Nightmare!Sans

Hentai Tentacle Monster. That's it haha

The thing with Nightmare though is that I have this thing where he and his aggro aggression form are two different beings. I don't know how to really explain that.

Name - Nightmare Joku

Age - 408 years. His canon age.

Sex - Male.

Sexuality - He is gay as fucc. Has never found sexual attraction towards the female sex. He finds their drama to be too much. (I'm a gal too ;) Don't worry, I ain't sexist)

General Appearance - Slick boi. He is covered in black goo from head to toe. Though, his clothes appear to not be affected at all. He has four tentacles which all seem to aimlessly wander around until he sharpens and aims them, to which they become dangerous and sharp enough to slice through most things. He wears a completely black version of Sans' clothes, which are black basketball shorts with no stripe down each leg, black slippers on his feetsies, and a black shirt with a black hoodie over it.

General Personality - He is calm and collected when he is around his gang, and it sometimes shows when he is fighting Ink and the other two Star Sanses. His 'insane side' is maniacal and deranged, although forced, to put on a threatening demeaner. He is caring towards those he has grown an emotional attachment to, such as those from his gang. He's also protective of them.

General Knowledge - Nightmare is really fucking smart. His creator, Nix, taught he and his brother all they needed to upon creation, which means how to have sex, aftercare, cuddles, math, science, etc. You name it, he can probably so it.

Background - Nightmare is the God of Negativity, and as far as anyone else knows aside from Dream, this form he takes on is the only form that he has.

True Background - The entire apple incident. Both Nightmare and Dream were two guardians that protected the tree of emotion, otherwise known as their creator. The two are not skeletons; they are beings of pure emotion created by the tree of emotions before she went into a state of comatose. However, when a village was formed around the tree, the two guardians were almost worshipped until social statuses and schools were formed. At this point, the two are a few hundred years old. The two started going to school to get an education along with the experience of being at school. This is when Nightmare begun to be bullied for his negative aura, to which he, nor Dream, could control, and vice versa for Dream. This went on for several years until he broke, and this is when he touched the golden apples on Dream's side of the tree. He panicked when the tree began to die as the others were also corrupted. The sky turned a brackish red color, and the village was pushed into panic. Immmediately, Nightmare was blamed for this event. He yelled that he didn't mean to, and until Dream got there, this is what he kept yelling, trying to stay away from the villagers that were slowly closing in on him. Dream had made it in time to see his brother eat the nightmare apple in his hand, and he watched him turn. Though, he managed to snag a golden apple before it corrupted. The whole village watched, terrified, as Nightmare turned into what he is known as today. In a sudden fit of rate, a tentacle, which he'd sprouted during his transformation, whipped out and sliced through the trunk of the tree of emotions, effectively cutting it down in one move. The motion of the cut made the tree fall forward, and it nearly hit Dream. Nightmare continued his rage, killing every monster he could see within the village, and Dream could only dodge and watch, horrified and clutching onto the apple in his hand. He quickly ate the last golden apple, making sure it was safe with him. The last thing Nightmare did was turn Dream to stone before he teleported out of the AU, leaving the destruction. It was several years before Dream escaped, and this was due to Ink finding the universe. Several years afterward, Error attempted to destroy the universe, but only managed a half-job on the highly unstable and destroyed universe.

Mental State - His mental state is a sort of calm insanity, though he does have his bouts of intense insanity that he cannot control. This is most often shown around others that are not his team, of which he is calm around. Though, he can be pissed off very easily. His mental state over all is extremely fragile.

Friends - He is frenemies with Error, and the entirety of his team are his friends. He cared about them, a lot.

Loves - I suppose you could say he still cares for Dream. He just denies it. He also cares deeply for his team, to a point that he would be internally devastated if he were to lose them all.

Fears - Philophobia; the fear of falling in love or getting an emotion attachment. Nightmare pushes everyone away because of this. Eremophobia; the fear of oneself, being alone, or of loneliness. It is similar to Autophobia; the fear of abandonment, though for Nightmare, he is more so afraid of being switched back to his passive side, which is where the fear of oneself comes in.

Causes For Said Fears - The whole apple incident can be an explanation for both fears.

Turn Ons - He loves the feeling of his thick tentacles going up his victim's entrance. He also enjoys the feeling of them being sucked on or deep throated. He likes to watch them get sucked into his victim's entrance, holding their legs up so he can see it happen. He also likes stuffing one up as far and as much as possible.

Turn Offs - When a tentacle is sliced off. This along with positive emotions, though not as hard as the tentacle part.

Kinks - Slight bondage, as well as tentacle play.
