I just had a theory,
In Undertale there is a story for Chara and Asriel showing how they attempted to free the monsters from the underground (as seen in the true pasafist route of the game). What if Deltarune exists in a world where they got out of the underground using the mixed soul of Asriel and Chara. It may seem like a stretch, but is it? In Undertale, when trying to figure out who Gaster is a lot of stuff realated to spacetime continuum so assuming that there is a different timeline where the monsters made it to the surface before Frisk even existed doesn't seem to hard to believe. The only problem is Sans, Papyrus and Gaster, if Gaster didn't have the chance to fall into his creation, then why do Sans and papyrus even exist in the Deltarune universe? That is why I came to YouTube. See if anyone can figure this out because I'm hecka sure I can't. And finding people in a theorist community is just the way to try and figure this crap out 😀
