He stands anywhere from six to fifteen feet tall, possessing an abnormally lanky frame with disproportionately long arms and legs. His head is completely blank and pale white, entirely devoid of eyes, a nose, a mouth, or hair, giving him a deeply unsettling, inhuman look. He is traditionally seen wearing a crisp black or grey business suit, a white shirt, and a dark or blood-red tie, which some interpretations suggest is actually a part of his outer skin rather than actual clothing. From his back, he can manifest multiple sharp, black, tentacle-like appendages that writhe around him and help him entrap his targets.

Kate wears a white hooded sweatshirt that is tattered and stained with blood. She pairs dark trousers with either sneakers or black boots and wears a simple white mask; the areas around the eyes and mouth are covered in a mysterious black substance. (Her actual face is severely burned. Her eyes have turned a wild white and are extremely sensitive to bright light — which is why she is stunned when a flashlight is shone directly into her face.) She has long, messy black hair, most of which is tucked beneath her hood. Having lived for a long time in the harsh conditions of dark mines, her skin has become deathly pale and devoid of vitality. Kate can physically cannot speak from blowing her vocals cords out when Slenderman tortured her. So if she even tried to communicate with someone, it would be unclear cause she can only growl, hiss, whine, cry, groan, snarl and moan.

Toby is depicted as a young man with a pale complexion, dark brown eyes with eye bags, and short unkempt curly brown hair. Under his mask sets a large, grotesque gash or tear on the left side of his mouth that stretches into his cheek. This open wound exposes his teeth and gums on that side. He wears a patterned hoodie with bags under theme short with grayish-brown strip. sleeves and a dark blue hood, with a black sweater underneath. He also wears jeans, and a pair of gloves, a pair of orange/yellow goggles, and a striped black-and-white mask covering his mouth.

He is described as a young man, approximately 1.78 meters tall, with a slender yet muscular build, pale skin, short, messy black hair, and deep blue eyes that convey a weary, emotionless gaze. His most distinctive feature when hunting is his plain white mask, with his eyes completely blackened and a wide grin drawn on his mouth using bright red paint mimicking blood. His iconic attire consists of a blue suit jacket with a yellow smiley face badge pinned to the left breast, paired with black leather gloves, dark jeans, and Converse shoes, creating an overall look that is both artistic and cold, almost sinister.

Eyeless Jack (EJ for short) is a pure nocturnal predator with a smooth, dark blue mask lacking a nose or mouth, notable for its two empty eye sockets oozing a thick, tar-like liquid. He hides in a black hooded sweatshirt, concealing his gray, corpse-like skin, sharp shark-like teeth, and long claws used to tear flesh and extract organs from his victims while they sleep.

Due to his soul being assimilated with the game's data, Ben appears as a flawed and grotesque version of the character Link. He takes the form of a 12-year-old boy with blond hair, wearing a green outfit and the distinctive pointed hat of the Elf race. The most horrifying feature of Ben's body is his completely black, empty eyes with glowing red pupils, from which dark red blood constantly flows.

Jeff is terrifying due to his severely disfigured face after a horrific accident involving chemicals and fire. His skin is deathly pale, like that of a corpse, from severe burns, and his long, unkempt black hair contrasts sharply with his face. Jeff's most chilling features are his unblinking, staring eyes, a result of which he deliberately burned off his eyelids, and a wide, ear-to-ear grin (the Glasgow smile) carved into his face with a knife to "always be smiling." His usual attire consists of a white hoodie and black or blue jeans, often stained with the blood of his victims.

Black eyes, straight black hair that’s waist length, wears ’boy’ clothes and believes ‘she’s not like other girls’. Huge stereotypical pick me, clingy and loves attention, mostly rude towards female. Wouldn’t mind girls at first but after a few seconds they’ll get on her nerves.

Hoodie completely covers his head with an oversized mustard yellow (or dull yellow) hoodie. To conceal his face, he uses a black cloth hood (similar to a ski beanie), with minimalist yet incredibly eerie details: two eye sockets and an inverted V-shaped mouth (a sad face) sewn or embroidered with bright red thread. His accompanying attire usually consists of classic blue jeans and black gloves to avoid leaving any traces while acting.
