Y/N POV

It has been a month since Toriel found out about the dragons, and let's just say she was NOT happy about them, but after a misunderstanding with them and getting to understand the dragons, she warms up to them we also named the other two dragons, sans'es one was named specter, mine was named gasper, and papyrus wanted to rename his so he went with spectre, yeah three ghost names but it fits them at least due to there appearance, Alphys did her presentation quite well which wasn't surprising, and Undyne got a job as a cop... there were some doubts but after a week of her doing her job she caught 13 criminals in one week, yeah it isn't that surprising... I was right now in a Forrest sitting on a log thinking

Y/N: ' ' it has been seven or so months since the barrier was destroyed... Frisk, Chara, and Asriel went to school That toriel owns... Sans somehow owns and runs a convenience store with Papyrus being his only employee... Asgore works as a gardener, Undyne works as a cop, and Alphys still works as a scientist... And I am the only one that doesn't work...' *sigh**mutters* I don't know if I could get a job... I don't think anyone would accept me as an employee... Probably Sans would take me in... But... *sigh*

As I blinked I found myself in a white void, I was extremely confused on how I got here I then start to walk forward, as I walked I looked around at my surrounding's but after a few minutes I see a figure sitting, as I was about to speak the person spoke first

???: You're voice can't be heard in this place... But... Who are you...? Are you just a random monster living in the true pacifist timeline...? No... That can't be it, unless... Do you have a friend named sans?

I was a bit nervous to reply, and they notice this

???: Oh, don't worry. Your timeline won't change when you-... Well... Let's just say no one will notice anything different when you're gone... BECAUSE... I... AM... HIM...

I for some reason  start to charge up my atomic breath and they noticed this and took it as a bad sign, they then away there arms around in fear

???: Hey, wait! Calm down! I'm j-just joking with you! I just... I just want to be happy before I die... I only have one day to live... I don't have anyone else. Please... Let me spend time with my loved ones. Let me stay in your timeline in a while, I won't hurt anyone and-

I then stopped charging my atomic breath and made it dissapear, I then turn around and started to walk away, thinking that they were lying, they got angry at this

???: HEY! WHERE ARE YOU GOING? I HAVEN'T FINISHED YET!

As I was walking away I noticed that my soul turned blue, and I got pulled towards them and then...

HP [III       ] ???/????

I was on one knee feeling extreme fatigue on my body and half of my soul was in there hand, and they were shocked at the appearance of my soul they then shake there head and looked at me, and started to speak they had sans'es voice now

???: Never let your guard down. You should listen to undyne when she gives you advice, even though you don't know her... I had just wanted a few minutes, but now your selfishness has given me many, many, many years to live! And with this soul... I might have the power to finally beat... HIM... That was much easier than being nice to you, huh?

The white void turns into the Forrest that I was in

???:With this part of your soul, I can have a new, bright life in your universe.*looks at me* C'mon, bud. Don't look at me at me like that. I'm just giving you a looong break that will last... FOREVER... But I wonder... What would happen if I had YOUR entire soul... Let's find out shall we?

Before they could do something, a skeleton with a paintbrush paints rainbow on their face

Skeleton: You will never find happiness in someone else's timeline, C!

??? had a look of anger

???: YOU AGAIN!? GET LOST! Or I'm gonna destroy this timeline forever! No more of your pacifist crap!

Skeleton: Stop fooling around, C. Give him his soul back, and we can go home, ok?

??? then summons blade like spikes out of the ground

???: GET LOST NOW

Skeleton: Oh, are you serious?*closes eyes* welp, you asked for it. Y/N, stay behind me. I'll try to make this quick

??? then tries to attack the skeleton but he dodged and they got hit by the paint brush of the skeleton, smearing pink paint on them, they then attack the skeleton and he dodges, the skeleton then attacks ??? smearing more pink paint on them

???: STOP DOING THAT

Skeleton: Hehehehe, I warned ya! Besides, you gotta admit this is fun

His soul then turns purple and lifts him up in the air, I watch in slight worry on what would happen

???: I don't care if I kill you, ink... Not anymore... Did you really thing that your stupid paintbrush can stop me? HAHA! All of you are so WEAK!!

The now known skeleton, ink spoke up

Ink: If i were you, I wouldn't say that. There's something called "Creativity and Strategy"

He then snaps his fingers, making purple chains appear on them and it tightens

???: WHAT!? NOOO!!

Ink: Y/N! NOW!

I snapped out of my deep thought and made spikes around them, I then got up

Y/N: welp that just happened * back cracks* oof... I'll feel that one in the morning, but anyways... I dunno what's happening but it is obvious that you don't belong here. So please stop this. Now. And also please give me back my soul. I'm pretty sure that this other sans can help ya

Ink: C, I promise everything will be ok... Let's go home... We'll find a better way to-

???: I just don't want to die... I just... I need...

There voice suddenly changed to a familiar one

???: WE NEED OUR OWN UNIVERSE!

Y/N: Wha-

Ink: NO! WAIT!

They then disappear, meaning they could use "shortcuts" I then look at ink

Ink: this is bad...

Y/N:... So are you going to explain on what is happening, and how do you know my name? Because I am very confused...

Ink: *sweatdrops* figured...

Somewhere in a yellow dimension...

??? POV

I have made it to an unknown place...

???: WE DID IT! HAHAHA! This is half of that monsters soul! But I do wonder... How does that monster have a rainbow soul...? Eh, but now I have a better idea... Let's take that other monsters soul, and create our OWN UNIVERSE! And... Maybe defeat... HIM... And we don't need to live in a used, boring timeline... We can make this more interesting... But first, let's absorb this soul. Are you ready? Sans: ... Yeah... ???: ... What's the matter? Are you... Sans: I'm not sure about this, Chara... Ink was trying to help us... That monster refused to fight... Why do we have to do this? Chara: are you afraid that I'll break free?

This sans kept quiet, until Chara spoke

Chara: I made you a promise "sans". I promised to be your friend... Those dark days are over. You gave up a long time ago, but not me. I'll help you rebuild the world we lost...

HP [           ] 0/0

We deserve a new hope

Chara: it's what they would have wanted

Sans: ... Let's just do it.

              HP [IIIII     ]  0.5/0.5   

*You used Y/N's soul half.
*You recovered 0.5 HP!

It now pans to Sans freed from the chains

*A new SOUL lies within you.

Meanwhile with Ink and Y/N...

3rd POV

They were sitting on the grass, after ink explained what happened earlier Y/N was processing the new information

Y/N: So... Your name's Ink, huh?

Ink: ... Yup. Nice to meet ya

It was silent for a few moments, until ink broke the silence

Ink: I-Im so sorry, Y/N. I never thought this could happen...

Y/N: why are you apologizing? It's not that bad... Right? And atleast I'm not dead... At least not yet...? But that Sans  loves to cause some trouble I guess

Ink: Actually, this is the first time he's done some thing like this. He's scared since... Well... It's a long story...

Y/N then thinks If he should listen to this story, and he ends up the decision to listen to it

Y/N: Umm...  I can listen to it if you wa-

Ink then vomits a black substance and he turns to Y/N with stars in his eyes, and Y/N was a bit disturbed at the vomit that Ink did

Ink: YOU WANNA KNOW MORE ABOUT C!? GREAT!! Ehem! Sorry about that, heh... Alright... It all started with a simple drop in a far universe...

The scene then changes to Ink drawing inside his realm

Ink: Everything seemed to be normal. Your universe and the thousands of variations still continued on peacefully. Suddenly, I felt the appearance of a new universe. It had a very strong presense... Despite having the sound of dripping water.

Flashback Ink then throws away his pen and notebook, and uses an ink portal to go to the new universe

Ink: I couldn't contain my excitement, so I decided to go there. I was eager to meet this new world and it's inhabitants... But there was absolutely nothing except for one person... And actually... Those drips were his tears

We then see a crying hooded figure, and he turns around to see Ink, and Ink then sits Infront if them and he backs away from him slightly

Ink: he was scared. His mind was invaded by horror. He noticed there was someone else... Me

Flashback Ink then gets out his pen and notebook

Ink: however, we soon broke the ice, and he told me his name

The scene then shows Ink showing him his drawings, and the hooded skeleton wipes there tears a way

Ink: he called himself Cross, the only survivor of a Genocide Run with not RESET possibilities

Y/N: ...Genocide... Run? I don't get it... Why would he be in a Genocide? Also what's a RESET?

Ink: *sigh* there are three outcomes for every AU, one is true pacifist, which is the one your in right now, there's neutral where the human killed a few monsters in self defense... And then... there's genocide... Where the human did a mass genocide on the monsters... And RESET is where the human can restart the timeline at will

Y/N: oh... Ok then... Then where's the human or Frisk in that universe?

Ink: the human that did the mass genocide... His name is Chara... And he is sealed inside of Cross's body. How did it happen? He never told me...

Y/N: oh...

Ink: At first, they acted as two separated beings at first, they acted as two separated beings

The scene then shows Ink did a whoopee cushion on the hand trick on Cross, and he did not look happy

Ink: however, as I visited cross to keep him company, he won full control of the soul

the next scene then shows Ink in a cosplay which amazed Cross, and the next scene shows Ink holding his paintbrush and paints rainbow on Cross's head, the next scene then shows Cross chasing Ink, and the next scene shows Cross running away with Inks paintbrush with Ink close behind, the scene now shows Ink and Cross drawing and Cross suddenly stands up

Ink: One day, while we were drawing stuff, he stood up. He looked pretty down in the dumps. He told me that a strange child appeared in his world, and tried to convince him to go to a place with other survivors like him. He refused to go, because he was convinced that his world was still alive. Cross thought he could restore everything with my help. But when I told him that I can't resurrect the dead...

The scene shows cross with a devastated look, he also had red eyes

Ink: his face...

Ink now had a blank look on his face with no eyes

Y/N: resurrection, huh...

Ink: ... What were we talking about?

Y/N: we were talking about cross's story

Ink: oh, yeah right... Anyways... His last hopes and dreams came to an end... Because he met the end of his loneliness...

The scene then shows Cross getting up and a figure was seen in the distance, he then notices this figure

Cross: ... Ink? Is that you?

Blue strings came out of the mysterious figure hands, and it grabs Cross, the figure then reveals itself as a glitching skeletons with errors floating around himself

???: HUMM THIS PLACE IS PRETTY BIG FOR ONE PERSON THAT IS KINDA SELFISH Y'KNOW

The strings went to Cross's soul and his soul was shown to be and upside down with a white and red color

Ink: Their soul was extracted by Error... When I came back, it was too late...

The scene then shows Ink attacking Error, and he dodges Inks paintbrush, Error then summons red bones on the ground, while Ink uses one as a platform

Error: Ink, Ink... Why do you insist on protecting this anomaly? You know you can't help them anymore

Ink: I wanted to save Cross's soul, but I couldn't let his world be destroyed...

Error: Let me give him a happy ending this time.

Ink: NO! THAT'S NOT YOUR JOB!!

Error: welp.

He summons seven glitching blasters that are charging up

Error:  I TRIED TO BE FRIENDLY

After a few moments of silence, in a blink of an eye Ink manages to free Cross using his paintbrush and the blasters fire, the scene now changes to a glitching red and white soul

Ink: Error took Cross's soul away, but he couldn't take Chara's powerful and sadistic DETERMINATION. Due to that, they were both able to stay alive with a deadline. Fighting each other for the control of that corrupted body

Chara: I'm... FREE! Cross: NO!! STOP!

Ink then turns his head to the glitching Cross and Chara

Ink: C-Cross...? Are you alright?

Ink: When they saw me hurt, they ran away. I could never find them

The scene shows Chara smiling at Ink, and with a snap of there fingers they disappear, the scene now shows Chara and Y/N with Chara's back is facing Y/N

Ink: After that, Cross and Chara teleported to your timeline and somehow, intersected their world with yours to take classics place before dying... But... They ended up with you somehow... Spending their last few minutes in a world they once had. Now I realize this Chara got to convince Cross... Maybe he pretends to use half of that soul to keep themselves alive, but, he's scheming something else. Someone capable of manipulating a monsters body with that twisted mind... It could be really difficult trying to stop them. And this begs the question... How do you have a rainbow soul?

Y/N: dunno, when I fought Undyne and Mettaton... My soul was green and yellow, and I gained the abilities like a magic shield and a magic pistol, and when I tried to show my soul to Asriel but... I made a half monster soul on acc-

He was cut off when ink puked and turned to him with exclamation marks in his eyes

Ink: YOU CAN CREATE MONSTER SOULS?!!!

That itself caused Y/N to fall of the log that he was sitting on, and that made Ink worry, Y/N then gives a thumbs up in the air

Y/N: *dazed* I'm... Good...

He said with spirals in his eyes

Ink: oh, umm... Sorry...

Y/N: I'm good, I'm good...

Ink then gets up and turns to Y/N

Ink: I have to admit that I can't stop them by myself... I know this isn't right thing to do but... Y/N... I need your help to find Cross... Would you like to come with me?

Y/N then thinks for a bit, after a few moments of silence he speaks up

Y/N: alright then *gets up* so where are we going first?

Before Ink can reply he was sucked into a black portal, leaving a confused Y/N behind

Y/N: uhh... What just happened?
