samples used by Ben Tennyson, a seemingly perfect counter. While the Nemetrix is currently in Plumber custody, it has inspired many copycats.
Only the absolute smartest have managed to recreate the Nemetrix, and even then they are limited to a few different forms, with a maximum of ten. While this limit does exist in the original, that was due to Khyber's code of honor as a hunter rather than any limits on the technology itself. However, most of the criminal elements of the galaxy have made do with control collars designed to mimic the Nemetrix in appearance. This file is designed to allow Plumbers to learn about the various predators that inhabit the galaxy, so that if they are encountered the Plumbers can survive and hopeful defeat them.
Of the Inpuratus
Interestingly, while humanoid evolution seems to be the predominant line of life, humanity seems to be the only species without a natural predator. Most, if not all, species encountered by the Plumbers have at least one creature perfectly designed to hunt them down and kill them. For most of the Plumbers history this was believed to be because of humanity's lack of any natural powers. As such, no predator could arise, for there was no power to counter.
However, recent data taken from a destroyed Vilgax ship revealed a dark secret that sheds much light on the existence of most of the predators that exist in this universe. Many scientists and scholars have noted that these predators seem perfectly suited to counter their preys powers, suggesting something more than simple evolution.
But none of those scholars realized just how correct they were. There once existed a race known as the Inpuratus, a truly disgusting race that resembled human sized maggots with twin clasping arms and the face of a lamprey. Much like the old Highbreed regime, the Inpuratus sought to purge all life forms other than themselves. Unlike the Highbreed, there hate of all others was not because they were dying out, indeed far from it, but instead it was completely personal. Also unlike the Highbreed who used only one artificially created creature, the Xenocites and the resulting DNAliens, the Inpuratus decided to use many.
Using their level 20 technology, they studied the many races and made predators to perfectly counter them. In addition, they created artificial intelligences who commanded grand gene forges that still bedevil the universe long after their masters utter annihilation. With the creation of these predators, they then break the laws of time and insert these predators into the distant past. While this did not destroy most races, the Inpuratus planned to lead a vast crusade using the many predators they have made.
In addition, they saw the Omnitrix project as their greatest foe. Indeed, once Azmuth and the caretakers of Primus and the other Omnitrix backups knew what to look for they purged the links of the various Inpuratus AI's, but always more are found.
However, the Inpuratus made a fatal mistake when they created Predators for the Chimera Sui Generis, the race of the infamous galactic warlord Vilgax. For all his faults, Vilgax cares for his people. Such is his love for his race that he willingly put aside his hatred for Ben Tennyson, his massive pride, and his desire for the Omnitrix to ask for his help against the ectonurite Zs'Skayr. Upon learning of the Inpuratus through means unknown he led a massive attack upon the world of the Inpuratus, destroying the entire race.
However, despite the Plumbers, the Galvan's and Vilgax's empire all hunting for the gene forges of the Inpuratus, they still exist and churn out predators for a hateful race that no longer live.
