This is a WIP so don't judge.
I don't own any of the characters and concepts
All rights to Toby Fox.
I also don't own the idea of Underfell.
I did not create Underfell and do not own any songs or ideas.
What if Asgore knew that Sans was a weapon built by the scientist before Alphys? What if Frisk couldn't fix the gap between humans and monsters? What does Protocol Soldier Boy mean to them?
Plenty of cursing and some violence. That's really all my stories ever are.
