About Underswap

Underswap is an alternate universe (AU) of Undertale. The concept was made by the Tumblr user Popcornpr1nce when they drew Sans with an attitude and attire more typical of the original Papyrus and later drew Papyrus in Sans' role. Eventually, they drew every main character with their roles swapped in pairs.

In the present day, its creator has abandoned it because of how the Undertale fandom treated this AU. However, I reunited all the basic concepts of Underswap in this document.

And what's Underswap PLUS?

Underswap+ is a series where we try to recreate key moments of the story as if it were recorded from a real game. As there's info that was never revealed about Underswap, we attempt to fill the gaps with what we think would make the most sense. That's the reason for the "plus"
