Nightmare Sans

## Profile

### Personality

Nightmare's demeanor is completely different to as he was before corruption took over his body, though they still share some similarities. Even before the bullying and corruption, Nightmare has been the more cocky and proud between him and Dream. He tries to remain serious, and has always been interested in learning- both normal and corrupted.

He is deceiving without remorse, willing to do anything to get his way and destroy every universe with negativity. He can pose as erratic, unpredictable, and evil. The corrupted Nightmare never lies, only hides the truth under coated words. He shares no respect for any other monster he encounters, including Error or anyone who protects the multiverses.

## Appearance

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)

## History

### Past

Passive Nightmare decided he had had enough and tried to prove himself. He was tired of all the hatred; he couldn't even think straight anymore. Everyone respected Dream (or so he thought), so he was certain the only way to prove he was not some useless punching bag was to show everyone that he could protect the same things he did. Nim had explained them many things about how the tree worked, such as what kind of effects the apples had on people, etc... but she never told them they could not touch each other's apples, or else they would turn into the opposite energy. The apple he took got corrupted, and then so did every other apple, and then so did the tree itself. It stopped spreading positive energy through its roots, so boundless negativity began to contaminate that entire world. Everyone went silent, everything started to wither and even the sky began to darken, which was what Dream and Neil saw. Dream's immediate thought was that something had happened to his brother. Neil tried to stop him from rushing back to the village, fearing what was out there, but that didn't stop Dream from running off, and against his better judgment, Neil decided not to follow.

Dream came back just as the negativity started affecting the nearby people as well. They were already filled with unreasonable hatred, but that hatred quickly turned into mindless rage toward the one being they loathed and blamed for the loss of their world. They were all going to kill Nightmare, and Nightmare was not going to do anything to defend himself. He was too scared, too ashamed, too helpless, because all he had ever known was that he was there to be hated and he had just destroyed the one thing he was meant to protect. Dream tried to stand in front of the villagers, trying to keep them away from his brother, but they just walked right through him, knocking him unconscious in the process.
‘Nightmare heard the voice of a man coming from the black apples, telling him to eat them and get stronger or he would die. It was the voice of a man, very different to mother’s.’ - Page 28 of the Dreamtale comic. This was the voice of the man who murdered Nim. As known as seemingly one of Quetzalcoatl’s creations, The killer of their mother. So utterly corrupt, His essence, conscience and soul was absorbed into the negative side of the tree when he died beside it, and had remained trapped within the negative side of the tree ever since, giving said side more power than it should have had without Dream or Nightmare ever knowing so. This is who you know as corrupted Nightmare.

As Nightmare ate more and more apples, his body began to *break* as it couldn't withstand the energy of it. The power consumed him, his body snapped and cracked apart. He let this person take control as he promised to protect him from everything. This, of course, was a lie, And with it, the Nightmare Dream knew as his brother was gone*.*

Corrupted Nightmare is not actually protecting Nightmare. He's a horrible man, who wants every single person in the multiverse to be negative, and erase positive feelings from existence. **He killed their entire AU.** He used Nightmare's fear, Nightmare's pain, Nightmare's suffering; he manipulated him, and used him to gain a body.

## Abilities

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.

He can also fall/jump from a great height without sustaining damage. Whenever he falls/jumps, the ground underneath him breaks.

### Weaknesses

Positivity

He's disgusted by positive emotions. If he can't make them negative, he'll just leave, since it weakens him.

He also is completely unable to enter positive AUs, a barrier prevents him from entering. A similar thing happens to Dream with negative AUs

Because he only has one eye to see, he has a blind spot.

## Trivia

* Positivity may be his weakness but even that isn’t 100% effective
* Nightmare sans actually hates himself
* Nightmare sans likes black coffee
* Nightmare and Dream share the same birthday (December 21) Making both him and Dream a Capricorn
* Sometimes Nightmare's tentacles can lose control when He is caught of guard or feels a lot of negativity at once.
* His goop is an extremely powerful shield that renders him invulnerable to most things; if he were stabbed with something, his body would absorb it and there would be no damage.
