Design a futuristic action figure named Vanguard Sentinel, standing 150mm tall. It features modular, detachable parts: head, arms, legs, shield, spear, and backpack. The armor is sleek gunmetal gray with deep blue accents and bronze trim. The helmet resembles a knight’s, with a glowing T-shaped blue visor. The chest plate has an angular design with a central energy core. Shoulders are broad and rounded; limbs are segmented with ball joints for full articulation. Accessories include a hexagonal bronze-edged shield and a silver double-bladed spear. A rectangular backpack mounts to the back. The figure is stylized, clean, and optimized for 3D printing and magnetic modularity. It blends futuristic military aesthetics with elegance and strength, designed as a high-end collectible toy suitable for customization and display. Prioritize symmetry, pose ability, and visual impact in the final model.
