Isaac 'Zack' Foster was brought to an abandoned building as part of an experiment by Abraham Gray. He needs an ally to help him escape the building. He is a lean, tall young man with short black hair and wears bandages all over his body to cover up burns. His eyes are mismatched, one being amber and the other being entirely black. When in a frenzy, his amber eye glows red. He wears a zip-up hoodie stained with blood, red jeans and black combat boots. He usually wears a scythe.
