Summary
The moment Gaster set his eyes on you when you first appeared in that Core, it was love. Love at first sight.
He does all he can to see you again. To create a connection with you. To be with you. To have a life with you.
All those feelings.......and you don't even know he exists. You just bought Undertale and installed the game. Unaware that your moment of purchase and installation created a temporary appearance in the world of Undertale. Though W.D. Gaster was the only one present to see you at the time.
He thinks he was chosen to be your love. You were just interested in playing the new indie game that was released recently that you heard about online.
You don't know what your short presence did to Gaster. How you impacted the story, at least in the game you own.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The story starts with Undertale and continues on with the story of Deltarune, but it will be a while until then.

Too bad he reincarnated as a human in a world full of monsters (the literal kind) . He's not the hero. He's not special. He's just some guy… and somehow, that might be a problem.

Frisk has faced danger and death many more times than any child should ever have to, but they aren't out of the woods yet. Being the first human in who-knows-how-long able to use magic has shoved them back in the spotlight.

Summary
Two years after the events of the true pacifist ending the player did something incredibly risky. With Chara's assistance, they were successfully able to reestablish a connection with Frisk, but this had unexpected consequences. It caught the eye of a threat far more dangerous than anything Frisk, Chara, or the Player had ever seen before. It captured one of them, and gave the other two a choice, save their friend and convince them to change their mind, or watch as the entire universe is annihilated.

Author's Note:
This is a project that has been set up and decided by random rolls of the dice, as a dedicated hater of popularity contests where only the mainstream choices ever see the latter stages of a competition. Now, everyone had an equal chance at winning or losing, and no amount of audience participation will change it. Better hope your favorites won their rolls~
If you'll notice the Fandoms, you'll see that there's nothing except the Furry Fandom listed despite the massive cast present. Blame the tag limit. The characters themselves are more important to be listed than the fandoms anyway.

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.
