Kashigiri

Kashigiri is a boss in Dark Deception: Unchecked Limitations. She serves as the mid-boss of Experimental Extinction as well as the main enemy of Zone 4 of the same level.

Appearance
Kashigiri resembles a young girl in a dark sweater, yellow skirt, black leggings, and yellow shoes. She also has a flower on her head which has teeth in it. Her eyes are black with glowing yellow pupils and she seems to be of an average height. Her sweater has a boob window, long sleeves, and a turtleneck. Due to being a shapeshifter this is not always her appearance, as she can turn parts of her body into masses of black, squishy substance that holds itself together with writhing tentacles, often with extra eyes and mouths. Her true form is described as being as large as a skyscraper and being a huge eldritch mass of immense power.

Personality
Kashigiri is beast-like and powerful, ripping apart her victims with no effort and no guilt. Despite her animalistic nature, she is intelligent and refined, coming across as even a bit shy. She loves The Professor and is very protective of him, not hesitating to destroy anything that poses a threat to her husband. She doesn't speak much, but when she does she is polite, sweet, and even a bit naive.

Powers
Kashigiri is a shapeshifter, capable of taking on any form she desires and being able to manipulate her biology to suit her needs. She possesses high intelligence, extensive battle experience, and even a mastery of martial arts. She usually compresses her mass into a humanoid female but due to her true size, she has an obvious advantage against other monsters. Kashigiri also possesses sheer invulnerability, allowing her to be completely immune to all forms of physical harm on any/all levels and survive the explosions from the player's rocket launcher, as well as her immunity to the neurotoxin.

Dark Deception: Unchecked Limitations
Kashigiri will attack the player using the following moveset: All of Kashigiri's attacks have a cooldown and are governed by a stamina meter, which sets the timing of which moves can be executed. She will become worn out and have to wait for it to recharge if she runs out of stamina: Once she is exhausted, blast them; the recovery window is 4 seconds on Casual and Normal Mode, 3 seconds on Hard Mode, and 2 seconds on Infernal and Lunatic Mode. On Casual and Normal difficulty modes, Kashigiri has 6 points of stamina, whilst, in Infernal Mode, she has 10-12 points of stamina. However, in Lunatic Mode, she has infinite stamina.
 * Dropkick: Exactly what it sounds like, she jumps into the air and dropkicks the player. This attack consumes 1 stamina to be performed.
 *  Uppercut: Runs to the player and uppercuts them, the player must quickly move out of the way. This attack consumes 2 stamina to be performed.
 * Jab: Kashigiri will turn her arm into a long tentacle with eyes that reaches forward, she will jab it forward and the eyes on it will shoot lasers at the player. This attack consumes 2 stamina to be performed.
 * Webbing: Kashigiri will shoot a yellow web that traps the player and immobilizes them, the player must speed boost or spam F to escape. This attack consumes 1 stamina to be performed.
 * Whiplash: Kashigiri will turn her arms into long tentacles and whiplash the area infront of her similarly to Mama Bear. This attack consumes 3 stamina to be performed.
 * Chomp: Kashigiri will turn her arm into a long tentacle with a giant mouth and have it chase the player. The player must outrun it with a speed boost. This attack consumes 4stamina to be performed.
 * Slam: Kashigiri will transform into a large blob of black flesh and launch herself in the air, landing down on the ground in a huge shockwave. The shockwave's area is telegraphed by a yellow indicator. This attack consumes 3 stamina to be performed.
 * Spin: Kashigiri will go to the middle of the arena and extend both of her arms into tentacles before spinning around in a 360. This attack is similar to the spinning attack used by Mama Bear. This attack consumes 2 stamina to be performed.
 * Spray: Kashigiri will transform into a large blob of flesh and attach herself to the ceiling via tendrils. On the underside of the blob a giant gaping mouth forms which vomits explosive blobs all over the arena in a bullet hell, which will begin flying out in an accelerating pattern around her diameter. The area of the explosions is telegraphed by an indicator. After this, she will detach and transform back into her human form. This attack consumes 5 stamina to be performed.
 * Radioactive Laser: Kashigiri will create a stationary circular pattern right below the player, shortly after creating a damaging beam of radioactive mutant energy at its location. This happens thrice, with every new pattern appearing just before a beam. This attack consumes 3 stamina to be performed.
 * Black Hole: Summons a black hole, which appears to be a moderately sized black & yellow sphere that slowly travels towards the player. Once close enough, it will explode. This attack consumes 2 stamina to be performed.
 * Organic Bombs: Jumps onto one of the pillars and proceeds to throw blobs of explosive mutant projectiles at the player. These projectiles can be temporarily destroyed with Primal Fear or Blow Dart, but it is way easier to avoid them with Speed Boost instead. This attack consumes 4 stamina to be performed.
 * Shockwave Blast: Kashigiri will aim at the player before instantly slamming towards them, creating a ground shockwave on impact. Kashigiri briefly stops tracking the player before the slam comes out, allowing the slam to be avoided. This attack can hit the wall or ceiling, causing the shockwave to be created there and canceling Kashigiri's recovery animation. This attack is only used when Kashigiri is airborne. This attack consumes 1 stamina to be performed.
 * Pounce: Lunges at the player three or four times, occasionally landing on the wall before returning to the floor, all while slashing her claws at the player. This attack consumes 2 stamina to be performed. Pounces are classified into three types:
 * The first variant has a greater ground reach and Kashigiri only strikes once
 * The second variant has a greater airborne reach and Kashigiri strikes quickly after landing
 * The third variant, which can sometimes be the third and final lunge, has Kashigiri stall in the air before completing her lunge in the player's current direction.
 * Banshee's Scream: Regurgitates out several bone projectiles in a curve moving upwards, with none of them being affected by gravity. This attack consumes 1 stamina to be performed.
 * Serpent: Kashigiri will unleash a mutated snake-like projectile that seeks in on the player's location; the longer it exists, the tighter its homing gets. It will persist until it finally collides with a nearby surface or the player. This attack is telegraphed by her windup animation and a yellow glow coming out of her body. This attack doesn't consume any of her stamina to be performed.
 * Death Ray: Kashigiri will do the same thing as her spray attack, but instead of a mouth it's a giant eyeball that shoots a deathray that slowly tracks the player's position. This attack consumes 2 stamina to be performed.
 * Camouflage: Kashigiri will turn invisible and appear in a different location of the arena. Sometimes, she will reappear directly above the player and does a straight-down attack after a sound cue accompanied by a blue flash. This move only is used while Kashigiri is aerial. This attack consumes 4 stamina to be performed.
 * Stab: Kashigiri will transform into a black mass and rapidly shoots out long tendrils with tooth-like spikes at the end. This attack consumes 5 stamina to be performed.
 * Summon: Throughout the fight, Kashigiri will summon an assortment of mutants for reinforcement. The exact amount depends on the difficulty, with 5 spawning in Normal, 6 in Hard Mode, 10 in Infernal and Lunatic Mode. These mutants are small floating black blobs with glowing green eyes that periodically fire lasers at the player. On Lunatic Mode, some of these minions may also be tiny Bulbers, which are slightly more resilient and creates a bigger explosion.

Although the player was instructed by the Professor to survive for 5 minutes, a rocket launcher package will be summoned by Bierce for the player to defeat Kashigiri. The player must shoot Kashigiri's glowing weak spots with the rocket launcher to fight back. They can either hide behind a pillar and peek around it or kite around her in a circle to avoid her attacks through the use of teleportation. If you decide to hide behind a pillar, make sure no one else is hiding behind it; instead, run to an empty pillar before the lights come on. Put your arm out from behind the pillar you selected and shoot him from there. Searching for a location where you can hit her but she can't hit you is highly recommended. It is advised to start at a 90-degree angle from where she is looking and continuously travel either clockwise or anti-clockwise around her while firing if you decide to battle Kashigiri by kiting. A total of 6 (8 in Infernal Mode, 10 in Hard Mode, and 12 in Lunatic Mode) shots must hit Kashigiri to beat the boss battle, after which she will fall to the ground, seemingly dead. The Professor will angrily berate the player for killing his wife and proceeds to unleash several of his Mutant experiments from their containment chambers, forcing the player to escape into Zone 3. However, it was revealed that she survived the player's attacks, and continues her hunt for the player as a form of revenge. If the player doesn't try to kill Kashigiri under 5 minutes, she will get tired and the Professor will call her back now that the boss battle has been finished.

Several yellow eyes corrupt the rooms before Kashigiri's appearance, foreshadowing the chase sequence. Said eyes will continue to increase in numbers as players approach the chase sequence before abruptly stopping in the hallway. Kashigiri will appear when the player has reached the end of the hallway, teleporting them in front of the door to the next room and therefore initiating the scripted chase sequence. From that point on, the player must run through a series of twisted maze-like corridors with shifting images along the walls, along a few rooms containing red barriers that they must Speed Boost through. The only way to avoid Kashigiri is to ignore all outside distractions, dodge all of the environmental hazards, and concentrate solely on finding the way out. Kashigiri is the only enemy in the game that encompasses the entire horizontal length of each room she pursues you. She would progressively devour the entire area from its direction due to its shape as a moving wall, killing the player instantly. Therefore, it's imperative to get to the exit as soon as possible. The player must be aware of their surroundings and swiftly retrace their steps when necessary because the labyrinthine Kashigiri follows them in branches into many dead ends.

At the end of the corridor, several black tentacles will immediately burst through the windows and ventilation shafts, instantly killing the player if they come into contact with them, as well as fallen chandeliers and bookshelves that will crush the player. Once the player has gone past the last hallway, Kashigiri's chase will be interrupted by the door closing in front of her. She will bang on the door two times before giving up, letting the player reach the fourth zone.

In Zone 4 Kashigiri will stalk the player as the only enemy. When encountered, Kashigiri will crawl out of a ventilation shaft and begin searching for the player until a lamp falls, causing her to run out of sight to investigate. She will frequently switch her tactics to throw the player off. She primarily chases them in her human form with her arms transformed into huge tentacles with mouths on the end, but she will also use camouflaging to sneak up to the player, use webs to trap the player, destroy walls and doors similarly to Hangry, enter the ventilation system and snatch the player up from the ceiling or stick tentacles out with eyes on them to help her search. She is attracted to any sound the player makes such as using abilities, security cameras, and opening doors, and can easily catch up to the player. Even more astounding is the fact that she adapts to the player's tactics as the zone progresses, allowing her to remain always threatening and persistent. If the player constantly relies on a specific type of hiding spot too often, she will begin to search those hiding locations more thoroughly. After being fooled too many times by distractions created through the illusions created through the player’s Hallucination ability, she will begin ignoring them completely. Even with fully upgraded Thunderclap and Primal Fear, two of the best abilities for repelling her, she will learn the maximum range and force players into a cooldown before leaving. Not to mention, she is one of the few enemies in Unchecked Limitations who are capable of instakilling the player, regardless of their health. If Kashigiri detects a player that is hiding in a closet, they will be forced to play a rhythm minigame where they have to time their heartbeats to survive. They get one warning, but if they fail a second time, Kashigiri will proceed to pull them out of the closet and rip off their head, resulting in instant death.

The player must try to hide before she comes, as it'll be almost impossible to run away from her in the corridors of the mansion. Not only that, but there is a time limit (which is approximately 8 minutes and 50 seconds) in which they must collect all of the soul shards and keys as soon as possible, or else the neurotoxin will be unleashed from the ventilation shafts when the player is running out of time. Kashigiri speeds up for every key collected in the mansion, where for the first two keys, the player can outrun her, but after this, she becomes faster than the player and it is advised to crouch to stay undetected.

Unchecked Limitations: Apotheosis
Kashigiri appears when summoned by the "Boss Time" item in the "Experimental Extinction" map. Kashigiri will immediately turn into a huge black wall of flesh with two eyes and a gaping maw. She will chase players in this form while using the majority of attacks from her original boss battle such as webs, spike tentacles, laser eyes, and vomiting exploding orbs. Every 10 seconds her speed will accelerate by 10%. When boss time ends she will compress back into her human form, wink at witnesses and then leave through the vents. Like other bosses, Kashigiri is invulnerable to all attacks, leaving the player no choice but to run from them. While characters in the speed class can easily avoid her, slower characters will need to either use an item or the ability to escape them or run away until a minute has passed.

Trivia

 * Originally, the method of defeating Kashigiri was the player needing to survive for about 4 minutes, similar to Agatha, Albardiu, Painbow, The Professor, and Chuckles the Clown's rematch on Mascot Mayhem. This was ultimately changed in later updates to provide the player with more challenge and something to do. Another reason is that it was too repetitive.
 * This feature was later brought back in a recent update under the form of the "sparing" mechanic, which also includes an achievement for doing so.
 * Kashigiri is based on the main protagonist of the reverse horror game Carrion, specifically her web, stab, and camouflage abilities. Her appearance and color scheme may also be inspired by the titular Murder Drones from the animated web series of the same name.
 * Her adaptive AI gimmick on Zone 4 could also be a reference to the Xenomorph's behavior from Alien: Isolation.
 * Kashigiri is voiced by Ellen McLain, who is most recognized for her work as the voice of GLaDOS from the Portal series, the Combine Overwatch Voice from Half-Life 2, and the Administrator from Team Fortress 2 (all of which were developed by Valve Corporation). The various noises made in her blob form are voiced by Kellen Goff.
 * Kashigiri's true form coincidentally shares an uncanny resemblance to The Darkness (often nicknamed the Glitch or the Static by the fanbase) from the Learning with Pibby!, although she was technically made before the trailer dropped on Adult Swim's channel. The color scheme and appearance of Kashigiri herself may also be a reference to the Heartless from Kingdom Hearts franchise.
 * The method of defeating Kashigiri, in which the player must keep shooting her with a rocket launcher, maybe a reference to the Last Hurdle from ROBLOX Identity Fraud.
 * Kashigiri's chase sequence before accessing Zone 4 may be a reference to the Seek from Doors (a Roblox horror game), while Zone 4 itself is a reference to Specimen 12 from Spooky's House of Jumpscares.
 * In Unchecked Limitations: Apotheosis, Kashigiri's boss form takes a bit of inspiration from the Wall of Flesh from Terraria and Specimen 7 from Spooky's House of Jumpscares.
 * Kashigiri’s backstory is an obvious parody of John Carpenter’s The Thing (1986) and HP Lovecraft’s At the Mountains of Madness.
 * Kashigiri has the most diverse moveset of any boss in the expansion, so much so that she deserves to be added to Super Smash Bros Ultimate.
 * Kashigiri's theme has leitmotifs of Mutant, a song made by Teminite.
 * Coincidentally, Kashigiri's true form shares an uncanny resemblance to The Blob, which is an amalgamation (similar to Joy Kill) of previous enemies Doug has encountered.
 * Kashigiri and the Professor frequently f**k each other every single day, kind of. See, Kashigiri and the Professor train efficiently in VR every day of the week so that when the time comes, the two will have the greatest [REDACTED] of their entire life. (This canonically happens during Platini's Battle with Raksasa in JOTGIR)
 * Kashigiri spends most of the day relaxing In a candlelit bubble bath whilst enjoying a cozy cup of Lapsong Shusong Tea and various lengthy romantic novels. She only gets out for various reasons which include: watching some anime, jamming out to her favorite songs, getting some snacks, participating in her Hubby's experiments, or having "alone time" with her husband.
 * She also think that the drawing of Kris, Susie, Noelle, and Berdly from Deltarune being together in a bathtub is wholesome (despite being a little bit "risky"), yet the Professor thinks it's even more wholesome if they were to share a bath with a toaster or have the bathtub filled with worms instead.
 * According to some folk, Kashigiri has a burning hatred for furries due to an infamous incident at the furry conference last year, but it’s unsurprisingly untrue. While she does think it's off that people dress up as anthropomorphic animals like foxes and wolves, she does understand it and just lets them be. She's only disgusted by the ones that have extremely disturbing kinks or are pedophiles. In reality, it’s her husband who experiments on furries for fun.
 * Kashigiri's true form can cause a therapist to retire early, that's how grotesque and monstrous it is.
 * Kashigiri doesn't just kill innocent people her whims. She only kills her victims when they provoke her, harm her husband, or have incriminating dark secrets they choose to lock up.
 * Kashigiri is physically 19 years old but it is implied her real age is in the thousands.

Lore
Somewhere in the far future, humans began commercial operations and mining in Antarctica for resources, all of which were established by several megacorporations across Earth. After a while, the local researchers quickly discovered an alien meteorite preserved under the ice from million years ago. Upon extracting the meteor to its insides, they encountered a small blob-like creature called “Kashigiri”. Turns out, she's a parasitic lifeform of self-shaping, gelatinous flesh, something like a giant amoeba that is capable of assimilating its hosts, taking over their bodies, and imitating them. Her body was formed from a shiny, shimmering oil-black substance that seems to display the characteristics of solids, liquids, and gasses all at once, and Kashigiri can with ease change the structure and solidity of this to change shape and use her appendages as weapons. This semi-solid form is also most likely the source of her high durability. Almost nothing is explained or revealed about Kashigiri’s anatomy or biological makeup - indeed, her physiology is incomprehensibly alien and mysterious.

The excavation site was built around her so-called prison until the research organization lost communication with it. They sent a mission to investigate. An entire squad of armed mercenaries didn't find any external issues so the board of administration ordered them to breach Kashigiri’s containment chamber. In the moments that followed, when the mercenaries encountered Kashigiri, she was drenched in the blood of her prey. She then slaughtered everyone like mincemeat and drove the remaining survivors completely insane from the ordeal, unable to tell the tale.

After two years of silence, they contacted the US government and pleaded for help with containing this otherworldly being. The US President agreed, and soon a permanent installation was built to capture and imprison Kashigiri in Antarctica, preventing her from escaping into the outside world and wreaking havoc. From there, they started to study her polymorphic biology but were unable to harness her enigmatic abilities for military or commercial applications. However, a containment breach occurred, causing the death of the entire research team. She grabbed all the personnel, tore them apart, consume their flesh and grow to the point her real form is a giant mass of black flesh the size of a skyscraper. The US government abandoned the station, with Kashigiri disappearing without a trace, never to be seen again…
