    Summary

    “Papyrus.”

    The voice that stopped him wasn’t sharp, or cold. Just quiet.

    Papyrus turned, startled.

    Gaster stood slowly. His arms were stiff at his sides. He didn’t reach out right away. He looked like he might be fighting something. Internally. Externally.

    “Come here,” he said.

    Summary

    “They’re trying, you know. Sans. Papyrus. E-Even after everything. They’re t-trying to m-move forward.”

    “I know,” Gaster murmured. “I’m not stopping them.”

    “You’re not h-helping them, either.”

    Summary

    “You made children, Gaster.”

    “No,” he says. “I made prototypes.”

    Asgore’s breath catches. “Prototypes.”

    Gaster meets his eyes. “They were never meant to grow minds of their own. They were never meant to be people.”

    Summary

    Sans groaned. “you’re embarrassing.”

    “I’M ENCOURAGING GROWTH.”

    “you’re loud.”

    “I’M INVESTED IN OUR HEALING JOURNEY, SANS.”

    Gaster coughed again. Not from tea this time.

    Summary

    Sans stared at him. Didn’t blink.

    “You sure?” he asked, voice low. “’cause you’ve been pretty good at pretending you care about your test subjects when it gets you results.”

    The room went colder.

    Gaster’s expression didn’t change. But his hands were shaking — just slightly, almost imperceptibly.

    Summary

    If Sans was really awake while his dad carried him to bed, savoring the feeling of being held like he had when he was younger, Gaster would never know.

    And if Gaster dreamt of tests, drills, and the sound of his two favorite kids in the underground screaming for help while he hurt them…

    Well, the boys never had to know.

     

    AKA a few nightmares send Gaster spiraling, and a failed experiment lands him in a new universe completely.

    Summary

    Asgore was the best father Gaster had ever known. He was endlessly kind, and affectionate, and patient. He was everything that Gaster knew he couldn't be. He needed Asgore, and more importantly, in this moment, these babies needed Asgore.

    Zarla-s's Mercyplates AU of their own Handplates AU where Gaster chooses Mercy and ends the experiment when Sans and Papyrus are just babies.

    Summary

    In one world, Gaster reaches into the Void, and the creature of his future(present)(past) comes through. In another, nothing comes out, but his experiments fall in.

    Now 1-S and 2-P Sans and Papyrus wake up in a brand new world: one where they have a happy home, two fuzzy caretakers, and a father instead of a torturer—and memories of suffering that no one else remembers.

    (Or: Gaster had many chances to make a better choice. In another world, he made those choices a lot earlier.)

    Based on the mixed Mercyplates/Momplates version of Zarla's Handplates AU.

    Summary

    Papyrus wants his daughter to get to know her grandpa. He also kind of sort of really doesn’t.

    (Handplates AU, Mercyplates variant, several years post-Pacifist ending. Papyrus knows he wants to be a mom. He just doesn’t expect how complicated his dad will make it.)

    Summary

    He wouldn't be able to keep this up, would he?

    He'd thought that he was determined enough. That he had killed off any sympathy that might have started growing in his soul for these two creatures, but the damn near permanent loss of Subject 1 had proven him wrong once again.

    There would be a lot for him to think about tonight.

     

    (My take on a merciful route set in the Handplates-verse by the amazing zarla-s (https://zarla-s.tumblr.com/) It's not very original, but I had a mighty desire to write it so here it is)

    Summary

    Gaster had the means to repair one of his greatest mistakes, but he never had the chance.

    Until he does. Now it's just a matter of whether he has the will to, and whether the one he has so horribly wronged is willing to let him try.

    Based on the "mercyplates" AU of Zarla's "Handplates." Sequel to "Bandages."

    Summary

    You always have a choice. You can always choose Mercy, no matter how many times you have chosen to Fight. You can always change your mind, become a better person, if you just try. But your actions have consequences, and no amount of Mercy can change what has already been done.

    Gaster chooses Mercy. He just does it a little too late.

    Based on Zarla’s “Handplates.”

    Summary

    Inspired by the comic Handplates by zarla-s.tumblr.com, this is my take on what would happen if a timeline where Gaster chose Mercy and a timeline where Gaster chose Fight intersected. This is set when they are arguing over Papyrus healing Gaster.

    THIS CONTENT WILL CONTAIN IMPLIED ABUSE.

    Summary

    The Handplates AU by Zarla is a pretty dark place, and it looks like Dr. Gaster will never reveal his secret to anyone. But, what if he got caught...?
