Sans x Reader AU Oneshots

Sans x Reader - You knew him?

In this one... You will be a human who fell with Chara, and you had seen Asriel die. Afterwards, you resented humanity, just as your friend had. You wanted revenge.

You didn't stay anywhere. You had been lost to legends. You were a lost soul, wandering and scared to show yourself.

You shuddered, your eyes being blinded by the light. The surface had just been opened. By what, you didn't know. But you did know a skeleton was looking at you. You were invisible to monsters, so you backed away.

"Kiddo, why're ya walkin' away? I can see you, ya know?"

You froze. "But... I can't be seen by anyone! How do you see me?!"

"You're a lost soul... aren't you?"

You nodded hesitantly.

"Well I'm Sans. Sans the Skeleton. Nice to meet you, kiddo."

"Call me (Y/n)." You smiled.

The next day, Sans had gotten Alphys to see you. She had machines that could allow her to see you, and so she worked on a way to help you.

In the meantime, you saw a gold flower in a pot. You walked over, looking at it. The flower had a sullen expression, and you recognised it. Well, sort of, anyway.

"A-Azzy?" You asked quietly. The flower jolted, looking at you in surprise.

"(Y-Y/n)?!" The flower exclaimed.

You smiled, nodding, "Hey, brother... how've ya been?"

"I... Aren't you dead?!"

"No. I thought you were though, Asriel."

"I have no soul... so, technically, I am... Also, I'm Flowey in this form... but... You... How?!"

"I'm a lost soul... I still hate humanity... they killed you..."

"..... Not all humans are bad..."

"Coming from you?! You were stabbed by them! I swear, I will get revenge!"

You began to glow, and suddenly, you weren't a lost soul anymore. You were in your old body.

"(Y-Y/n)... Look at yourself..." Asriel, or Flowey, looked in worry.

You looked at yourself, "I... I'm back!" You smiled, twirling.

Sans looked at you, and gasped, "(Y/n)?"

Alphys heard the name and gasped, kneeling down. "Y-your highness!"

You blinked, "Wait... so you know me?"

Alphys nodded, "I am the r-royal scientist!"

You tilted your head, "What happened to G@$!&#?"

Alphys tilted her head, "Wh-who?"

Sans looked at you in surprise, and pushed Alphys away. He smiled in an apprehensive manner. With that, you, Sans and Flowey left, Sans holding Flowey's pot in magic.

"So, this is Asriel?" Sans uttered.

"My figurative brother. Right Azzy?"

Flowey scoffed, "You know I hated that nickname, (N/n)."

"I know... Azzy..." You smirked.

Sans chuckled, "More like true siblings. Anyway, who was the first human in the legend?"

"Her name was Chara. She... was another sibling. She was a best friend, like... a sibling, but not... she had some sort of obsession with knives..."
