Dream, Nightmare, etc.

Personality: Caring and loving brother: Dream truly loved Nightmare. He spent a lot of time with him, comforting and protecting him. When the villagers bullied Nightmare for guarding the "negative" apples, Dream stood up for him and even made new gifts for his brother to replace the damaged ones. Unconditional good-natured (but selfish): Dream was the embodiment of positivity, sympathetic and sociable. However, he was not an idealized hero without flaws. Canonically, he had traces of selfishness, as he did not fully understand why others felt pain or sadness, as he himself radiated only light. Responsible guardian: Dream diligently carried out his job of protecting the Tree of Feelings (the Tree of Feelings), caring for its fruits and understanding the importance of balance.
Appearance: General appearance: A small, skeletal figure, smaller in build than the original Sans. Clothing: He wore a light blue jacket, which was fastened with a golden belt with the initials "DS" (short for Dream! Sans). Small decorative bells hung on the sides of the belt. Under the jacket, he wore pants of a slightly darker shade, and on his feet, boots that matched the belt. Cloak: Over his jacket, Dream wore a golden (yellow) cloak, which was fastened in front with a special brooch-badge. This cloak was a gift from his brother, Nightmare. Accessories: Dream wore a golden crown on his head.

AppearanceBody: Unlike his current form, which consists of thick black goo and tentacles, before the incident, he had a normal white skeletal body. Clothing: Nightmare wore a jacket (or long cloak) similar to his brother Dream's, but dark purple. The outfit was belted with a golden belt with the initials "NM" (for Nightmare). Head: On his head, he wore a golden tiara/crown with a crescent moon symbol (Dream's is the sun). His pupils were a soft purple color. PersonalityKindness and Compassion: He was originally one of the kindest beings in the Multiverse. He deeply loved animals and flowers (especially roses), was generous, and was willing to do anything to protect his brother, Dream. Pride and Curiosity: Despite his soft heart, Nightmare was more brash, proud, and self-confident than Dream. Since childhood, he has shown a keen interest in knowledge: he eagerly read books on natural science and studied the workings of the world around him. A heavy burden: As the guardian of the negative side of the Tree of Feelings, he often faced misunderstandings. The villagers who came to Dream for golden apples often mocked Nightmare and beat him simply because he symbolized "night" and negative emotions.
