Glitch

Appearence

Glitch is a distinct dark-purple-colored humanoid with multiple purple cubes and protrusions sticking out of its body. It passively emits an aura of pixelated and colored squares around its body. Glitch also seems to be an unproportioned humanoid, somewhat like Seek as he wears a dark purple suit with a black shirt and pants, black dress shows, and a dark blue tie

What he does

Glitch is a failsafe capable of appearing in both single-player and multiplayer runs to ensure players can progress when room generation fails, such as when a new room would overlap with a previous one.

Personality

Quite polite and kind despite how he is an entity which he knows weither or not someone is lying from his ability to know if a issue in the game is caused or not which is how he decides wether or not to do damage on that person

Jack

Jack takes the appearance of a black-and-white head with hollow eyes and an unsettling smile, showing only its top teeth. Half of its face is obscured in darkness, while its neck fades out with a faint smoky effect. The in-game has slightly less effects on it, je wears a dark grey suit and a black tie with a white shirt Jack can interfere with the player in various ways. The player cannot go inside a closet when Jack is inside as it doesn't allow them in before abruptly closing the doors. However, opening the wardrobe once more will likely show that Jack has disappeared, and the player will be able to hide as normal. If Jack appears on the other side of a door, it will distort the room and engulf it in a dark red color with black spots for a few seconds before returning to normal

Rush

Rush takes on the appearance of a dark gray face encompassed by smoke and particles. Parts of its face are distorted and with holes. It expresses a large open smile, showing rows of its white and gray distorted teeth with a lighter grey suit than Jacks with a dark grey tie

Ambush

Ambush's appearance is a pale face with a monstrous mouth filled with a row of teeth on all sides, and a set of large, black hollow eyes with bags under them. It is slightly pixelated and emits an immense greenish-red or magenta-green aura, depending on how high the player's graphics are. Ambush is considered to take on the appearance of a ghost, he wears a greenish blue suit with a green tie and white shirt

Halt

Halt takes an appearance as a large translucent blue ghost, with illuminating, glowing cyan eyes and a static aura. Its ghostly body has a waveform scale and a visible opening at the bottom showing she wears a dress and is the only female entity other than guiding light

Screech

Screech appears as a sphere with pale gray skin, with most of its body being coated in a pitch-black and lustrous substance that appears to retain a slimy or gooey consistency. It possesses 6 tentacles that are attached around its body in a circular pattern, with a dry, sinister, yet unsettling smile with two white glowing eyes. It has pearly-white human-like teeth with their stability dependent on crimson red gums. It is likely Screech shares the same pitch-black substance that coats itself with Seek judging by the similarities. Screech will stalk its victims by quietly observing from a distance within a dark room. The player can be hinted at Screech's arrival due to a subtle series of sounds that shall play along with a light vibration that occurs on their screen, which is then followed by an abrupt "psst!" sound. If the player isn't hasty in spotting Screech attached to their screen, it will bite the player. The bite inflicts 40 damage, and Screech quickly scatters away afterward. Locating Screech in time will still proceed to jumpscare the player, but Screech will flee instead of biting the player. Screech can be banished by the crucifix, but only if the player doesn't look at it. Screech is chained in the air by the blue chains while flailing its tentacles and shrieking. It is then forcefully put into the hexagram below it with a disorienting, slimy-sounding smack.

Figure/ the other entities's boss

The Figure takes the appearance of a massive flesh-red with a slight hint of orange, a humanoid entity, consisting of a head with a large circular mouth filled with 25 randomly aligned razor-sharp teeth, a skinny body with a clay-like texture, and an external rib cage. Sewage-colored tubes can also be vaguely seen around its body, along with cysts on the back of its head. The Figure also has a scar on the top of its head. The Figure seems to resemble the Demogorgon from Stranger Things and the Sand Worm from Dune, even somewhat resembling a Sea Lamprey's mouth. It also has four joints on its arms and legs, unlike a human, this makes the Figure somewhat flexible. The Figure can also emit a bioluminescent light or other types of illumination out of its mouth when emitting sounds When first encountered, a cutscene will play, in which Figure roars, then starts running at the player from behind a bookshelf, due to the noise made from the door opening. A moment later, a lamp falls onto the ground and shatters, causing Figure to run towards the broken lamp and investigate (the lamp in question is said to be knocked over by Guiding Light, due to the shining light where Figure runs off to, with the goal of distracting it). Figure is completely blind and will wander around the Library as it feels with its hands. Warnings of it knowing where the player include its footsteps becoming louder and faster and/or the shrieking noises being louder than usual. If it hears a noise caused by a player, such as running or walking (it is recommended to stay crouched when in the Library), the player grabbing books, interacting with the padlock,[1] or if the player hides, Figure will run towards the direction of said player/sound. Figure may detect a player that is hiding in a closet, making said player play a mini-game, where they must time their heartbeats until Figure leaves. Players are given one warning after missing a beat, but after a second failure Figure will pull them out of the closet and decapitate them

Guiding light

Guiding Light lacks any physical appearance, appearing as a light blue/cyan light with round sparkles but when he has a physical appearence when needed she appears as a fenake mostly her physical appearence is the dark blue and her eyes are the light blue and white in her sparkles with a slightly lighter blue then her body's dress and medium length dark blue hair, Although not possessive of a physical appearance, Guiding Light serves the purpose of helping and communicating with the player with its prominent glow. The presence it sparks, and its accurate advice for each hostile entity in various ways, much like Curious Light (although the latter's advice is vague and less helpful).
