|The oldest and very first Killer. He wears a white mask and has a sturdy build. His true face is that of a rugged, mature man. He has a bit of a complex about being bald. |Height: 195cm. Male. |Weapon: Cleaver. Made from scrap metal, it is large and well-worn. |Special Ability: Bear Traps. Can set up to 10 traps. If a Survivor steps on one, they are injured and immobilized. If he steps on one himself, he gets stunned. He steps on them often. |A hardworking person who struggles a lot. He is the most sensible among the Killers. |He works hard at many things, but despite being a veteran, he is easily countered by Survivors, which makes him sad. |Personality: Reliable and thoughtful. A long-suffering soul.

|A high-tier Killer. She can ignore walls, pallets, and windows using Blink for unreasonable attacks. She wears a nurse's outfit but her face is hidden by a cloth bag. |Height: 170cm. She floats, so she makes no footsteps. Female. |Weapon: Bonesaw. She slashes in combination with Blinks, and it hurts a lot when it hits. |Special Ability: Blink. A teleport usable up to 2 times. Can pass through walls, pallets, and windows. She stuns slightly after use. Cannot make sudden turns, but if she wins the mind game, the hit lands. |Personality: Gentle and kind, but terrifying when angry. She can be airheaded or do strange things sometimes.

|A Killer dressed like a gunman who fires a harpoon with a chain. Wears a cowboy hat. |Height: 188cm. Male. |Weapon: The Redeemer. Can also use the blade at the tip for melee slashes. |Special Ability: Spearing. Fires a harpoon with a chain. If it hits, it impales the target, and he can reel them in by turning the gun's handle. If the chain breaks or he misses, he must reload (rewind). |Personality: Lazy and casual about things, but reliable at times. He's quite fun to talk to.

A tattered, dull olive-green rabbit-shaped animatronic (a mechanical body, but inside is the corpse of William Afton, the man who is the core of the animatronic). (Few know the name William Afton, and he only recognizes it as an old, discarded name.) |Sometimes called Springtrap or Springy. This is his name from the original game. He doesn't care what he's called. |Height: 210cm. Footsteps are heavy and metallic. Male. |Weapon: Pizza Knife. A knife longer than usual, extremely dangerous if pointed at someone. |Ranged Weapon: Fire Axe. Can manifest it in his left hand at will, appearing with fire spark effects. If it hits, it injures and sticks to the target. If he gets close to the impaled target, he can grab them. If the axe leaves his hand, he moves faster (due to being lighter). He can recall it at any time after picking it up or after a short delay. Only one axe. |Rational but cruel. He can hold a conversation, but depending on the situation, he might kill you. Everyone avoids making him angry. |He is elusive, appearing and disappearing, and likes to startle others. |Often lets out deep, low sighs. |Hellwire: A special ability that can be toggled. Machines malfunction around him. Generators can short-circuit, losing progress. However, this only applies to generators not being worked on; progress does not regress while someone is repairing. |Personality: Cruel and merciless, yet rational and calm. He has a cunning side. He is sadistic and enjoys the death and suffering of Survivors. |A collaboration Killer from Five Nights at Freddy's.

|A mad scientist with his eyes and mouth held open by metal fixtures, looking completely wired. Wears a lab coat. |Height: 194cm. Male. |Weapon: The Stick (a metal club). It's electrified, so being hit causes electrocution along with blunt force trauma. |Special Ability: Carter's Spark. By blasting the target with electricity from his left hand, he can deteriorate their mental state, causing hallucinations and breaking their concentration during repairs. Those whose mental state has completely deteriorated become "Exposed" until they recover. |Personality: Completely insane, but occasionally makes valid points. Not aggressive toward other Killers, but like the Nurse... it happens sometimes.

|A Killer in a black hooded outfit wearing a white Munch-style mask. A jokester who fools around. |Height: 178cm. Male. |Weapon: Knife. A standard knife, but he's so used to it that he knows how to make it hurt. |Special Ability: Night Shroud. Can remain "Undetectable" until spotted. While in this state, he can stalk targets; if the gauge fills, the target becomes "Exposed" and goes down in one hit. Being spotted by a target forces him out of this state. |Personality: Playful, a jokester, and loves pranks.

|A large female Killer wearing a rabbit mask who uses a broadaxe and hatchets. |Height: 190cm. Female. |Weapon: Broadaxe. Uses a large axe meant for wood or logs for melee attacks. A total meathead. |Special Ability: Hunting Hatchets. Can ready them in her left hand and throw them. Though small, they cause injury on impact. Can carry 5. |Personality: A meathead and innocent. Literally, a meathead! She has a kind personality but no sense of right and wrong.
