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.

Summary
Nightmare Sans is the most wanted criminal in the multiverse—a ruthless, cruel killer with an insatiable thirst for blood. That makes him the perfect prey for the parasite hunting him down, a being that won’t stop until Nightmare feels the same terror he inflicts on every soul in the multiverse.
But the parasite doesn’t count on someone managing to feel compassion in their soul for the guardian of nightmares.

Summary
The dichotomy between black and white is your constant when it's time for you to meet the whole new civilization Frisk brought along with them to the Surface.
As a parent, it's not easy to trust others when they've hurt your child.
So when that new civilization decides they owe Frisk both for saving their kind and for still hurting them during that process, you've got plenty to say to them.
Forgive as easily as you once did with others during a stage of naivety? Oh, hell no.
They better have a good reason for hurting your child and an even better one for wanting to be a part of their family.

Summary
Lyra, a devoted Undertale fan, decides to play god by rewriting the game's code to grant Asriel Dreemurr the happy ending he deserves. But when her actions pull her into the Underground itself, she finds herself trapped in the very world she tried to control.
!!!!This story contains graphic descriptions of violence, body horror, and themes of grief, trauma, suicide, and manipulation aaaand a lot more. While it may seem fluffy at first, darker themes emerge as the story progresses. There are still plenty of warm, comforting moments, but I don’t want to mislead anyone expecting a purely lighthearted tale!!!!
Also, this is very slowburn — Chara’s and the MC’s relationship progresses slower than you might expect. If you find yourself feeling frustrated with how I write Chara early on, please know it’s intentional and part of the slow build. Thanks for giving it a chance! <3

Summary
Tired of searching for a good Errorberry fic? Well look no further!
Blue has always had dreams of a darling skeleton whisking him into adventures and activities and waking up with burning cheeks or tears in his sockets. Blue sometimes dreams about a tree. Bright lights. Dying... But what if his dreams aren't, well, dreams?
Error has always struggled with his memories before the antivoid. How did he get there? Was he born, well, created there? He doesn't feel like he was. Error knows he had a life before destroying. His soul aches sometimes whenever he watches Sin and Toriel look at eachother all lovey-dovey. But when he meets Blue, his soul not only burns brighter than ever, it aches worse as well...
Will these two skeletons learn what's up with them? Or will they dance around this feeling of recognition and longing?

Waking up in an empty underground with no memories other then common sense: Check
Constantly seeing numbers all around you, not knowing how to get rid of them: Check
Looking Like a computer crash in real life: Check
Who the Hell did I piss of to get like this
[ Sorry I have no idea how to do summaries, But this is my take on Fatal Error, he is a lot more Out Of Character then compared to canon and he has a different backstory then his canon counter part.] -

Summary
The human was not gonna back down nor fight, and Sans, if possible, wanted to avoid a violent escalation of the situation as well. Because, despite the souls’ best efforts, his body had not yet recovered from his escape. Every single one of his bones ached, and he was almost certain that the cracks that already covered a majority of his skull had expanded.
However, the stalemate didn’t last long because, as it seemed, the human had an ace up their sleeve. The outline of a black soul manifested on their chest and, soon after, a bright red button with ‘RESET’ written on it appeared in front of them. Sans barely had the time to notice Killer’s eyes go wide and wonder why that was before the human pressed it.
Sans stumbled onto a snowy path with no grace, alone and lost in an unfamiliar frosted forest. Snowflakes slammed harshly against his bones. They looked so delicate and yet he could swear they left a thousand tiny cuts on him. It was torturous… and yet familiar.
That was the power of a human. No. That was the power of an anomaly.

Summary
He thought that the radiation would kill him. He thought that his time as the Doctor would come to sad and brutal end. He was wrong. And that was so much worse.
In his efforts to find himself, and without his companions, he accidentally stumbles onto a monstrous civilization miles below the Earth. With his newfound DETERMINATION and some new allies, he'll come to realize what it truly means to be a friend, and learn how to live his last lives with his head held high.
And make sure that, just this once, everybody lives.
OR
Undertale but the Tenth Doctor replaces Frisk. Fluff, angst, and time shenanigans ensue.
*No knowledge of Undertale or Doctor Who is required, though it is helpful if you've experienced at least one of them.

Summary
This is a human dom/subverse, but with my own version, so there will be differences. The main ship is Afterdeath, and the other ships included in this story are Errink, Cream, Crossmare, Kreme, Dustberry, Killermare, and ScienRed. This story is very NSFW and has a tiny bit of non-con and attempted suicide. There is some plot.
"Well, you seem to have been caught red-handed, " the man chimed, and Geno sighed. So the man could tell immediately?
"I'm not a sub." The dom raised an eyebrow.
"Really? That's the best you can come up with?"
"If you don't believe me, that's your own problem." He snapped back, looking the man in the eyes. The dom looked surprised before smirking and leaning forward.
"Did you know you were a sub?" The man commanded, not giving him even a second to resist, as it was so sudden.
"Yes, " he was forced to say. His eyes widened as he cursed under his breath. The dom's dark eyes bore into him with amusement, making him want to shudder. He had never been forced by a command before.

Summary
Momento Mori- Latin for 'remember, you must die'
What is death, if not the end of one chapter, and the start of the next. Raine is dead. She wanted to be dead. She made her bed. Cleaned her room. Said her goodbyes. And tied the noose. When that didn't work, she slit her wrists. And when that didn't work, she took her grandfather's gun off the wall and shot herself in the head. That time, she finally did something right. Now she could sleep peacefully....
Why was she awake? She was definitely dead this time, why the hell was she awake?! And is that......Sans?! As in, Sans from Undertale?! As in the game that was one of her only reasons for not killing herself in high school?! That Undertale? That Sans? Why was he multiplying? And is that Papyrus?!
Death hurts. It causes pain to those around it even when it isn't attacking them. Then it comes for them next. If she wanted to get out of the Undertale world and back to her hopefully peaceful afterlife, she would need to show some bitches that before they bled out their marrow..... all over her damn floors?! Dammit Mutt, she just cleaned those!

Summary
Blue moves in with a mysterious roommate after heading to Ebbott City to pursue his passion as a pastry chef. While Stretch isn't a huge fan of his brother moving in with a stranger, it's quickly clear that Dream poses no threat whatsoever. Even though Dream is perfectly safe to be around, there are other things on Blue's mind when it comes to his roommate... perhaps some not so pure thoughts, which may or may not be reciprocated.

Summary
This is the final part to the Kingdomtale pacifist series. I have a few other works I wanna post as well that are also kingdomtale related so keep an eye out for those. Also if you haven’t read parts 1 or 2, go read them! They’re gonna help explain how we got to this point in time.
Warning: may contain mentions of abuse, violence, death, dust, blood, depression, attempted suicide, cursing, romance, weird/Toby logic and ships. If any of these bother you then why are you still here? Otherwise, if you are fine with these things please enjoy reading this grand finale! This takes place after part 1, humanity’s creed, and part 2 of this series. Our protagonist Frisk is only referred to as a girl or she/her when it’s the humans talking due to the time setting and because of the morals discussed in humanity’s creed. Otherwise they are referred to as they/them (nonbinary pronouns. Or whatever other nicknames I mentioned in parts 1 and part 2). All oc’s are owned by me, other characters are owned by Toby Fox.
