Summary
In search of a missing relative near Mt. Ebott, Frisk falls in the Underground. What should have been a short stay soon turns into a perilous journey through places far different from what they expected.
Note: This story is my personal interpretation of Storyshift. It includes some heavy headcanons that diverge from both the Pre-Boot and Reboot versions of Storyshift. I am using this AU as a creative sandbox, so please keep that in mind while reading!
Check out the original by Voltra here:

Summary
After Frisk has broken the barrier, Chara says their goodbyes and moves on. Frisk tried to live their life in the surface, being with their newfound family, but the thought of Chara still persist in their mind. Unsatisfied with how Chara's story ended, Frisk goes back to Mt. Ebbot and starts a new run. Frisk will find a way to give Chara a better ending, no matter how many resets and runs they have to do. Even if it means breaking the timeline, and causing the six previous human children to fall at the same time and present as Frisk.

Friendship and romance was the last thing on your mind. But the longer you spend time with the skeletons, the deeper you get entangled in their lives. (Also, welcome back Papyrus!)Series

Summary
The story officially begins when Toriel dies in her universe mysteriously. Gaster with his allies show up and take her soul remains back to his lab to save her life. Toriel then had DETERMINATION injected into her. Most of the DETERMINATION was collected from humans in multiple different universes. Gaster created the perfect solution to end RESETs and genocide routes that plague The Multiverse. A new kind of boss monster with the ability to utilize the power of the savestar. Toriel, who got reborn as Gaster's daughter in his lab due to a serious situation that happened, it was the only way to save her life.
Gaster embarks on his quest to bring peace and balance to The Multiverse. However The Savestar becomes corrupt, doing more than its intended function.
If the RESET function is over-worked, it will erase a universe. The more universes that are gone, the more The Multiverse dies. They explore every universe they're able to, attempting to fix the savestar and rid the ability to RESET, helping others and themselves.
Note: The AU is heavily in progress, unsure when new content will be published. Hope you enjoy what exists right now though.

Summary
"K-Kris... I... know this sounds crazy, but is there a chance we can... switch partners?" Noelle requested shyly, her cheeks reddening. "Like... I can work with Susie, and... you can work with Berdly?"
Kris didn't know why she was requesting this of them, or why she wanted to work with someone like Susie in the first place. But nonetheless, they nodded; as they didn't need Susie pinning them to a locker again.
The deer's eyes lit up. "Great! We can ask Ms. Alphys right now if you want!"
They really didn't want to work with someone annoying like Berdly, but... whatever.
or
Kris and Noelle switch partners for the project, and two unexpected romances blossom from there.

Summary
Echo did NOT break up with his NOT boyfriend, but he's still not okay. Meh, he doesn't really get to have nice things anyway. Not like it’s a big deal, he’s completely fine!
This fic contains: Mentions of self harm, manipulation, mild gaslighting(?), some very mild religious undertones maybe, desperation, depression and a LOT of weird talking flowers. Like Srsly they wont shut up. And dub-con mature content in the first chapter. No actual explicit smut tho. I think. I hope. This list may be changed or added to. Stay safe and read at your own risk.
Should update every Wednesday if I can help it (read: if I don’t forget) until I run out of complete chapters

Minha Cara Metade | Krusie by Echoptus

Summary
Kris e Susie sempre tiveram um conexão forte, talvez até meio tóxica antes de se tornarem amigos. Mas ao longo do tempo, quando mais mistérios e dúvidas inexplicáveis surgiam sobre os Darkworlds e sentimentos, esse vínculo passa a tornar-se mais forte...
Mas vários obstáculos se fazem presentes nessa jornada de "amizade".
Conseguirão superar esses conflitos emocionais e físicos?Essa história é inspirada na fanfic do ship Krusie "Algo dentro de mim" ou um título parecido, que aparentemente foi removida daqui. Infelizmente não consegui marcar o @ do(a) autor(a), mas gostei de certa parte do rumo da história e decidi dar continuidade.
Se passa no final do capítulo quatro e pode ter acontecimentos, fatos e personagens não canônicos.Os personagens e cenários citados são todos da autoria de Toby Fox.
