Nightmare sans Fanart

This is just fanart of one of my favorite au characters of all time. Nightmare have gotten to be one of the most powerful Sanses ever next to cross sans. He reminds me of venom for some reason, and he is not symbiotic. And if there was an au where all the monsters became symbiotes, that would be interesting. Anyways, this is nomal fanart and so enjoy. :3 I'm not cringey btw. I'll try to draw Good maybe.
