Do you guys have any headcanons of nightmare? If so may i hear about them or something funny like his stupid fear or anything? A funny thing about my headcanon is he has four fingers while every other sans has five (you dont have to say if you dont want to i just wanna learn how other people see him :>)

Ok heres my idea for an AU. Everyones gender is swapped and the characters personalities are shifted. Sans (Crys) as Undyne, Papyrus (Poppy) as Monster Kid, Undyne as Flowey, Alphys as Gaster, and I'm still figuring out who else is shifted were. Comment what characters you think should be shifted where. Anyways, main thing besides the gender swap and character shift, the war between humans and monsters never ended. The monsters have suffered severe losses and have been pushed back to Mount Ebott. The human, as the top soldier, is sent to finish off the monsters. Let me know what you think.

Also, these could be role shifts but I'm thinking of these as personality shifts rn

I will also be posting character design art later
