Summary
After countless resets and endless repetition.. something has changed. The timeline has began shifting, changing its path for the first time in a long time. A new path Flowey hasn't seen before.
Well, it might take Clover longer to reach Asgore but Flowey has all the time in the world after all. And seeing something new finally happen has piqued his curiosity. Drawn in by the unfamiliar, Flowey watches with morbid fascination as Clover is not able to give up his soul this time. Encounters shift, monsters react differently, and the world itself begins to remember things it was never meant to.
Events shuffle. Characters act out of turn. Rooms appear where there were none. And for the first time in countless resets, Flowey doesn't know what comes next. Clover's fate is uncertain. Though Flowey knows he will get those human souls, no matter what.

Summary
Existe uma história que todo mundo conhece, uma que não precisa ser repetida. Mas o antigo misturou-se com o novo, dando à luz uma obra composta pelo imutável e por aquilo que mudou. Oito humanos caíram. O primeiro foi perdido, assim como seu irmão. Mas último não era mais o mesmo. E um dos outros seis era um pecador. A história que todo mundo conhece ainda existe, mas mudada. Transformada. Não é mais a mesma história, mas, ao mesmo tempo, é. Medos antigos e memórias ruins transformaram-se em agressividade e raiva. Certezas e fé transformaram-se em dúvidas e receio. Uma jornada difícil transformou-se numa jornada ainda mais difícil... mas muito mais recompensadora.
E com tantas coisas iguais misturando com coisas transformadas, eu não consigo não me questionar: o que mais vai se transformar? E o que se tornará?

Summary
Two people of completely different backgrounds and ways of existence die at the same time, in almost the exact same manner. Due to a grand, universal, mathematical error, they are now forced to live out their lives sharing a single consciousness and body. For the first time, someone is able to understand his speech. For the first time, someone is able to understand things from her perspective. Initially spiteful and overly bitter to one another, they grow attached to each other's company. What would happen if they die? How much does someone have to contribute to be deemed worthy of respect and understanding?
A commentary on loneliness and the plight of the foreigner.
A love letter to the fanfics I have read, connected with, and grown to love.

Summary
Frisk could feel Chara narrowing their eyes at them. "Seriously, can you please take that stupid bandanna off your head?" Chara sneered. "It makes you look ridicul-"
"Mandanna," Frisk interrupted.
“…excuse me?”
"Mandanna. Not bandana."
”Are we seriously gendering the bandanna just because it has abs on it?”
"Yup!"
”…I really wish that others were able to hear your sass.”
"I don’t know, I kinda like the idea that you’re the only one getting to see this side of me." Frisk looked in the window of a house they were passing by, winking at their reflection in it. "Makes you special, doesn’t it?"
”I- Stop flirting with me. I’m a dead person’s voice in your head!”
"No."

Summary
It was hard to explain, exactly.
A feeling. Walking into his room and his clothes not being where he left them, the bed messy and unmade. His favorite seat having a new indent in it. Mostly-empty bottles of condiments in the fridge, a spare pair of shoes by the doorway. A glimpse of bone as he walked up the stairs. His brother talking about things that Sans didn’t remember. Hearing people use his name for someone else.
A ghost living in their house.

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
Life is a funny thing. Sometimes people grow up and go to school and have a career, some become travelers, and some find solace in a domestic lifestyle. Others are born and then turn into a Monster when they were seven. (Hey. Thats you.)
Monsters were released from the mountain 16 years ago and when they were released, boom! A small percentage of the world turned into monsters overnight. You considered yourself a monster more so than a human. Especially after your mother dropped you off at the facility, and didn't look back. And after all this time, all there is to do is look forward.
