When drawing something I have always taken into account the main characters but rarely the main enemies, so here I start XD

Its origin is completely unknown, but it is known that the biomechanical entity known as Allera is hundreds of thousands of years old and whenever an intelligent species seeks to interact with it in a diplomatic way this and its forces disappear, Allera is a mysterious organism that always seeks the creation by its own hand of life forms that are superior and better for what she calls "the universal balance" using primitive life forms from other planets, being her most known creation, and probably the most perfect and independent, the Zoosapiens generation 1.

She collected a large number of specimens of mammal, reptile, bird and amphibian species of the predator class on Earth stealthily with the help of her machines between 1960 and 1982, sending them to her artificial planet of unknown name, where after analyzing all the main physical, behavioral and intellectual characteristics of the collected animals, she proceeded to experiment with them and after many failed attempts and evolutionary acceleration procedures with the 295 isotope and cybernetic augmentations, she succeeded in creating new species of animals.
Successfully creating new species of intelligent life forms capable of reasoning and learning like a human being and even with greater memory and speed and preserving the superior capabilities they had in their primitive form, the Zoosapiens generation 1 were his greatest creation up to that moment and the one that was most tested in his following operations to turn them into the most adaptable and effective super soldiers.

In spite of their success, the fact of having endowed these anthropomorphic animals with intelligence made them, in spite of doing unconditionally what Allera programmed them to do, begin to realize the terrible things she had done to them as well as the treatment they were given as if they were only replaceable robots if something happened to them or they suffered a lot of pain, with which it was inevitable that they would reveal themselves and with all the knowledge they had been given, both of the human civilization and of the technology used by Allera, they were able to free themselves from her control apparently by eliminating her and escaping back to Earth with the portals that brought them, since with the apparent death of their Creator she had destabilized the environment of the planet making it dangerous and uninhabitable, keeping themselves hidden from humans since their arrival in 1984 until their inevitable more direct encounters during the conflicts against Darkmoon.

It was during this period that humanity showed great curiosity to continue Allera's idea of creating their own Zoosapiens and modifying the original ones in projects such as generation 2 and its taxonomic variants, the taurs with Garlesh DNA and the Terragen, causing wars between both species that could come to an end with the dismantling of Darkmoon and the creation of the Treaty of the United Species by the UN and CASE, finally recognizing the existence of a species of intelligent animals with which humanity could coexist peacefully in their society.

However, Allera had only been temporarily dormant for 100 years and upon becoming aware of the independent progress of their creation, as well as the improvements and alterations that such an "unworthy" species as humans had made to them over time and were now trying to live with them as if they had done nothing, She mobilized her forces to attack Earth and modify other species from other worlds for the creation of new species that would help her with her goal of punishing humanity and regaining control of her children, who she believed should be free from the influence of other species and remain her greatest servants, seeing herself as their God, and later demonstrating to herself that the true objective of her creation was to create an adaptable and lethal armada capable of facing the imminent invasion of the Kor'vlann.
