Description

Nightmare Sans is a version of Sans from another universe in the game UNDERTALE. Nightmare Sans is a skeleton measuring 1.55 meters, a very dark green color that appears almost black, has wide and long tentacles that can stretch and disappear at will, made of the same substance that covers him, negativity. Only one eye is visible, his clothing is also covered in the negative substance, although touching it does not cause it to disintegrate, only makes it feel somewhat slimy. He is the king of negativity and travels between alternate universes seeking to feed on those negative emotions in others. He has an opposite brother, Dream, who thrives on positive feelings. He is very powerful and uses bones and mainly his tentacles to injure others or defend himself; he is one of the most powerful Sans in the multiverse, although he avoids getting involved with others like Error. Nightmare Sans is very indifferent and usually insensitive, violent, and somewhat cruel. There are times when he is very silent and irritable.
