A nightmarish entity captures the essence of evil, inspired by Japanese Oni folklore. This portrait view showcases a highly detailed, hyperrealistic depiction with 8k resolution, akin to splash and concept art. The scene is set mid-shot, revealing an intricately detailed face with rich color depth, highlighted by dramatic side lighting. The 2/3 face angle adds depth and intensity, against a vivid and colorful background. The appearance is a grotesque amalgamation of misshapen features, with poorly drawn and distorted elements, showcasing extra limbs and a disfigured form. Anatomy appears incorrect and exaggerated, with mismatched, cross-eyed expressions and crooked features contributing to a haunting visage. The composition is off-center, with elements often out of frame, adding to the surreal nature. The creature's form is further marred by mutations and deformities, creating a sense of confusion with unrealistic, impossible body positions. Despite the chaos, the overall scene remains a nightmarish, hyper-detailed portrayal of an Oni-inspired being.
