Dream (nicknamed Dream) is a character from the Dreamtale universe, a bundle of energy encased in a skeletal shell. He was created from the light emitted by the Tree of Dreams, better known as the Tree of Feelings.

Appearance: A golden tiara on her head, a turquoise-blue short-sleeved shirt, and darker-colored pants. On her waist are spheres containing each person's hopes and dreams.

Dream doesn't have the soul of a monster or a human. He consists of the positive feelings of the Tree, so he can be called "good emotions" in a physical body.

Capabilities:

1. Absorbing Happy Emotions. Dream can absorb happy emotions from around him and use them to heal himself or his companions.

2. Increase speed and strength.

3. Travel through alternate universes. Dream can only travel to universes that contain positive emotions.

Nightmare is a character in the Dreamtale 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 on his back. His left eye constantly glows blue.

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 Negatale.
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 (both Nightmare species)
Zz: Sagittarius♐

Ink!Sans (from the English word "ink") is an out-of-code character in the Undertale AU universe, an alternate version of Sans from Undertale. Created by Comyet, who created the InkTale universe.

Description:
Exists outside of existing universes, but can interact with them. Supports artists so they can continue to contribute to the fandom. Doesn't create alternate universes (AUs), but protects them from anomalies that undermine the original plots and creators' visions. Ink's pupils change shape and color almost every time he blinks. The shape of the pupils varies depending on his mood, but they are never white.
The little rainbow bottles on the work belt are paint bottles with heart-shaped stoppers.
Under the clothes are ribs with "tattoos" in the form of strange ink marks.
On his back is his signature weapon—a brush (which Ink calls Broomy). He's passionate about art and enjoys motivating others to do the same. Forgetful, he sometimes stops mid-sentence to try to recall what he said a few seconds ago. He's cautious in encounters with enemies—he doesn't attack first, but mostly tries to figure out their motives and talk to them. He's afraid of whiteness, the absence of any form around him, loneliness, and vast empty spaces.

Capabilities:
Teleportation - Ink can appear in any universe from any liquid mixed with paint.

Creating objects with a brush and bringing objects (but not characters) to life.

Create gaster blasters that shoot ink that hardens on contact.

Script Reading - Ink can read the scripts of all existing AUs in Undertale, and thus knows the fate of all their inhabitants.

Guardian of Creativity - Ink ensures that the flow of creativity continues and encourages artists to keep creating.

Art Block Fighting - Ink battles enemies with physical bodies to keep the entire AU running.

Protecting the universes from Error!Sans, who believes that all universes except the original one are trash.
