Undertale was created by Tobyfox. This guy is a genius and i only use his characters.

3rd Oneshot of my serie about AUs. Now i've made the 3 main AUs.
Once again, i've still not corrected this so if you see any mistake, comment and tell me please.


It is the best day of his life. He hug his perfect wife and looks at his perfect little bone. Finally he is a dad! He wants to scream to all of the Underground the good news!
But for now all he wants is to spend time watching over the newborn. He is so cute! He's perfect!
In his mind, he already is planning the future of the baby. Obviously, he'll be brilliant and strong like his father! He could be the next Great Knight! He'd need training for that. Like always, he start to talk too fast to his sleepy wife. Explaining what he want for their son. Soon she fall asleep and he pick the baby in his arms.
"Hey! Hello you, it's me! Your papa! You're the cutest thing in the world. I know you have low stats for now but you know what? Forget what the Doctor said. I know that with training and a lot of love, you can improve. You'll be the happiest and greatest monster ever, I promise."


"Come one Sans! It isn't that hard i know you can do it!"
Every Time he hears his dad say those words, he feels his soul coming full of joy. He loves the attention. He crave this and everything he want is popularity. He already is the number one in his Dad's heart. Now he must win the rest of the world's love.
Dad wants him to be the next Great knight. His friends at school told him that the Knights were a thing of the past. Now everyone looked upon the Royal Guard for protection against humans. But he know they're wrong. After all, Dad is the last Knight and the strongest monster ever! With his help, he can go over his little HP problem. He already got his Defence and attack rise up from the training but his HP are still at one point.
His father encourage him to the newest exercise to try to fix that. After all it can be fix. Dad say it all the time.
But not Mom. Sometimes, when he's too excited to sleep, he hears them talk. And she's upset, often. He could say all the time. She say that it's never going to fix itself, that only EXP, he wonders what she meant by that, can improve one's HPs. But she's wrong! He know that because Dad always say it.
Mom said one day that Dad was in denial of the problem. He never knew Dad could be that angry.


"Put that down! Put that down!"
He was upset. How Dad dares to hold someone else? A baby Brother? He never wanted that! He wanted his Mom!
Why Mom wasn't there anymore? Dad told him she was in vacation. He wanted her back! The baby could go on vacation! But not his mom!
So he cries, he scream, he do everything he know that always makes his parents change their mind. But no. Dad keep the baby in his arms, he cries. Dad never cry.
What's going one? And the Baby cry too loud, it hurt the skull!
"Dad put that down now!"
"It not a That. It's your brother, Papyrus. Your Mother loves him very much, as much as she love you. So please, take care of him while she's away. Can you? She'll be so happy."
He pouts. He don't like this. Dad get one one knee and show him the baby closer. He still cry too loud.
"Come one, say Hello."
He hardly hear his day talk because of the baby. But he want Dad to look at him and to praise him so…
"HELLO PAPYRUS!" he says with a large smile.


It's not normal. He don't like it at all. He watches as his brother grow, he's not very tall. In fact, he is too small. Sometimes he read the growth chart for a skeleton in the old books in the library. And Sans is way below average.
He asked his father once about that. He told him that Sans was a very special and perfect Skeleton. Special, he agreed. His brother was the coolest ever. But perfect… He could write a whole book about why not.
First, his attitude. Maybe he was only eight but he could see his brother was selfish, childish and full of himself. But he could blame Dad for that. Always praising Sans, never scolding him for his bad behavior and giving him all he wanted.
His big bro was a spoiled brat… a eighteen year old brat.
Second, his naïveté. His brother was not stupid, he knew that. But he was too naive for his own good. He still believed in Santa! And himself knew about Santa last year. Dad's told him to not broke his brother dreams. He agreed only because he loved Sans so much.
And then, there was the HP problem. Skipping some classes, he knew that HPs were importants and only sleeping in a comfortable INN of gaining Levels of Violences could increase one's HP. Still, Dad trained Sans to believe that the problem will go away one day. It couldn't be true. And it was dangerous. What if a human comes by and attacks his big bro? Yes, his defence is high but it was worrying.
He tried to talk about that to Dad, about his fear to loose his bro but… It ended with more problems.
Dad broke in front of him, no more in denial and showing him a strange device Gerson made. A device used more than once to keep Sans alive. Now, he checks twice to know what day it is. And when it's the same as Yesterday, he knows his brother was hurt.


He stopped. Stopped caring about anything. He relived the same day for the… what was it? He lost the count after thirty six. And yet Dad never gives up.
He just wants for it to stop one way or another. And he know Dad want that too.
It began with his wake up to this stupid music. Then Sans come into his room excited for the new day and force him to go out from bed.
Then it's breakfast, with tacos. He stole a bottle of honey, to help him with the day.
Then there is the alarm. His Dad come and tells them to stay inside the house. Sans disobey, knowing he will never be scolded for that. He follows.
They find the Human, they fight and Sans is hurt. He dies and he kill the human with the Blasters. Dad come, use his device and he wake up again, and again, and again and again…
They tried everything. Locking the door, distract his brother, go away in another place… He even knock him out once but he dusted anyway. He was too strong for his brother.
He hated his father for that. It was because of his parenting if his brother think he can capture a human alone! He won't listen to reason, because he's the Magnificent Sans, Royal guard in training and soon to be knight.


It's over. This time; he did it. But at what cost?
He looks at his brother's sleeping form on the couch. He never seen his sibling so tired before. And yet, he didn't have any memories.
So he goes to his room, leaving his brother get his sleep. Once alone, he shakes and cry. He can't do that in front of Sans. He stopped caring so why does it hurt so much?
He remembers everything. Finding the human first, sending him in the wrong direction. And Dad…
He could still hear the skull cracking, the explosion of the machine and… Nothing. Gerson couldn't remember. He was alone, more alone than ever.
He's scared to sleep. He takes the first paper he found, an old drawing, even on it, his father's face was fading. He takes a large red pencil and writes: Never Forget.


I didn't have many idea for this AU. For me it's one of the weakest one if we don't take liberties with the characters.
I like it anyway. It just need to focus less on Sans and Pap. (I know it's ironic after reading the story but I'm searching for more depth in this AU)
Thanks for reading, it's been nice to write in english for once.
And if you have an AU you'd want me to write about in this Fatherhood serie, don't be shy and ask me, it can led to some interesting stories.
