Prologue Part 1

Megalovania

The great Judgment Hall is silent as death, for death is everywhere these days, seemingly polluting every corner of existence. The whole of the Underground wreaks of death's unholy stench.

So many have been slain, no that is not the word...Yes, slaughtered would be a more appropriate term. There was no nobility in their actions, no mercy.

The human... The thing that is supposed to be human was given judgment ever so long ago. It was clear their killing spree would never end.

Relentlessly, they hunted down and butchered every last monster in the entirety of the Underground. Of course the monsters tried to flee, flee the streets of the city the murderous being now stalked. Unfortunately, there was nowhere to flee. The barrier prevented them from achieving any sort of escape onto the surface. They were to no surprise killed, just as every other innocent soul was.

In the end, this place provided no safety to anyone. Even the great warrior and heroine Undyne had failed to stop them. If the captain of the Royal Guard could not save the citizens of the Underground, who could? The entire city was thrown into a fit of fear over the death of their saviour. Now, there is no one left to panic. A sad yet grim thought of what had befallen those outside this hall. Of course, there is always a chance for survivors. That is unlikely considering the human's persistent quest for genocide. Anyone who has survived the initial killing is probably dead regardless of whatever they did to hide.

The people of the Underground have all stood their ground in the face of this being. They tried to fight, but even their all couldn't even faze them. They consumed the monster's souls, absorbing them to become stronger. As they did this, their LOVE increased, the EXP they gained fuelling this expansion. Execution points are all they seemed to lust and each kill increased that addiction, each kill increased the human's Level of Violence. At this point, it is a heartless demon, ravaging the Underground creating only death and destruction. Nobody knows the real reason behind this, but it is clear it brought only ill intentions.

Oh, how so many have fallen to their strength, their Determination. That is the scary part though. It never did give up no matter the suffering, no matter how many times it died they kept coming back. They killed Muffet with no regard to her now motherless children. They killed Toriel despite her love for them. All she wanted to do was educate and care for them and instead she gets stabbed and butchered. Pure evil right there. Oh, and let us not forget the friendly, loving game show robot Mettaton who they killed with equal disregard. The fans were next.

That isn't even the worse of it. At least Undyne gave them a run for their gold, but even she couldn't stop them forever. They slaughtered her, watching her melt in pain, red eyes wide with glee. They proceeded to hungrily tear through her ashy remains in search of every last EXP. It was disgusting, wretched and evil. How could any sentient creature be so cruel, so bloodthirsty? Why would they abuse their powers in such a way to kill every poor citizen of this place?

It is genocide, simply put. No meaning, just mass killing, all on the behalf of a single individual. One who has no remorse for the weak or innocent. No respect for those who led them or fought for their safety in the other timelines. Only hate and greed exist for them. Selfishness and the need to control rule their thoughts.

Now men, women and children are all dead because of this single human, so impossibly determined to steal their EXP and souls. And they will stop at nothing to collect every last point. They will regret it though, they very much will when they enter this room. And only he has a chance to halt the coming arrival.

His name is Sans, Sans the skeleton and these are the thoughts that are racing through his head as he waits.

The murderous, psychotic freak killed his brother. Out of all people, why him? He is the nicest person down here and the human just stomped his head into the ground without remorse or thought. Brutal.

The human is going to pay. So dearly will the human beg for mercy when they meet him. They will beg for forgiveness, beg him to forgive all the deaths they caused. He wouldn't...ever. He would avenge the deaths of his friends and family, bring them the vengeance they deserved. These images plague the big boned skeleton as he awaits the human's arrival.

He knows he is the last thing preventing the human's victory. He is the only hope left, the only thing preventing total annihilation of the monster species and this realm.

I know why you won't die, why you won't give up kid, Sans thinks with his bony hands clenched into hardened fists within his blue hoody's pockets. The truth behind their unstoppable advance was quite simple really. The determination they possess basically allowed them to "SAVE", the god-like ability to create a save file that they could return to when they died. This could be done as long as they had enough determination. The problem was, the human never did lose determination. They just keep going, no matter what.

Undyne the Undying killed them countless times, yet the human still triumphed in the end. Sans knows Undyne was on a far lower level than him though, despite her warrior training. After all, he is able to do some amazing things like shortcuts and dodge any attack. He is going to use these powers to teach the genocidal monster a lesson in pain and defeat.

His strategy is simple: kill the human until they gave up. Once they give up, their determination will be gone. Without determination, they can't load their save file. In that case, they will die for good. Problem solved.

The plan doesn't help shake the anxiety out of him, the feeling that he will fail and die like all those before him.

Stay determined Sans, he thinks to himself rigorously. He pauses mid thought, a wave of depression taking over. Why should I? Everything will reset anyways if I lose. Maybe then I can be happy with my brother again.

Sans digs around in his hoody pocket and weakly pulls out the red fabric of his brother's red scarf. In anger he clenches it in his fist, tears running down his face. The sadness rolls in like an unstoppable tide, none to different when he saw his brother's dusty remains strewn in the snow beside this very item.

That kid is going to die hundreds of times if I win or not, Sans thinks as he stares down the hall. That dirty brother killer will never pass me, even if I must stand here for eternity. He pauses and smiles. And I'm going to enjoy every second of it. Every ounce of misery, hatred pain; I'll indulge myself in it.

"Wow," said Sans. "A real smile. Haven't done that in a long time. Never would have thought it would be the idea of hurting another person to." He takes a brief look out the window before setting his eyes on the hall once more. A long sigh exits between his big teeth. What have I become?

The hall has yet to offer the slightest sound of interest. All he can hear is chirping birds. At least they didn't murder the wild life. That's something right?

Sans looks down and kicks out his left foot. He is wearing slippers of course. It is either that or runners, but slippers just made more sense. To him at least. They are cosy.

"Of course I'm wearing the usual," he muttered lowly. "I'm too lazy to find a better style." He knew it isn't just that though. It is the fact the clothing felt just right. The black shorts with white stripes fit his big boned body perfectly and the blue, plush hoody is very comfortable. It caused an intolerable itch though. The white undershirt helped, but never entirely solved the problem. It held his ketchup well. He needed it. Teleporting takes lots of energy.

Everything would reset if he lost and Sans was mighty aware of this. It's what drops the hope he holds in his soul. This isn't the first time the consequences of a reset crossed his mind. The idea everything will start over, everything he worked for erased in the process. He would be forced to start back at the beginning from scratch. Then, he would proceed to repeat the same tasks over and over for eternity. It is the reason he is so lazy. Why do anything when it is impossible to get anything done?

Then you add the fact that this has happened seven times over. The first time went well actually. Chara was nice and did not reset, or so he was told. He was not alive that long ago. But they died of illness and then Asriel died, two horrible deaths in a single night. The other six human's who came after caused a fair amount of trouble, doing a neutral route, but also dying because their determination was not great enough to sustain their souls after death. So, the resets caused by those humans never caused much trouble. Then Flowey came and really started screwing things up. The flower compulsively reset, the times he did so exceeding that of all six previous humans combined. Now this Frisk character is just adding onto this.

Ever since that flower arrived things have been reset non-stop, thinks the skeleton. They never did stop resetting and this human, well...the new being with the reset would only repeat Flowey's endless cycle. Same problem caused by a new person. The flower is a nightmare, a soulless creature injected with determination. The only thing keeping Flowey alive is the will to live, the need to see every outcome, and the power to do so as he pleased. Until the human fell down and threw all that out the window. The human has more determination than any other thing in the Underground and so they now had the ability to reset, the flower losing his powers in the process. Flowey is the only monster in the Underground with determination besides Undyne, but Flowey is sustained through the substance itself. Therefore, the flower is stronger than her. But not a human. Their souls are just too powerful.

Sans also knows the flower is working along side the human and that he is the most likely reason they are committing their current actions. Like Flowey, they have to see every possible outcome. They are compelled to. Doing pacifist repeatedly wasn't enough. They want to see all outcomes because they can and they will. Simple as that. The curiosity led to blood crazed murder and insensitivity to those lives they once cherished. Remorseless mass murder was the result. Being stuck in the same timeline really did drive people insane, didn't it? What does that say about me? That is a question he preferred to never know the answer to.

The reason for reset in its most fundamental state makes Sans question its existence as a whole. Why was it needed? Why did it exist? The flower never did reveal what he fully understood to him, nor to his brother. Often, he wonders what the truth is behind the timeline jumps and the whole resetting conundrum.

Only one person could ever understand this, Sans thought as he stares onwards. Oh Gaster, if only you were still around to help us. We could use it. The former Royal Scientist was deeply involved in the whole timeline thingy, never letting on how much he truly understood. He was always saying it was just a theory or that more time was needed.

W.D. Gaster was tasked with breaking the barrier once he finished the core, a task that would lead to the determination experiments involving the souls of fallen humans. He knows his companion learned about SAVE files from these projects, calling them "a by-product of a soul's strength and perseverance."

This was all abruptly ended when Gaster fell into the core, shattering his soul across the fabric of space and time. If he still somewhat existed, nobody knew. They have no means to find him in his current state.

Following his death, Asgore chose Alphys to become the new Royal Scientist, continuing Gasters' experiments. Before the whole core incident though, he gave Sans a decent clue as to how the reset worked and how Determination is responsible. It is the only reason why what is happening now made the least bit of sense.

Sans thumped his foot down on the hall floor in sudden rage. Determination. Why must human's have the most powerful of souls? Why? They don't deserve that kind of strength. It has brought death and nothing else. A dark thought struck his mind at that very moment. What if that's the reason they are so strong?

With a sigh Sans looked out the lovely paned windows. The empty city stared back, not a sign of life or activity amongst it. The only movement is from the wind, the underground current blowing a fine mist of white powder across the land. The remains of monster kind. Disgusting.

He snaps his head forwards, gazing down the long hall, pillars on either side. The endless repeating pattern of paned windows and stone supports seem to loom on forever. The square tile floor is brightly lit by what little light entered through the windows, giving the floor a fancy glare. Above him loomed the high ceiling, arching in a curve to create a rounder look. The room over all is perfectly clean and he assumed it would become quite the mess in the near future.

Sans took what little time he had remaining to remember the other timelines, the ones where Frisk was the good child they were supposed to be. Not...this.

The memories are faint and distant. Remembering previous timelines is by no means easy. He knows quite clearly that the child had been the most harmless thing in the Pacifist Route. All those times they laughed, all those times they spent together happy. They were a family. Not just him, but Papyrus, Undyne, Toriel, everyone. They were family and Frisk was at the centre, the child who wanted only love. Real love, not that violence crap. They had fun and lived happily ever after.

But now...They are merciless, a killing machine. How can someone so innocent become such a monster? It made him question if the human really is aware of their actions. Did they know about this? The fact they could reset meant it has to be Frisk, but why would they kill all the people they loved? Why Frisk? Why must you do this? Is it just because you could? The skeleton ponders, holding back what little tears he has left to give. Pappy already took the majority.

No Sans, stop thinking about it, He scolds himself, shaking the thoughts out of his head vigorously. You have to kill them. If you do, Flowey will reclaim his place and everything will be normal once more. You'll have your brother back and everyone else. All you have to do is break their determination.

Sans now finished with his thinking stares at the flickering yellow Save Point patiently awaiting the human's arrival. As he does, the ball of dread inside him grows only stronger. He feels his self esteem drop greatly, but puts on his best smile for the human when they make it here. Don't want to disappoint our guest now, do we?

Sans is well aware he hasn't fought in a long time. Actually, I can't remember the last time I did? That much is true. He never was a fighter. He just likes to lay around and be lazy, do nothing. In fact, fighting is the opposite of that. It made him being so utterly powerful ironic. But now he has a reason to fight and the human will see just how deadly a friendly guy like him can be in cold rage.

The sound of the save file going off echoes down the long hall, announcing the presence of his visitor. They are finally here and the forced smile becomes real as it widens further, a thrilling burst of magic energy drilling its way through his bones. Oh it's time.

From the halls opposite end approaches a slumped figure, crawling out from the darkness like some festering bug from under a log.

They radiate a field of hatred about them, a lust for death and murder, for pain. Their torn blue and purple striped clothes and shorts are stained with their own blood mixed with that of the countless monsters they have gutted. Their pale skin is caked with the ashes of innocents and they wear a blank face with a straight mouth, eyes concealed by the shadow of their bangs.

In their right hand a glimmering knife is held, brand new and so clean that Sans can see his skeletal reflection in it. They twirl the knife in their hand, the light from outside playing along its smooth surface. They may not have an expression, but the skeleton knew they had a great deal of emotional attachment to that weapon just from their behaviours. The sheer power of it is overwhelming.

Sans observes the demonic child as they walk up to him in their odd offset gait, each step fluid and precisely calculated. Occasionally the child would twitch their head and lick their lips. The fact that this is just a youth is quite horrifying. It sure as hell didn't look like a child covered in the remains of his friends, but no matter what he thought it didn't change the facts. It never will and never would.

Sans observes them closely, hands still in his pockets and smile wide upon his face. What tricks do they have up their sleeve? He wonders as his tiny pupils dart around inside his eye sockets. Without a doubt there are more items than a simple knife in that kids inventory.

The human makes its final slow step, the final clack of bloody shoes slapping against the ground entering Sans' ears. The human has the knife in a death grip, already prepared for the fight. They stand mere feet away from him and are unimpressed by his smile. The determination they possess is indescribable. It was sheer and brutal, inspired by hunger for souls.

With the idea that this is only a child embedded in his head Sans thinks, Better get this show on the road I guess. Morbidity plagues his every thought. Today is not a bright day. Regardless of all the good memories from the other timelines, he can't help but stare into the human's concealed eyes with pure hatred. Every bone seemed to be melting with anger. Despite these inner feelings, he keeps his cool.

The human has equipped a heart shaped locket around their neck, a detail Sans picked up only when he focused in on the neck he so wished to snap. That locket though...No, it can't be? How? Only one person could possibly know.

"Chara," mouths Sans as they approach, the human's form flickering to that of the rosy cheeked child with red slits for eyes and a thin smile. The ethereal figure wears a green sweater striped with yellow and brown shorts. The only similarity between them and Frisk is the brown hair and shoes. Before Sans can even respond the image flickers away like static, leaving only Frisk behind. I think I can see what's going on here, thinks Sans. But there's no time to piece it together.

Knowing the fight is going to begin Sans begins to make one final attempt to reach out to the human, to the Frisk he remembered, the good kid he thinks of as family. "Heya, you've been busy, huh?" He says in his low toned voice. The human just ignores him.

Sans briefly avoids eye contact before continuing. Staring at that blank face was starting to get freakish. It makes him feel the chills. "So, I've got a question for ya; Do you think even the worst person can change? That everyone can be a good person, if they just try?" A evil grin forms on the human's face and the skeleton's smile twitches.

The human erupts into full blown laughter, a cold youthful laugh that echoes off the walls. Sans wants to reach and snap their neck, crush their soul into the ground and watch it fragment endlessly for eternity. The sick bastard will pay.

After a couple of seconds the laughter fades and they give the lightest of head shakes. Sans can't help but laugh himself. The human seems a little thrown off guard. Good, he was making a impression. "Heh heh heh heh...all right." He briefly pauses as he searches for the right words. "Well, here's a better question; do you wanna have a bad time? Cause if you take another step forward, you are REALLY not going to like what happens next."

The human snickers and takes the step. Sans knows he has failed and that they would fight to the death. "Bring it you big boned comedian," hisses the human as they toss up their knife and catch it as gravity brings it back down.

Sans takes a deep breath as he remembers Toriel's words. "Welp, sorry old lady. This is why I never make promises." The room grows dark as the they enter the fight, the soul of red veined with black materializing before the human. Their face is now blank as ever. Focused.

Sans closes his eyes and absorbs the ambiance of his surroundings, listening to the sounds around him. Collecting his inner thoughts would help him gain focus. "It's a beautiful day outside," he says. "Birds are singing, flowers are blooming. On days like these, children like you..." He opens his eyes to reveal blank sockets of eternal rage. The death of all those he loved run through him as he speaks the final part. "Should be burning in HELL!"

With a flash of light Sans's right eye sparks to life with a blue orb of magical energy burning with the intensity of a miniature sun. It sparks and flickers wildly, no control being had. The human is for the first time nervous, aware that this fight might actually be a slight problem. He snaps his fingers and his song begins to permeate the area. This megalomaniac was about to get it. "Now this is my jam."

Sans whips his hand out of his pocket and raises it high, the human being thrown into the air, soul dark blue as a field of bones shoots up beneath them. They manage to hover just long enough as their soul turns red. They slowly float down like a leaf and gently land.

"That's the easy part," Sans says as he throws a torrent of bones at the human as the armed projectiles appear behind the skeleton. Hands in his pockets, he manipulates their movements with his mind. "Let's see how you handle this."

The human smiles at mass of white lines descending on them like a hoard of angry bees. They scan the attack with cold calculating thought and find a way to thread the needle. They notice a curved path through the bones and at the last second sprint forward in a blur.

The human dodges and manoeuvres through the path as bones shatter around them. In no time at all the last bones hit and they slide to a stop and flip back up to their feet. They smile, hardly fazed. "Easy."

Sans shrugs with a wink. "Hey, don't judge me just yet kid. Let's see if you can survive this again." With that another field of bones appear and are launched in a flurry of white. They whistle down towards the human who is most unimpressed.

The human ponders the attack and once again zips their way through unscathed, that is until the half way point. At that moment everything changes as the bones start to fly in side ways. In a panic they try to dodge, using various acrobatic moves to evade the projectiles. Nearing the end the swarm is so thick they are forced to use their knife to slash them out of mid air. Red gashes begin to appear as the human takes the fight to the attack, but even that isn't enough. Just as the last dozen or so come flying in one sneaks in through their peripheral vision and scores a direct hit on their heart. Not the soul hovering in front, but rather the organ the skeleton lacked.

The bone impaled them, blasting a clear hole through their body. A spray of blood is ejected from their back. The red liquid splatters onto the floor behind them as they struggle to deflect and dodge. It is leaking profusely from the sides of the hole, soaking into the shirt. They squint in pain and gasp.

That isn't the last one though. Three more get past, two hitting the right lung, the human coughing up a red mist in response. They fall to their knees only to receive an extra to the gut, gore slapping onto the surface behind them.

Sans can't help but wince. Damn Frisk, I'm sorry but it has to be done. Frisk falls onto their side, the blood now saturating their clothes and pooling on the floor in a glimmering puddle. I said I would indulge myself in this, but this is just awful. I never would have... Sans pauses and glances down. What would Papyrus think of this? What would any of them think? Evil or not, their still a kid. What have I become?

Frisk, in a final fit of effort manages to rip out the bone in their chest, a sickening sound of relief and pain exiting their mouth. They clasp a hand over the wound, but it does nothing to stem the flow as the sticky fluid flows it's way over their fingers, adding to larger pool around them. The human with a bloody laugh shakes their head. "Oh, do it again please. The pain is wonderful, oh the determination I feel it crawling through my skin."

Sans ignores the human's insane rambling and asks his own question. "So, how does it feel to get dunked on?"

They laugh. "Your just as dumb as Undyne. Killing her was a joy, to finally get revenge after all those resets. In fact, if she were any weaker I would love to reset over and over just to feel the glee of killing her, just to see the blood saturate the soft ground."

Sans can't help but gag at the purity of the human's evil. He quickly recovers, disgust replaced with rage. "What in the hell is wrong with you!" A Gaster Blaster, a magical weapon in the shape of a skull begins to charge its laser to his side.

The human doesn't respond as their face goes blank, the blaster releasing a ghostly beam of blue and white energy that envelops the human, evaporating them into subatomic particles. The Gaster Blaster dissipates and a single corrupted heart rises, cracking in half and shattering into several red shards. Sans shakes his head with a grin. I take it back. I will enjoy this.

The human reloads their save file and Sans feels what little energy he used restore itself. They make their approach once more, ready to do battle. Hands in pockets, he waits. He knew deep down though that this fight is far from over and that he will start to become predictable.

Despite the circumstances, he can't help but taunt the human. He wants them angry, he wants them to quit. But it was fun too, so he was going to do it.

Sans shifts his eyes and nods as the human stands ready for combat once more. They are clearly enraged. The blank face wasn't so blank anymore. "Heya. You look frustrated about something." He pauses and the human twitches. "Guess I'm pretty good at my job, huh?"

The battle starts up again and it goes as it did last time. However, the human doesn't get hit. Not once. Not only are they learning, but they are learning fast. It was going to become a problem.

Frisk darts around with speed even Sans himself finds impressive. They sure are quick. He follows the dodging techniques carefully, trying to develop a counter to their movements. They cut away the bones in a blur of steel and dash in what could be a shadow. Intimidating, but not a problem he can't handle.

Sans moves his arm and summons four Gaster Blasters, all of which circle the human. They begin to charge, but the human is able to dodge the beams with a powerful leap.

"Hmmmmmmm", hums Sans as he rearranges the blasters into a square. They fire and the human plays smart, not moving as they create a fence of lasers around them.

The skeleton now raises the blasters and morphs them into two larger variations, both which circle the human. They charge and launch their ghastly beams, the white energy chasing after the fleeing human as they jump and slide around them.

Knowing this is a fruitless attack they are dissipated and the human, not the least bit tired, grins.

Sans roles his eyes. "So you survived my first attack, huh." He glances of to the side briefly before resuming eye contact. "Welp, there's a lot more coming your way."

It was the human's turn though and they enter a full blown sprint, eyes a boiling pot of insanity. They slash the knife at Sans and hit...nothing? A miss? The human flips forwards to recover from the miss and turns around to see the skeleton standing behind them shrugging. "What? Did you really think I was just going to stand their and take it?" The human frowns slightly and lunges again only to fall flat on the floor where Sans was previously located. They get up and turn around once more.

Sans is simply standing. They have no time to react though. The skeleton is already mid-swing and his fist comes down right on their nose. Direct hit! A sharp crack is released from the breaking bone. He feels their nose flatten under his fist, blood launching up from the wound. The human stumbles back and wipes away the blood gushing from their flattened nose with the back of their nose. Sans doesn't bother to remove it from his fist.

"Walked right into that one kid," taunts Sans. "Or I guess you could say turned into." The human twitches and flickers to Chara who gives him a bone chilling smile before reverting to blank Frisk form.

Frisk attempts another running start, knife raised high as Sans struggles to understand how they can persist. How can they stay so determined? The determination needed would be of astronomical proportions. Then again, they have the soul of every monster in the Underground, so the true extent of their powers are debatable.

"Your not gonna get close this time," Sans says as giant bones are thrust through the dark floor in a clap of thunder. The ground shakes and Frisk barely manages to jump, but to counter their heart flickers to that of dark blue and gravity takes toll and down into a field of white they fall. But the human was by no means stupid. They manage to handstand on one and flip onto the next. In seconds they're making a full sprint across the obstacle.

Damn it, I thought that would be a killing move right there, Sans thinks with inner frustration. Welp, time to mix things up a little. With this in mind he begins to make them bob and move. The human slows down to maintain balance, but fails to show the slightest sign of falling.

Maybe the problem is quantity, not quality. More bones erupt from the ground. Debris rains all around and the human continues their parkour. Note to self: More makes it easier on enemy in air. By then it's too late to do anything else. The human jumps off the final bone and flies down, knife aimed straight for the skeleton's chest.

"Nope," says Sans as he teleports to the side. The human makes a quick roll recovery, knowing he has moved. They lash out blindly to the side and look up to see him staring down at them.

"Heya kid, you don't look to good." The human whips the cold steel blade upwards. By then it is to late though. The skeleton is suddenly beside them, foot connecting straight with their rib cage. The cracking of more bones fills his ears and a trickle of blood runs down the human's lip. One of the ribs must have punctured a lung. Not like he cared. Good.

The human weakly attempts another attack, a pitiful slice that he easily slaps away. The knife is knocked out of their hand and onto the floor. He levitates them with a quick gesture and with the extension of his arm to the right the human flies to the right, hitting a stone pillar with a thud.

Sans watches the human weakly rise, legs wobbly. "Legs feel a little like jelly don't they?" He shrugs. "Honestly, your pathetic. I have a single hit point and can do only one damage. How can you not beat me?"

Angry, the human charges with strength anew, swiping the knife in rage. Just what he wants. The human is ready for bones to emerge from the ground but not the ceiling. This is a weakness Sans is willing to exploit.

The attack comes so suddenly the human doesn't even have time to react. A large bone scores a immediate hit through Frisk's gut, punching a dodge ball sized hole through them.

The human now lays on the ground, pinned by the giant bone that impaled them wearing an expression of shock that Sans would happily pay his tab at Grillby's to see.

Frisk lays unmoving, deep breaths sending out swaths of blood. The majority of it is pooling around them, just like last time. The pain is evident in the face of the human. "Pain is good. I'll kill you Sans. Your soul will be mine. Bring it. I'll just keep reloading my save file. You can't go on forever." The human gurgles a raspy laugh.

Sans considers letting the human sit there and suffer. They deserve it. It's revenge, perfectly acceptable revenge. Yet...Sans closed his eyes and squints. They are Frisk. I-I can't just torture them. At least they be killed quick. I have no right to brutalize them this way.

Sans sighs and advances on the human, ready to give some pay back. His magical blue eye focuses on the indigo heart, ready to pop it like a balloon. The human turns to Chara who wears a smile as the skeleton looms over them. He sets his foot down on the heart as the demented child braces themselves for the pain.

"This is for Papyrus!" He shouts as he puts his weight into his foot, crushing the heart. Chara laughs as they fade, the heart shattering into a million blue pieces under his foot. It disappears and the sound of it shattering fills him with a sense of achievement, of progress. Why did it feel so good to crush their soul? He once again awaits the human's arrival, doing his best to mentally justify his actions.

A very angry human stumbles out from the darkness, clearly unhappy about the current circumstances. Each step possesses a alien fluidity, a grace that seems to portray innocence. They flickered to Chara often. It seems the more enraged they became, the more prominent Chara will become. A realization finally hit Sans. What if I'm just making them stronger? Is me defeating them just giving them power? Regardless, there is no time to debate. The human now in Frisk form is on the move, slashing their way through hastily summoned bones.

The fight proceeds and ends with a direct hit from a Gaster Blaster, instantly shattering the soul. "Here's a present from Toriel!" Yells San in rage as he kicks what ashes of the human remain before fading away. His blue eye flickers with power.

Once again the human reloads. The human is gaining knowledge on his attacks. They are learning and are still very much determined. If they do not give up soon the fight might actually become dangerous.

They fight, the human now getting further, but not by much.

"I personally don't think it's okay to kill every living creature you come by." Sans shrugs with his wide grin pasted on his face. "But hey, that's just my opinion."

The human jumps forwards and dodges a burst of bones, lashing out with the sharpened steel. Sans teleports to the side and levitates them up into the air. They squirm, kick and struggle, yet the skeleton's magical telekinetic grip doesn't flinch in the least.

"Your not accomplishing anything by doing this kiddo." Sans gives them a menacing look. "Why do you do this? Do you do it just because you can or for power, or what?"

Frisk flickers to Chara. "Many reasons," they whisper as Sans tightens his magical grip.

"Such as?" He persists.

"None of your concern," barks Chara as they revert back to Frisk.

"Fine, we can continue to fight I guess." He swipes his hand across his chest, the human following the movement. They hit the right pillar with a loud crack. Sans throws them against the left wall. Progress, but still alive. He slams against the ceiling, throws to the floor, bashes them against the walls, and repeats. Finally, the soul of the mangled human shatters and the bloody stains fade from the walls.

Several more rounds follow, all leading to their death no matter how hard they try.

At round ninety-nine Frisk has something to say. "This time your going to get it." There was no anger to be found in the words, only cold hearted meaning.

"Whatever kiddo," dismisses Sans. "I'll kill you until you give up." With that he creates a storm of bones composed of both blue and white. They rain down, but all fail to land a blow. Instead, they shatter against the floor uselessly.

Next come the Gaster Blasters, all of which fire their ghostly beams. Misses, all of them misses. The human is simply too quick and precise, flipping of walls and darting from one place to the other. Their movements are just too sporadic to track. The skulls have failed once more.

Sans continues his assault and pressures their skills further as bones jut through the walls, forcing them to jump and duck. They successfully do so, the attack having no effect.

"Try and hit me," beckons Sans as he eyes the human with his one blue fiery eye. The human obliges, sprinting with the blade poised to strike. They slash it wildly, but he is too quick, every attack missing as he teleports side to side.

"Wow, you really are slow aren't you," says Sans with his big grin. The human lashes out, swiping the knife upwards only to realize he is now behind them. This time they pump their legs down and flip right over him. With the skeleton now in front of them, they swipe and miss.

"Little too late, bud." Sans now goes on the offensive, his bony fist flying straight into the human's gut. The satisfaction gained when he feels it sink into their chest is fulfilling. Air exits the human with a loud off as the pain stuns them.

They're launched back several meters and are sent forwards again as Sans hits from behind, teleporting to where they would land just in time to hit them again. Injured, they skid to a stop on the floor. In their weakened state they have no means to resist his telekinetic powers. He easily lifts them into the air.

"Give up will you? This is pointless. You can't win," argues Sans. "I've killed you ninety nine times so far." The human manages a weak nod in their weakened state. Is that tears in their eyes?

Sans blue energetic eye perks. This is...Unexpected "Really? I guess that's logical. Ya know, I wasn't even using my full power there. But, if you want me to spare ya..." He pauses a shrugs. "I ain't got no problem with that."

Sans takes a deep breath as memories of all the good days with Frisk come rushing back. "I know you didn't answer me before, but... somewhere in there, 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? C'mon, buddy, do you remember me? Please, if you're listening, let's forget all of this, ok? Just lay down your weapon, and... well, my job will be a lot easier." The human would accept. He knows they will. They are too weak to continue on fighting. He would love to spare Frisk, but their is a slight trust issue here.

Frisk lets the knife slip from their grip and clatter against the hall floor in despair. They smile, knowing that they may finally have done something right. This wasn't the cold smile of a murderer, no, this was Frisk. The one he remembers, his friend and family. Not the dirty brother killer.

"Please give me mercy," the human whines as tears of realization run down their face. They sob and cry, the crimes they committed rushing back to them. "S-sans...help me please. They...I can't." They shake their head mournfully. "Oh god, what have I done? Why did I do it? W-w..." They degrade into full blown tears as they cry. "I just want to g-go h-home... I-i'm s-s-so s-sorry.."

Sans isn't sure of what to do. He swears this is the original Frisk, not the psycho murderer. Yet... Can he really trust them after all they did? Are they that deserving of forgiveness. In all honesty, he felt bad for the human. They are just a child after all, and if his theory was correct, possessed by Chara.

"Sans," Frisk says gently as tears of regret paint their face. The pain seems too worsen with every word. "Please, can we be friends again? I can reset and fix everything. I remember all those times, the good times, just as clearly as you."

He is about to mercy them, to become friends once more. The last words really drill it in. It is true, they can do a Reset and start from the beginning.

Then the hatred returns stronger than ever. They can't live though, especially with Chara inside of them. Frisk or no Frisk, they must perish.

Sans winced as his morals conflicted. They are so innocent though. I can't just kill them like this. What would that make me? Do I really want to drop to their level? I-I... With all his might he tries to supress the rage, tries to look at the bright side. I'll kill them. I just need to control my anger.

He can't.

His soul flares with anger as he reflects back on all the crimes committed by the human. It has to be a lie, a trick...right? It can't be Frisk. It is all Chara. And if he accepts he is sure they will stab him in the back.

The memory of the human crushing his brother's skull under their foot came back, that innocent face being ground to dust by the emotionless freak that was once his friend. It would take one hell of a psycho to kill his brother. He was goofy, funny and lovable in every way. He never did fight well, or liked to for that matter. He was just a peaceful puzzle maker wanting to be a Royal Guardsman... who kept faith in the human even as he took his last breath. Sans would have argued his faith may have been misplaced, but what was the point? Everyone is dead now. It didn't matter.

Oh, but the human doesn't care for all the souls they killed and consumed. And now here they are, begging for his forgiveness. It was pathetic and quite a low blow thing to do. After killing Papyrus they happily continued their bloody crusade, staining the snow with the blood and dust of every monster they came across.

Sans knows not the extent of the damage caused by the human. That day he spent weeping over his brother's remains, promising that he would do everything he could to avenge his brother and everyone who suffered at the hands of this child. He refused to have the entirety of the Underground consumed by some demonic human. Knowing that demon was Chara made it all the more serious.

"So you're sparing me?" Sans says with a forced smile, trying with all his might to conceal his inner feelings. "Finally. Buddy. Pal. I know how hard it must be... to make that choice. To go back on everything you've worked up to. I want you to know... I won't let it go to waste. ... c'mere, pal."

Frisk smiles as they open their arms wide for a hug. "I just want you to know that I'm sorry. Chara...They are-" They wince and spasm in pain. "Strong, thirsty. Don't worry Sans, I'll love you always. Like family. And Chara will never change that."

"I know kid and that's why I'm sorry to," Sans says as a single tear flows out from the magical eye in his left socket. The guilt is destroying him, but it has to be done. Chara has to die and Frisk will only prevent him from achieving the justice all their victims deserved.

Frisk frowns. "Wait, what do you mean? Sans, what are you-" They scream as they find themselves falling down onto a bed of bones. With a sickening sound they land, dozens of miniature bones piercing their body. Frisk raise their hand weakly as the gory mess of themselves spreads between the bones. "Sans... I-I trus-" The hand falls limp. The soul cracks and shatters, the remains fading away.

The energy from the reload doesn't make the skeleton feel any less guilty. He knows he just killed his best friend in a act of traitorous betrayal. Not the emotionless murderer, but the real Frisk, the one he remembered. Who am I? He questions, looking down in despair. It felt horrible to kill the human that way. Just wrong. He killed them in an act of mercy. No different than how they killed his brother, Mettaton or Muffet. What have I done?

The human again traverses the hall, now stomping their way over without fluid grace. The human flickers to Chara and doesn't change back. What little of Frisk was left is now gone, having lost all faith and hope when he killed them. The knife is held in white knuckled hands, the human gripping it with a passion for his demise.

"Using my own methods against me are we now?" They say in a young, cold voice filled with insanity. "Have you really degraded so much as to use such tactics against me?" They laugh. Sans doesn't respond.

"Tell you what Sans, do you want to have a good time? Because if your getting a little tired I'll happily put you to sleep." They smile and lock their lips, twirling the knife between the pointer fingers. "You look like you could use a nap."

Sans pretends to think hard as he rubs his chin. "Let me think here a bit," he says. "Ummmm, no." He blinks and grins wider. "How about you get dunked on. That would be good time, wouldn't it?" He weakly laughs, nervous sweat running down his brow.

Chara gives a simple head shake, a madness beyond recognition in their eyes. "I'm going to kill you Sans. I can't die and you can't dodge forever. Your bound to make a fatal mistake."

A chilling laugh exits Chara's mouth. "I'll reset everything and kill everyone you love repeatedly in front of you. I'll pick apart your bones piece by piece, absorb you point by point." They point the knife at Sans blue eye. "I'll cut out your eye and keep it as a trophy for my own satisfaction." They twitch and jitter. "I'm going to make yo =)" Speech over they release a dark aura outlined in deep crimson around them. They move smooth fluid grace, a deadly intent flickering in their eyes, like a starving animal stalking its prey. Their heart flickers out in front of them, black with a crimson outline as the battle begins.

Sans stares dumbfounded at the human, overwhelmed by their sheer determination. Oh no, thinks Sans he begins to worry for the first time since this began. What have I done? How are they able to summon their true form? Did I really supply them with so much anger? Add the fact I just killed what little good remained inside of them, they are unbelievably powerful. On the plus side it meant this was the last battle. This must be what's left of their determination. If he killed them inside their true form, they will use up every ounce. They would be dead, permanently. But that would require killing Chara, something he doesn't think he is capable of.

It is time for the real fight to begin. Sans shrugs. "Let's just get this over with."
