Sans' eyes widened in shock, as he cannot believe what he is seeing in front of him. Why is there another him, but different? But...for some reason...this Sans reminds him so much of Chara, due to the black tar running down his eyes, like he is crying, the same thing that Chara had, as well as the knife that is in his hand. But the smile on this Sans' face...it reminded him so much of his own...when he faces off against the human to kill them.

"Sans...he looks like you!"

Rouge spoke out, as she was not expecting for this to happen. Sans spoke out.

"I can see that, Rouge. But...how is this possible?"

Sans spoke out, as the Sans-lookalike than gods in front of Sans and held his knife to his neck. But he does not love, and just stares at Sans.

As both of the Sans looked at each other, another voice, a female, spoke out.

"So...it seems that we are not the only ones here..."

The female voice sounded kind, yet...at the same time...it sounded very weak, vulnerable, as some footsteps got closer and closer to the 2 Sanses that are duking it out right now. Both Sanses and Rouge turned to see where the voice had come from. They wish they didn't have to...because the person that spoke out...let's say she isn't looking good.

Some of the right side of head, namely, the eyes and half of the lower part of her face, are stitched up with what seems to be rotten skin, and her left eye, which is the only one intact, is yellow and has some orange around the yellow, with he eye color being the only thing that's normal about her. Even Rouge feels like she is going to barf, sooner or later. But she holds herself strong, and spoke out.

"Who are you?"

Sans turned away, as he looked immensely revolted by the appearance of this Hedgehog Mobian right there. The person in front of them simply spoke out

"I am know as...Rosy. But you can call me...Amy Rose."

Rouge blinked at that.

"Amy?"

Rouge spoke out, surprised what she said. The original Sans and Rouge looked at each other, before Rouge took a picture, and showed it to Rosy. And Rosy was not surprised at what she is seeing. But the Black Teared Sans...he is actually surprised at what he is seeing. The face of the mobian in the picture...she has Amy's face. Except that the quill style and the clothing is much different than the Amy that he has been with.

"How is it that there is a different you?"

The black-teared Sans spoke out, as Amy spoke back.

"Sark...he told me about this. Different dimensions. Different versions of ourselves."

The normal Sans spoke out.

"Why is it that I'm not surprised? Having alternate timelines had been a pain, and this is one of such pains."

Rouge than looks at the others, before speaking out.

"Well...now that the reason is cleared up...how about we find a way to differentiate which Sans that we are talking about."

Both Sans blinked, as they looked at each other. And the instant they did, some tension and anger began to spark between the both of them at mere sight of each other, due to how one of the Sanses tried to kill the other.

Sans and Sans looked a bit ticked at each other, although Dust is more on the uncomfortable side, as the black-liquid Sans than spoke out.

"How about I rename you Dust, because of what is on your clothing."

Sans looks down, and the dust on his clothing...well...considering monsters turn to dust when they die...

"Fine. And you'll be named Killer. Got it?"

Killer Sans shrugged, as he spoke out.

"Ehhh...fits me."

Sans was suprised that he agreed to that, but he shook his head, as he spoke out to everyone.

"so...what do we do? share our stories of what had been going on from where we came from?"

Later...

"i just had to ask, huh?"

Dust spoke out, as they are now surrounding a campfire that Rouge was able to make, and with Sans using his flames to ignite the fire to make everyone warm. Everyone began to exchange few stories with one another, as Dust and Rouge spoke out their stories, and then...they decide to hear about Amy's and Killer's.

When involving Amy, she had been a servant to Sark when he killed her, but because she was not boomlet compared to the others, she had been abused badly. It even got to the point where Sark's version of Cream tried to dispose of her, only for Killer to come into play and save her.

Speaking of Killer, Dust finds out that...he and Killer are not this different. They slaughtered their own kind for the save if gaining more LV. The difference is that...Dust had been forced to do this, as he felt like he has no choice, and had to kill them in order to stop the human, so he can become more determined than the human that had caused them this suffering that Dust was forced to endure. Whereas Killer killed the monsters form his version of Mobius, because he had been manipulated by the human to do so, and because of this, he gained a split personality disorder...one of his original self...and the other...which is of his current, murderous self.

However...since Amy saw the original side of Sans, that being his normal heroic self, it reminded her of Sonic so much, that she decided to go with him, and acted as his moral compass. Because of this, the original part of Sans would at times resurface whenever Amy is around him, but as of now...Killer is still here. But Amy doesn't seem to mind, as she touches Killer's hand and tightened her grip. Killer Sans doesn't care, and simply just tighten it, even if it is slightly. Looks like this Amy has a crush on Killer Sans, and Killer seems to reciprocate the less feelings back. Though Dust is a bit unsure if he is genuine, or simply just does not care of what Amy is doing to his body, in order to keep up his friendly appearance.

"So...you've been going to the outside world...in order to find the survivor Mobians that...haven't been demonized yet?"

Amy spoke out to Sans, as Sans nodded.

"Yep. And I had a run in with your counterpart, who was demonized along with Sally. They tried to take Cream to Exetior. I was able to save her, but by that time...she had became nothing more than a broke shell of her former self, and I had to be the one that pieces her back together, so that she can be her usual self again. But other than that-ghhh..."

Sans held his head, as he feels a traumatic memory beginning to erupt from his mind. The event of the time...when he has to force himself to commit genocide. He remembered all the monsters he had killed, all the monsters he had slaughter...but more importantly of all...he remembered the time when he had to force himself to kill Papyrus, which drove him to the brink of insanity. Sans immediately snapped out of it, and Amy spoke out.

"I'm...sorry. This was a part of my power."

Amy spoke out, as she continued.

"I...can bring out traumatic events in people's lives...but I have no control over what I have. I am so sorry...that you had to remember that."

Amy's power had randomly targeted Sans' mind to make him remember the genocide? Well...that had somehow changed everything about him now. But...Sans sighed, as he spoke out.

"it's okay...and...killer...i want to talk to you in private. just the both of us. okay?"

Killer looks a little bit interested at what Dust wants him for in a private talk, but he stood up, and he walks alongside with Dust, into the deeper part of the woods. They walked and walked, until they are in a private spot that they can talk about what Dust wants to conversate to Killer about.

Dust than looks at Killer did a bit, as he chooses his words carefully, before he finally came up with a question that he wanted to ask him. He than turns around to look at Killer, and spoke out.

"there is a question that I want to ask you, killer. do you feel any remorse for-"

But Killer interrupted him.

"for all the people that I have killed, no. i don't feel any remorse for it."

Dust than spoke out.

"That's not what I meant. I mean...did you feel any remorse, of killing your papyrus?"

This made Killer freeze in his tracks, as this was not a question that he was not expecting.

"Why do you say that?"

Killer spoke out to Dust, as Dust spoke to him with a very sad expression now present on his face.

"Because I killed my Papyrus before I reset the timeline, and even though he is back...I still regret what I have done to him. I even have nightmare about killing him, and a hallucination of him that I can converse with from time to time, and he is much more crueler and ruthless than papyrus. So tell me, do you regret it? killing your papyrus, i mean?"

The moment that he said that, Killer immediately froze in his tracks, and his right eye began to turn white, as the original Sans retakes control of the body that he had, and the split personality of Killer was thrown back into the darkness of his mind.

Sans looks down with a unhappy expression on his face, as well as a look of regret present. He almost looks like that he wants to genuinely cry, but the only thing that he can cry is the strange black liquid that he has. Clearly...he does not want to talk about it...but seeing the scarf around Dust, and the fact that this scarf belongs to his younger brother, Papyrus, who he loves, silently nods at Dust, before Sans than spoke out to him.

"Yeah...I sure do, Dust. And everyday...I just wish I could take it back. Thinking about my bro...it always gives me immense pain. Because he is the reason that I still live as myself...and I had been taking care of him since he was just a baby."

Dust looks away for a bit, before speaking out to Sans.

"y'know...if you want, i can bring you to my world to see the papyrus of the underground that I live in. would that make you feel better, Sans?"

Sans was caught by surprise at what Dust just said.

"really? you'd allow me to bring me to your papyrus...after what i had done to my papyrus?"

Dust nodded, as he spoke out.

"Of course...besides...the expression on your face tells me that you regret it. so...i figure that being with my papyrus will make you better. and...one more thing, sans..."

Dust extended his hand and reach Sans' hood, before putting for over his head, as Dust spoke out.

"this looks way more better on ya."

Sans smiled, as he wears his hood like Dust. And Dust simply smiled, as Sans spoke out.

"Thanks, pal. It really means a lot."

Dust smiled, as he spoke out.

"Well...I guess you can say that I threw your sadness...down to the 'bone.'

Sans began to laugh, and spoke out.

"Hehehe...you're the same 'lazybones' just like me, aren't ya?"

Dust spoke back.

"Well...not really. I do still get bone-tired, though."

Sans and Dust continue to make puns left and right, as Rouge and Amy looked at the scene before them. And needless to say, it brought warmth inside of Amy's heart to see that the original Sans is now back from being trapped inside of the mind. So to see him smile the way he is is just a very heartwarming sight. Both Rouge and Amy smiled at seeing both Versions of Sans having some fun, even at a time like this. But as they looked...suddenly, a large red lighting strike appeared out of nowhere and tried to attack both Sanses.

"What was that?!"

Rouge spoke out, so she tan to check on Dust and Amy runs a bit to check on Killer. And as they checked on Dust and Killer...

"Hehehehehehehehehehehehehehehehehehehehehehehehehe..."

A demonic laugher was heard out of nowhere, and all 4 of them saw someone that looks like Exetior, but has a slightly lighter color blue.

"Sark..."

Sans spoke out, as he than stepped forward to see him. Killer retakes the body, as he looks up at the powerful demon that is floating above him. Sark smiled cruelty at Killer, who returns a similar smile, except it's a little more crazed than it is cruel.

"I found you, Killer!"

Sark spoke out in a loud tone. His tone is different from Sark's. It is cruel and demented at heart, and Killer spoke out in a crazed and demented tone himself.

"I know you did. But you are forgetting just how strong I am, remember?"

Sark didn't lose his smile, as he spoke out.

"Oh I know that...and I see you have made some allies for yourself to have! But that will not matter, because I am going to bring back what you had stolen from me!!"

He spoke out, regarding Dust and Rouge, and he regards Amy as his servant. Amy seemed to be frightened, as she steps back, but then...she felt a hand touch her shoulder in a comforting tone. She turns around to see that Dust is the one that has his hand on her. Dust than goes forward, before he pushes Amy Rose back a bit, so that she is behind Rouge, who goes in front of Amy in order to protect her from Sark, who has arrived. Dust continents stepping forward, before he finally stopped next to Killer, and he spoke out.

"so, you must be the so-called sark, that exetior's minions mentioned. heh. you don't look nor feel that impressive to me."

Sark simply looked a bit insulted, as he spoke back.

"And what do you mean by that?!"

Dust simply spoke out.

"i have felt exetior's power, and he felt way more stronger than you are. But even i admit that you are stronger than me. it won't change the fact that i'll be coming up to make sure that you get dunk on, Sark."

Sark smiled, as he than spoke out.

"Than I guess I'll have to make sure that your mind can for. And than you'll see why I am not someone you should look down upon, and someone you should fear!!"

He snapped his fingers, and Sark's version of Cream and Sally appeared.

Needless to say, Dust is a little grossed out by the appearance of Sark's version of Sally, her eyes removed and blood coming out of it. How she even knows what she is doing or where she is going to, Dust will never really know. But seeing Cream...like this...it made a twinge of anger become present in his eyes, as he bubbled with anger. But the fact that Cream is now with Sark, and is eternally loyal to him...well...Sans now has a reason to dunk Sark more than ever. Dust looks up and spoke out.

"that's it? you're just gonna send your minions to fight the both of us instead of you fighting us both yourself? Wow, I new you weren't as strong as exetior, but I never thought that you would be so cowardly, sark."

Exetior simply smiled, as he spoke out.

"Let's see how much you can smile once you become Cream's boy toy."

[There should be a GIF or video here. Update the app now to see it.]

This made Dust a bit ticked off, as he looks at Sark's version of Cream, who smiled cruelly at Sans, before speaking out.

"Come on, old man, are you to fucking scared to fight against me?!"

Okay, that makes it double to dunk Cream.

"Okay...you want to have a mad time, huh? Well..."

He than snapped open his eyes, as he smiled a bit more wider than ever before.

"allow me to give it to you, cream. let me show you what happens, when I go all out on little kids like you. And little kids like you...should be burning in hell."

He than raised Cream into the air, before sending her flying into a bunch of bones, before using the Gaster Blasters to attack Sark's version of Cream, causing her immense pain. But Cream was not down. In fact, she is now even more ticked off than ever before, as she charges at Sans, and used her ears for flight, just like the Cream of Sans' world can do, but much faster. She than launched spikes at him, as Sans launched Spears, in order to intercept the Spikes.

"y'know...it's a big shame that vanilla is unable to see you like this. she'd be so proud of what you had become, cream."

Dust spoke out with a sarcastic tone towards Sark's version of Cream, who got incredibly enraged and screamed out.

"Do not talk about my mother, you bastard!! You are already pissing me off!!"

It worked, and Cream is now charging on blindly in order to try and kill Sans for that insult, and Dust immediately charges at Cream, as she continues her fight against Dust. But Dust grabs Cream by the ears, and began to grind her against the ground, until Dust moved out of the way after she tries to summon a spike that would have killed him. Thankfully, Sans is still alive, and he fired a Fireball at Cream. She dodged it, but than, she was pierced by 4 of Undyne Spears, as she is sent flying back. She is than pinned by Asgore's trident, as Sans walked up to her, and began to beat her down. But Cream than broke out of the Trident, and went back on the offensive once more. Cream looks up at Sans, who is smiling down at her, psychotically, before she resumes battle against him once again.

With Killer, he is fighting against Sally. And despite having now eyes, she can still feel where Killer is at, and does all that she can to avoid the knife. Even she knows that, once you get hit by the knife, you are already done for. So Sally is trying all that she can in order to avoid getting hit by the knife. She than felt an opening, and tries to kick Killer in the leg. But Killer immediately jumps back, and defends against the strike that was supposed to hurt him. Than, Killer decides to use his magic and try to see if Sally can dodge these.

Killer summons more Red Knives, as he than fired them at the Sally to see how many she can dodge. She dodged many of them. She than got close enough to Killer, and was able to land some successful strikes on Killer. Unfortunately though, Killer is now immensely enraged, as he than decides to do as much damage as possible to Sally.

Killer than tried to attack Sally with far more aggression, in an effort to bring her down to the ground. Sally gets out of the way, but Killer teleports behind Sally, and slashes at her back, causing her pain. She than got stabbed by a few bones from behind, and Sasn than began to cause as much a damage to Sally as he possibly can. But Sally simply broke out of the bones, and attacked Killer by punching him away, as her wounds heal. Sally than looks at Killed, and spoke out to him.

"Sark's will shall be done, Sans. And you will not get in the way of what will be returned to him."

Sally than jumps towards Killer, and pummels him as much as she can, while Killer is doing al that he can to try and avoid Sally, before he than fired a Gaster Blaster at Sally, knocking her off of her feet, and sending her flying back. Killer smiled, as he used his red energy slash, in order to give off even more pain than before. Killer can't kill Sally, due to her being immortal. But Killer doesn't have to kill Sally. He just needs to cause her enough pain to knock her out cold.

Needles to say, Sark is not too happy about this, as he than decides to take the initiative to destroy both the skeletons, in order to finally kill them and get to Amy, but not before he decides to demonized Rouge.

"Tch! This is getting way to long to defeat those pathetic monsters!!"

He extended his hand at both Dust and Killer, as he began to fire a blast of energy.

"I'm end this, here and now!! The sooner these fuckers are dead, and the sooner Rouge can become my servant, the sooner that I'll get to have Amy back!!"

He than prepares his attac, when suddenly...

"AAAAAGHHHHH!!!!"

Sark roared out in agony, as everyone looked to see what is up...only to see that Sark's head has been hit with an axe. Sark rips the axe off of his head, which than began to heal the damage that he had taken. He than looks at the direction of where it came from, and shouted out to the one that did that.

"And who are you supposed to be, you fucker?!"

Dust and Killer looked behind them...only for their faces to drop at the sight that they hoped to never see.

"you have got to me be kidding me. another one?"

The Sans with the axe smiled...as he spoke out.

"one head dog comin' up."
