"Hey, little pup?"

"Sans, I'm 18 years old now. You don't have to call me 'little pup'"

"What do you want me to call you then? 'Little boss'?"

"Really? Sans, you just mixed the two names I don't want you to call me"

"Oops, sorry..."

"Just call me Frisk when Toriel and Asgore isn't around"

Hungry Love (Horror Sans x Reader ) by YandereEmo

In the midst of Tokyo's bustling streets, you led a life that appeared ordinary, despite your role as a leader in a prominent gang. Yet, beneath the façade of normalcy, you carried the weight of profound loss-your mother, your father, your brother-all taken from you, leaving behind a void that seemed impossible to fill. Determined to shield yourself from further heartache, you resolved to protect the one remaining person you held dear: Frisk. Their presence brought light into your shadowed existence, offering a glimmer of hope amidst the darkness of your past. But fate had other plans. The dissolution of your gang shattered the fragile stability you had built, leaving you adrift in a world that suddenly seemed hostile and unfamiliar. Yet, in the aftermath of this upheaval, you found solace in Frisk's unwavering companionship, their presence a beacon of comfort in a sea of uncertainty. Then, in a cruel twist of fate, you lost Frisk. Cast into the unfathomable depths of the underground, your path collided with Aliza's, a chance encounter marked by the ominous presence of Horror Sans. Emerging from the shadows, his hollow eye sockets bore into your soul, his grin sending shivers down your spine-a chilling reminder of the darkness that lurked within the depths of the unknown. With each loss, the world seemed to grow colder, more indifferent to your struggles. Yet, amidst the despair and desolation, a glimmer of resilience flickered within you, a quiet determination to reclaim what had been taken from you, no matter the cost.

Taking cover <Frans> by Battle_Penguin54

"I'm telling you! She died in a fire 7 years ago!" I boomed and raised my hands up in the air. He was sitting calmly, in his chair and leaned over onto his elbows in a discreet manner. "Well, According to what we have just witnessed today, that is most certainly untrue." He growled lowly, "She is a threat to the MMO, and everyone in it." I stayed silent, I couldn't believe that she was actually alive, all this time, I could have completed that lousy task and been done with this ordeal. "Well, what do you want me to do about it, Asgore?!" "Find her, and kill her." He said harshly. "You're one of the best fighters in the Mafia, Sans. Don't disappoint me this time." "Yes sir." "Actually.." he stood up, a smirk on his face. "I have a better idea."

666tale (charisk au) by scented-candle

Determination. A trait all humans are born with. But in a great quantity, determination can give a human life changing strength. Such as the ability to reset an entire timeline. Power like this put into good hands can have its advantages. But power like this could also corrupt anyone. Even the most humble of people can become a beast when handed this ability. Determination can create a monster. And not the kind of monster you would want to befriend. (warning:this includes major spoilers for the game undertale,and I recommend you to play the game,or watch someone play the game before reading this fanfic. In this story,Chara is a girl and Frisk is a boy. If you don't like charisk,or undertale,then please don't read,and don't complain.) Tw:this may include self harm,attemts at suicide,blood/gore,and some foul language Cover art is by me I hope you guys enjoy,I'll try to update whenever I can!

Sans X Frisk (An Undertale FF) by Turtleluv42

After Ethan (Frisk's older brother) broke the barrier and set everyone free, they went on a huge trip around the world to spend more time together. Frisk had no time at all to talk to her friends and to top it all off she had lost her phone on the first plane ride. Her and Ethan decide it's a good idea to go back to where all of her friends live after over a year of traveling. Frisk was so excited to see her friends again. Especially Sans. Before she left they shared their first kiss and she said that they could work out a long distance relationship but it didn't work out since she had no way of talking to him. She just hopes that they can become closer after not seeing him for what felt like forever. Most of this story will be in Frisk's POV but I might change it around sometimes. Frisk and Sans are about the same age and Frisk is a girl. Chara will be in this sometimes but she's not a genocidal maniac. Also Asriel is in this as well and Flowey was never a thing. One more thing. This will have some curses in it so if you don't like that, don't read it. Anyways, enjoy!

Little Things - Sans x Frisk by DragonzRawesomE

But instead, she awoke Underground, and found herself in the hands of creatures she had never imagined in her wildest dreams. She begins on her journey through the Underground, coming across some unexpected new friends along the way. One friend, in particular, is there to guide her along the entire way. But when her mind is enveloped in a prison of darkness and her Determination seems to have disappeared, will she be able to pull through just in time, with him by her side? Or will she fade from existence, just as the seven humans before her? DISCLAIMER: UNDERTALE is owned by Toby Fox. COVER IMAGE edited by me. I do not own the original image.

Moon Light - Undertale fanfiction (FriskXSans-not the main plot tho) by Ombre0

Intro: The barrier was down. It had already been four week. Most of the humans were not pleased with the monster arrival, but since Mont Ebbot was a bit far from the city and that no one ever goes their (for most part of the population at least) they allow the monsters to rebuild their society on it and around it as long that they keep their self far away from the city. With their magic it only took a few days for everyone to be set .It was a new start for monster kind, now they would only need to make their relation with the humans better. Everything was for the best; well it was until the little human that had free the monster got her secret exposed. --- -A/N- -Undertale and all of it's characters belong to Toby Fox -My first language is not english -Frisk is a girl in this story -I don't know when I will be abel to update but I will do my best to not be to slow -Don't esitate to give me some feedback it's my first fanfic :) ---

Mafiatale - Living Life Among Crime [Frans] by SepticGirl88

Sans. He is a serious skeleton who is part of the Mafia, and he doesn't like to take shit from anyone. Well, maybe apart from his own boss, Asgore. He can't really say no to him. Especially when he is set out on a mission with Asgore's son Asriel to catch a Mafia traitor. However, a strange girl decides to get in the way, and Sans feels like his life is going to become nothing but more frustration when he is told to look after her. There's not really a lot to be known about the girl. Except that her name is Frisk, and she doesn't seem one to like the idea of killing. But there's always the chance that might change when she begins to live among a dangerous group known as the Mafia. The art for the cover isn't drawn by me! (I wish I was that good at art! xD) The original art can be found here: https://rebelgirls.deviantart.com/art/Mafiatale-Frisk-668373673 (I think the drawing of Sans got taken down but if I can find it I will link it here!)
