Summary
It's been three years since you fell into the underground and found a family among the monsters of the Ruins. You love your life here with Mom, your ghost buddy Blooky, your prickly friend Flowey, and the host of Ruins monsters who have accepted you as their own, but things can't stay this way forever. Your friends deserve to see the sun, and there's a prophecy to be fulfilled and a barrier to be broken. Your determination pulls you onward.
The only trouble is that you'll have to make it through an underground full of monsters clamoring after the red SOUL in your chest, and each day as circumstances become more dire they lose a little more hope. This is a more desperate underground than the one you landed in. The odds don't look good for one pacifist child with a stick.
Of course, you aren't completely outmatched. You've spent the last three years training for this moment, and you don't intend to let anyone hit you.

Alternative Title: I Found Myself In An Isekai Styled Game Of A Game I Barely Know
How’d I get so lost that I found myself in a different dimensional plane?
—
“why is it… every time i see you, your flavor text is always written as ‘confused’.”
“… It’s my default….”
“i find it funny how you sound both confident and confused with just that.”
—
Basically you fell in the middle of the Underground and you just remembered this is a game you played once and never thought about it again. No amount of isekai mangas, reincarnation manhwas, and magical manhuas could ever prepare you for what you should do in situations like these. Because honestly, the fact that you know absolutely nothing outside of playing the neutral route was already a disadvantage.However, you can’t remember if there was an element to the game that included the enslavement of the whole monster race after they got out of the Underground.
Nor can you remember that there was any sort of color to the status windows that keep randomly popping up out of nowhere. Not that you were complaining since these status windows are what keep you alive from this… chaos…

Summary
Spanning over ten years, this huge fic will be split into ten parts for each year.
This fic is Alphynecentric, with Alphys at the helm. This is a fic that came outta nowhere (as they all do) and hasn't quit since I started. I have no idea where this will go. All I know is that it is very emotional, romantic, and rather silly.
Just enjoy. This may be my last fic for this fandom.

Summary
Frisk hadn't exactly intended to fall, and certainly not the way that they did. They weren't exactly opposed to dissapearing, as they'd heard could happen on the mountain, but now that they knew where the kids all went they felt a little overwelmed, and alone. Maybe it was a mistake to climb mount Ebott. But then they meet people, monsters, nice ones that care more about them than the people on the surface. Maybe dissapearing was better than they thought.
I just wanted to have some fun and rewrite the events of undertale with more emphasis on Frisk and what led them to the mountain in the first place. I'm just trying to have some fun writing. Also I make Frisk non-binary in this.

Summary
She turned and ran. Her mind was screaming at her. GO BACK, and fight! Dad and Papyrus did! I sho- I SHOULD. Maybe… maybe this is a dream. Maybe I can wake up. Maybe they’re not- maybe they're not dea-. Her thoughts screeched to a halt, as did her body. She stumbled forward a couple more steps, then stopped. She was underneath a huge fir, covered in snow and offering shelter, comfort. She pressed her back to the tree, and slowly slid down. She didn’t know what to do. She pulled her legs up to her chest and buried her head in them. She stared at the snow between her feet. Everything was coming crashing down on her. Everything that had happened. She felt sobs bubble up and let them come.
Tears dripped in the snow, melting it slightly. She knew the truth. There was no way it wasn’t true. They’re gone. They’re gone. I’m- I’m alone. I couldn’t do anything. I couldn’t save them. I couldn’t even fight for them, like they fought for me. She figured the creature would come after her eventually, but she didn’t care. Maybe she’d get to see her father and brother, if it did. She curled in on herself and cried.

Summary
After countless resets and endless repetition.. something has changed. The timeline has began shifting, changing its path for the first time in a long time. A new path Flowey hasn't seen before.
Well, it might take Clover longer to reach Asgore but Flowey has all the time in the world after all. And seeing something new finally happen has piqued his curiosity. Drawn in by the unfamiliar, Flowey watches with morbid fascination as Clover is not able to give up his soul this time. Encounters shift, monsters react differently, and the world itself begins to remember things it was never meant to.
Events shuffle. Characters act out of turn. Rooms appear where there were none. And for the first time in countless resets, Flowey doesn't know what comes next. Clover's fate is uncertain. Though Flowey knows he will get those human souls, no matter what.

Summary
“Thanks, Paps.” Sans replied, taking the blanket and dropping it over the sleeping human. Proceeding to give the child an affectionate pat on the head. The sight made Papyrus think of when he and Sans were younger.
Seeing his brother in such a state filled Papyrus with his own feeling of euphoria. After all his brother has done for him, even including all the times he has annoyed him with the puns, Papyrus felt that Sans deserved his own bit of happiness. His own chance to have the life he wants.
Or essentially five times of others witnessing Sans acting as a Father towards Frisk, the one time he admitted it.

The dust that never leaves his hands. The echoing voices that never stop.
When another human finally falls into the Underground, Sans expects the game to continue. But this one is different. Against his better judgment, he hesitates.
Mercy is a mistake he can’t afford.
