The Nightmare Court

Nightmare Sans, also known as Nightmare, is the main antagonist in the webcomic Dreamtale. He was once a kind being created by the Tree Spirit, tasked with protecting the side of the tree connected to negative emotions. However, after consuming all the negative apples, he became corrupted and now seeks to eliminate all positive emotions.

HISTORY

Nightmare was born a conceptual flame from his mother: Nim. Nim created both Dream and Nightmare with the sole purpose to protect the Tree of Feelings. Since Nim was dying in that moment due to a conflict with an entity filled with Negativity, Nim attempts to find a vessel for both these flames. They initially attempt to make them stay in a human vessel, but since there were too little exits to emit both of the beings power and due to their fragile durability, the human vessels exploded.

However, Nim came across the Undertale Multiverse and saw a little skeleton called Underswap!Sans. She replicated the little skeleton's appearance and tried to fit the souls of Dream and Nightmare into it, and it worked. After some time, Nightmare!Sans was usually the more shy and quiet brother whilst his brother Dream was extroverted and joyful, helping out the villagers while also spending time with his brother. The villagers however, disliked Nightmare!Sans, and bullied him constantly for years without Dream's knowledge to the problem. This bullying and harassment was due to the fact that Nightmare!Sans was usually seen as a negative side to what was positive, and the villagers disliked this. This bullying got to the point where Nightmare!Sans had enough, and wanted to prove himself worthy that he was just as good as his brother.

However, he wanted to prove this by grabbing one of the Tree of Feeling's positive apples, a type of apple which were akin to Dream, and which made up the majority of positivity throughout Dreamtale's Multiverse. This corrupts the whole entire tree, rotting the tree entirely while also turning all the apples on the tree black. This causes the sky to turn red as a result, and also made the entire universe around them lose any signs of positive feelings due to the lack of thereof.

This caused the people of the village to rush towards Nightmare in anger and hatred, due to his their belief that Nightmare destroyed their tree forever and that this was all his fault that they felt so negatively. However, before his timely demise, Nightmare heard a voice...it was the man who fought Nim. Although, as a voice instead. It came from the apples.

The man's voice told Nightmare that if he didn't eat the fruit, he would die from the people. He should eat the apples to become stronger than them. Nightmare obliged. However, eating the apples was what made Nightmare into what he is today. As nightmare kept eating more and more apples, black lumps started to appear. The little guardian that once was at peace was now beginning to change. All this black concentrated negative energy started to ooze out of the skeleton so rapidly that his skull started to crack due to not being able to contain it all. At this point, Nightmare couldn't stop eating the apples and his fear of dying and despair turned into hatred. A terrible pain went throughout the skeleton's body once he ate the last apple. He was addicted to this raging power that was consuming his body. 4 tentacles of pure darkness came out of the tiny skeleton, breaking some ribs and causing Nightmare so much pain. Once was the little guardian was now a creature with a negative aura so big it caused anybody nearby to feel panic and fear. Nightmare was now corrupted with pure negativity. In present-day, Nightmare has found the Undertale Multiverse, and his main mission is to make everything around him feel negative emotions for all eternity, making him one of the biggest threats to the multiverse today.

APPEARANCE

Nightmare appears with a design similar of that of Classic!Sans, however his entire body is made out of a black, sticky, tar-like substance. with his hoodie, shorts, only being visible which are the same black color as his body, The similarities end here, as his left eye is completely covered in the "goop", which Dream!Sans easily takes advantage of when he shoots at him from that side. while his right eye is entirely black with a light blue pupil He also has appendages that grow from his back, made out of the same substance his body is made out of- and if the environment is negative enough, not only can he create more tentacles out of his back- he can also use his goop to shapeshift into other people and even become massive-sized.

Nightmare Moon also known as Moon is a major antagonist in the 2010 animated series My Little Pony: Friendship is Magic. She is the corrupted form of Princess Luna, the younger sister of Princess Celestia, who was consumed by jealousy toward her older sister. As Nightmare Moon, she serves as Celestia’s archenemy.

HISTORY

Long ago, Luna and Celestia ruled as the diarchs of Equestria, a land inhabited by ponies. Every morning, Celestia raised the sun, and every evening, Luna raised the moon. Together, they kept the balance perfectly.

Over time, Luna noticed that ponies were awake to enjoy the day and praised Celestia’s work, but always slept through the night, “shunning” her. Resentment and jealousy began to grow in Luna’s heart.

Eventually, Luna’s jealousy reached its peak. She refused to lower the moon and challenged Celestia for sole rulership of Equestria. The darkness within her heart consumed her, transforming her into Nightmare Moon—a black alicorn of pure darkness. Celestia tried to reason with her sister, pleading for her to lower the moon, but Nightmare Moon declared her only duty was to destroy Celestia. She attacked with powerful magic beams, eventually overpowering Celestia.

With no other choice, Celestia used the Elements of Harmony to banish Nightmare Moon to the moon, creating the celestial phenomenon known as “the Mare in the Moon,” a unicorn’s face imprinted upon its surface.

APPEARANCE

Nightmare Moon is a tall, imposing pony, equal in size to Celestia, with several physical similarities. Her fur is pitch black, and her mane and tail flow like a starry midnight sky. She wears light blue armor with a moon emblem on her chest and a helmet on her head. Her eyes are reptilian, with slit pupils, giving her a fierce and intimidating look.

PERSONALITY

Nightmare Moon is prideful, cunning, and intensely vengeful. She is consumed by jealousy and ambition, driven by a desire to assert dominance over her sister Celestia and the world of Equestria. Her intelligence allows her to manipulate others with precision, exploiting weaknesses and fears to achieve her goals.

She thrives on intimidation, using her presence, voice, and magic to instill fear in both allies and enemies alike. Nightmare Moon is deeply strategic, patient, and calculating, often waiting for the perfect moment to strike or manipulate events in her favor.

She is also highly theatrical, enjoying the dramatic flair of her own power and presence. Nightmare Moon can be cruel, sadistic, and relentless, yet she is disciplined and precise, knowing that brute force alone will not always secure her victory.
