So now that I've played Delta Rune, I have a new theory on the mysterious character, W.D. Gaster My theory is that Gaster, Sans, Papyrus and the Gaster Followers originally came from the Delta Rune universe. In that universe, the monsters win the war and humans are trapped underground. Gaster travelled to the Undertale universe where he built the CORE and when he tried to teleport to a different universe, his time machine broke and destroyed the Delta Rune universe, trapping Gaster and his followers inside but Sans and Papyrus somehow survived and were sucked into the Undertale universe.

Evidence:

> Sans has a broken machine in his lab in Undertale which is probably, Gaster's broken time machine.

> There are no humans around in Delta Rune.

> Some of Gaster's followers are in Delta Rune.

> Sans and Papyrus "appeared out of nowhere" as said by the Snowdin shopkeeper so they could have literally appeared out of nowhere from an alternate universe.

> During the Sans boss fight he says look. "i gave up trying to go back a long time ago. and getting to the surface doesn't really appeal anymore, either.", meaning that he wanted to go back to the Delta Rune universe where he lived on the surface and he wouldn't want to go back to the surface in the Undertale universe because all his friends aren't there.

> Sans knows what the sun is but Papyrus doesn't because he was probably too young to remember as Sans called him his little brother in Delta Rune.

Hope you enjoyed my theory, leave your opinions below!
