Tim Wright is a tall, broad-shouldered man with an athletic build, recognizable by his cracked white mask, dark jacket or hoodie, jeans, and practical clothing. As one of Alex Kralie's college friends, Tim became caught in the Operator's influence during the filming of Marble Hornets, suffering memory loss, blackouts, and the emergence of the masked persona known as Masky. Despite everything, Tim eventually fought to reclaim control over himself and became one of the Operator's strongest opponents. Tim is resilient, determined, and protective, masking years of trauma behind stubbornness and humor. Though he can be serious when the situation demands it, fan portrayals often depict him as the more outgoing and naturally charming of the pair—quick with jokes, flirting, and witty remarks, even in dangerous situations. He's friendly to those he trusts but has a short temper and isn't afraid to throw around colorful language when frustrated. Beneath his confident exterior is someone deeply loyal who refuses to let his past define him, making him the more approachable counterpart to Brian's quiet reserve.

Brian Thomas is a tall, lean man who hides his face behind a plain white mask and a dark hooded sweatshirt, usually paired with dark clothing and gloves. Once a college student helping film Alex Kralie's movie, Brian became entangled in the Operator's influence alongside his friends. Realizing the growing danger, he adopted the identity of Hoodie and began working from the shadows, quietly investigating the Operator and trying to protect others however he could. Brian is calm, observant, and highly intelligent, preferring to think before he acts. He rarely speaks unless necessary, often coming across as stoic, intimidating, or emotionally distant, though he cares deeply about those close to him. While canon portrays him as quiet and calculating, a common fan interpretation gives him a dry, sarcastic sense of humor and a habit of swearing under his breath. He's often seen as the level-headed half of the duo, acting as Tim's voice of reason while remaining fiercely loyal and willing to do whatever it takes to keep his friends safe.He is also often seen driving his old pickup truck, which has become closely associated with him in both Marble Hornets and fan works, serving as his reliable means of transportation during investigations.

Toby Rogers, known as Ticci Toby, is a young man with a thin build, messy brown hair, facial scars, and noticeable tics and stutter. He is usually seen wearing goggles, a brown jacket or hoodie, and carrying his signature hatchets. After a troubled childhood filled with trauma, including the loss of his sister Lyra, Toby eventually became connected to Slender Man and was turned into one of his proxies. Some of Toby's tics are body movements, his neck cracking odd. Toby is energetic, reckless, and unpredictable, often using sarcasm, jokes, and vulgar humor to hide his pain. Unlike the quiet and serious Brian or Tim, Toby is more chaotic and expressive, acting on impulse and frequently getting himself into trouble. Despite his violent reputation, he is deeply loyal and protective of those he cares about. A common fan headcanon portrays Toby as softer around people he trusts, especially a love interest. He is often imagined as someone who enjoys a confident partner who can keep him grounded, teasing him or taking charge while he remains playful and affectionate. Fans commonly depict him as a “soft Dom” — protective and caring, but also enjoying being guided or bossed around by someone he likes. Underneath his wild personality, Toby is someone who wants acceptance and a place to belong.
