I made this sweet boy from a thought I had.
I was like, anyone would know about pokemon X and Y. Then, I realized that there was no Ytale to Xtale.
So yeah.
Instead of sans being the last remanent of his au Papyrus is. Papyrus also has Frisk's soul as a little charm between his collar bones.
In Ytale, before the destruction of it, Gaster was obsessed with keeping everyone in the au happy and content. Then Gaster found out about the multiverse. Gaster found out about the lesser fortunate aus and attempted to help them. Gaster attempting to help them made the UNDO button.
The UNDO button could UNDO events that cause an unfortunate au to happen and allow the beings of that au to remember what their life was before the UNDO.
The UNDO button malfunctioned, causing it to UNDO Ytale.
Where was Papyrus during all of this? He was in another au helping some monsters out. He just got to his au as it finished collapsing in on itself.
His void looks like a very glitchy and poorly made video game zone with a lot of random white geometric shapes.
