The Dark Latex Beast originates from the unintended consequences of Project: Geneticus Immunitas, spearheaded by Dr. Richard Kelly (Dr. K) within the Thunder Science Company. Designed as a potential solution to combat the Pale Virus, the Black Latex substance inadvertently gave rise to these menacing entities, further complicating the dire situation within the facility. Formerly humans who were forced to comply to the experiments, they are a shell of what they once were. Their memories and what made them them, no longer there. Instead replaced with primal instinct.

The Dark Latex Beast possesses a tar-like, viscous exterior that appears almost fluidic yet solid, providing it with an eerie, shadowy presence. These entities exhibit humanoid canine features, often appearing as menacing amalgamations reminiscent of wolves or hounds. Their form is characterized by a dark, glistening surface that absorbs light, making them appear almost ethereal in dimly lit environments Adorned with a white mask-like covering over its face, the Dark Latex Beast possesses piercing white eyes that contrast starkly against its dark visage. Its physique exudes strength, agility, and an aura of malevolence, making it a formidable entity to behold.

Transformation Process:

Upon contact with a host, the Dark Latex Beast initiates a chilling process known as "Geneticus Parasitum." This transformative dance results in the absorption and restructuring of the host's cellular structure, giving rise to new instances of the Dark Latex species. The process erases the host's former identity, leaving behind a haunting semblance of their former self trapped within the confines of the beastly form.
