W.D. Gaster has always been a mystery. Deltarune is chock-full of questions, and its most central seem to coalesce around Undertale’s Mystery Man. From his first “appearance” in Undertale to his constant references in Deltarune, I believe we’ve been slowly able to put together fragments of his true role. Today I’ll be going over what we know, and what it could mean for Deltarune’s future.

Deltarune has plenty of mysteries, but few are as subtle as the blossoming question of what happened to Onionsan between chapters 2 and 4. A fully optional character, Onionsan has teased players with hidden knowledge since her first appearance. Today we’ll be going over what we know about her, where you can encounter her, and where she may be in Chapter 5 of Deltarune.
