Summary
"What happens when a mastermind strategist is trapped in the body of a twelve-year-old girl?"
Nick is a genius, a tactician, and a pathological liar. After a chaotic soul fusion with Chara, he finds himself in a body he didn’t choose, living a life he didn’t ask for. While the Dreemurr family sees a child who needs protection, Nick is busy playing a high-stakes game of chess against destiny itself.
He’s not here to be a hero. He’s here to regain control. Whether it’s bluffing his way through scientific debates with W.D. Gaster or struggling with a body that betrays him at every turn, Nick will do whatever it takes to survive.
Anti-ControlTale: A story of identity, 22nd-century tech bluffs, and the brutal reality of being a man stuck in a vessel that isn't his own.

Summary
An scientist. Or what you called yourself, a mad scientist? You probably just wanted to sound cool. So much to the point of every other borrower wanted to explicitly kick you out of the pack. The only reason for your own mind hasn’t done such was because you were currently working on a medicine to help the sick borrowers.
But time was getting cut short.

Summary
You’re just trying to live peacefully after everything you’ve been through. But peace isn’t easy when you suddenly end up in a town full of Devils.
Rias Gremory and her peerage don’t know what to make of you—the human with impossible determination and a smile that hides a thousand scars. You don’t like violence. You don’t want to hurt anyone. But danger keeps finding you anyway.
So you do what you always do.
You refuse to give up on anyone.
Even if they’re a Devil.
Even if they’re a Fallen Angel.
Even if they’re you.
Even in a world drenched in sin and desire, your choices still matter.
And this time, they might change Heaven and Hell alike.

Summary
Well.
This was new.
Chara was not accustomed to being see-through. After all, being corporeal had been their natural state for most, if not all of their life.
Did that make this non-life or undeath?
They were doubly unaccustomed to seeing another human in the Underground.
Were they dressed as a cowboy????
------------
Basically: Undertale Yellow if NarraChara was still prevalent! What will change? What will stay the same? And WHY is this flower following them around so intently?!Note: This is not connected to a (possible) DND project, it's just connected via being Cocoapowder related.

Summary
A series of dialogue. A set of numbers.
After a slew of countless RESETs, Flowey is driven out of sheer desperation to commit a taboo he has never tried before.
While Papyrus vows to try to help and understand his friend…the truth comes to light when Flowey expresses that he will never feel the same way any other monster can.
Flowey comes up with his own solution for this, and it's not a pleasant one. But apparently that's okay since consequences are usually beyond Flowey.
…But now things are suddenly escalating beyond his control. Not that Papyrus ever had any control to begin with.
Flowey, the Human…is who is in control really the point?
…So then…what's left?
Only the Pretty Poppy can decide now.

Summary
Life isn’t fair, case in point, you didn’t expect to be trudging through the snow to the corner store to pick up some much needed, over priced, feminine hygiene products while trying not to bleed all over yourself all because you failed to remember to pick them up with your normal shopping. That’s the thing, no one ever said life was meant to be fair did they?
~*~
Promises were just words, promises of home, safety, love. Only ever worth something if the person kept those words close to their soul. That was something he learned pretty damn quick. Built for love, to be a friend, a companion, tossed into the rings to be a fighter, something he was never meant to be. The only promise he knew he could trust were the few he made to himself, the promise to never fall for the sweet lies of a pretty face again.
~*~
What happens when two souls who honestly need each other, don’t know how to open up and trust? Can love, trust, and home be found when the world has proven that trust is a dangerous thing? Can they get over the hurt that this unfair world has piled on them? Open up to each other and maybe, just maybe find the home they both need?Series

Summary
The strong nuclear force is defined as the strongest of the four fundamental forces of nature. It is the force that binds protons to neutrons inside of an atomic nucleus. On the quantum level, it also binds quarks of similar charge and direction together in order to form protons and neutrons.
The summer after her graduation from undergrad with dual degrees in biotechnology and theoretical physics, the world around Vera Jefferson changed. An entire new race of people poured out of Mt. Ebott, the namesake for her university. The monsters that now populated the militarized zone around the campus and base of the mountain were strange, but kind. Having made quick friends with the sarcastic bartender/owner of the restaurant across the back alley from her apartment, it seemed as though her world had changed for the better.
Once she starts the first semester of her PhD, she realizes just how true that is when she meets some of the other monsters around campus. Life may not be easy, but with the help of the people she went through undergrad with and her new friends from underground, she feels for the first time that she just might make it through.

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.
