-Timeskip (10 years)-

As years went by, you and the skelebros grew up as a happy family. You, Sans, and Papyrus were finally free. The three of you, had hand plates on your right hands, but the three of you kept it a secret from everybody. Papyrus placed gloves on his hands, Sans just keeps his right hand in his jacket's pocket, and you just wore black gloves, to avoid anyone from seeing the black lines on your hands, and the hand plate on your right hand.

Sans and Papyrus lived in Snowdin, and you live somewhere in Hotland, just near Alphys' lab, but your lab was bigger, and filled with more research. If you ever wondered, what happened to Dr. Gaster, he fell into the core, and never came back. Sans and Papyrus weren't afraid. You on the other hand, changed.

(I KNOW!!! I WAS TOO LAZY TO COLOR HER HAIR!!! THE BACKGROUND LOOKS DIRTY I KNOW!!! I didn't bother coloring her hair, since Reader-chan has different colored hair, plus I was too lazy to color her hair. Lazy me :3)

Your appearance changed, and so did your attitude. Your eyes stayed the same color as you were in the lab, 10 years ago. Your skin was as white as Sans' and Papyrus' bones, it's like you were a skeleton yourself. You began to have black lines on your hands, like the ones from Gaster.

You were as smart as Dr. Gaster, and decided not to continue his research, since he made you into his successor. If you did continue, you would have already killed Sans and Papyrus, you didn't want that. You gained magic, the same magic as Sans and Papyrus, only yours was stronger. You were no longer human, you were something more. More powerful. You had over 1000 HOPE, you were one of the strongest monsters, or human, or hybrid.

You tend to shut yourself from the outside world from time to time, just to focus on your work, but Alphys would always offer to help, along with visits from Sans and Papyrus.

You were in your lab, figuring out the formula for the 7 souls. It was a big responsibility, you being in charge of the formulas. You already had the fragment of 6 souls, but one was missing. Determination. You couldn't find the right formula, even if you had to mix fragments of the other six souls.

Then a knock came in your door. You sighed, and put down the vile. You walked up the stairs, but only to trip on one of the steps, and faceplant unto the floor. Embarrassing. Luckily no one saw that. You dusted your lab coat, and walked towards the door. "Who is it?" You look into the peep hole. It was Sans, Papyrus, and a small person you haven't met.

You opened the door, and only to be greeted by Papyrus hugging you. "HELLO, DEAR (Y/N)! HOW HAVE YOU BEEN?" Papyrus exclaimed, as you patted his back. "I'm doing more research than usual. Monsters are being impatient and all...." You said, as Papyrus put you down. Sans waved at you, having a blue blush on his face, you waved back, and smiled a little. Then there was this smaller person. A human.

"OH, THIS IS THE HUMAN I WAS TELLING YOU ABOUT! THEIR NAME IS, FRISK!" Papyrus exclaims, carrying the human. "Hello." Frisk greets, as I smile. "Hello, Frisk. I'm Dr. (Y/N)." You greeted, as Frisk smiles at you.

"So, is that all you guys came for? Because I'm a little busy..." You said, as you crossed your arms. "Well, we did plan on having a battle with you, because Frisk here wants to see how powerful you are. " Sans answered. You sighed, and rubbed your temples. "You both know that, I'm always busy, and yet you both come here, and tell me 'Can Frisk see my powers'? You're both so childish.... But...." You bent down to Frisk's level, and said, "I'll make an exception, for the human... But just this once...".

Frisk smiles, and Papyrus hugs you again. You smiled, as Papyrus puts you down. All of you head outside the lab, and Sans, Papyrus, and Frisk watched you do your magic. "Okay, but this is just once." You said, as you look at Sans. "Sans. You have been increasing your defense, and HOPE, am I right?" You ask him, as he shrugs, and shakes his head. You sigh, and curse under your breath. "You are good at dodging my attacks though, so it will be easier to show my magic, without hurting you. Be ready." You warned as your eyes started to glow.

"Heh. Don't worry, Babe. I've got this." Sans says, as you blush. You summoned your Gaster Blaster, and it shot out it's beams. Sans was able to dodge it, and you turned his soul into a different color. Half blue, and half orange. He floats on the same spot, chuckling. "Woah! That's so cool!" Frisk exclaims. "YEP! THAT'S OUR DR. (Y/N)! THE BEST GUARDIAN EVER!" Papyrus exclaims, as Frisk stares into the battle.

You put down Sans, and your Gaster Blaster vanishes. "More! I wanna see more!" Frisk exclaims. You shake your head, and you put down Sans. "Sorry, I gotta get back to work... You're welcome to stay, if you'd like. Just don't disturb me..." You say, as you headed back into your lab, along with Frisk. "SORRY, (Y/N)! I HAVE TRAINING WITH UNDYNE! I'LL PICK FRISK UP LATER! SEE YOU LATER!" Papyrus says, as he goes to Undyne's house.

"Welp. I'm going to Grillby's. See you later, kiddo. Take care of, Dr. (Y/N), for me will you? She's very special." Sans mumbles the last part. Frisk tilts their head, but then nods in agreement. Sans teleports away, leaving you with Frisk to babysit.

"So you're telling me, that Sans and Papyrus, just passed by to drop you off here?! Unbelievable." You rubbed your temples, as Frisk looks up at you, and smiles. "What is it, Frisk?" You ask, as you looked down at them. "Do you like Sans?" Frisk suddenly asks, as you flinch, and your face turns red. "W-Why would you s-say that?!" You asked, nervously. Frisk giggles, and looks at your red face. "Because the way that, Sans, looks at you. I think he likes you!" Frisk exclaims, as you blushed an even deeper red. You cleared your throat, "N-Nonsense! I know him! And he doesn't like me! and That is the truth!" You protested.

"Hey Dr. (Y/N), can I ask something again?" Frisk asks, with a look of curiosity on their face. "If it's about me and Sans could be a couple, then no." you said, in a stern tone. "Actually... I want to know, your connection with the Font brothers... is it okay to ask?" Frisk asks, as you stop at your tracks. "Well... I can't tell you... not right now... You can just ask the Font brothers later, when they pick you up, alright?" You tell Frisk, as they shake their head. "Another question, are you a human? or are you a hybrid...?" Frisk asks again. You face them, and bent down to their level. You patted their head, and let out a fake smile. "I used to a human, but something happened, and it isn't worth talking about. Don't push it." You said, as you stood up, and started to walk down the long hallway again.

You dusted your lab coat, and headed back to your lab. Before you could even open the door, Frisk tugs on your lab coat. "What is it, Frisk?" You asked, as you turned around to face them. "Where can I go in the house?" Frisk asks, as you raise an eyebrow. "Well.... You could stay here and watch some anime, that Alphys lend to me, or you could just take a nap on the couch, or you could read some of my books. Just don't enter the lab. I mean it." You said, as you head into your lab, leaving Frisk sitting on the couch, playing games on their phone.

You sighed, and continued your way back to your lab. Just as you closed the door, you heard a dark, and raspy, yet oddly familiar voice,

"Hello... Dr. (Y/N).... Or should I say....", you turned around to see him. "Subject 3...."

You gasped, and your eyes were widened. "G-Gaster...?! N-No... you... you were finally gone!" You whisper-yelled at Gaster. "Why... didn't you... continue... my research.... You... were... my successor...." Gaster whispers, and slowly approaches you. "If I did, I would have already killed Sans and Papyrus! My only family left! You Psycho!" You yelled, at Gaster. He frowns, but then he shows his creepy smile.

"If... you won't.... continue my research.... I will just make you...." Gaster's pinpricks glow, as your's glows as well. You prepared your magic, and fired your Gaster Blaster at him. It was direct hit, but as the beam faded, he wasn't even damaged. "W-What?!" You yelled, as Gaster grinned at you. "My Turn." He raises his SEVEN hands, and each hand let out a black tentacle (I HATE SAYING THAT WORD SO MUCH!!!). You tried dodging them, but one was able to crawl up your leg, and pull you down. The tentacle dragged you around the room, making your HOPE go lower, and lower by the minute. You yelled in pain, enough for Frisk to hear in the living room.

They look up from their phone, "Doctor...?" they ask, as they stood up from the couch. Frisk slowly approaches the hallway to the lab. "Doctor (Y/N)....? Are you alright...?" Frisk asks, as he heads down the hallway, eventually reaching the door to your lab, and it was open. Frisk takes a peek, and then silently gasps.

They saw you nailed unto the wall, by the black tentacles nailed unto your clothing. You hung your head, and Gaster let out a dark chuckle. "What... will I do.... to you... Subject 3...? And what.... would you do... if I... destroyed... all your... research...? So... much work.... WASTED. It would.... be a shame..." Gaster taunts you, as your eyes started to glow, you spat on his face. "Go burn in hell." You said, as Gaster grins, and places a sharp tentacle against your throat.

"Doctor (Y/N)!!!" Frisk yells, as you and Gaster avert your attention to them. "Frisk! Get out of here! Call Sa-" before you could finish, Gaster stabs the sharp tentacle on your stomach, letting the blood pour down, along with bits of dust. "Shut your... damn... mouth... Subject 3..." Gaster says as he deepens the stab, making you scream in pain, more blood pours down than bits of dust. You glared at Gaster, making your eyes glow. You look at Frisk who was terrified. You used your magic, to make Frisk float. "GO FIND SANS, AND PAPYRUS! HURRY!" You yelled, as the magic that you used on them, teleported them in front of Grillby's.

Frisk slams the door open, making everyone look at them. "Sans!" Frisk yells, and ran towards him. "Kid?! What's wrong?! Why are you here!?" Sans asks, as Frisk clutches on his jacket. "It's Doctor (Y/N).... She's in trouble... So much blood... So much... Dust..." Frisk couldn't speak between their sobs. Sans stood there in silence for a few moments, his white pinpricks vanished. His left eye flashed blue, the same blue that flashes on yours.

"Frisk stay at the Undyne's place. I'm going to get Papyrus." Sans teleports from Grillby's unto Undyne's house, leaving Frisk there. "Hey Punk! What are you doing here?! I'm in the middle of cooking spaghetti!" Undyne says, as Papyrus stops his cooking. "Sorry Undyne. Frisk will stay here for a little while... Me and Papyrus have matters to attend to..." Sans says, as he pulls on Papyrus' wrist, and leaves Undyne's place. "SANS?! I WAS IN HE MIDDLE OF TRAINING!" Papyrus yelled. "(Y/N) is in trouble." Sans said, as Papyrus gasped, and nodded.

As they arrived at your lab, the entrance was covered with black substance. "YOU DON'T THINK... IS IT HIM...?" Papyrus, had a worried look on his face. Sans gritted his teeth, and he fired his Gaster Blaster, making the black substance melt. His eye was flaming bright blue. They both run inside, seeing the black substance ruined your home. They both called out your name, and ran down into the hallway to your lab.

They stopped in front of the Lab Door, being sealed by the black substance. Papyrus uses his magic to cut the black substance, and they both burst into the room. Sans and Papyrus' faces drain, as they saw Gaster, and you on the wall, blood pouring out from the wound, while parts of your face, limbs, and torso, starts to turn into bits of dust. You were losing HP quicker than they thought. "Ah.... Subject 1 and 2... Finally.... Care to see... Subject 3... die...? I would... like to... see... your faces... once she dies..." Gaster says, as he lets out a dark chuckle. Papyrus and Sans, were fuming with anger.

Their eyes started to glow, and Papyrus charged his attack, while Sans used his Gaster Blaster. Gaster blocks them, and reflects the impact back at Sans and Papyrus. Sans used the Gaster Blaster head, to block the attack. The Blaster head breaks, and Papyrus, summons his Gaster Blaster head, and used it as a shield.

They both ran towards your body. Gaster then attacks the Blaster head, while Papyrus tries his best to keep the Blaster head from breaking. Sans uses his magic to remove the black tendrils. Sans carefully carries your body down, and then caresses your cheek. "(Y/N).... We should never have left you alone..." Sans whispers, as he heard the breaking of Papyrus' Gaster blaster head.

Papyrus was thrown back near both of you, Sans used his magic to protect the three of you. A Gaster blaster head, was the only thing protecting the three of you. Gaster shot a beam of darkness unto the blaster head, and it wasn't holding up too well. "SANS... I'M SCARED..." Papyrus whispers to Sans, while tears form in his eye sockets. Sans ducks his head, and let Papyrus hug him, "It's going to be over soon, Pap... We'll all be happy... All together... I promise, you and (Y/N)..." Sans reassures, as the blaster head breaks, and the black substance aims to the three of you.

"What a... wonderful.... reunion... such... a shame to... see you... all die... but...." Gaster raises his seven hands, and they all charged one final attack, "IT'S TIME TO DIE!!!". Sans and Papyrus closes their eyes, and waited for the attack, neither any of you could survive it at this state. The beam was going to hit you, Sans, and Papyrus, but before it could...

"What....?!" Gaster gasps, as Sans and Papyrus open their eyes, to see a huge Gaster Blaster protecting both of them. Neither Pap or Sans did it. Sans looks at you, seeing your hand raised up, your teeth gritting, and blood pouring out your lips. "(Y/N)!" Sans and Papyrus said in unison, as both of your eyes glowed. "S....ans.... Pa....pyrus.... I'm... so...rry...." You whispered, as you fired your Gaster Blaster at Gaster, making him vanish, and go back into the void. The Gaster Blaster's beam made a huge explosion, for everyone in the Underground to hear.

The black substance in your lab, vanished into dust. Your hand began to turn into dust, along with your legs. Your arm went limp, and you closed your eyes. Papyrus took a look at your HP. You were still losing HP. "SANS! WE NEED TO HEAL HER!" Papyrus yelled, as he sat in front of your body, making his eyes glow. He places his hands on your wound, while Sans hugs your head, and in the process of healing you.

Soon Frisk, Alphys, Undyne, Toriel, and Asgore arrived. "G-Guys! We h-heard an e-explosion! What happe-?!" Before Alphys could finish, she saw Papyrus and Sans crying. "M-My child...? Is she alright...?" Toriel asks in the verge of tears. Papyrus and Sans stay quiet, as they both try to heal you. "Hey punks! Is she going to be alright?!" Undyne yells, as she approaches, Sans and Papyrus.

Undyne sees Sans and Papyrus crying, with real tears. Sans and Papyrus couldn't heal you. "Please... Come back..." Sans pleads, as his tears stream down his cheeks. Papyrus cries his heart out, as he cried on his palms. Undyne pats his back, and sighs. Papyrus hugs Undyne, and she hugs back.

Sans hugs your seemingly lifeless body. "Please... I never had the chance to say... I love you..." Sans whispers, as one tear lands on your cheek.

Frisk takes a deep breath, and approaches you and Sans. Frisk bent down to your level, and places their hand over your wound.

*Knowing that (Y/N) can come back, fills you with Determination.

Soon, a warm red light shone under Frisk's hand. Everyone was amazed, but Sans. He kept his eyes closed, hoping that you would wake up, huggging him back.

The bright light subsided, and the wound on your chest stopped bleeding. The bits of dust, returned to your body, making you whole again.

Then Sans heard you breathe. Sans sat up, waiting for you to open your eyes. Papyrus checked your HP, and it was going up. You coughed, and slowly opened your eyes. Sans couldn't believe it. You looked around your surroundings, seeing that your friends were there, smiling at you. Papyrus and Sans, were crying.

Before you could say anything, Sans and Papyrus engulfed you with a hug. "(Y/N)!!!!" They both yelled in unison. You couldn't believe it. You were alive.

"Thank Asgore, you're alive! I can't believe it!" Sans said between the sobs. You couldn't help yourself. You cried as well, and hugged them. "I'm sorry, if I made you guys worried...." You whispered, as they just hugged you, with smiles on their faces.

-Time Skip (3 Days later)-

You have been staying at the Skelebros. house for three days, since your lab and home, needed to be fixed, and Asgore got it covered. He had workers to fix your home, while you recover from the pain.

You could still feel it. Once you fall asleep or not pay attention, you could feel something cut your torso in half. It hurts. While you were in the Skelebros house, you would always sleep with Sans in his room.

"Hey, (Y/N)..." You snapped out of your thoughts, as Sans joined you sitting on the couch. "Hey..." You said, clutching the blanket. "You still thinking about that incident...?" Sans asks, a bit worried. You bit your lip, and averted your gaze from him.

"I'm just scared... He might come back... And he'll hurt you or Papyrus... I don't want that..." You whispered. "Look, (Y/N)... You put him back to wear he belongs... And he will never come back, I'm sure of that." Sans reassures, as you clutch on the blanket more.

Sans sighs, and then pulls you into a hug, "Sans.....?" You ask, as Sans hugs you tighter. "I'm not sure if you heard me that day...." Sans pulls away from the hug, and places his hand on your cheek, "but.... Just make sure that I...", he leans in and closes his eyes.

"I love you..."

You stiffen, but then soon calm down. You kiss back, and wrap your arms around his neck, while he wraps his around your waist. He pulls away, and stares at your orange and blue eyes.

"You really love me, Sans....? I mean... I'm going to look like Gaster.... That old geek..." You said, with a bit of appearing on your face blush. Sans chuckles, and kisses your forhead. "Don't worry, (Y/N)... You'll always stay your beautiful and smart self..." Sans says, as you smile and kiss his cheek. "Thanks Sans... I love you too..." You said, as you leaned on him, while you fall asleep. Sans smiles, and kisses your forehead, before drifting to sleep with you.

-Timeskip (After a week)-

Asgore's workers, have finally fixed your lab, and you went back to work. You immediately worked on the formulas for Determination, but it seems as if you didn't need to anymore, you found out that, Frisk's soul, is the Soul for Determination.

Frisk was able to free all mosters, icluding you from the underground. You all stood there, staring at the sun rising. It was your first sun rise too, considering you are a humam hybrid.

Frisk and the others left you and Sans to be alone. It was romantic. Sans held your hand, and squeezed it. You squeezed back, and blushed. You stared into each other's eyes, with fainst blushes on your cheeks. "Oh my god! Would you guys just smooch already?! The audience is waiting~!!!" Mettaton exclaims, as you growl at him.

You were about to chase him, but Sans intertwined your fingers, with is and kissed you. You kissed back.

There was a spark... A spark that you felt... And it... Felt like...

You were... Glowing.

~End~

(What a shitty ending!!!)
