passivechara:

I keep thinking about how mystery-man/Gaster has no nose hole or any teeth and how that is weird for a skeleton not to have those things, and while you could say it’s a side effect from getting violently ripped from reality, I think I came up with a more interesting option today.

What if instead of a humanoid endoskeleton like Sans and Papyrus are…

Gaster was instead a humanoid exoskeleton?

Toby Fox does work with Andrew Hussie and his webcomic includes a race of chess piece people called carapaces. And a carapace is the name for a hard shell of a creature.

So imagine a Gaster with segmented joints if you can.

I like this theory~
