Summary
Reality and Fiction. One that resides in our world and the other that we create. Now, what if I tell you that there’s a universe where two exist in the same world? In a world where both real people and fictional characters live on the same planet, what do you think would happen? Would it be peace, chaos, or something much deeper? Let’s take a look at one of them to see how they live in such a world like this and find out for ourselves!
If you want to adapt this into a comic, animation, or whatever you want, then you can do it without my permission. Just don't forget to credit me as the original creator of the AU.

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:

Roman is your average college student. Overworked and underfucked. Too little sleep and too much caffeine.
However, she starts to find that her serious lack of sleep is leading to some crazy dreams.
Dreams in which she's now a skeleton, with three alternates, and a buncha other skeletons that seem hell-bent on trying to get her to understand that she's not in fact in a dream after all.
Will she ever believe them? And how much will it take her to get there?

Summary
Undernova AU: in which the remnants of stars live within monsters.
Over time, due to the frequent experience of negative emotions, the star transforms into a new stage — a "supernova". In this state, the host temporarily shifts into an enhanced, "buffed" version of themselves, which significantly increases the monster's stats.However, it's not all good. When the host's power runs out, they suffer prolonged, severe damage from the star "burning out" inside them, which can potentially be fatal.
Because of the fear of entering the "supernova" phase, some monsters became stingy with their emotions. Others, intoxicated by the unimaginable power, began to sow chaos.Her name was Altair. She was a skeleton monster — the last skeleton left after her father, Gaster, was consumed by the machine. Alta spent years trying to get that junk heap to work, but it remained silent.
Until today.

Summary
Sometimes life throws you a curveball. For you, your curveball was going to bed looking like a human, and waking up looking like a monster.
A skeleton monster to be precise.
With the barrier breaking, a large surge of magic descended on the town you live in, and transformed you overnight. Unsure what to do with you, and the others changed, you're ushered into a facility until a monster with similar magic can take you to teach you how to wield the now uncontrollable magic you've been given. After waiting in this place for four years, you'd given up hope that anyone would ever want to take you.
What a surprise for you when you find out that someone does. A lot of someones.

Summary
You only wanted a normal life.
Then you met them.
Sanses and Papyruses from different worlds, each carrying their own past, their own wounds, and their own ways of becoming part of your life.
For a while, it almost felt simple.
Then the timeline broke.
Now everything has started over. They don’t remember you. You don’t remember what you lost. And yet, somehow, the same familiar warmth keeps finding its way back.
Because some bonds do not disappear just because the world forgets them.
Arc 1: (Familiar Warmth) Chapter 1-18
Arc 2: (What Survived) Chapter 19-20
Arc 3: (True Beginning) Chapter 21-60 (Subject to Change)
