FRISK GETS THE FLU SND NOW EVERYONE IS WORRIED
(LET ME KNOW UR THOUGHTS AND IF I SHOULD CONTINUE TO UPDATE THIS)
-
Tags
Summary
Long ago, two races ruled over Earth: Humans and Monsters. Religion and fear of differences troubled the fragile peace on which both species were living so far. A war for faith and honor soon engaged between them. Long. Endless.
Sans and Papyrus, two young skeletons brothers, sons of the Royal Scientist, lost everything in the rage of the fighting: their home, their family, their childhood. During a human attack, they suddenly found themselves delivered to bullets and bombs, all alone.
Both of them started a journey in the devastated landscapes of the end of the war to join Mont Ebott, where Monsters are preparing for a last battle. But could two kids survive by themselves in the wild and without any help?

Summary
Izuku was still only a baby when his sister was born, so he had never really known a world without her. The only evidence he had ever been an only child at all was a single album of baby pictures, ended with one of a 14 month old Izuku wearing a onesie that said ‘best big brother.’ To Izuku, the world had never existed without Frisk.
So when she suddenly vanished years later, it took everything in him to not let the world shatter.
+x+
Izuku Midoriya was born without a quirk, later he came to the conclusion that it must be because it would be unfair. That someone had to be quirkless to give Frisk such an amazing power. A power to return to the past to change the future. A power that even supersedes death. His knowledge of that power is what he clings to, because his sister is not dead. She can't be.
Frisk Midoriya was born with quirk that scared her. Sometimes she wished her brother had gotten it instead, he was so much better at adapting. So when her untimely fall puts her in the position to save an entire kingdom, she steps up to be a hero just like Izuku. Even if it kills her- even if kills her over, and over, and over again.

Summary
Twenty-five years ago, a farmer took over her grandfather's old farm and turned into one of the most important farms in the Ferngill Republic.
You are her child.
You know the farm and the Valley like the back of your hand, having been raised in it your whole life. But now, with your parents going away for important business, the farm and its responsibilities fall onto you. Sure, maybe there is a lot of new weird stuff happening in the Valley that started as soon as they left and you were holding it all together with the skin of your teeth, but you got this! Totally. 100%
That is, until you turn on the TV one morning and it tells you that your little sister friend Frisk had broken a barrier and was now an ambassador to a bunch of monsters. Only for said monsters to drag you into their shenanigans and problems.
What could go wrong?

Summary
"Resets", which you only actually learned about this morning, were a freaky time phenomenon which allowed something to travel to the past repeatedly. That "something" was a human, and that human wasn't actually human at all. That was what your journal explained to you.
(Or, Sans doesn't remember the resets, but he knows about them and he has to deal with it.)

Summary
It was bright. Too bright, what had just happened? Flickers of memories passed through Sans’s mind in a whirl. “Doctor Gaster!” He heard a faint scream. It was muffled under his own screaming of his mind.
“Someone get the kids out of here!” Another voice said. The bustle around him felt as if it was going in slow motion. The colors faded from his vision as he collapsed onto the floor.
“Brother! Wake up!” A small voice peeped. Sans felt his consciousness fade. The nausea he felt was too strong, and he welcomed the darkness.OR
Sans is left to care for his rambunctious younger brother Papyrus, his health suffers as a result of overworking. On top of that: memories of the past plague his dreams. Sans must work to overcome his trauma while also allowing himself to be supported by those who care for him. Tags to be updated as chapters are released.

Summary
A collection of connected and unconnected one-shots (Even the unconnected ones will reference others), requested in the Discord Server and prompts that I wanted to explore further. One-shots will be of both Merging Timelines and Multiverse Madness, and each chapter title will show which story it's from! There may also be AUs of Merging Timelines and Multiverse Madness in here, and those will not be Canon to either story line. Also, not keeping the fonts for the MT boys, so them being missing isn't a mistake or anything in case you're wondering.
Note: The one-shots have random lengths. Some will be as long as a chapter, and some will be shorter. There will also be multiple parts to some one-shots too, depending on the plot.

Summary
Not that he would ever directly say so. He isn't very good with words in that regard, but...
His brother is his whole world.
A few tears on his own part would never be anything, if he could trade them in just to get Sans to smile.
