W. D. Gaster: the Heart, the Brain and the SOUL by WittyWind
Fandoms: Undertale (Video Game)
13 Aug 2025
Tags
Summary
“The weight of the head of a genius is equal to its value.”
W. D. Gaster didn’t want to admit it, but he could feel it, deep inside him.
His brilliance gave a future to the Underground, a machine that could convert the heat of the Earth into energy: the CORE. The other monsters would, then, use it as electricity, and bring life to their houses and their TVs and their cars and their cell phones.
But Gaster knew more. Knew better. The CORE had so much potential, so much to offer. That kind of magic had never been used before. Gaster didn't know if he could call it “magic”, even.
He was so valuable to the Underground, but… what if that made him dangerous? What would happen if he had discovered something that shouldn’t be touched, not even by monsters or humans?
W. D. Gaster didn’t want to think about it, but he could feel it, deep inside him.
What is the value of a genius, if he’s so terrified of the weight of his own head to ever use it?

Summary
Gaster watches, because it’s all he can do. Or rather, he does his best to, because working with the void is even more difficult than working against it.

Summary
Gaster is lauded as a brilliant scientist, and for good reason. But on his off-time, his genius engages in hobbies that the public might find... inappropriate. And the only thing more embarrassing for Gaster than the idea of the public finding out he's the number one creator of sex toys for monsterkind, is the idea of his protege Alphys finding out about the unconventional hobbies of her mentor.
Too bad for Gaster, Alphys is sometimes too curious for her own good. But maybe platonic discussion of sex toys can be a way to bond with your protege?

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
The King and Queen disappear seemingly overnight.
Despite the councils efforts, the two heirs attempts, and the long wasted work-nights of Governor Holiday, the Undergrounds struggles increase in severity until drastic measures are needed. After the ruling council's flimsy excuse for their royals' absence, trust in their organization drastically decreases. The Underground grows suspicious, divided, and restless. The Council's hand is all but forced to into a rushed coronation of the two heirs, asking all to leave the era of mourning behind.
Asriel and Chara step up to rule, but on the day of their coronation, a wounded creature of unparalleled power steps through the barrier. Widespread panic, the uncovering of a secret plot, and a growing feud between the two heirs split the Underground apart. Chara's tirade for justice leads them down a darker, darker path, leading a grieving Asriel to pick up the pieces.
When a new human enters the equation, Asriel promises to end this madness for good. Even if that means opposing his best friend, the royal guard, and the entire Underground in the process.
