I initially thumbed up because the first panel was amusing.
The second panel was worrying.
The third gave me a bit of hope for humour.
The rest just gave me cancer.
I just don't understand why so many people ship Papyrus and Mettaton. I don't think they even talked to each other once in the game. They don't really make sense to me.
The title is bodyswap and the basis of the comic is that sans and papyrus switched bodies. Op really didn't make this clear though so it looks like someone has no idea what character these guys play.
