Jack

Jack is a minor entity in DOORS, residing in The Hotel and in The Mines. Its main purpose is to frighten players, as it does no damage.
== Appearance==
Jack takes the appearance of a black-and-white head with dark, 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 version has slightly less effects, has a smaller mouth and less teeth shown.
== Behavior==
Jack can interfere with a player in various ways. A 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 a 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.
===Notes=== 
*Jack has a \frac{1}{200} (0.5%) (\frac{1}{20} (5%) before Hotel+ Update) chance to appear from a closet and locker and a \frac{1}{2000} (0.05%) chance to appear from a door. However, the “Nothing?” candy increases its chance to spawn behind a door.
*If there was a window in the room Jack appeared in, the rain outside will also turn blood-red, lingering forever unlike the rest of the room.
*If Rush or Ambush spawn, then Jack will temporarily de-activate and be unable to appear, likely to prevent cheap deaths. Jack will re-activate upon opening another room door, meaning it is advised to not open the next room door while Rush or Ambush are active, as doing so will allow Jack to appear again, potentially (albeit rarely) getting a player killed when they attempt to hide.Although there is no way to prove this without direct confirmation from the developers, this has been researched via YouTube. Every clip that has been found with Jack appearing during a Rush or Ambush scenario has been when the door to the next room has been opened. However, Jack will not de-activate upon Blitz's spawning (if playing with "Blitz, Oh" modifier), meaning it can still ruin player's run.
*Jack can appear in every room in the main floors, except for The Reception and The Adit.
**Jack has been seen in the Electrical Roomhttps://youtu.be/pQ-30QVd7UA?si=73-oZEBpsD_W4ujZ&t=354 and in The Damhttps://youtu.be/pQ-30QVd7UA?si=sj_HVhAdQp7oFWk7&t=233, but only with the "Nothing?" candy modifier; it is unknown if it can spawn naturally (without candies) in both of these rooms.
*Jack can spawn as early as Door 1, right after The Reception, in the Hotel; and as early as Door 101, right after The Adit, in the Mines.
*Jack can also appear in Seek's chase sequence.https://www.youtube.com/watch?v=-H2A-EBmk9U
*If Jack appears during the chandelier part of Seek's chase sequence, all of the hands will become red.
*Rush can trigger Jack when it opens the next door.
*If Jack spawns in a closet, it will briefly flicker the lights around it.
*Jack can appear multiple times in one closet as well as appearing more than once in a single run.
*When Jack appears and a player dies to Rush or Ambush, the death message that pops up says "You died to ... because you couldn't hide."
*With the addition of The Haunt Update, eating a 'Nothing?' candy drastically increases the spawn chance of Jack's Hallway Form. However, the "Meet Jack" achievement is not obtainable with the Trick or Treat modifier.
=== Super Hard Mode ===
* Jack wears glasses and looks "surprised", paying a homage to the internet meme, "Wojak" (more specifically, the "Soyjak" variant of the meme), which Jack's name references.
*Jack seems to have a higher chance of appearing upon opening the next door.
== Bugs== 
* Jack can sometimes make the room red without its appearance, caused by lag.
*Jack can sometimes make dark rooms a little bit lighter when outside the dark room. When a player enters the room, it has a chance to fall dark like normal.
* There was a bug in which a player could walk through Jack's closet jumpscare and fall into the void. This has since then been patched.
**However, there was no documentation of this.
*There is currently a bug where if a player will get Jack's closet jumpscare, it will not disappear visually, but players will be able to use the closet.
== Trivia== 
*Ambush was originally going to be a character that behaves like Jack but was changed to be a standalone entity instead.
*There was originally going to be an entity similar to Jack that would have the same function as Jack except they would appear under beds instead of closets, but Lightning Splash decided to not go through with it. However, Ghostly Wowzers has stated that this entity may be added in the future.Q: "Will there be a Jack for Vents or Beds????" A: "there originally was going to be a jack-equivalent for hiding under the beds but wasn't added due to splash not going through with it (though it might come back at a later time)" – Ghostly_Wowzers 
**This entity could have been what Ambush was back then.
*Jack was originally going to be called "Mobble".
**Jack was one of two "Mobble" entities during DOORS' development, the other being Ambush. 
***Despite the achievement being called "Meet Jack", the code source is "EncounterMobble".Proof
*Jack, Glitch, and Shadow are the only entities that deal no damage upon jumpscaring a player.
*Jack has a shorter jumpscare when appearing behind a door than its closet jumpscare.
*Jack's name is a reference to the popular internet meme "Wojak", as its earlier design was photoshopped onto a picture of a Wojak by Redibles. "the wojack thing was because red made photoshopped jack and put it in a wojack meme" – Ghostly_Wowzers 
**The older version can be found in-game,"in-game version uses the older design" – Ghostly_Wowzers whereas the updated version is the one seen on the wiki, due to Wowzers wanting Jack to look good where it can be seen best."i updated jack for the wiki to look more presentable" – Ghostly_Wowzers 
***If Wowzers were to edit any of his entities in DOORS, it would be Jack.Q: "If you could remove/edit any of the (current) Doors entities, which would it be and how if editing?" A: "id probably just edit jack, it still uses the old one" – Ghostly_Wowzers
*Jack's image when inside a closet is flipped horizontally. 
**This is due to Jack using beams for its texture, and not BillboardGuis or particles.
*Jack's filename is "scaryface".
*Jack's jumpscare sound comes from this audio.
*Redibles has expressed interest in a UGC backpack of a closet with Jack inside.Q: "closet backpack with Jack inside" A: "sounds creative" – RediblesQW, Twitter
*Jack will most likely appear on other future floors."timothy and jack will most likely appear in future floors" – Ghostly_Wowzers
*Jack's design was not difficult to make, being mostly drawn in under a day.Q: "Also, How hard was it designing the Characters (Rush, Ambush and Jack)?" A: "not that hard, they were mostly finished in under a day" – Ghostly_Wowzers
*Jack's achievement description may be a reference to a specific episode in the series made by Sr Pelo called "Spooky Month", a Halloween themed animation series which started as a joke, but it has since then become an entire series. The reference is in the episode 'It's spooky month', in which there are multiple instances where a character in the show named Ooga Booga says 'Ooga Booga!' and the other characters act terrified.
*Jack can be found in the painting titled "Captain Jack". 
**This is a reference to the YouTuber CaptainJackAttack, since in the painting, Jack is wearing the same hat that CaptainJackAttack wears on his Roblox avatar.
*On August 4, a strange photo of Jack was uploaded by Ghostly_Wowzers, it is unknown if the image has any relevance to Jack's front facing design.
*If Jack spawns in big rooms, like the Library, the Nest, the Electrical room or the Dam, it will cause a massive lag for some seconds in low-end devices.
**This is specially lethal in the Nest, as players can get slowed down during the starting chase and die.
*2 Jacks can spawn at the same time behind the same door, forming a permanent blood chamber. The red colors will stay forever, but the moving black dots will slowly fade away, like in a normal blood room.
*Jack has a strange bug, where after it appears it does not go away. This Jack that is not out of the closet after appearance will not make another jumpscare.
