Summary
"They’re sitting in a bed of golden flowers somewhere far beneath the earth, and, as far as they can tell, for better or for worse, they’re decidedly still alive."
_ _ _ _ _
Frisk climbs a mountain and inadvertently awakens an ancient terror sleeping beneath the flowerbed they land on when they fall. If by "ancient terror" one assumes the less-popular definition of "annoying narrator-ghost princet of monsterkind who is now, unfortunately, permanently stuck in their head."
Chara doesn't want to be awake. They especially don't want to be helpless in the back of a bloodthirsty human's head, watching them ruin the only home they've ever known with no power other than their voice to fight back with. Luckily for them, that's not what's happening at all. Unluckily for them, they may have to re-evaluate a few things about their worldview. Which, for someone as set in their ways as them, is not an easy thing to do.
(Then there's the matter of the weird flower, Frisk's unusual powers, and the Longest of Long Days the underground has ever seen.)Chara & Frisk no player AU true pacifist. Updates Thursdays & Fridays!

Summary
Frisk lights up as they slip through the door.
“You came!”
Chara sighs, and shuffles over to slam the pretty-people-discount coupon on the counter. What a stupid little slip of paper. But, a discount is a discount, and 75% off is a downright steal with how much people tended up mark up flowers around this time of year.
“Just something to say ‘I miss you’ for Heir’s Return tomorrow.” They mutter.
Or
fluffy charisk bullshit tattoo artist x florist au! with a little angst to taste, and chara and frisk being foils, because what’s more romantic then being each other’s foil characters?

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
“Not so fun being stuck in some loop right? Trying to fight to protect what ya got, not getting a choice in it. If I had the choice I wouldn't remember either.” The words oddly felt comforting. Link let out a slow breath, closing his eyes for a brief moment.
He didn't feel alone for the first time in a long time.
And that?
That was terrifying.
“To be honest, I kinda gave up a while ago. Just sat back and let the chaos go on, felt like nothing I did mattered anymore. Everything would just be reset anyways. Stopped caring what happened, that was until you showed up.” The skeleton’s eyes bore back into the Hylian.

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
After leaving the underground, monsters and humans are finally at peace...or it would seem so, as conflicts arise: Will everyone be able to overcome past conflicts and move to the future, or will they divide once more? It's up to Frisk, who is perfectly fine and is totally not going through an identity crisis that is totally NOT your fault, to solve!

Summary
When Frisk doesn’t show up for breakfast one snowy morning in Snowdin, Papyrus immediately assumes the worst — dramatic rescues, tragic collapses, or possibly melting. Sans suspects something simpler: the kid just caught a cold. But when a pale and sniffly Frisk opens the door, Papyrus’s heroic instincts go into full overdrive. Blankets! Soup! Emergency hydration protocols!
As Sans teases and steadies his brother’s chaotic caretaking, the two skeletons realize how deeply they’ve come to love the small human they’ve taken in. Between Papyrus’s “miracle soup” (which somehow turns out edible) and Sans’s quiet reassurances, Frisk drifts to sleep surrounded by warmth, laughter, and gentle love.

Summary
Fighting against royal nepotism,
Stood 4 humans who died for monsterkind.The first was the patient of spoiledness,
Who planted the seeds for action.
Then came the revolutionary,
The brave soul who died for the cause.
Don’t forget the human who stood on their values,
Whose silent perseverance was idolized for resilience.
At last was the giver,
Their kindness to the unkind led to their demise.The fifth, the enforcer of justice.
With the revolutionary seeds in the soil,
Born with a soul so determined,
The others sat for him so he could stand.
---
A world where Chara and Asriel weren’t able to go through with their plans, yet the royal family continued on a murder spree. For each human who fell, the underground saw them as leaders of revolution, only for that hope to be stripped by the monarchy. How would Clover be different from the others?Navigating through the complex relationship between the crown and the underground, Clover and Frisk set on a journey to liberate monsterkind, using everything they could to bring justice against royalty. But when one man serves as the judge, jury, and executioner, how fair can justice really be?

Summary
The Multiverse isn't as unreachable as one might think. Sometimes, all it takes is one aware person to tip the scales for another to find out about it. But when one isn't ready for it, returning to their own world is relieving and best for the psyche.
Humanity's thirst for knowledge is near insatiable. How far would they be willing to go to learn more about their new magical coinhabitants on the surface? How far would they go if they could weaponise their magic?

Summary
A mutation has spread across the globe when monsters were released, humans either dying as their bodies couldn’t handle it or mutated with the rest.
The mutation was simple really, a change of dynamics. Humans started taking more unusual forms, growing more than a few ears, eyes, arms, legs, shit even a head at one point. Or body morphing differently altogether. Turning into their worst nightmares.
Y/N being a young child at the time of the outbreak changed with the rest of her family, half of her family died or killed themselves resulting in her being an Orphan at a young age, left alone in the world as her body shifted and changed. Body becomes leaner, smaller…cute. Cat-like ears and tail sprouting from her body, legs breaking and reforming into back hind legs of a cat's, fur covering her legs stopping at her waist.
Not only that, but she is an Omega.
Of course she doesn’t know oh no no no blissfully unaware, well that is until an over caring human Frisk decides to visit the Orphanage dragging along her friend Chara. Whom in turn absolutely dreads the visit. Let's say…frisk was the door to meeting a rowdy group of skeletons…

Summary
The slashing of Undyne’s spears ended their 342nd run. The world faded to black and the death screen showed. A scream echoed from a deep hole in the cave, curving reality to the present as the wilted yellow flowers bent around the now grown child rolled around in anger.
