Nightmare Sans, my newest main O.C!
Nightmare Sans, although its name sounds like she would be part of it, is not in Sans World. However, she is hinted at with the name 'Dream-Eater Sans' which Crazy Sans claims to have seen in his nightmares.

Nightmare Sans has a human form who is less likely to smile for unknown reasons. The human form has a blue left eye which she tends not to show.
Both have wings, but hide them

I hope you like it!
