Summary
Frisk has always been good at dodging and always been able to take a hit, but what if there were a different reason for that? What would happen if Frisk had to adapt to an abusive life when they couldn't feel pain?
Frisk dodges like it's second nature, avoiding most attacks easily. As for the attacks they can't dodge, well how much of a threat can they pose if none of them are fatal? Frisk just needs to make sure to care for them afterwards...

Summary
You've all heard, seen, or read it before. The Barrier breaks, monsters are free, the game is over...
Sometimes, you RESET because you haven't had your fill of their world...
Sometimes, you try something new, just to see what happens...
Sometimes, you kill...
But it's still a finite connection, isn't it?
Eventually, you will have something better to do. There's no helping that.
...but what if someone didn't?
What if someone kept going? Refused to give up? Obsessed over every possibility?
...
What if they were determined to find a way to see more?
They become so entranced with this world that everything around them fades out...
...until it's all...

i'm rootin' for ya, kid (2023 Reboot In Progress) by Cat_On_A_Keyboard, Sneakyfox55
Fandoms: Undertale (Video Game)
11 Dec 2023

Summary
Sans had gotten used to them resetting after a while. Eventually, it became almost a routine of sorts: they’d get bored half-way through, RESET, and redo everything all over again, whether they chose to show MERCY or FIGHT that time. Sometimes it was after getting monsters to the surface, other times it was before. It seemed they were never satisfied.
But one day, things are different. One day, they fail to appear like they always had; in their place is a ghost, similar to them but far more different. They claim the other has disappeared, without so much as a trace.
And Sans is left to wonder if he’ll ever see the kid again.
He's not sure he wants to... -

Summary
Long ago, two races ruled over Earth: HUMANS and MONSTERS.
One day, war broke out between the two races.
After a long battle, the monsters were victorious.
They sealed the humans underground with a magic spell.
The humans, unable to accept their loss, began their efforts to break the barrier that kept them trapped underground. They found that no natural human soul could bypass the barrier on its own. One day, a leading scientist posed the theory that a modified human soul may be able to bypass the barrier and destroy it from its source. And so our story begins…
