Sans looks, as he sees that a person is coming to see him. And needless to say, Sans is unsure who it is that is approaching him, as the light of the Blue Fire blocked most of his body, and he can only see the black coat.

"Is he a friend of yours?"

Sans spoke to Vali Lucifer, the White Dragon Emperor, who than shook his head, as he spoke out.

"No, I don't have a friend like that. This is different."

But when the person got closer...Sans feels like he is about to heave at the sight of the person that is now approaching him from the darkness.

The sight that he is seeing is immensely disgusting. It is a tall man, but he has patches of skin stitched all over his body, almost resembling the Frankenstein monster. The skin itself also looks burnt and scarred, and needless to say, Sans is very disgusted, as he can even smell burnt meat from them. And...Sans does not know why...but there is something awfully familiar about this person that he has no idea about. But he shakes off that strange feeling, as he than spoke out to the burnt man that is before him.

"Who are you?"

The man stopped, as his flames than extinguished, before he spoke out.

"You can call me Dabi."

Vali than looks at Dabi, and shouted out.

"Dabi...why did you interrupt our fight? This is between me and Sans!"

But Dabi simply laughed, as he than spoke out to the Dragon Emperor. Amusement present in his voice.

"Ohhh...than I will have to guess..."

His hand than ignited, as he than spoke out his last words.

"It is a fight between the both of you and me!!!"

Dabi than used his quirk, Cremation, on both Vali and Sans, as Sans made a Crystal wall in order to defend against the blue flames. The Blue Flames hit the Crystal, but it did not melt. It did however, glow blue, as the Abyss Crystal is now much more heated up than before. It is similar to metal, conducting heat.

He looks at Dabi, and he than spoke out.

"Too bad we won't be as easy as you think, pal!!"

But Dabi laughed as he spoke out.

"You had become exhausted from when you and Vali fought against each other. So you won't be able to beat me as easily as you had done before when against me."

Sans snarled, as Vali simply scoffed.

"Is that supposed to scare us, Dabi? I'm not afraid of you, and Sans is not. Besides...give me an amusing fight."

Dabi smiled, as he spoke out.

"As you wish."

He than launched a large fireball at them, and Sans and Vali moved out of the way, as the fireball hits the building, causing a massive explosion of blue flames. Sans looks and is shocked at what he is seeing, and realized just how dangerous Dabi is. But...the flames...he had seen them before...and there is only person that he knows of that is capable of making these flames.

"No...it...it can't be."

Sans looks forward at Dabi, and spoke out.

"Can it?"

Sans than looks down, conflicted with his thoughts. But he really should have picked the better time to do it. Because as soon as he did, Dabi is already behind Sans, and is ready to attack him. He turns around, and realized what was about to happen to him.

Sans than took a blast to the face with the blue flames. But he quickly was able to curl up into a ball and prevented himself from getting burned by the blue flames that Dabi tried to ignite him with. He did get launched back, but that did very little to hurt him. He than stood up, before summoning and launching his Abyss Shards at Dabi. But Dabi simply jumped back away from the Abyss Shards, as they hit something else. He looks very sadistic, as he than spoke out, well, tired to, as Sans simply went in front of Dabi, and attempted to fire an Abyss Chain at Dabi, who than is forced to jump back. But this was a mistake, as Vali was in the air, waiting for him. He than launched White Blasts of energy at Dabi, which hits his back, and he falls down to the ground very, very quickly. He than stands up to see Vali charging at him, and with only a second to spare, Dabi moved out of the way with his fire quirk, as Vali failed to grab him from the legs. Dabi than looks at Vali, and he spoke out.

"Is that the best that you can do?"

Vali smiled, as he spoke out.

"No. This is."

"DIVIDE!!"

Albion spoke out, as Vali than began to drain Dabi of his strength. Dabi, realizing what is about to happen, immediately launches a blast of fire at Vali, who is forced to dodge out of the way to avoid getting hit. But than, another blast of fire attacks Vali, and this time, he got hit, as he is launched into a building. Vali than busts out of the building's wall, and he than sees that Dabi has now resumed his fight with Sans once again. But Sans is fighting a little furiously. He does not know why, but there is a form of anger in his body, and it seems to be directed to the person that is in front of him, this Dabi. He does not know why, but his powers seemed to be very familiar.

Sans than lifts Dabi up with his Gravity Manipulation, before he launches him into a building, hitting his back badly. He than falls down back to the ground, as they fight on top of a building. Sans than dropped down, and landed on the ground without injury, and Sans looks to see Dabi getting ready to use his fire again. Sans jumped out of the way of flames came out of his hands. They hit a wall of a building, but that is all he did, and didn't hit Sans. And Sans is not behind the building. No, he is not. He is behind Dabi, as he then and kicks Dabi from behind his head.

This made Dabi stop for a bit, as Sans than grabs Dabi by the collar, and swung him into a statue, which than shattered into over a dozen small bits. He than stands up, as Vali than charged at Dabi, and began to strike him may times in the torso. But Dabi than unleashes his Blue Flames at full blast, which than launched Vali right off of him. Dabi stood up, as he than brushed the filth off of him. He than launched it as Vali again, but than, Sans used his Gravity Manipulation to get Vali out of the way as fast as he could, as the flames past aimlessly and non-threateningly in the air. Sans looks at Dabi, before he takes the turn to fly at him. He crouched from, his wings began to spread, before he than narrows his eye, and he takes flight towards Dabi, using it at full speed.

Dabi, however, was not afraid, as he than charged up and fired his attack at maximum heat, at over 2000 degrees Celsius. But Sans, though his speed, became fast enough to make the wind as his shield, and he was able to pass through the flames as if it is made up of nothing but the wind that flows free in the air itself. He than got closed to Dabi, and kicks him with some much force that it sends him flying back.

Sans smiled, as he spoke out to the unknown opponent that he is fighting against.

"Heh, you've given up yet pal? You should, because if I were you...I'd be freezing in hell itself."

Sans looks at Dabi, who begins to stand back up from the ground. He than looks at Sans with immense rage present in his eyes, but he stills keeps his calm, as he than spoke out to him.

"Feeezing in hell, Sans? No, I will be burning in hell? And you are going with me, so we can preform the dance of pain and torment."

Sans simply shrugged with his eyes closed, as he than spoke out.

"Sorry to break it to ya, pal, but..."

He than raised his left hand, and his left eye flower, as he spoke out to Dabi.

"Freezing is far more powerful than the fires that burn in Hell, and not even your flames can match the ice."

Dabi snarled, as he spoke out.

"I will send you there, one way or another."

He than began to ignite flames on his hands, as Sans looks at what it is that Dabi's doing.

"I am going to make sure that you regret ever fighting me in the first place."

Sans, however, does not seem to be afraid, as he simply summons his Gaster Abyss Blasters, and gets ready to fire them at Dabi, who is getting ready to use his power against Sans's attack. But as Sans gets ready...

"Mind if I lend you a hand?"

A voice spoke out, and Sans turns to see Vali landing down next to Sans with an eager look on his face.

"After all, I will make sure he pays for interrupting the battle he had between us."

Sans nodded, as he spoke out.

"Well, you're in, pal."

Vali than extended his hand, and white energy began to generate in his hands, as both Sans and Vali get ready to fight off against Dabi, who himself is getting ready to fight against them both. After a minute, Dabi, Sans, and Vali than fired their attacks at each other, and the battle of 2 against one commences. They both fought against each other, with one of them trying to overpower the other. Dabi and Sans do not take a step back, so that they do not accidentally get thrown by the sheer power of each other's attacks, by making a very bad stance. Vali, on the other, kept his stance, and than, began to use Divine Dividing power.

"DIVIDE!!!!"

The power of Cremation began to decrease immensely, and than, Sans and Vali's attacks overpowered Dabi's, who than moved out of the way, just before the combined attack hits him. The attack hits a fire hydrant, causing water to start leaking out and shooting up like geyser. Sans looks to see Dabi, and smiled, as he than spoke out.

"Yo, Dabi, so do you plan on giving up now, or do you still plan on-"

Than Dabi stood up and turned to Sans...as he than sees half of his hair is white, with black paint dripping off of his hair.

"...on...on...no. No!! It...it can't be!!!"

Sans shouted out, as he realized something. He than began to piece together why it is that this Dabi guy is so familiar to Sans in the first place, why the flames are so familiar to him in the first place.

Sans looks in horror, as he finally realized who it is, the white hair, the blue flames, only one person that he knows of can have a power like this.

"...Toya..."

Sans spoke out, as he remembers Toya, back in his childhood, when he first met him.

Flashback...11 years in the past...

"P-Please...leave me alone..."

Sans spoke out, as he tries to crawl away from the kids that are trying to hurt him badly. A 6 year old sans was having some fun in the park that he is in, but the kids that are about a year or so older are now hurting Sans for no reason at all. One of the boys than spoke out to him, followed by his buddy beside him.

"No way, freak!! This is so much fun!!"

"Yeah!! Beating you down for sport is so much better than seeing you run around!!!"

"It'll be a satisfying thing for us!"

He than was grabbed by the collar, and he sees that one of them was about to electrocute him in the head. He turns away, afraid of what was about to happen next, when all of sudden...

VWOOOSH!!!!

Suddenly, the sound of flames cracklings and sparking began to be heard, and Sans was dropped down to the ground. Than, screaming was heard, and he sees that the people that was going to to hurt him was running away from blue flames. He looked confused, and than, a voice spoke out.

"Hey, you okay?"

Sans looks and sees a 13 year old boy looking down at him and extended his hand. Sans doesn't know why, but for some reason...he feels safe to touch him.

Sans reached out to grab his hand, and he pulls him up.

"Th-Thank you."

Sans spoke out nervously, as the boy spoke out.

"Your welcome. Why didn't you fight back? You have powers, don't you? Why didn't you use them on those kids?"

Sans looks down, and he felt so ashamed, as he spoke out.

"My own power...it's bad. It scares me. I don't...I don't want people to know what it is. I'm a freak because of the power I have. I don't...I don't like to have this power. It feel so scared of myself

Sans spoke out, as tears went down his eyes, as he does not want to use his powers just to defend himself. He feels so terrified of who he is that he does not want anyone to know about it. Than...the boy says something.

"Don't be."

Sans looks at the boy with confusion in his eyes.

"Why should I not be afraid?"

Sans spoke out, as the boy than spoke out.

"Why? Because your power...it can be used to help people. It can be used to give people a reason to keep going, and prove that you are strong. Besides...who cares what people say about your powers? They do not have what you have. If you can just use it, it'll be fine. You don't need to embrace your power, just accept it. That is all you need to do. Nothing more. Don't pay attention to what other people think, because they are not you, and they do not know what it is like to be you."

Sans looks up and spoke out.

"R-really?"

The boy nodded.

"Really."

Sans smiled, and wipes the tears off of his eyes, as he spoke out.

"Thank you, and...by the way, I'm Sans. Can you please tell me your name?"

The boy smiled at Sans, and after a brief pause, finally spoke out his name to him.

"My name...it is Toya. Toya Torodoki."

End of Flashback...

Sans looks so...so horrified. The original 13 year old kid that he had once known, the person that had saved his life from the kids that had tried to severely hurt him...he had become this. Become a monster. No...not a monster. Something worse than a monster. Much, much worse than a monster. And there is only one word that he knows of that can fit that description.

"No...how...how could you...AFTER YOU HAD SAVED ME FROM THE KIDS!!!!"

Sans shouted out, as Toya looks amused, as he spoke out.

"That was who I was...as a pathetic little kid. As the son of the 2nd greatest hero, who wanted to make his daddy dearest proud."

Sans snarled...as he clenched his fist, and he than spoke out.

"I can't believe it...you were my hero...when you had saved my life from the kids that had tried to beat meh down mercilessly, bloodily. I looked up to you...and now, I am being replayed with this!!"

Sans snapped up, as he than decides to do one thing that he would do, when you betray him.

"You are cruel...you're right, that you are not the same as you once were. By betraying the ones that had looked up to you, by turning against them after how kind they were to you, you are not a villain, nor a monster...no, you are nothing more than..."

He than raised his right hand in the air, as he spoke out.

"...a megalomaniac."

He narrowed his eyes, which turned a black as the void, before he snapped it, and the entire area turned black. Vali and Dabi are with Sans, as Sans than spoke out.

"You're supposed to be the savior!! Not the betrayer!!"

He looks down at the ground, as he spoke out.

"And because of that..."

He than looks at Dabi, but in the way he sees it, Sans is larger, and gigantic, and this actually made Dabi shake in his shoes from the way he's seen by Sans, as he looks down at Dabi.

"YOU ARE GONNA HAVE A BAD TIME."

Sans later spoke out, in his rather creepy demonic tone, which only cells out just how enraged Sans is at being betrayed by the person that he had looked up to. Dabi than clenched his fist, as blue flames began to erupt from his fingertips. He looks at Sans, as he than spoke out.

"You think that you are going to kill me? This will only end in your death."

But Sand had a response of his own.

"The only ending that'll happen here..."

He than flies up into the air, as he extended his left hand at the side, as both of his eyes began to glow.

"...IS YOUR JUDGEMENT!!!"

He shouted out at the top of his lungs, as all 6 Gaster Abyss Blasters appeared behind him, and he looks at Dabi in a rage, before he fired them at Gabi. Toya immediately jumps back from the Gaster Abyss Blasters, but they have become powerful enough that they do not need to hit the target to cause damage. Even making an explosion is enough to injure Toya, which is what the Gaster Abyss Blasters had made when they exploded on the ground.

"Gahhhh!!!"

Dabi cried in pain, as he is launched back. Sans than raised Dabi up into the air, before slamming him into a building at the right, and he is forced to jump, in order to avoid getting pieces by the spikes. Than he is slammed down to the ground, and he jumps again, before Sans than launched him to the left, and here, he began to fly through the air, passing buildings, and he gets hit by a bunch of Crystal Bones, before being slammed into a building, and is forced to jump, before Sans than began to fire Gaster Abyss Blasters around him, and Dabi had to do all that he can to get out of the way. But he used his quirk so much that or began to blister and hurt his skin badly, and so when he stopped, he was in too much pain to keep going, and Sans, teleporting in front of him, than began to repeatedly slam Dabi around with his Gravity Manipulation, and hits him so badly to an inch of his life. But than, Sans got tired from slamming him around so much, and than...he was forced to put him down rather gently.

Sans could not believe that he had to fight off against the one that he had looked to, even though this person had saved his life. So what went wrong? Sans looks down and shakes his head, before he looks up and began to walk away. He than spreads his wings, and prepares to fly away, but than, he turns to see Dabi is gone, and Vali has now appeared.

"So...you took of Dabi, huh?"

Sans nodded.

"Yeah, but I didn't kill him. He's gone."

Vali nodded, before speaking out.

"Well...good luck, wherever you are going."

Sans nodded, before he than flies away, as he disappeared into the darkness, and opens a portal for him to go through, before he vanished from sight. The sun began to rise from the horizon, as the sunlight wakes everyone up from sleep.

Snowdin...

A blue portal opens up in Snowdin, and Sans than landed right onto the crunchy snow, as the snow he landed on scattered all over there whole place. He looks around and scrambled up, and looks around, before he sighs, and shakes his head. He...he just can't believe that the same kid that had saved his life, turned out to be a traitorous murderer who wanted to kill him for nothing. Why? Why does Toya want to kill the boy he's saved? He looks down with a very sad expression now on his face, and he clenched his fists, as he does not want to think about it right now. He than looks up, and decides to look around, and saw that no one is out just yet. He than decides to walk away, and go back to his home. He than stands up, and teleports back to his home, where Blake and Kuroka are still sleeping. He just hopes that he can feel better after he sleeps for a little bit. After all...rest can sometimes be Sans' escape from pain.
