Phobia used to be a beautiful angel with pure white feathers, who was brought to be to guard the dying on their last journey to the afterlife, taking away their pain and fear in their last moments. He successfully kept this up for thousands of years, but his work speed eventually started becoming sluggish, overwhelmed by the sheer amount of people being killed in the apocalypse.

He could do nothing but watch as his workload turned into a sea of decaying corpses. Their screams and begs for mercy ate away at his brain and he eventually got engulfed in it, their death and anguish latching onto his body in the form of a disease.
