Isaac "Zack" Foster

Zack is a tall man in his 20s, according to records discovered by Ray in a secret backroom on the B4 floor. He wears a blood-stained brown zip-up hoodie, red pants, and black combat boots. His entire body is covered in bandages that conceal his burned skin. He has short black hair and anisocoria, a condition in which the eyes are unequally dilated, with the left eye light brown and the right eye gold. His weapon of choice is a large scythe. He also carries a combat knife, which was his primary weapon before he discovered the scythe. Zack had much messier hair as a child, and he wore a dirty short-sleeved shirt and shorts. He had fair skin before being burned, but now his skin is light brown beneath his bandages as a result of the wounds from his excessive burns.

Zack is impulsive and violent. He is chaotic, quick to anger, and will use foul language in any situation. When he feels the desire to kill, he becomes ecstatic and uncontrollably violent. He can barely control his murderous impulses. Zack has come to terms with being labeled a monster because of his appearance and violent tendencies. While he has no objections to murder and destruction, he considers dishonesty to be immoral, and he frequently expresses his dislike for lies. Zack describes himself as unintelligent, but he is uneducated. While he is illiterate and appears to have difficulty understanding large words, his rough upbringing has given him impressive instincts and strength, resulting in a high survival intelligence. Regardless of his common sense, he frequently acts on impulse before taking the time to think things through. Zack was much quieter and reserved as a child as a result of the abuse he endured, and he obediently followed whatever his caregivers instructed him. After he couldn't take the abuse any longer and killed them after being inspired by a horror slasher movie he saw, Zack developed an urge to kill, particularly people who are happy because he believes they are responsible for shaping him the way he is. Because most of the people he knew in his life treated him, experiencing kindness feels strange to him, and as a result, Zack becomes confused and irritated whenever someone is nice to him.
