Summary
Disoriented and emotionally frayed from decades spent in the void, W.D Gaster suddenly finds himself at the mercy of a cold and arrogant alternate self. His doppelganger promises to return him to the void once his research is complete but before he can make good on his threat, Gaster is introduced to this world’s variant of his son and he is forced to make a quick, spur of the moment decision.
This sole act sends unforeseen ripples throughout the Multiverse and hurdles Gaster on a perilous journey across it to find his way home.
or
Dadster plays hopscotch across the multiverse, unintentionally and intentionally acquires children, tentatively reciprocates Grillby's feelings, engages in actual literal custody battles with copies of himself, somehow steals a Bad Sans™, narrowly avoids death at the hands of Error and somehow flies under Ink’s radar for a shocking amount of time.

°*⁀➷ YANDERE OCTOBER 2025 ; DAY 2 — DAYDREAMER ┆彡
Then Killer starts imagining.
He imagines running away from the big boss and finding his way back to you. Then you'd nurse him all over again, and he'd flirt with you this time, letting his intentions be known.
Or maybe he finally gets rid of Nightmare. Free himself, perhaps the other Sanses too if they weren't so fucking miserable, but alas, free.

Summary
The year of 194-.
The 1940s were not a great time for many people, and those people also include a certain family; Klaudia and her family were immigrating, in the hopes of not being caught and put into the worst fate imaginable, only that, with curiousity, Klaudia found herself slipping and falling inside a wretched hole in the mountains of which her and her family had set up a hiding, never to be seen again.. by humans, that is.
The underground was in a crisis, its weather and resources were in a dangerous stage, and the monsters had become desperate. And desperation leads to rage, and rage to violence, and they knew they needed one more soul, a single other soul to finally escape their confinement underground. But they were also smart, theyd play their cards right and try to fool the poor girl to falling into the beartrap, earning her trust, however.. she was, too, as smart as they.

Summary
Frisk, a child who previously gave up on living due to having a hard time on the surface, falls into the Ruins. After spending time in Toriel's care, they find the strength to go on. To them, this means they need to leave the Ruins. After facing their first death during a confrontation with Toriel, they address the elephant in the room (or rather, the extra human in their brain): Chara. Chara has no memories of their life and no motivations in particular, but as they get to know the other human kid that they're stuck with, they can't help but get attached. Frisk reminds them of themself, somehow, as if they were two sides of the same coin.
Together, they traverse The Underground in their now shared body, meeting foes, friends, and foes turned friends along the way. Despite having previously considered themselves good as dead (or actually dead in Chara's case,) they find their hearts crying out that they want to live, no matter what that ends up meaning to them.

Metamorphosis - Alternate Title: Equally Unfair Circumstances by Rando_internet_Guy

Summary
Frisk has been through a lot. The Underground was quite the journey, with a race of monsters that wanted them dead and an unknown malicious entity that had possessed them, and after a run they'd rather forget the entity is gone. Now, they and Chara are busy trying to help monsters integrate with humanity.
However, there is a reason Humanity doesn't know about magic, and that reason is keen to keep magic away from Humanity, with the belief of the ends justifying the means.
Opposing secret organizations, overseers with plans of their own, finding themselves in a situation where a single kid overturns the status quo that has reigned for decades. A kid that simply breaks all previously known rules.
However, every will can be broken, no matter how strong. So, the Willbreakers lock and load and are sent to handle the threat, with the goal of eliminating the anomaly. And so far, they have done a good job of keeping Frisk firmly in step one.
However, in a distant universe, a human has made a promise to an entity that wishes to compensate for its actions, and through the creation of a Dark Fountain they are now here.
This wasn't how anything was planned, but it will surely be very, very interesting.
