Nightmare Sans

Unlike Dream, Nightmare is very well-read and intelligent, as he has had the opportunity to study information and travel the multiverse for 500 years, spreading his negativity. Because of this, Nightmare acts like a fully grown adult (one could say he's an older brother to Dream). Abilities Nightmare is powerful enough to temporarily force his brother, Dream, to retreat from a fight. His aura can affect the entire universe he's in and many others close by. He doesn't need to move much to spread negativity, and he only does so to find people to torment. He can turn into a puddle and move around undetected. He can teleport through darkness. Nightmare can only visit AUs with negative emotions, such as Negatale. He uses negative emotions to manipulate people. He can change his form, but usually maintains Sans's form because it suits him. He can also split himself in half to force multiple selves to perform different actions. As one of Joku's animations shows, he can also absorb his slime into the ground, turning a large area into darkness.[6] He uses his tentacles to fight and intimidate enemies. The black slime that surrounds him is an extremely powerful shield, making him invulnerable to most things; if he were pierced by anything, his body would absorb it, and no damage would occur. This applies not only to physical but also magical ones.

He wears rings and bracelets. Family: Nim - mother; Dream - brother. Likes: Negative emotions. Dislikes: Liars, traitors, positive emotions. Personality: Initially, even before the bullying, Nightmare was a rather daring and very self-confident brother. He always wanted to learn something new, even if it was something dangerous or not very good for a variety of purposes. This habit has been passed on to the current Nightmare, as he reads books from time to time. Nightmare is quite attracted to negative emotions and will do anything to obtain as many of them as possible. Killing victims is pointless for him, as without them, the negative emotions he needs will not be there. However, he kills those who break the contract with him, or makes him remember what he was like in the past, before corruption, or when he is angered (though in this case, he will still try to make his victim suffer and experience the deepest negative emotions, such as doom, despair, or other similar emotions).

Nightmare never lies, he only conceals the truth. He takes deals very seriously, which is why he kills those who break them without question.

Although Nightmare is incapable of showing sympathy for anyone, he can, in a sense, "empathize" with those who share his fate—the rejected and mocked outcasts of society. Seeing such scenes, Nightmare flies into a rage and kills without hesitation anyone who has bullied those like him in the past. This is his only sign of weakness and fear, though he tries to deny it, despite fear also being considered a negative emotion.
