Regenbogen-Einhornkatze, die über einen leuchtenden Fluss rennt

Create a stunning, realistic depiction of a unicorn-cat hybrid, featuring the compact, agile body of a normal house cat with a full spectrum of rainbow colors—red, orange, yellow, green, blue, indigo, and violet—shimmering across its fur, each strand reflecting light naturally. The unicorn-cat has a single spiraled horn prominently positioned on its forehead, glowing softly, adding a majestic unicorn touch to its feline form. The creature is captured mid-run atop a flowing river, its small paws barely touching the water, which ripples and transforms into vibrant colors matching its coat as it moves, creating a mesmerizing trail of rainbow hues. The background is a vast galaxy-colored night sky, filled with deep purples, blues, and hints of pink and teal, adorned with twinkling stars and swirling nebulae, enhancing the magical and otherworldly atmosphere. The unicorn-cat’s mane and tail flow dynamically with the motion, blending seamlessly with the cosmic backdrop. The overall mood should be dynamic and fantastical, with a focus on the realistic textures of the fur and water contrasted against the ethereal galaxy setting.
