How Do You Kill a Time Traveler by ZJFoster (toxicnuts69)
Fandoms: Undertale (Video Game)
15 Jun 2025
Tags
Summary
let me describe to you a hypothetical situation. you are a time traveler. you work in the business of space and time and whatever distortion that may be caused by any such anomaly. timelines jumping left and right and the space-time continuum would be bursting at the seams if this loop wasn’t trapped in its own bubble, making your job of discerning who being positioned where in time in space irrelevant and admittedly— a lot easier. your job is to do whatever it takes and whatever you can to shut this down, even at the risk of your own life. you just wish he wasn’t here with you. even though he needed to be. couldn’t he have taken the day off? you can’t help but wonder how many times you’ve stepped out that door.

Summary
Something has been happening to the multiverse lately. Portals have been opening up around places. Now that's a pretty common occurrence. Sometimes it just happens. However, the amount of portals that have been opening up are becoming more common than usual. Unfortunately, one AU!Chara stumbles into a portal and gets trapped in the multiverse, realizing the potential scale of their world. Fortunately, at least a multiversal god cares about these problems.
Becoming enlisted in the Omega Timeline Scouts, they put their work and effort to find out the reasons as to why the portals and errors have been popping up around places. Being put in different AUs, Chara, Storyshift Asriel, and Frisk hope to bring back how the AUs were before this sudden shift. Chara also wishes to return back home to their loved ones.
(Will probably update this summary a bit more later on! Also they join in chapter 4 (or realistically chapter 3 considering the first one is a prologue))

Summary
There's been an epidemic of monsters suddenly falling unconscious, never to wake up. It's been labeled as falling down and the patients the fallen. As the Royal Scientist, Alphys has been put in charge of fixing things. But what is she supposed to do when her girlfriend's mom is among the fallen? Or when she makes things so much worse? How can she face Undyne or tell her what she's done? How will she fix this?
Might be a little out of character because I haven't played true pacifist in a while and I'm at the Sans fight so I don't want to reset to start true pacifist

Summary
The year is 202X. The deaths of Chara and Asriel are fresh on Monsterkind's mind, and the environment of the underground is harsher than it will ever be.
Enter the Patience soul, Eleanor. Thrown into a world she is not prepared to exist in, she must desperately struggle to survive in a world hellbent on killing her.
This is my take on the concept of "Undertale Cyan", a story centred around the first of the six human souls to fall into the underground.

Meanwhile, a flower, opposed to both the Guard and Clover's friends, secretly tries to do his best to make sure the next human faces Asgore with as few hitches as possible in case he can't absorb their SOUL first. He doesn't feel the need to try too much. After all, if his plans fail, he can always reset... right?Series

Summary
As the Royal Scientist of the Underground, Doctor Gaster was used to being given various tasks by the king of the monsters, Asgore. The first of them since they had all been sealed underground after the war was to help monsters settle down into their new home. And the second of them had been to establish a more consistent power source for monster-kind. Of course, the Steamworks had originally been developed to do the same thing, but the power it provided wasn’t nearly enough to cover all of it.
Over the course of several years, the Royal Scientist had designed the CORE and had it built, a much larger version of the Steamworks that managed to successfully run power through the entire underground. And it wasn’t even like his position had only been granted to him after being sealed underground, he’d been working for the king and queen for what must’ve been at least a century. Pros of being a monster who’s yet to have children, he supposed.

Summary
“........I’m sorry, my friend.”
“i’m sorry, my friend, who?”
A sigh filtered through the door. Sans almost imagined he could feel the breeze of it.
“I’m sorry, my friend who has been so kind as to attempt to cheer an old lady who is currently beyond cheering. I should have known better than to visit today.”

Summary
A few years after everything is over with Vecna, Steve and Robin decide to take a vacation to live life a little. They end up back in another convoluted scenario that only their luck could bring upon them.
They've fallen into another world where monsters lived (which, this wasn’t even the first time!). Now, they've got to either figure out a way out or settle into life in this new place, all while dealing with a mystery involving their souls.
Steve blinked, and the whole world changed. Everything seemed grayer, suddenly, and there was a single heart floating in front of him and Robin.
The flower’s face dropped. “What the fuck? I swear I pulled both of you into the encounter.”
“What does that even mean?” Steve asked incredulously, bat quickly back to being raised in front of them.

Summary
Day 9: Found Family
An old turtle monster with graying hair settled onto the ground by a low table. He’d pushed the cushioned seats off to the side, finding comfort in the familiar hard stone. He reached forward to grab his teacup, still warm, and breathed a small sigh of relief at the serene silence. The only sound was his breathing and the peaceful waterfalls outside his home.
Thunk, thunk, thunk.
Ah, never mind then.
He smiled wide as he sipped tea and closed his good eye. His home’s door was slammed open, the force knocking much of his cluttered items down. He didn’t bother to see who it was. He already knew.
“Gerson!” She called.
He peeled his eye open and lowered the tea.
He laughed, “Hello, sea urchin!”
. . .
She remained in the open door, pointing at him with a familiar fire in her eyes.
She demanded, “Have you ever heard of Gyftmas?!”Series
