Summary
Disoriented and emotionally frayed from decades spent in the void, W.D Gaster suddenly finds himself at the mercy of a cold and arrogant alternate self. His doppelganger promises to return him to the void once his research is complete but before he can make good on his threat, Gaster is introduced to this world’s variant of his son and he is forced to make a quick, spur of the moment decision.
This sole act sends unforeseen ripples throughout the Multiverse and hurdles Gaster on a perilous journey across it to find his way home.
or
Dadster plays hopscotch across the multiverse, unintentionally and intentionally acquires children, tentatively reciprocates Grillby's feelings, engages in actual literal custody battles with copies of himself, somehow steals a Bad Sans™, narrowly avoids death at the hands of Error and somehow flies under Ink’s radar for a shocking amount of time.

Summary
Fall cleaning was Gaster’s least favorite time of year. Don’t get them wrong, they absolutely loved fall, from the holidays and decorations to the various seasonal treats, it was by far their favorite time of year.
Except this. See, it wasn’t the cleaning itself that was the issue, she actually rather loved cleaning, but rather a specific stack of boxes in the back of the attic she always managed to stumble upon. It didn't matter where they were trying to go, what they were getting, or even where they were facing, it was always there. It seemed to haunt her, always sitting in the back of her mind. It wasn’t even like there was something awful in those boxes. They were actually incredible things. Things most people could only dream of obtaining, things that would make anyone else feel like they were on top of the world.
Anyone but her.- Language:

Summary
Maybe, on second thought, this hadn’t been one of Gaster’s brighter moments. It certainly didn’t rank among his most idiotic moments yet either, but still. Perhaps not the best idea.

Summary
"El odio es un sentimiento... interesante. Puede hacer que te cuelgues de el, cegarte por la dulce tentación de vacilar y envolverte en el, de dejarlo meterse profundamente en su cabeza, convencerte de hacer cosas horribles, de convertirte en una criatura horrible. Pero... el odio tambien puede impulsarte, ayudarte a encuentrar los modos y establecer los lineamientos para cumplir lo que te propones, incluso de cara a un panorama complicado o de pocas oportunidades. Es una emoción divertida, ¿No crees?"
Solo una interpretación diferente de como podría haber sido si Sans hubiera obtenido determinación a través de su odio por el nuevo dueño de la línea de tiempo, Frisk.

Summary
Год. Столько длится контракт Гастера с Академией. На год он уедет из Сноудина, чтобы заниматься разработкой «Ядра». Всего лишь на один год. Это меньше, чем Гриллби служил в армии; это меньше, чем он участвовал в войне. Такой короткий срок. Между ними ничего не изменится за это время. Так ведь?
Year. That's how long Gaster's contract with the Academy lasts. He will leave Snowdin for a year to develop the "Core". Just for one year. That's less than Grillby served in the army; that's less than he fought in the war. Such a short time. Nothing will change between them during this, isn't it?

Summary
Gilbert-- nicknamed "Grillby" by his best friends in college-- deals with the aftermath of those friends suddenly disappearing and having to attend their funerals. But they aren't dead. They can't be. It just doesn't make sense. He recruits the help of some other people who knew Gaster to find out what happened. Takes place in the DDAU. Follows the other side of things from "Wind and Fire" (hence the title)

EDIT: 10/6/25: For the anniversary of my first ever completed fic, I went through to fix the formatting and do some editing. Accidentally added 2k+ words. Happy anniversary

Summary
Living peacefully for centuries, monsterkind has flourished on the lands that were fought over all those ages ago. As technology starts to spread due to the success of the CORE, a rumor surfaces of a dragon laying waste to the furthest reaches of their kingdom. A rumor, which Gaster believes is just his old friend trying to get him out of the Capitol and add some excitement back into his life.
Well, it'll be something to do, so, Gaster accepts, and along the way picks up a friend, a fire elemental - a monster that Gaster was certain had been forgotten to time. Now with two mysteries to unravel, the two travel together to learn if the dragon is real, and about their paths in life.

Summary
From the earliest time he could remember things… things clouding his early years of life. Maybe it was sadness…. or loneliness….. but even as he felt his skull hit the pillow, for once he felt relief. And the skeleton was now enjoying his life.
“But wait… this isn’t quite the beginning isn’t it? See I never quite explained who HE is, did I? Let’s start from the beginning shall we…. Uhh hold on-“ *shuffles paper* “aha! First things first… this is the story of (insert Tale name) or more specifically uhh the story of someone… well of something written by- oh you guys! Well the story starts..”

Summary
Extras for Two Deaths that don't work as their own little ficlets. Alternative POVs, discarded scenes, that sort of stuff. This will probably not make any goddamn sense if you haven't read it first, but if you want to read this anyways, more power to you. Same as the fic, will center Gaster & Grillby, sometimes both of them.
First chapter is an index with short little summaries. Each chapter's warnings and ratings will also live in the chapter's beginning note.

[podfic] (original work)
They've been Underground for a long time, enough for numerous inventions to be created for a better way of life for all the monsters trapped here, and all the monsters who have come to known only the caves as their home. This one however, is probably the best Gaster's ever made and he can't wait for Grillby to try them on.
