You couldn't believe what was happening. The Reset messed up and this wasn't home. This was a hellish version of the Underground where all of the monsters try to kill you. Above all else, something from another universe was after you? All you wanted was a happy ending, but nothing stays perfect, does it?

(This is a remake with a better plot, better grammar, more characters, and more story! I hope you like it! Original is on Quotev.)

Crossing the Limit (Undertale) by Espeon804

(Alternate Ending added!) "If you solve your problems with kindness instead of violence, then everyone wins! Violence isn't necessary! It only hurts people! It can sometimes make the conflict worse!" ----------------------------------------------------------------- He's kind. He's gentle. He is so forgiving. He always welcomed a stranger with open arms. He wouldn't hurt a fly. It's disgusting. But that is why Papyrus never fails to catch Flowey's interest. So, Flowey decides to cross a line. A line that is the border between forgiveness and retaliation. Rated T for violence and some language.

Chainsmoker [ Gaster!Sans x Reader ] by morrow-

Routine. The entirety of every living thing is dominated by it, human or monster. Everything HAS to be the same. It was in this that you were the exception. For you everything was new, every time line a detailed altered in order to satisfy your sadistic desire for a new ending, whether it be only a few details of dialogue altered or something else entirely. Monsters you once considered family you now butcher and slaughter without a second thought, after all, that's what the Reset is there for, right? And all at once it stops. Your small hold over the Underground is ripped away from you and you are thrown into a dying timeline, monsterkind's final attempt at self-preservation. You're alone, completely and utterly alone. Except one. And he has a bone to pick with you.

Oh Yes! Remastered (Mettaton X Male Reader) by TheGothicPrince

Undertale X Reader [In Remake] by Cat_Maipie

Let's get to the point shall we? So let's look at the list here... You're a... no information? Hm, interesting i guess, I'll have to base it off my observation. Whatever, you're a human, well kind of. You're a human and a monster at the same time, more like in between. Let's say... player? Better than nothing i guess. You're your own person. Sometimes you control frisk, sometimes you don't. You can also move through timelines, and also universes but that may be too risky huh? You'll find more about it soon... THIS CONTAINS VIOLENCE PLEASE BE WARNED! Lemons? Maybe. - #57 in sans 12/14/25 - #1 in floweyxreader 01/10/25 *** COVER : Credits to the person who made it GAME : Toby Fox

To Hell and Back (Gaster x Reader) by xsfolia

"What's that look for? Are you perhaps unhappy to see me?" "Oh no. Oh no, quite the contrary, my love. I've craved to be with you for the longest time" ***** You were sure that you would have captured a Monster, at all costs. But were you sure that you would have captured not a Monster's body, but a Monster's heart? ***** The Barrier is broken • Frisk has saved the Monsters • But not all things went according to plan . . . . ...... It is renowned that Frisk fell into the Underground. They spared everyone, they had [Mercy] for everyone. In the end, they have chosen to be an ambassador for monsters, to represent them in front of all the other humans. Frisk was full of [Mercy]. But the humans weren't as merciful as them. Humans completely forgot about Monsters, and now they had to deal with what they considered an ancient enemy, despite the Monsters' friendly intentions. What will Monsters do, if they suddenly are persecuted by Humans? Will they seek help? Will they search for old friends? ... Was it reality? Or was it a true living Hell? Things always went according to plan, so why? This time, why did it have to end like this? You are a spy, working for the most powerful secret Organisation of the Human Government. Your job is to find your targets and bring them back at the Organisation, but if you have the order to, then you have to kill them. This time however...you underestimated the enemy. ***** The new plan was quite simple: bringing him back in exchange for your freedom. Falling in love with him was not part of the deal though. ********* Word count: 110.473 Cover by Earth Garden on tumblr!!

Insanity by SatanTM

¥warning, this is a sequel! The first one is called Secrets.¥ After three years of finally having peace between monsters and humans something goes wrong. Frisk goes to bed and when she wakes up she's on a familiar bed of golden flowers. A scared and tattered little flower with a face befriends her and everyone else she knows is trying to kill her. It's like someone Reset and when they did everyone went insane. How is she going to deal with the love of her life and her best friends trying to kill her at every chance they get? How is she going to get back to her timeline with the ones she loves? And most importantly, who did it?

Soulbound || Sans x Reader by StrawberryMilkSnake

When a situation with a dying human ends up with you absorbing their soul, you panic (like any unprepared monster would). Suddenly Undyne is hunting you down, so you rope the mysterious skeleton next door into helping you. Which he does--in a very Sans way. And who knows? Maybe pretending to be his girl will pay off. | - Classic Sans x Monster Reader - Fake dating turns into real dating - One (1) very mysterious skeleton & one (1) very awkward reader - Papyrus is so sweet and innocent, I love him - Monsters really are in the wrong for killing children tho - I love happy endings and hate tension so expect an easy, relaxing read
