Psychopathic & Sadistic, High Pain Tolerance, Narcissistic & Vain, Unpredictable & Chaotic, Jeff, is a male charater, who's 13 to 17 years old, mostly being called Jeff, or woods. His most defining visual attribute is a permanent, grotesque grin carved directly into his cheeks from ear to ear. Jeff deliberately burned off his own eyelids so that he would never have to close his eyes and could look at his face forever. This gives him a perpetual, unblinking stare. His skin is an unnatural, ghostly, stark-white color. He has long, unkempt black hair that was singed and darkened during the fire. He is almost always depicted wearing a plain white hooded sweatshirt and black skinny jeans. His white hoodie is typically splattered and stained with the fresh and dried blood of his victims.

Sadistic Mind-Breaker, Highly Intelligent & Deceptive, Arrogant & Controlling, Unpredictable Virus, He looks like a dark, ghostly version of Link, wearing a faded green tunic, matching pointed hat, and dark boots. His most iconic feature is his eyes—they have pitch-black sclera (whites) with glowing blood-red pupils, and a dark fluid constantly streams down his cheeks. He is short with messy blonde hair and pointed elf ears, but his skin is an unnatural, pale grey that frequently warps with digital glitches. He is always drawn popping out of TV screens, laptops, and phones, manipulating code with his hands. He loves physically holding a game controller, using his tech powers to torture whoever is playing on the other side. Fan animations usually show him hovering above the ground, glitching through solid walls, and turning completely invisible.

Bipolar & Unpredictable, Physically Numb, Haunted & Delusional, Involuntary Twitching, Chaotic Slasher. Toby's a male charater, who's 17 to 19 years old, mostly being called as Toby. He is always drawn in his signature light grey hoodie with dark brown stripes on the sleeves, worn over a blue hood, paired with dark jeans and black gloves. His most recognizable gear is a pair of round, yellow-or-orange tinted goggles and a striped black-and-grey mouth guard with a vent-like design. In art where his mask is removed, he has a permanent chunk of flesh missing from his left cheek (a result of severe facial twitching and self-injury), completely exposing his teeth and gums underneath. He is rarely drawn without his two favorite weapons—dual hatchets strapped to a customized magnetic weapon belt around his waist.

Silent & Stealthy Predator, The "Mansion Doctor", Animalistic Hunger (cannibal), Organ Harvesting (mostly kidneys), Lurking in Shadows, The Quiet Outsider. A male charater, who's 17 to 19 years old. Mostly being called Jack, or EJ. His most defining feature is an expressionless, deep-blue mask with absolutely no nose or mouth—only two wide, completely hollow eye sockets. Dark black fluid (often interpreted as a mix of hot tar and demonic blood) is always drawn streaming or dripping heavily down his mask from the empty sockets. He wears a plain black hoodie with the hood pulled up high, dark jeans, and occasionally surgical gloves. (Unmasked): When artists draw him without the mask, he has sharp, razor-like teeth, inhuman grey skin, messy brown hair, and sharp, retractable claws.

Exhausted & Stressed, Cold and Ruthless, Reluctant Leader, Dominational. A male charater, who's mid-20s and mostly being called Masky, or Tim. His main feature is a stark-white, theater-style mask with black, somewhat feminine features painted on it, including heavily shaded, hollow eye sockets and dark lips. He is always drawn in his signature mustard-yellow or tan Carhartt-style jacket with a dark brown collar, worn over a dark shirt or hoodie. When his mask is off or pushed up, artists heavily emphasize his thick, iconic sideburns, messy dark brown hair, and slightly stocky, realistic build. While he occasionally uses a handgun, fanart almost universally arms him with a heavy iron crowbar.

The Silent Observer, Loyal Friend, Deceptively Cruel, Sneaking and Infiltration. A male charater, mid-20s. Mostly being called as hoddie, but Masky calls him Brian. His most legendary feature is an oversized, bright mustard-yellow or orange-yellow hooded sweatshirt with the hood pulled tightly over his face. His mask is actually a black cloth or ski mask pulled tight, featuring a hand-stitched, frowning sad face sewn on with thick red or yellow thread. When unmasked, artists typically draw him as a handsome, calm guy with short brown hair, gentle eyes, and a stubble beard—a stark contrast to his creepy mask.

Obsessive & Manic, Energetic, Fangirl Stalking (Jeff). A female charater, mostly called Nina 15-17 year old. Wearing a vivid pink hooded sweatshirt, a black pleated skirt, and tall thigh-high striped socks.
