Hey guys, Hydro here. Welcome to the Backbone Archive! This just an archive account i slapped together. Here you will be met with every single lost Undertale AU Disbelief-related backbone. If you would like to request a reupload, please provide the name of the backbone, the creator, and (if you have it), give me the mp3 file. Enjoy!

"Welcome to my archive, Human. It is where you will be broken. It is where you will give up your backbones."
— Papyrus greets the human, Undertale Infinite (LOL)
