Summary
Twin Runes es un AU cómico en su mayoritariamente alegre centrado en los universos Deltarune y Undertale. Una fuerza desconocida ha provocado que aparezca un punto de conexión entre los dos universos, lo que hace que Frisk y la molestia fantasmal Chara tropiecen en la vida de Kris en uno de sus muchos reinicios (para gran disgusto de Kris). Se produce un caos que rompe el juego.
La traducciones del "los pájaros y abejas" hasta el "No sirve pa' nada" no son mías. Del resto de traducciones si son de mi autoría

Summary
The world is different. It seems smoother for whatever reason.
You throw the blanket off yourself, shakily standing up.
Weirdly, it's night. Even more weirdly it's not Toriel who woke you up. Is it not the new Game?
* (oh &;@#@... where am I?...)
You sharply turn around, staring at the red pulsing soul hovering above your bed.
✧ Encountered the Player!
You engage red soul in a battle!
The soul hasn't noticed you yet.
It seems like they're disoriented.
A faint melody on piano plays in the distance.
It's slow. Big pauses as if someone forgot what should go next.* Or: crack mixed into serious narrative where Player is a menace, Kris is a dumbass who has no idea how to live with their own autonomy and canonical angst is forgotten in favour of fanfictional angst
* Or: Kris gets to start a New Game for themselves and Player loses most of the control over them. Unfortunately, they have not a single idea what to do about it. They'll try to do something anyway.

The dad who stepped up and put on a show (Tenna Dreemurr AU) by Suspicious_Cat

Summary
So, I know this AU has its own storyline and events that happen, but I wanted to like- make an AU of that AU? A spin-off of the spin-off, if you will. :]
(The au called 'Tenna Dreemur' by 'MimiZukeii' on Twiiter/X, that is. Yes they misspelled it, that isnt my mistake.)It's just what I imagine could happen with Tenna in such a strange situation, and I do love myself some 'found family' (if you can class it as that.)
So, read this if you want to see some Tenna struggling to be a single dad of a crazed monster and a fluffy boi.

Summary
When Chara Dreemurr lay dying in the Hall of Judgement, all she could think about was seeing Rei again, wrapping her arms around her fluffy brother, and telling him just how sorry she was that she couldn't protect him, that she couldn't protect them all, from her twisted reflection.
What she didn't expect after her eyes shut was for them to open again in an unfamiliar room inside something called a hospital with her wounds cleaned and tended to before being taken into the care of a doppelganger of her mother and what seemed to be a second reflection, named Kris.
What she expected even less was to find herself part of a prophecy that foretold the world's destruction and how it would be saved by Four Heroes: two humans, one a noble warrior, strange and mischievous yet just and brave, the other, a devilish rogue from parts known yet unknown, a monster, brash and bold, and a lonely prince from the dark.
But, what Chara didn't expect least of all, was her and Kris growing closer over the course of their adventures... and coming to see each other not as reflections in some unseen mirror, but as something more, something deeper, something intimate.
Their other half.

Summary
Kris is not one to converse much...
Kris is usually the type to keep to themselves...
More often than not, Kris seems to be a loner...
The one destined to be alone, while everyone else enjoys each other's company...
And yet... Kris is always the one people confide in.
Their troubles, their doubts, how weird they can be, even their deepest feelings.
For better or worse Kris is always there, and with these interactions, changes occur, and new revelations unravel. Both for Kris, and those they've formed connections with.A collection of short stories featuring Kris, and the many individuals they've met old and new, delving into their relationships.
Newfound dynamics come about because of their interactions, and Kris comes to learn they have much more of an impact on the individuals they've met, and appreciated for who they are, even if they don't think so.
