    Summary

    Summary

    Gaster made a plan. It was a stupid plan with little thought put into it and what started out as something that was only meant to keep him occupied over the course of a few months; became a lifelong commitment and he's not sure if he's okay with that.

    After slicing a whole in his hand and impregnating himself with the altered DNA; doctor Gaster thought that this would be a fun way to study his colleagues behaviors; but he failed to think about what he was going to do when the subject was actually born.

    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.

    (Title was formerly “Forbidden Memory”)

    They cannot completely suppress his memory. He was too much to too many to be completely forgotten.

    He was a brilliant scientist, a loyal friend, a loving father.

    Summary

    Reader leaves home to chill down a little and she falls into the Underground. Sans is there, ready to meet the anomaly of the timeline, but he feels like his soul is calling for her. He knows there's something wrong. Where is Frisk? Why is (Y/N) there instead? Why did she fall so late? Why can't he get the fog out of his skull and remember?
    He needs someone he can cling to. But he can't let himself. Not yet. You'll help him and the entire Underground lead to a fair life on the surface. You'll make sure of it. And you'll lend Sans your shoulder. You'll slowly convince him he can lean on you, past his shell.
    The only problem is... what is he hiding from you?

    Summary

    War is raging, but not the one you might be thinking of. Monsters and humans set their differences aside to fight together against the beasts that rised from the deepest of the ocean. Jaegers are being put back together from the dumps in one last desperate attempt to turn the tides before it's too late.

    One salvaged jaeger is ready to be deployed. Few candidates are deemed good enough to be potential pilots, and even fewer are potentially compatible.

    To everyone's astonishment, the one with the final say on the matter is this strange newcomer, who's all but predictable. He claims to be a pilot. Only time would tell.

    (No need to know Pacific Rim lore other than the first three minute sequence of the movie and maybe a wikipedia summary to follow the story. Still, the movie is awesome, watch it anyway)

    Summary

    Skeleton monsters aren’t designed to swim.
    It was this thought that passed repeatedly through Sans’ head as he clung to the tiny sailboat he had taken far out to sea, now in the midst of a hurricane level storm. In hindsight, this had been a very bad idea.

    Summary

    [Y/N] [L/N] is a powerful mage with a bloodline well-known throughout the ages and her family have always been celebrated. They, however, despise how their bloodline trapped monsters beneath the ground. But, that is for another day. In not being able to afford basic accommodation for university, they had to rely on an old (and terrible) friend named Bethany. For some reason, most of Bethany's skeleton mates despise [Y/N] but why is that? Apart from the fact she is a mage?
    Just because she has a kindness soul, it doesn't mean she will stand for their bullshit.

    Summary

    Part of Tsunami events. No need to read it first but it’s heavily referenced.

    Just mindless grillster fluff that doesn’t really fit in the main fic. Basically snippets in vague chronological order that kinda resemble a plot maybe. This takes place at some point after chapter 29, parallel to the story.

    Enjoy ye filthy shippers.

    Summary

    It's... Not really what you had in mind?

    One moment, you were having a nice picnic with your family—and in the next you're forced into an Encounter and the Monster King's guards kidnap you.

    ...So yeah, definitely not the Sunday you were expecting, but...

    It could be worse, you suppose.

    You could have been kidnapped just for the sole purpose of being forced into a marriage with both of the King's sons.

    ...

    . . .

     

    ...Oh wait.

    Summary

    A clack, a clatter, as something fell to the ground. He jolted back into awareness, his whole body aching in pain as the dust settled. The… the experiment… it…

    He hissed in surprise as he tried to move, his arms and hands flaring up in pain the moment he so much as twitched. He could barely feel anything past the pain, and the worst of it was concentrated on his hands. Just what happened

    Summary

    There were many types of creatures in this world.

    Human, Mages, Monsters, Mer and Sirens.

    I am a Drowned, but I was a Monster.

    We are the unheard, the unseen.

    No-one talks about us, when we are turned we no longer exist.

    Well, I refuse to go silently! I will survive and I will get home! Wherever that 'home' maybe.
