You walked out of the restaurant and found yourself in MTT's Hotel, walking, you found a fountain with a Mettaton sculpture spitting water in the ground

Chara: Seems like it's working just like it should

Y/n: You can say that again

You see an elevator and some monsters in front of it

Chara: Isn't it supposed to go straight to Da... Asgore's Castle?

Y/n: I guess it is... But what's happening?

You go to the receptionist

Y/n: Uh. Hi, the elevator

Receptionist: Yes, we know. The elevator to the city is NOT working. Because of this incident, rooms are running at a special rate! 200G a room. Interested?

Chara: No fucking way!

Y/n: No, thanks...

Receptionist: Do let us know if you change your mind. Have a sparkular day!

You walk out and notice a big neon sign written "CORE"

Chara: Wonder where it leads to

Y/n: Let's find out

You both chuckle a bit and walk towards the door. You stepped in it and noticed that leading to the core, was a bridge. If you fall, you're dead

Chara: Why so many?

You noticed some guys staring at you and walking away. Then your phone starts to ring again and Chara jumps off of the bridge

Alphys: Huh? Who are they? N-nobody else is s-supposed to be here.

Y/n: Nice...

Alphys: Oh well! We can't worry about that now!

She hangs up and Chara just appears right in your side

Chara: It stinks down there

Y/n: Really?

Chara: Uhum

You both crossed the bridge and when you got to the other side your phone started to ring again

Chara: YOU'VE GOT TO BE KIDDING ME!

Alphys: Ready? This is it! Take the elevator to the top of the core

She hangs up and Chara checks the elevator

Chara: Dude, it's not working

You try to open it, but to no avail, so magically, your phone rings again.

Chara: Of course...

Alphys: What? The elevator should be working... Well then! Go to the right and keep heading up!

She hangs up again and you follow her lead only to find an empty room with fire on the pit... Surprisingly... Your phone rings...

Alphys: Alright, now just keep heading up!

Y/n: There's a pitch-black pit preventing me from doing it...

Alphys:...that pit... Isn't on my map... Forget it! Let's try the left side!

You hang up and walked out of the room, going to the left one. You entered it and... You guessed it, your phone started to ring

Chara: I DON'T LIKE HER!

Alphys: Okay, you should be able to make it through here...

A figure approach you and Alphys yells

Alphys: W-WATCH OUT!

Madjick pops out of its hat!

You stare into Madjick's orbs and they suddenly close before Madjick could attack you, so it walked away from you

Alphys: Th-that was close... Wh... Why are there so many monsters in here? I mean... It's no problem, r-r-right?

Y/n: We'll see...

Alphys: W-w-we've just got to keep heading forward!...

She hangs up and you kept walking forward

Chara: It stinks in here

Y/n: Yeah, hey, what's that?

You point towards a force field and your phone rings again, how exciting

Alphys: Looks like you can't proceed until you hit the switch. B-but, those lasers will activate when you do... Ummm... Looks like they'll come in this order: orange. orange. blue.

Y/n: Kay

Alphys: G-got it? Move until the third one!

She hangs up again and you hit the switch which makes the lasers come right at your face, at the opposite order that Alphys said, but you were fast enough to... Not move until the third one. You kept walking towards the exit of this room when...

Alphys: Oh my God, are you okay?

Y/n: Just fine

Alphys: I... I'm sorry, I gave you the wrong order...

Y/n: Are YOU okay?

Alphys: E-everything's fine, okay? Let's just keep heading to the right

She hangs up again and you sigh looking at Chara

Chara: We're almost there, c'mon

You both kept walking right until you both stumbled upon a crossroads. So...

Alphys: A crossroads... Uhh...

Chara: OH MY GOD. I WILL GO!

She says rushing right

Alphys: Uhhh... Try heading to the right!

Alphys hangs up and calls again

Alphys: W-wait! No, I think you should h-head up!

Chara comes back and Alphys hangs up

Chara: The right way is the right one

Y/n: What's in the up way then?

You both got up and found a monster almost sleeping

Chara and Y/n: Yeah, I should have imagined

You and Chara start singing a lullaby melody while trying to avoid its magic spells, you and Chara kept singing until the monster falls asleep and...

Alphys: Sorry, I... I... I thought that... Let's try the right path instead...

She hangs up sounding sad

Chara: Let's go, we're done here anyway

You both go right and find some lasers in a bridge

Y/n: I officially hate bridges...

You try to cross the bridge but...

Alphys: M... More lasers...

Chara: I officially hate her...

Y/n: Yeah, more lasers...

Alphys: Okay, I... I won't mess around this time. I'll just deactivate the lasers and let you through...

Y/n: What's the holdup?

Alphys: They're... They're not turning off...

Chara: Wow! What a hacker!

Alphys: I can't turn them off, I... I-i-it's okay! I have this under control! I'm going to turn off the p-power for that whole node. Then you can walk across

Y/n: Sound good to me

The power is turned off

Alphys: Okay, go!

You run across the bridge but you see the lights flickering, so you just stop and...

Alphys: W-WAIT! STOP!

Chara: Classic Alphys...

Alphys: Th-the power... It's turning itself back on. D-damn it... Th-this isn't supposed to... I... I'm gonna turn it off again

Y/n: Okay

Alphys: When it turns off, move a little, and then STOP!

Y/n: Okay

Alphys: Y-you won't get h-h-hurt.

The power is turned off and you run as fast as you can, when it starts to come back on, you launch yourself to the other side of the bridge

Chara: ARE YOU NUTS?

Alphys: S-see? I've got everything under control. Everything's under control!

She hangs up and Chara is almost killing you with her gaze

Chara: YOU ALMOST DIED YOU... IDIOT!

Y/n: Calm down, I'm okay, relax!

You get up and keep walking

Y/n: I'm not even hurt

Chara: Okay... Be careful...

You find another save point and...

Alphys: OK! Y-you should... You should...

Y/n: Where do I go?

Alphys: I don't know? This doesn't look like my map at all... I'm sorry... I... I...

Y/n: It's okay Alphys, just rest a little

Alphys: Okay... I have to go

She hangs up and Chara looks at you

Chara: So...?

Y/n: Guess she's MIA

Chara: Yeah!

You both start looking for an exit, but the only thing you were able to find, was monsters to fight, you had to fight and dodge at least 30 monsters in total, you walked left and right until...

Chara: I FOUND A PUZZLE!

Y/n: I found 100G in a trash can...

Chara: Who would throw 100G away?

Y/n: Don't know, but now it's mine, so... Puzzle?

Chara: Yeah, here, look

Y/n: Easy

You solve the puzzle and hear a faint "click"

Chara: Now we have to find the exit...

Y/n: I found a switch and pressed it, I don't think it will be that hard to find it

You both kept walking around this maze trying to find the exit and found a bridge with some monsters, so you hanged on the edge of the bridge and passed it without fighting any monster, finally being able to save again.

Chara: I think this is the elevator that wasn't working before...

Y/n: So the path is... This black as hell room

Chara: Smells like metal

Y/n: Yup!

You both entered the room, and in the middle of it, a microwave was resting... Oh, wait... It's Mettaton!

Mtt: OH YES. THERE YOU ARE, DARLING! IT'S TIME TO HAVE OUR LITTLE SHOWDOWN. IT'S TIME TO FINALLY STOP THE "MALFUNCTIONING" ROBOT.

Chara: I don't think you're Malfunctioning, just weird

Mtt:... NOT!!!

Y/n: Don't just scream... Please...

Mtt: MALFUNCTION? REPROGRAMMING? GET REAL. THIS WAS ALL JUST A BIG SHOW. AN ACT.

Y/n: Everything was recorded then? Geez...

Mtt: ALPHYS HAS BEEN PLAYING YOU FOR A FOOL THE WHOLE TIME.

Chara: She really wasn't...

Mtt: AS SHE WATCHED YOU ON THE SCREEN, SHE GREW ATTACHED TO YOUR ADVENTURE. SHE DESPERATELY WANTED TO BE A PART OF IT. SO SHE DECIDED TO INSERT HERSELF INTO YOUR STORY.

Y/n: Okay...

Mtt: SHE REACTIVATED PUZZLES. SHE DISABLED ELEVATORS. SHE ENLISTED ME TO TORMENT YOU. ALL SO SHE COULD SAVE YOU FROM DANGERS THAT DIDN'T EXIST. ALL SO YOU COULD THINK SHE'S THE GREAT PERSON THAT SHE'S NOT

Chara: NOW I feel a little bad about her. Just a little bit...

Mtt: AND NOW, IT'S TIME FOR HER FINEST HOUR.

Y/n: What?

Mtt: AT THIS VERY MOMENT, ALPHYS IS WAITING OUTSIDE THE ROOM. DURING OUR "BATTLE", SHE WILL INTERRUPT. SHE WILL PRETEND TO "DEACTIVATE" ME, "SAVING" YOU ONE FINAL TIME. FINALLY, SHE'LL BE THE HEROINE OF YOUR ADVENTURE. YOU'LL REGARD HER SO HIGHLY SHE'LL CONVINCE YOU NOT TO LEAVE... OR NOT.

Y/n: Twist?

Chara: Yup

Mtt: YOU SEE, I'VE HAD ENOUGH OF THIS PREDICTABLE CHARADE. I HAVE NO DESIRE TO HARM HUMANS.

Y/n: Really?

Mtt: FAR FROM IT, ACTUALLY. MY ONLY DESIRE IS TO ENTERTAIN. AFTER ALL, THE AUDIENCE DESERVES A GOOD SHOW, DON'T THEY?

Y/n: Yeah?

Mtt: AND WHAT'S A GOOD SHOW... WITHOUT A PLOT TWIST?

The door behind you closes and you can hear knocking

Alphys: H-hey!!! Wh-wh-what's going on!? Th-th-the door just locked itself!

Red spotlights illuminate the center of the room

Mtt: SORRY, FOLKS! THE OLD PROGRAM'S BEEN CANCELLED!!!

Chara: Here we go...

Mtt: BUT WE'VE GOT A FINALE THAT WILL DRIVE YOU WILD!!

The platform starts to rise up int the air

Mtt: REAL DRAMA!! REAL ACTION!! REAL BLOODSHED!!

Chara & Y/n: REAL WHAT?

Mtt: ON OUR NEW SHOW... "ATTACK OF THE KILLER ROBOT!"

Mettaton attacks!

================================

A/n: Sorry not sorry
