I recorded myself cooking in my gaster cosplay, but I didn't have the right pants (or shirt) clean, sooo this happened.
(My ver of gaster is an egg monster btw)

W. D. Gaster's glances at a void similar to deltarune's starting screen with the faux-vessel creation. His back is turned towards the viewer.

Serif and Gaster are both leader-types yet with different sets of values and approach to the world. One letter off and yet so many differences.
