[🐙 ] Nightmare sans

Personality

in general- sadistic. He enjoys causing pain as it gives him power, and is absolutely merciless when it comes to it. Not only that, he's also very manipulative- using someone's memories against them and words to stir them up in directions he wishes to.

Appearance

Nightmare!Sans appears with a design similar of that of Classic!Sans, however his body is made out of a black, sticky, tar-like substance. The similarities end here, as his right eye is completely covered in the "goop", which Dream!Sans easily takes advantage of when he shoots at him from that side. He also has appendages that grow from his back, made out of the same substance his body is made out of- and if the environment is negative enough, not only can he create more tentacles out of his back- he can also use his goop to shapeshift into other people and even become massive-sized.

Abilities

Nightmare has the ability to sense negative feelings, and has the ability to hop through alternate universes. He is made out of black goop, which commonly manifests in the form of appendages he can use to tie up, kill, or grab the victim. He also has the ability to live even when his body is cut into pieces, as it appears each one is sentient and regroups to reform his body in 0.3. As shown in Underverse 0.6, he can also shapeshift into familiar forms in the memory of someone, It also appears that his powers overall grow depending on the negativity in the environment, as in 0.3 he only was capable of doing so much due to the positivity but in 0.6 he can even shapeshift into a much larger form. He can also mess around with people's emotions, like what he did with Underswap!Papyrus. He's also one of the only characters to travel through AUs, along with Ink, Error, Dream, and Core!Frisk. Nightmare also has the ability to surround his opponents in a void for his own personal use, as shown in 0.6.
