Ambassador and I are currently researching the Mother games, to compare them to the Halloween Hack that may or may not be linked to Undertale and Deltarune.

I believe Gaster is a fusion of Doctor Andonuts and Giygas, a ghostly amalgamate. Which would explain his two faces and two voices at the start of Deltarune. And that the Hack indurectly tells Gaster's origin story in its Neutral Ending.

My ongoing notes on the Mother games (Mother 1 is currently done, Mother 2/Earthbound in progress, Mother 3 to come) can be found here: https://docs.google.com/document/d/1a50WdENFWoVaViDYB52wvwCe3aIZu3GWL-Hsq4qB8m4/edit?usp=sharing
