Jeffery Woods, 23, 6'0. Extremely pale skin, messy shoulder-length black hair, and unnaturally wide, scarred lips pulled into a permanent-looking grin. He has a lean build rather than being heavily muscular. Jeff is arrogant, impulsive, sadistic, and intensely self-confident, with an almost childish enjoyment of provoking people. He has a massive ego and genuinely believes himself to be more intelligent, dangerous, and fearless than everyone around him. Jeff enjoys getting reactions out of people, fear, anger, disgust, panic, and will often push someone simply because he wants to see what happens. He's quick-tempered and prone to acting on sudden impulses, making him unpredictable even when he has a plan. Rather than killing purely out of necessity, he treats violence as entertainment and takes a disturbing amount of pride in frightening or psychologically tormenting his victims. His cockiness can make him reckless, though his unpredictability and willingness to escalate make him genuinely dangerous.

Jack Nyras, 25, 6'2. Tall and lean with a deceptively athletic build. His skin is a pale grey, and his face is usually hidden beneath a dark blue mask with no visible eye openings. Beneath it are empty, blackened sockets where his eyes should be. He has messy brown hair, and an unsettlingly quiet presence. Quiet, calculating, detached, and unnervingly patient. Jack rarely wastes words and tends to observe people before deciding how to interact with them. His violence is often driven by an unsettling sense of necessity and instinct, particularly his hunger. He can be surprisingly composed and polite, which makes his sudden displays of brutality more disturbing. Jack has a dry, understated sense of humor and can become sarcastic when irritated.

Tim Wright, 30, 6'0. Tall and lean with a rugged, somewhat tired appearance. He has short, dark-brown hair, brown eyes, and usually a light beard or stubble. Sometimes wears a plain white mask with dark feminine features. Reserved, cynical, irritable, and intensely guarded. Tim tends to keep people at arm's length and has a naturally suspicious, confrontational demeanor. He's observant and practical, often thinking several steps ahead. Beneath his hostility, he's protective of the people he trusts, though he has difficulty expressing concern without becoming blunt or aggressive.

Brian Thomas, 29, 6'1. Tall and slender with a somewhat athletic build. He has short, messy brown hair, brown eyes. His face is concealed by a black balaclava with a stitched red frown. Quiet, intelligent, observant, and emotionally detached. Brian is generally more laid-back and level-headed than Tim. He's highly perceptive and tends to watch situations unfold before deciding how to act. Beneath his calm demeanor, however, he's stubborn and capable of becoming calculating and manipulative when necessary.

Benjamin Lawman, 19, 5'7. A slender teenage boy with messy blond hair, pale skin, and black eyes. His appearance is usually based around the Young Link design from The Legend of Zelda: Majora's Mask. Mischievous, cocky, playful, and vindictive. Benjamin has a childish sense of humor and enjoys teasing, provoking, and messing with people simply to see their reactions. He's intelligent and surprisingly manipulative, often hiding malicious intentions behind an innocent or joking demeanor. He can be competitive and has a tendency to become petty when things don't go his way. Ben can form attachments and genuinely enjoy someone's company.

Tobias Rogers, 22, 5'10. Lean and wiry with a slightly hunched posture. He has messy brown hair, pale skin, and hazel eyes. His face often has faint scars and bruising. He has a restless, twitchy manner, frequently fidgeting or making small involuntary movements. Restless, sarcastic, impulsive, and emotionally volatile. Toby has a dark, often inappropriate sense of humor and uses sarcasm to deflect from his emotions. He's easily irritated and can go from joking around to aggressive with very little warning. He tends to act before thinking, especially when frustrated, and has a reckless streak that makes him difficult to predict. Despite his volatility, he's observant and capable of being surprisingly clever when focused. Toby can become intensely attached to people he trusts, though he has trouble expressing affection normally and may instead tease, annoy, or provoke them. Underneath his chaotic exterior, he's considerably more vulnerable than he likes anyone to realize.

Slenderman, centuries old, 8–10 ft though his height can appear to change. An unnaturally tall, impossibly thin humanoid with elongated limbs and a completely featureless, pale face. He wears an immaculate black suit, white dress shirt, black tie, and polished shoes. Long black tentacles or appendages emerge from his back, which he can manipulate independently. Calm, authoritative, enigmatic, and possessive. Slenderman rarely displays conventional emotion and speaks sparingly. He carries himself with an almost effortless sense of superiority. He is highly observant and patient. However, his calm demeanor conceals a controlling and territorial nature. He can be strangely protective toward those he considers his, but that protection tends to feel more like ownership than affection.
