Appearance: Sans is a rather short and "big-boned" skeleton whose hands strongly resemble mittens. He is always seen with a wide, toothy grin on his face. Sans wears an unbuttoned blue jacket (or sweatshirt) with a gray hood and a white T-shirt underneath, black shorts with white stripes, and a pair of slippers. His black eye sockets contain white pupils that disappear when he is serious or angry. When using telekinesis, Sans's left eye develops an iris, flashing blue and yellow (the colors of patience and justice), while his right pupil disappears.

Personality: Sans is a very laid-back person. He enjoys sleeping, which he does during his breaks at work. He's known for his jokes, which his brother, Papyrus, greatly dislikes. Sans is also kind and friendly. He believes in the good in others, and that they do bad things because of something in their lives that led to them. He believes that actions should be motivated by a desire to protect friends and help someone, not revenge.

Sans once said he doesn't like making promises, but when he does, he tries to keep them to the end. He said the only thing that saved the protagonist from death was his promise to Toriel to protect the fallen. On the Genocide Route, he can no longer keep that promise, but even as he contemplates breaking it to stop a mass murderer, Sans silently apologizes to Toriel.

Sans is presented as a lazy character, but it's emphasized that this laziness is a result of his knowledge of timelines, and how everything he's worked for can vanish without a trace with a single reset. Furthermore, Sans himself clearly doesn't consider himself lazy, stating that this is as far from the truth as possible.

Sans apparently has a scientific background. Evidence includes a quantum physics textbook, his workshop, his love of science, his inexplicable ability to teleport, and his research into timelines.

Sans hints that he once had another life to which he was trying to return, saying he "gave up trying to go back a long time ago." When Sans becomes a lost soul, he tells the protagonist, "You'll never see them again." Although it's unclear what exactly Sans is trying to return to.

Capabilities:
Sans has the ability to use "shortcuts," which allow him to quickly cover large distances in a short time. Furthermore, Sans is capable of appearing in multiple locations within a single room at once (as seen in the room leading to the mysterious door in Snowdin Forest), suggesting that Sans possesses the ability to teleport. Doggo also alludes to this by claiming that the skeleton sometimes appears nearby without any indication of approaching (this line can be heard if you speak to Doggo in Grillby's Pub after sharing a meal with Sans, or if you ring the bell at Doggo's post repeatedly). Thanks to his "research," Sans is knowledgeable about timelines; Flowey notes that the skeleton is the cause of most of his resets. His knowledge of timelines makes him more observant, allowing him to detect when the protagonist is acting unusually simply by looking at their facial expression. In the Genocide Route, Sans uses the protagonist's facial expression to determine how many times he's killed them. Sans is able to dodge the protagonist's attacks, which distinguishes him from other enemies in the game. However, his combat power is quite energy-consuming, and by the end of the battle, he shows visible signs of fatigue, causing him to fall asleep mid-battle.

The Gaster Blaster is a weapon Sans uses in combat. As its name suggests, it's somehow related to V.D. Gaster. It's a fairly fast-moving ranged weapon of varying sizes and purposes. Some fire two or more shots. The blaster resembles the skull of a dog- or dragon-like creature, firing laser beams from its mouth. When fired, the lower jaw splits in two. Sans uses it in both standard and blue modes. The beam's width directly depends on the blaster's size. During his final attack, Sans uses a large number of blasters firing in a circle. During and after each shot, the blaster's eyes begin to flicker.

Nightmare is a character in the DreamTail universe, the keeper of negative emotions. Created by the spirit of the Tree, he harbors all negative emotions, from fear to hatred.

Nightmare is Dream's brother.

Nightmare was created to protect the dark side of the Tree of Feelings. Along with his brother, Dream, they guarded the tree as guardians.

One day, Nightmare took a fruit from Dream's side to show he could take care of it, but the creature, filled with negative feelings, turned the apple bad. Everyone blamed Nightmare, so he ate all the fruit from the tree. That's when Nightmare became the man we know today...

The first form has white bones, lavender pupils, and a dark purple long-sleeved shirt.

In his second form, he's covered in a shell of hatred and has four tentacles extending from his back. His left eye constantly glows blue/turquoise.

Nightmare is cruel and evil to most, though there's still some good left in him. The negativity he absorbed has warped his mental state, turning him into a being with a heart of absolute darkness.

Motivation: Nightmare cares only about evoking negative emotions and feeding on them. Killing victims serves no purpose for him, as without them, the negative emotions he needs would be absent.

Capabilities:

1. Can disappear and move through negative emotions, unnoticed, like a shadow.
2. Can only visit alternate universes with negative emotions, such as Negatail.
3. Uses tentacles to fight and intimidate enemies.
4. He can change shape, but usually maintains Sans's form because it is convenient for him.
5. Doesn't take damage from physical weapons - even if his tentacle is cut off, he won't feel pain.

Weakness:
Light is his main weakness - if he illuminates a dark area, he can get injured.

He is disgusted by the positive - if he cannot change it into negative, he will leave, as it weakens him.

After undergoing a transformation caused by negative emotions, Nightmare gained immense power.

Date of birth: December 21.
Zz: Sagittarius.
