Alright so, the spark notes version of the stuff one needs to know exept it's not sparknotes at all because I cannot be normal about this guy rn:

Nightmare!Sans is an Undertale AU thing specifically from an AU called Dreamtale created by @/jokublog (go read the Drematale comic go read it RIGHT NOW, it has epik sun and moon brothers angst– no pressure tho :D) that 13-14 year old me was absolutely insane over. For the purposes of this fic all you need to know is that he's an evil bastard bitch that psychologically tortures people for fun but rarely actually kills cuz dead people can't suffer anymore and that's no fun for him.

More seriously he's the embodiment of negativity, grows stronger from negative emotions and his mere presence amplifies them. His name is pretty self-explanatory, but Im not sure if he can directly influence what's exactly going on or if it's just his bad vibes that cause people to have nightmares, but this is my au and I get to do whatever I want. He's also a shapeshifter made of toxic sludge that burns if you touch it for too long. Oh, and the only one that even has a chance at fighting or fending him off is his twin brother Dream who is the guardian of positivity (which is as good as poison to Nightmare and the only thing that causes damage to him I forgor to mention!!) is not at all present in Sonic's world at the moment :)

#running from a nightmare #Idk a lot of additional stuff about him and Dream are accumulated fandom knowledge over the years #I'm sure I don't know a bunch of stuff too #and a lot of the facts also got obstructed with poorly mischaracterizing and infantalizing #yet unfortunately really popular fannon #and I don't even know which blog or post even begin hunting down to check for em!! #also uh #maybe like watch out #in a case the stars align perfectly and you mayhaps decide to check out pictures of him cuz #people can get really weird about him like super werid #aside from that there's really frequent body horror and gore #cuz the poor child he possesed went through some shit before dying brutally #IM RAMBLING #damn it this mf just gets me going insane fr fr #anyway
