Prologue

(A/N): Contains spoilers! I suggest you either go play Undertale or watch Rise of the Guardians before reading.

Undertale belongs to Toby Fox and Rise of the Guardians belongs to William Joyce.

He remembered fighting, his father falling into the CORE, his brother dying. Sans remembered everything.

He then remembered, the resets.

Sans died so many times. No matter how many times he killed Chara, they always came back.

He was tired, so tired. Nothing mattered anymore.

"welp."

A red liquid trickled down his jaw as he clutched his rib cage.

Sans…

"i'm going to grillby's."

Chara looked down at him with a smirk as if he was only an ant that they burned with a magnifying glass.

I need you.

Sans could feel his body slowly crumbling into dust. But he stood up slowly, and staggered away from the demonic child.

Just relax, please calm your mind. Do not fight.

"papyrus… do you… want anything?"

Sans then fell forward, fully crumbling into dust.

(A/N): My first fanfiction ever. I really like Undertale and Rise of the Guardians. Please leave a favorite or a review. Those fill me up with DETERMINATION to keep writing. Anyways, I hope you enjoyed the prologue!
