Summary[]
Nightmare!Sans is one of the main characters in one of the fanmade AUs: Dreamtale. 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 Sans 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 Sans 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!Sans 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.
