As a Bandai Spirits S.H.Figuarts interpretation, Build New World: Kamen Rider Grease's Kamen Rider Metal Build is rendered with a gleaming, chrome-like armor, deep black underlay, and gold accents that outline each plated segment. The helmet features a sharp crest and blue-tinted visor windows that give a menacing stare. The figure carries multiple points of articulation: ball joints at the shoulders, elbows, knees, and ankles, plus a torso twist and wrist swaps for dynamic poses. The surface finish combines glossy black, polished metal tones, and translucent blue energy parts for dramatic displays. Included accessories allow battle-ready poses.

In Build New World: Kamen Rider Grease, Metal Build represents a pinnacle of forged technology and a resolve to reshape a fractured world. This form emerges when Grease fuses with ancient machines, turning raw metal into a living weapon and shield. Metal Build operates with a cool, disciplined mind, using calculated strikes and modular armaments to overwhelm foes. The story follows his struggle to protect friends and to balance rebellion against oppressive forces with a desire to preserve hope for the common people. His journey confronts trust, sacrifice, and the cost of power.
