Envision a towering alien creature resembling a dinosaur with vibrant, bio-luminescent scales covering its massive, sinewy body. It stands majestically under a twilight sky on a distant planet with an atmosphere tinged in hues of purple and teal. Its elongated tail sways gracefully as it moves with deliberate, predatory elegance. The creature's eyes glow with an otherworldly intelligence, and intricate, swirling patterns can be seen etched along its leathery skin, hinting at an ancient, cosmic origin story hidden within the depths of space.
