Ultra-detailed 3D model of a large six-legged alien predator inspired by a panther and a reptile. Smooth, glossy black skin with subtle bioluminescent blue patterns along the spine and limbs. Extremely muscular build, wide jaw with long, sharp teeth, and four mandible-like appendages flaring from the neck. Long flexible tail with a spiked tip, clawed feet, and an aggressive, primal facial expression. Standing in a neutral pose. No background, studio lighting. Cinematic quality textures for skin, teeth, claws, and bioluminescence
