A detailed 3D model of a space marine with a shark head, designed as a deep-space explorer. The character has the powerful body of a human soldier wearing advanced sci-fi armor. The armor is white with bold blue accents, featuring reinforced shoulder plates, glowing interface panels, and subtle scratches from space missions. The shark head has smooth gray skin, a powerful jawline, and sharp triangular teeth, with dark intelligent eyes scanning the environment. A compact jet-pack and exploration gear are attached to the back, including small lights and sensor devices. The stance is confident and alert, as if ready to explore unknown planets and cosmic frontiers.
