After waking up in the body of the protagonist of Undertale. The newly named Frisk has to find a way to deal with the consequences of actions he doesn't even remember taking. And find a way to not only save the underground, but also himself.

After freeing the monsters from the Underground what's next for young Frisk? Well, there's always the world's most popular trading card game Duel Monsters. With a deck based off of her adventures it's time for the monster ambassador to show everyone what she's made of. Though with dark forces around every corner, she'll need to remember one thing, always stay determined.

Time. Space. Reality. It's more than a linear path. Far from the Remnant you know, there are infinite others, each only a fraction different. Here, we see the results of an astronomical fluke. One that granted a child the powers of the most powerful Monster who ever lived. I'd say more, but you know what they say. It's rude to talk about people who are listening.

It's midnight in Castletown, and Frisk and Ralsei are asleep on the couch, using Susie as a pillow/teddy bear. Susie finds herself not minding. Just a little drabble set in my Hopes, Dreams, And DELTARUNE universe, sometime after the second book, though it can be read alone.

Zane dies to the overlord but his afterlife is not exactly the Departed Realm. He winds up in the Underground and quickly makes friends with most of our main characters. Of course, everyone's favorite TV personality finds himself falling hard for the new bot in town. Drama and Romance ensues, but no bloodshed. When Frisk Falls the Underground won't look the same.

(This is a work in progress. I own nothing. Sonic is owned by SEGA, and Undertale is a product of Toby Fox.) When a blue hedgehog that can go faster than the speed of sound and a small child fall into a mountain… they will find something quite unexpected… This is a version of the Pacifist Route with Sonic in it. I will upload infrequently. Review if you enjoy!

25 years after the pacifist route today was Firsk’s 25th birthday and Toriel was going to head to the grocery store but she never came back and Firsk was on her way to find her but what she stumble upon was a old wooden workshop that seemed abandoned for centuries...

What if Frisk went to the world of Fairy Tail?

When Eddy's scam fails again, the Eds and another kid must work together to escape (or save) the underground. Will they survive? Will they make friends? Read and find out. Ed, Edd, n Eddy by Danny Antonucci. Undertale by Toby Fox

Who knew dying could offer new possibilities to monsters? Or more like a second chance like humans have? Now, it sounds cool if only it wasn't for the fact that I have been transported to Hell... as a Human itself. And why is this other smiler so interested in me? Oh well, at least it's a beautiful day outside.

Omori had been repeating the same adventure for two whole years now. Some people might think Omori would hate how repetitive it all was, but they would be wrong. Omori loved the repetitive nature of his life since it made his job so much easier. So that’s why Omori was annoyed by the fact he fell down a mountain filled with monsters instead of going on his usual adventure

Richter's past few years were a living hell for him. So, when he got the chance to redeem himself by killing Shaft and Dracula for the second time, he gladly took it. Too bad a Belmont's life is an unlucky one. In the end, he found himself in a completely different world of monsters; one where they weren't constantly attacking him. Good for a dying man like himself, he guessed.

you were adopted by Nightmare Fredbear and his family. you were given chores that you have difficulty completing.

Sonic and his friends are teleported into an unknown area, separated from each other. There, they meet an unknown tribe of people called "Monsters" who are trapped in this place. When the Monsters find what they are looking for, however, the morales between them and the Sonic gang clash for what's right and wrong. (Rated T for some instances of swearing.)

With no memory of how he got there, Frisk has to work together with another kid to survive(and maybe save) the underground. But how can they do that if they can't reset and the other kid is less smarter (and way stronger) than them? (Prequel to Doki Eddy Literature Club)
