Interlude[]
Boomstick: The art of dodging is one of the most refined techniques in the history of fighting because how else are you going to beat the crap out of your opponent if you can't stop them from beating the crap out of you.
Wiz: And when it comes to dodging, these two reign supreme as the most untouchable combatants.
Boomstick: Korosensei, the unkillable teacher of the Assassination Classroom.
Wiz: And Sans, the enigmatic skeleton from Undertale.
Boomstick: He's Wiz and I'm Boomstick.
Wiz: And it's our job to analyze their weapons, armor, and skills to find out who would win... a Death Battle.
Korosensei[]
Wiz: Assassins come many different forms, each possessing a unique set of skills to help them kill their target without leaving a trace, but none of them could compete with the greatest assassin of them all: The Reaper.
Boomstick: This guy was legendary for pulling off impossible assassinations, in fact he was so good at killing that other assassins feared having to face him. There was nobody on the godd*** planet who had the balls to stand up to this guy… except for his own apprentice who turned him into the authorities and stole his title. To make matters worse, the now former Reaper was sent to a research lab to be experimented on by madman Kotaro Yanagisawa.
Wiz: While Yanagisawa wasn’t the nicest person around, he was a genius with a plan to mass produce antimatter by injecting it into the cells of living hosts and the original Reaper was perfect the life-threatening procedure. However, the Reaper was a bit more cunning than anticipated, by manipulating the researchers, he controlled the experiment so that the antimatter injections would bestow upon him superhuman abilities to make him the ultimate killing machine.
Boomstick: And in between those operations he would spend time with his caretaker and Yanagisawa’s fiance Aguri Yukimura, a woman that the Reaper took a liking to due to her compassion and large breasts. That's right, the most dangerous man in the world is also a pervert. The Reaper would continue biding time before his escape until a rat undergoing the same antimatter experiments suddenly exploded.
Wiz: The good news was that the rat had been moved to the moon for safety purposes, the bad news was that the explosion was so powerful that it destroyed 70% of the moon and the Reaper was destined to do the same to Earth next year. Upon hearing this, The Reaper escaped and used his newfound powers to kill everyone in the facility, but came to a halt when Aguri attempted to calm the assassin down and was killed by the lab’s defense system.
Boomstick: Feeling guilty that he couldn’t use his powers to save the woman he loved, the Reaper made a promise to Aguri: that he would not use his talents to hurt people, but instead use them to protect and guide those who needed his help, which just seems like a waste when your entire body is a living weapon.
Wiz: The Reaper later became as a teacher at Kunugigaoka Junior High School and began teaching the academic failures of Class 3-E, and to make his powers appears more friendly he altered his body to take the comforting appearance of a… smiling… yellow… octopus. It might not be the most appealing form, but at least he looks slightly less like a vicious killer.
Boomstick: Obviously the world leaders weren’t too happy with a living nuke acting as a teacher so The Reaper promised to teach his students to become master assassins specifically trained to kill him, but after a couple failed attempts the students realized that this monster might be unkillable, but that also made for the perfect nickname for their target: Korosensei, which literally means “unkillable teacher.”
Wiz: While he has dedicated himself to a pacifist lifestyle, Korosensei possesses numerous abilities perfect for avoiding any possible assassinations. Thanks to his antimatter physiology he is immune to all sorts of weaponry including knives, bullets, poisons, and even explosives. In fact, his body is so difficult to harm that the government had to create weapons using special material that can harm antimatter beings like Korosensei, but even if he were to be hit he can simply regenerate all manner of wounds in an instant although he does drain his stamina upon doing so.
Boomstick: Korosensei can also fly, liquify his body, change color to camouflage himself, and even shed his own skin and use it to ensnare people, if that's not gross enough his body is covered with a weird mucus that acts like an adhesive so strong it can solidify water. But most importantly as a giant octopus he has tentacles everywhere in his body and their pretty d*** functional. He can stretch his tentacles to reach far away objects, and spin them around to use them like drills.
Wiz: However, the greatest function of these tentacles is their incredible speed. Korosensei can move his body with incredible speed and precision, reportedly at maximum speeds of Mach 20 or over 15,000 miles per hour. At these speeds Korosensei can perform entire actions before his attackers can react, and in addition he can create after-images to perform several tasks at once while wearing different outfits for his own amusement.
Boomstick: It sort of like the shadow clone technique from Naruto.
Korosensei is seen tutoring his students individually using his afterimages with each clone wearing a different headband to represent the subject being taught.
Terasaka: Man, this is balls. He seriously have to wear a different headband for each subject?
Korosensei then approaches his student wearing Naruto’s iconic headband and whisker markings.
Terasaka: Give me a break man! Naruto’s not even on the test!
Wiz: To back up his speed, Korosensei possesses incredible senses. He can pick up on low frequency sounds, recognize people by their scent, and with his kinetic vision he can keep track of and react to objects that can move faster than himself. This makes Korosensei extremely difficult to catch off guard, but due to his deal to the government he isn’t allowed to harm anyone who tries to kill him, so instead he developed a strange habit of retaliating through grooming his opponents as a means of humiliation. Though if speed isn’t enough to avoid death, Korosensei can concentrate the energy in his body to enter his Absolute Defense form which makes him nearly indestructible for 24 hours, albeit he is left completely imobile.
Boomstick: While seemingly useless, Korosensei later learned that he can use his energy concentration to unleash a powerful energy blast from his tentacles. Ok first shadow clones now Kamehamehas, is Korosensei secretly a weeboo because that would explain a lot.
Wiz: Perhaps, but it's important to remember that Korosensei doesn't just rely on his physical abilities. He was the greatest assassin in the world after all and he has the skills to prove it. Not only has Korosensei mastered the art of assassination, he possess a genius intellect and incredible memory that allows him to learn new information in a brief amount of time including a complete comprehension of anatomy, chemestry, and mechanics. Korosensei combined his intellect and abilities to guide the students of Class 3-E and the results certainly speak for themselves. The students once deemed failures rose to become the best in the school, and their training to kill Korosensei brought them closer to killing the octopus than some of the best armies in the world.
Boomstick: But no matter how hard those students tried, they just couldn't find a way to kill Korosensei thanks to his ridiculous speed feats. He caught a sniper round with nothing but a piece of candy, and moved precise enough to deflect wind debris with his tentacles while carrying two of his students to Hawaii and back. Korosensei even managed to intercept a missle and hold it in place while using it to make instant breakfast.
Wiz: He even dodged the Spear of Heaven, a colossal satellite that fires silent lasers from space. Yet none of that compares to the time he fought his former apprentice who took an advanced version of the antimatter experiment to achieve speeds of Mach 40. Despite being outclassed, Korosensei quickly adapted to his opponents and moved fast enough to block incoming attacks. You would think that a former assassin turned super being would be unstoppable, but Korosensei has many, MANY weaknesses.
Boomstick: He’s pretty arrogant and tends to screw up when showing off. But, if you really want to land a hit you have to find a way to slow him down, and you can do that by destroying or restraining his tentacles. As a bonus, his reaction time also slows down drastically when gets agitated. Sure it may not matter since his regeneration heals all sorts of wounds, though if he gets hit in the heart with enough force, the blow might take him out for good.
Wiz: Korosensei also has a weird sense of shame, which his students were easily able to exploit when they recorded an hour-worth of his embarrassing moments and showed it to Korosensei as a means of distraction. Despite his students constantly trying to kill him, Korosensei actually cares deeply for each of them to the point that he will put his own life on the line to protect them, a weakness his former apprentice attempted to use when he impaled Korosensei’s student Kaede, who was coincidentally Aguri’s younger sister.
Boomstick: That was the biggest mistake Reaper 2.0 could make as Korosensei retaliated with an energy blast so powerful it easily killed the guy that was supposed to be superior to him, and to prove that he learned to use his powers for good he revived Kaede by rounding up the missing body fluids and repaired her wound cell by cell.
Wiz: But, after being exhausted from battle and with the government going all out to protect the Earth, Korosensei allowed his students to finally kill him. Though everyone pitched in and finally landed the killing blow, after everything Korosensei did for them the students were filled with grief for having to say goodbye to their beloved teacher. However, Korosensei’s legacy continued to live on and the students he taught would go on to live prosperous lives, one of them even followed in his footsteps to become a teacher just as skilled as Korosensei.
Boomstick: You know you did some real good when your better remembered as a teacher than a world destroying monster. May nobody forget the name of the unkillable teacher.
Korosensei: Anyways, I hope my students take assassinating me as seriously as I take their education, not that you'll ever pull it off of course.
Sans[]
Wiz: Long ago, humans and monsters lived in peace on the surface, but when war broke out humanity drove the monsters underground and imprisoned them with a magic seal. Though they remained trapped, the monsters took what little hope they had and built a new kingdom free from the cruelty of humanity.
Boomstick: This new kingdom has all sorts of strange inhabitants including a genocidal flower, a sentient doll shaped like a cat girl, and the strangest of them all: a talking skeleton with a knack for making jokes.
Wiz: This is Sans, a resident of the town of Snowdin and brother to the royal guardsman in-training Papyrus. However, much of Sans’ past remains a mystery, the other residents of Snowdin say that the two skeleton brothers just showed up one day and asserted themselves there. The two spent their days aiding the royal guard, while Papyrus would patrol the forest searching for intruders, Sans would spend most of his time acting as a sentry… and sleeping.
Boomstick: And whenever he found some free time Sans would wander off looking for new places and people to test his jokes on, and everything changed when he found a mysterious door in the middle of the forest which was perfect for practicing the most ancient joke of them all: the knock-knock jokes. Surprisingly there was actually someone on the other side of the door who was willing to play along, and even more suprising it was the long-lost queen of the Underground Toriel.
Wiz: Sans and Toriel spent day after day telling each other jokes, until one day Toriel asks Sans to make a promise. Apparently Toriel’s ex-husband Asgore was wanting to wage war on humanity, but in order to break the seal binding the monsters underground he would need a human soul. Toriel asked Sans that if a human were to come through the door, he would watch and protect said human.
Boomstick: Sans kept his promise and sure enough some random kid named Frisk just walked through the door and Sans aided the human on his journey to return to the surface, but it was clear that something was off about this human. Just by reading the expressions or rather lack of expressions on his face Sans got the feeling that this kid has “been there, done that” plenty of times.
Wiz: Whether it was related to his mysterious past or his time spent with the royal scientist Alphys, Sans learned the concepts of time travel and developed the means to detect alterations within the timeline. Turns out that through sheer determination Frisk could reverse time to certain points in order to revive himself from the dead or relive events. If this power was used irresponsibly Frisk could become the greatest threat to the entire Underground.
Boomstick: Which is definitely possible when your possessed by the spirit of a hate-filled child with a mission to destroy the entire world. To make sure that Frisk never became the next horror movie villain, Sans decided to give the child a test when he reached Asgore’s castle. He would decide whether Frisk was truly a good person by using his strange ability to see a person’s LV and EXP, whatever the hell those are.
Wiz: EXP or EXecution Points is the energy accumulated through the killing of others which increases LV or Level of Violence, a measurement of one’s capacity to hurt. In most timelines, Sans would allow Frisk to face Asgore due to the child showing compassion by sparing at least one monster, but during a timeline where every monster in sight is killed Sans detects the massive amount of LV and he is more than prepared to make his last stand.
Boomstick: Sure he may be lazy most of the time, but Sans is more cunning than he seems and quite skilled at fooling his opponents, and while he lacks raw power he has abilities that make him more dangerous than any other monster. Like all other monsters, Sans can utilize magic, but unlike all other monsters, Sans can use his magic to create a special form of attack known as KARMA. With KARMA Sans can hit his opponents with the same attack over and over as long as the opponent is touching the initial attack. This drains the life from opponents over time like a poison, and the more damage built up by KARMA the faster it will drain an opponent's life.
Wiz: Sans implements KARMA into attacks he learned from Papyrus such as his ability to summon bones to attack from below or use as projectiles. He can even use light blue bones to extend his reach though they cannot hit anything standing still. If he needs to reduce his opponent's mobility he can change people’s souls to blue mode in an instant which can increase and alter gravity on an opponent or if Sans feels like it he can violently toss people around though this will heavily drain his stamina.
Boomstick: But Sans needed more than his brother’s tricks if he wanted to keep up with Frisk, so he got himself the Gaster Blasters, a multitude of laser cannons that can spawn out of nowhere. If those aren’t enough Sans can always get serious and use attacks so intense they can hit an opponent from the fourth wall. To enhance the reality warping, Sans can even teleport himself and others through space and seeminly foward in time to an extent. In an instant Sans can change the situation of a battle and trap opponents in mid-attack before they notice.
Wiz: All these abilities do make Sans seem invincible, but he has one very exploitable weakness. His body lacks durability and all it takes is one hit to take him down, but Sans is aware of this and developed a countermeasure by improving his speed and reaction time so he can dodge any attack. While this technique is essential for Sans to continue a fight, he has a limited amount of stamina and can’t keep dodging forever. If he does not end the fight quickly he will take the fatal hit sooner or later.
Boomstick: And if all else fails, Sans can resort to his “special attack” where he uses his teleportation to keep an opponent in place. This does mean that neither side will be able to take action, but it's not like Sans had a chance of winning in the first place.
Wiz: Sans is perfectly aware that he could never stop Frisk for good since the human can always reset the timeline in scenarios where Sans successfully kills him, but Sans continues to fight with the hope that he can convince Frisk to turn back and pursue a more peaceful timeline.
Sans: I can feel it. there's a glimmer of a good person inside of you. the memory of someone who once wanted to do the right thing. someone who, in another time, might have even been... a friend?
Boomstick: Whether or not Sans managed to set Frisk on the right path, he certainly proved that he was one monster you don’t want to mess with. For example, a similar time-warping threat named Flowey, who is literally a flower, had a few run-ins with Sans and had to keep resetting the timeline before deciding it was best to never go near the skeleton to begin with.
Wiz: Sans is clever enough to figure out Frisk’s time altering abilities and determine how many times he died, not to mention he orchestrated Frisk’s encounter with Papyrus so the two would become friends rather than enemies, and thanks to his strange powers, Sans has even managed to create a self-sustaining tornado using nothing but simple trash.
Boomstick: But enough about how smart the guy is, what really matters is how fast he moves. Sans is the only monster who has ever managed to dodge attacks from Frisk, he even did so while taking a nap which implies that Sans has some insane reaction time especially when scaling to Frisk who dodged lightning from a magical goat wizard.
Wiz: The return stroke of a lightning bolt moves at about 220,000,000 miles per hour or over Mach 280,000. However, this is a measurement of Frisk’s reaction speed not his movement speed, but this still means that Sans can dodge attacks from beings that can react to lightning and move fast enough to avoid it. Even more impressive, his dodging ability does not seem to be connected to his reality warping, but rather physical strength alone. Using only a simple tricycle, he casually passed Papyrus while he was driving a convertible which was likely moving around 40 miles per hour.
Boomstick: Rather impressive for a guy with no muscles, and though he goes down in one hit, he still took an attack from Frisk better than Undyne who was cleaved in half by a similar hit. In addition, Sans just walked away acting like that attack was nothing before turning to ash. Honestly, this guy is as stubborn as he is lazy.
Wiz: Though Sans is clearly a formidable opponent, he lacks the strategic mind of a skilled fighter, recklessly making attacks without considering the best opportunity for when to use them. This is probably due to most of Sans’ fights being erased from existence without his knowledge, and despite his incredible reaction time Sans becomes extremely vulnerable when he lets his guard down, which happens more often than you would think.
Boomstick: That's how Flowey managed to restrain him with some creepy looking vines, and how Frisk finally managed to win their duel with a surprise second attack. But, if you managed to be a threat to beings that can't be killed, you know that you're one heck of a bada**.
Wiz: Should he be the guide to freedom or the ultimate enemy, Sans always ensures that he will make his mark in the Underground.
Sans: It's a beautiful day outside. Birds are singing, flowers are blooming. On days like these kids like you... SHOULD BE BURNING IN HELL.
DEATH BATTLE![]
Deep within the Underground, a skeleton with a blue hoodie is seen sleeping in a yellow-hued room. His name is Sans, and he is waiting for a child to pass through the room so he may judge his actions and determine whether the child should be allowed to face Asgore. Suddenly, Sans hears something speed by and wakes up only to notice that the room has been cleaned in an instant with the floors waxed and the windows looking clearer than ever.
Sans: Interesting, I didn’t know the janitor here worked this fast… or that this place has a janitor.
???: Oh, there's no janitor here, I was just passing by and thought this place could use a bit of sprucing up.
A large octopus appears in front of Sans, the octopus is dressed as a typical tourist with a blue tropical shirt and a small brown hat, he is carrying souvenirs from the Underground with most of them being various treats such as Nice Cream and Spider Donuts to satisfy his sweet tooth.
Korosensei: And might I say this place is incredible, I’ve been everywhere on the surface, but who knew that there were plenty of wonders down here.
Sans: (*Who is this guy, I better do a quick background check just to be cautious*)
Sans takes a look at Korosensei and senses massive amounts of EXP and LV as if the guy had spent his whole life killing. Realizing the dangers of this creature, Sans knew what he had to do to ensure the safety of all monsters.
Korosensei: Well, it was nice meeting you, but I have a class to teach tomorrow so I best get going. The exit should be at the end of this hallway, correc-
Sans: Hey, I’m going to have to stop you right there it's not like a have a “bone” to pick with you or anything…
(*rimshot goes off in the background*)
Sans: But it's a beautiful day outside. Bird are signing, flowers are blooming. On days like this… Guys like you… SHOULD BE BURNING IN HELL.
Sans summons a group of bones to attack Korosensei from below, but the attack was too obvious and Korosensei effortlessly dodges it.
Korosensei: So that’s how it’s going to be, I guess I could use a warm-up before my students try to kill me again.
In the blink of an eye Korosensei disappears, puts his tourist outfit and souvenirs in a safe place and returns in his teacher’s outfit. Green stripes start to appear on his face to convey his confidence in overcoming the situation. Sans responds by revealing his glowing blue eye.
Korosensei: Now then, give me everything you got, and as a teacher I will “school” you in proper assassination techniques.
Sans: Not a bad pun, you almost made me regret doing this.
FIGHT!
Sans begins the fight by throwing a series of bones at Korosensei, but the octopus dodges each attack with his Mach speed. Korosensei continues to look confident as he raises his finger-like tentacles and waves it in a “tsk tsk” style.
Korosensei: While I applaud your effort, those bones are too slow to hit me, and I don’t see any anti-me material on them so there's no chance that you could harm-
Before Korosensei could finish, a laser blast hits his finger tentacles and completely disintegrates them. During Korosensei’s boasting Sans had managed to summon a Gaster Blaster and land his first hit on his target. Meanwhile, Korosensei examines his injury and starts to freak out.
Korosensei: WHHHHAAAAAATTT?!
Sans continues to fire Gaster Blasters at Korosensei, and the octopus takes hits from a couple of the blasters before he regains his composure and starts dodging the oncoming attacks.
Korosensei: (*What is with this guy? Not only are his attacks able to harm me, but I still feel the pain coursing through my body. I better find a way to stop him quickly.*)
Korosensei stretches a tentacle towards Sans in an attempt to attack him, but the skeleton effortlessly dodges much to the teacher’s surprise.
Sans: Too Slow.
Korosensei: (*Impossible! He can dodge my Mach 20 speed?*)
Sans immediately counters by summoning a bone from the ground which severs the attacking tentacle, before launching it at Korosensei along with some more bones. However, Korosensei was not phased like the last time and continues to avoid each of the bones.
Sans: Hold still!
Sans fires a wall of large, light blue bones at Korosensei, the latter of whom realizes he can’t dodge the attack and attempts to block it with his arms, which manages to succeed as the octopus does not take any damage.
Korosensei: Well that was rather anticlimactic.
While Korosensei, looks behind him to analyze the blue bones, Sans takes the opportunity to turn Korosensei blue and throw him towards the ceiling before summoning bones to land another hit on the octopus. To follow up the attack, Sans uses his gravity powers to violently throw Korosensei into several pillars before letting Korosensei hit the ground. Sans then prepares to finish the fight by placing two Gaster Blasters point-blank at his target.
Sans: Looks like I’m having fried calamari tonight.
Sans gives the signal for the Gaster Blasters to fire, but the attack is dodged not by Korosensei, but Sans himself who notices that the octopus had quickly turned the blasters around and applied makeup to them so that the blasters would look pretty.
Korosensei: A bit of mascara should really bring out those eyes. As for you, I hope you have more to offer because those attacks won’t be able to hit me again.
Korosensei takes the opportunity to regenerate his lost limbs and proceeds to attack Sans with another tentacle only for it to be dodged. Sans counters by summoning another bone, but this time Korosensei manages to retract his tentacle before the bone could hit. The onslaught continues as Sans fires waves of bones at Korosensei and mixes white and light-blue bones to keep his enemy under pressure. Korosensei effortlessly manages to dodge each attack and quickly appears behind Sans and attempts to strike again, only for the skeleton to dodge and take a huge jump back.
The octopus suddenly realizes that his body has turned blue, and anticipates that the opponent is about to alter gravity again. Sans does just that and increases gravity on Korosensei and fills the floor and ceiling with bones, however the force isn’t enough to restrain Korosensei who starts spinning his tentacles around like drills at attacks the nearby pillars to create platforms in midair for the octopus to jump on as he charges at Sans.
Once again, Sans dodges the attack and summons Gaster Blasters to attack from different angles. Korosensei avoids the blasts at with enough speed to make him appear as if he were in three places at once before hearing one of the blasters preparing to fire right from behind him. The teacher takes the opportunity to grab the blaster before it can fire and redirects it forcing the Gaster Blaster to destroy its fellow brethren. After destroying the other blasters, Korosensei tosses the remaining blaster at Sans who manages to avoid the attack and notices Korosensei coming from right behind the blaster to deliver another blow which Sans also manages to avoid.
Korosensei follows up his attack by running around and surrounding Sans with afterimages. While Sans did not seem to be phased by the doubles, he started to get worried about where Korosensei would attack from, and sure enough three tentacles came out from different directions though none of them were able to tag the skeleton.
Sans: Not bad, but I’ll have you singing the “blues” soon enough.
Sans retaliates by surrounding himself with light-blue bones, and Korosensei jumps into the air to avoid getting caught in the attack. Using the opportunity to his advantage, Sans summons a Gaster Blaster to hit Korosensei in midair, and successfully blasts the octopus into a wall. Korosensei immediately stretches out a tentacle to attack, but unfortunately misses his evasive target, but before Sans can counterattack, he is nearly hit by another tentacle coming from behind him. The skeleton then realizes that his target is stretching tentacles all over the place in an effort to restrict his movement. Sans continues to dodge the tentacles, but cannot find the opportunity to attack leaving him with only one option.
Sans: Hold it! Look, you seem like a nice guy deep down so how about you put down the tentacles. We can forget this ever happened and talk it out. It will certainly make my job a lot easier.
Korosensei considers the peace offer and proceeds to retracts his tentacles and walks towards the skeleton. Sans takes a sigh of relief and notices that the fight has caused him to sweat.
Korosensei: I’m glad that we could finally reach an agreement, and might I say you are quite the fighter, but if you don’t mind I would like to give you a bit of advice.
Sans: Sure, lay it on me.
Sans attempts to raise his arm to summon bones and incapacitate the octopus, but Korosensei had already anticipated the attack and grabs Sans’ arm before the attack could commence.
Korosensei: You should work on hiding your bloodlust. My students made better attempts at deceiving me.
Sans: Welp, it was worth a shot. Guess you like doing things the hard way, huh?
A pitch-black flash then covers the room in darkness, and once the lights return Sans had managed to disappear and in his place was a Gaster Blaster on the verge of firing. The sudden attack caused Korosensei to start looking scared.
Korosensei: Oh dear…
The Gaster Blaster fires, which knock Korosensei back, but the octopus quickly recovers and tries to figure out where his opponent has wandered off too. Before Korosensei can find Sans, another black flash goes off and Korosensei notices two waves of bones heading right towards him, he tries to jump out of the way, but fails to realize that he has turned blue again. Korosensei’s jump did not go as high as he intended and two of his leg-like tentacles are torn off by the bones, he tries to regenerates his limbs, but his body is suddenly thrown into a wall.
The octopus anticipates the next attack and jumps right before a group of bones emerged from the wall, only for gravity to change once again as Korosensei is thrown onto different surfaces and having to jump before he is attacked by bones. Korosensei is then thrown to the floor and makes another jump, but as he does a black flash occurs, causing two Gaster Blasters to appear next to him. Unfortunately, Korosensei doesn’t notice in time and he is hit from both sides by the laser blasts causing severe damage to his body.
Sans: I’m having a real “blast” right now, how about you?
Korosensei notices Sans standing right in front of him and dashes towards him for another attack. Sans dodges the attack with ease and starts summoning Gaster Blasters everywhere and aims each of them at his target. However, the attacks prove ineffective as Korosensei manages to dodge them until the constant laser blasts drive the octopus into a corner where a Gaster Blaster appears in front of Korosenei to finish the job. The blaster attempts to fire, but Korosensei quickly molts his skin and ensures the blaster before it can open its mouth.
Korosensei: Not yet, I can’t be killed by you, not while my students still have a chance.
With the little time he has, Korosensei regenerates his body and proceeds to attack Sans again. To no surprise, the attack misses and Sans causes another black flash and sends a series of bones from the ground and ceiling flying towards Korosensei. Now on high alert, Korosensei quickly checks his body and finds out that it has turned blue again, and adapts to his situation before using his Mach speeds to maneuver through the bones and charge towards Sans, who once again dodges and makes a black flash to hide while surrounding Korosensei with more Gaster Blasters, but the skeleton’s efforts are in vain as Korosensei avoids the blasts and attacks Sans once again.
Sans dodges once again and starts throwing light-blue bones at Korosensei to keep him still before summoning another Gaster Blaster, but the attack is to slow as Korosensei escapes the blue bones and redirects the blaster towards Sans, before using his speed to get behind Sans and deliver another blow. The skeleton jumps out of the way, but Korosensei stretches out two tentacles to pursue him forcing Sans to dodge once again. While Sans, managed to dodge the first tentacle, the second tentacles barely touches him leaving a small scratch on his cheekbone.
Sans: That was close. I might just have to use my special attack soon, but first let's see if you can survive THIS.
Sans turns Korosensei blue and throws him into the wall and summons bones from the wall only for Korosensei to once again dodge the attack, despite this Sans continues to throw Korosensei towards the walls, floor, and ceiling while attempting to stab the octopus with bones.
Korosensei: An identical attack, really?
Eventually, Sans stops throwing Korosensei around and starts throwing large bones at Korosensei only for the attacks to miss. The skeleton then throws Korosensei to the end of the Last Corridor, before inverting gravity and forcing Korosensei to fall towards the other end. To increase the pressure on his target, Sans summons large amounts of bones to cover every inch of the corridor turning it into a maze of death. Korosensei remains unfazed by this and flies through the bones without taking a scratch before landing on the other end of the corridor and jumping just in time to avoid more bones as they arise from the wall.
Continuing his assault, Sans creates a black flash to teleport Korosensei to a random point in the room before summoning bones from the ground and walls to hit the octopus. Korosensei barely has time to recognize his surroundings before dodging the attack. Sans continues to rapidly teleport and attack Korosensei which starts to agitate the octopus as he begins to have trouble anticipating where he will be teleported to and where the bones will come from. With one last strike, Sans manages to hit Korosensei in the heart with a well-placed bone causing the octopus to vomit yellow blood before being knocked back. Korosensei struggles to get up after the near-fatal blow, and Sans prepares to end the fight by summoning massive amounts of Gaster Blasters with the intent of firing them all at once.
Sans: You’re quite determined, but it takes more than determination to defeat me.
The Gaster Blasters fire creating a massive white laser that envelops Korosensei, but before the attack can kill him, Korosensei gathers his tentacles together which then start generating a white light of energy. While the energy is building up, Korosensei’s skin starts changing color varying between yellow, red, green, black, along with other colors.
Korosensei: If my determination isn’t enough then I’ll use my other emotions too. My happiness, my rage, my sadness, my love, my remorse. I’ll mix all of my emotions into the energy I need to take you down!
Korosensei then fires a massive white laser from his tentacles that starts to push back the Gaster Blasters. Eventually, Korosensei’s laser overpowers the Gaster Blasters and Sans is forced to dodge the energy blast as it destroys the Gaster Blasters along with one of the walls in the corridor. After both Korosensei and Sans were forced to go all-out, the two began to look exhausted, but Korosensei saw an opportunity to deal a finishing blow to Sans.
Korosensei: It looks like you won’t be able to dodge anymore. Let's end this once and for all.
Korosensei flies towards Sans to land one last attack, but the skeleton’s eye starts to glow and the octopus soon finds himself back where he started. The octopus then attempts to make another attack by stretching his tentacle towards Sans, but once again the attack fails as the tentacle is brought back to its original position.
Sans: Do you like that? Its my special attack. Sure, I’m not really attacking, but neither are you which means you will never be able to kill me.
Korosensei: So you plan to end this in a stalemate? Not a bad idea, except I haven’t shown you all my tricks.
Sans becomes concerned with what Korosensei said until suddenly he felt something pierce through his body, the skeleton turns around to find that one of Korosensei’s tentacles has emerged from beneath the ground and has successfully managed to impale him.
Korosensei: My tentacles can burrow through the ground with ease. Its perfect for assassination, but I needed to find the right opportunity to use it, and once you started keeping me away I knew you couldn’t dodge this attack.
Sans: So… guess that’s it, huh? See you in hell, murderer.
As Korosensei removes his tentacle, Sans’ glowing eye begins to fade as the skeleton becomes a lifeless corpse. Feeling remorse for having to kill again, Korosensei gives his regards to his latest assassination victim.
Korosensei: You were a worthy adversary. May you rest in peace.
K.O!
Sans’ body disintegrates into ashes while Korosensei gathers up his souvenirs. Suddenly, Frisk enters the room and tries to kill Korosensei with a knife, but as soon as he attacks Korosensei replaces the knife with a flower from Asgore’s throne room and leaves the Underground before the child could react. Frisk is left confused about who the mysterious octopus was and how he failed to kill him.
Results[]
Boomstick: I feel a great disturbance, as if millions were being silent and suddenly screamed in rage.
Wiz: Calm down Undertale fans, this fight was a lot closer than you think. Sans’ unpredictable arsenal gave him plenty of means of keeping Korosensei on edge and their magic properties allowed Sans to harm Korosensei’s antimatter body.
Boomstick: And Sans had no trouble dodging attacks from the octopus since he dodged attacks from Frisk who is clearly faster, but superior speed wasn’t enough especially when Korosensei’s intelligence and super senses helped him anticipate Sans’ next move. Even if Sans could land a few good hits, Korosensei could simply undo the damage with his regeneration.
Wiz: To be honest, both Korosensei’s and Sans’ abilities are so well suited for fighting each other, that it was difficult to determine who would land the killing blow first. However, one key factor tipped the scales into Korosensei’s favor: experience. Korosensei has spent years perfecting the art of assassination to the point where he can best entire armies giving him far more combat experience than Sans, who had most of his fights erased from exsistance, except for the one he lost.
Boomstick: Not to mention, Korosensei is pretty good at figuring out other people like how he helped each of his students with their individual problems, given enough time he could easily deduce Sans’ fighting style and weaknesses. It didn’t even matter that Sans had speed advantage, since Korosensei dealt with plenty of opponents that tried to overcome his Mach speeds, like his apprentice the Reaper who was basically a faster Korosensei.
Wiz: While Sans could certainly dodge anything Korosensei can throw at him, he has been defeated by sneak attacks in two different timelines. Given enough time, Korosensei could use his assassination techniques to catch Sans off guard and land a fatal blow. Despite being fast and unpredictable, Sans couldn't keep up with Korosensei’s endurance, abilities, and experience.
Boomstick: Looks like Korosensei got his happy ending at the end of this Under-”tale”.
Wiz: The winner is Korosensei.

A mysterious figure appears behind a cloud of dust. When the dust clears it reveals a man with a mechanical arm and a cowboy attire. The scene cuts to another man with a blue sweater and an odd piece of headgear as he holds up a revolver.
Mista: We'll end it right here, right now. Time to bust a cap in his mouth!
