Nightmare Sans

His current appearance is quite sinister, as he is covered in a thick goop. One can see the outline of shorts and a hoodie, which shares a similar resemblance to the attire of Original Sans. He is entirely black and goopy, with usually about 4 tentacles coming out of his back. His left eye is constantly illuminated in battle blue. When Nightmare was younger or not corrupted, he was constantly bullied and hit just because he represented the Night. He had a crown just like Dream, Purple clothing with a bit of gold accents. Black pants that where tucked into Purple Boots (with gold) Nightmare is very powerful. He is powerful enough to, trap people in stone (like he did to dream.) He has an army of dark Papyri, that are similar to Underfell Papyrus in stature. He can turn into a puddle and move around without being noticed, like a shadow. He is also able to teleport through the darkness. He can only visit AUs with negative emotions, like Negatale, and he can use bad emotions to manipulate people. He can change his form, but keeps his current form because he's comfortable with it. He uses his tentacles to fight, and make him look bigger than he really is. He can also whisper to people with ongoing negative emotions, as in mind controlling them. He's immune to weapons; if stabbed, it causes no damage and he'll absorb it. If not dropped, the weapon will be trapped in black goop and start to melt.
