The Crossover

1- Anti-void

Frisk's POV

MTT's restaurant. The place where I am now, standing infront of it. I'm about to go inside when I remember the dinner with Sans. I look at my left side and see him waiting there. Like I did in the last timeline, I go to him and accept his offer. We walk to an alley of the restaurant and teleport inside. I close my eyes to get ready for the impact. When I feel that we're inside the restaurant, I open my eyes and see nothing but white. I look at my side and see sans confused like me.

" Where are we and why are we here?" I ask.

"i dunno kid. maybe in an anti-void?" he answers unsure.

I sigh and think for a way to get out of here. Ah, why don't we teleport again?

"Hey sans, why don't you use your teleportation? You have magic."

"i already tried doing that but nothing happened."

'Oh' is the only word that came out of my mouth. If magic doesn't work here, then I'll do it my way.

"Hello?" I call, but nobody replied.

"what are you doing?" Sans questions.

"Is anyone there?" I call again, ignoring sans. There's still no reply.

"Hello~, is anyone the--" "you know, calling for help isn't going to work." Sans interrupts.

"But we need to get out of here. We can't just give up."

"i know kid, i also want to get out of here but it's so obvious that we're the only ones here and no one will hear us."

Well he has a point. I guess it's just us here. I stay silent for a while and think. 'No! You have to stay determined. Just walk around and eventually, you'll find an exit somewhere.'

Without any permission, I start walking. Sans though seems to be addled of my sudden action. He asks me where I will go. I didn't answer, instead I continue walking. When he understand what I'm doing, he also starts to walk and follow me.

*----------------------------*

I've been searching for minutes now, but there's still no exit to be found. 'Come on there's gotta be here somewhere.' I think to myself. Sans had been telling me to slow down a bit because of his 'laziness', but I just got faster every time he told me so. That's why he's quiet while walking.

Eventually I get tired, and decide to rest for a while. While resting, I see a portal coming out of nowhere, not so far from here. 2 humans came out of it . A boy and a girl. The girl has a long, blonde hair with red-horned headband on it and she's wearing a blue green sleeveless dress. She's holding a wand. The boy on the other hand is a brunette. He's wearing a red hoodie and a pair of jeans. And he's holding a pair of scissors.

Hmm, I wonder who they are .

Star's POV

"Rainbow Blast!"

Yes! 8 downs! I look at my surroundings and see that only few monsters are left. Marco's doing his job, the karate thingy when fighting. He had beaten 6 monsters already and I can see in his eyes that he's half tired but still determined to fight them. While he's fighting, an approaching beast is on its way to attack him. He doesn't see the beast though, so I come to his place and cast a spell. It seems that he's surprised because he slightly jump out of my sudden presence.

Once we took down all the monsters and made them retreat, we continue on our dimension hopping. We went to Amethyst Arcade, Pixtopia, Quest Buy and many more. We are now inside of Sandwich Dimension, searching for the monster who chased us last time and I want to get the other half of the sandwich for Marco. We've been searching for hours, no not hours, minutes, and there's still no sign of the large monster here. Taking a walk maybe? Eh, I dunno.

"Star we should go back now, it's getting late on earth, probably." Marco says.

" But you need to try out the sandwich. It's so good! even if the one I ate was all slammed." I encourage, saying the last part softly.

"Yeah sorry 'bout that. But you know that my parents get worried when we come home late, right?"

" Okay. But can we visit another dimension?"

"Star, we need to go--"

" Please?" I plead doing my puppy eyes.

"Alright alright, but this will be the last one, okay?"

"Okay!"

Marco readies the scissors and cut through the air. As he do so, a different portal come out. It is glitchy and its colors are white and black.

"Uhm Star, I don't think this is the right portal. I haven't encountered this one before. I'll just try another one." Marco says in a worried tone, already cutting into the air.

" No! we should try this one out. There might be new things in there that we don't know. We can also visit this dimension while we're dimension hopping. Beside you like learning new things right?" I say yanking his arm.

"Well fine. Nothing's bad in trying right? But if my parents get cranky, you know whose to blame,okay?" He gives up.

"OK!" I say diligently.

I enter the portal first and Marco behind me. Once already inside, I see nothing but white and the portal abaft us automatically closed. I panicked at first, Marco though, didn't even react. It seems that he had already experienced this kind of situation or is he just acting?

I look around to see my surroundings. My eyes caught a glimpse of two figures on the... INVISIBLE GROUND?! This dimension is so weird. Everything is white. LITERAL WHITE! I regret going in here.

"Now what? We're stuck in this dimension because of you." Marco blames.

"Hey don't blame me. We can use the scissors to go back" I request.

"I tried using them but it won't budge" Marco replies.

"But they're just working a while ago."

"I know. I don't know what happened to them."

"Oh, okay."

We stay silent for a while. And eventually, Marco speaks.

"What are we going to do now?"

Oh right, that one. I saw two figures sitting on the ground when we entered here. Why don't we approach them. It looks like they're alone before we entered here. I'm about to open my mouth until the two figures, whom I assume sitting on the 'ground' a while ago, approach us.
