The original Nightmare Sans AU, often called \u003cem\u003eNightmare's AU\u003c\/em\u003e or the \u003cem\u003eDreamtale AU\u003c\/em\u003e, was created by Joku and centres on two brothers: Dream Sans and Nightmare Sans. Where Dream embodies positivity, Nightmare is corrupted by the negativity of the multiverse and becomes a powerful, brooding villain across many fan stories and comics.\n    \u003c\/p\u003e\n    \u003cp\u003e\n        The \u003cb\u003eCat Nightmare Sans\u003c\/b\u003e spin-off reimagines this already popular character as a mischievous, four-tailed black cat. This version gained major traction through fan art communities on Tumblr, DeviantArt, and X (formerly Twitter), and became a runaway hit when interactive roleplay chats with \u003cb\u003eCat Nightmare Sans\u003c\/b\u003e on platforms like Character.AI attracted thousands of fans. In cat form, Nightmare retains his chaotic and shadowy essence but gains an endearing feline personality: he is feisty yet affectionate, loves sunbathing, drinks coffee, and plays with toys. His shape-shifting ability, allowing him to switch between cat, human, and other animal forms, made him a favourite subject for fan fiction writers and artists.

Over time, fans developed a spin-off interpretation of Nightmare as a four-tailed \u003cb\u003eblack cat plush\u003c\/b\u003e-style character, with a mischievous yet affectionate personality.

While the original Nightmare Sans is typically portrayed as an antagonist who feeds on negativity and leads a group of villainous AU characters, \u003cb\u003eCat Nightmare Sans\u003c\/b\u003e tends to be written with more moral complexity. Many fan writers portray him as a reluctant villain who retains a soft, almost domestic side in his cat form, enjoying coffee, napping in sunlight, and showing genuine affection toward select characters.
