Slime Girl
The Xenopox Virus was created at MedUSA, a laboratory, in Oregon, though as a company, its facilities are spread across the globe. The base of the chemical concoction was the actual poison of the snake god, Ophion. In ancient times, anyone that Ophion bit would become snake people, reptilians. They would bite others, and the further away from Ophion’s original victim, the less human traits the victims would keep and the more of a reptile they would appear.
The original poison used had come from an ancient unearthed relic. Using the poison as a starting point, MedUSA began testing and tweaking the properties. The original idea of the board of directors and several of the scientists was to find a way to resurrect the snake god himself, perhaps by cloning. However, all attempts using the poison, failed. They then tested the poison on animals and people. By studying the effects on a microscopic level, they grew to understand the properties of the substance better. It caused mutations of varying types and degrees based on mixing with the DNA of different organisms. After the lab was destroyed by Siri Solen, the mutants that managed to escape sought refuge in the nearby sewer system.
The slimes that patrol the Portland sewers occasionally find and consume those that enter the area. Usually the homeless or city workers, the slime covers their bodies both consuming and transforming the flesh into more slime. Though they retain nothing of their former selves, these slime people ooze about the same sewers with the intent of transferring the goo to new victims. When the Night Stalker, Absinthe Van Gothen, came to the sewers to find Molly McCoy, she slew all the slime people that she came across.
