Rendered in a compact, highly posable form, this Robot Spirits ZGMF-X12A Testament Gundam captures the distinctive silhouette of the Astray prototype. The figure presents a crisp white and blue armor with gold trim accents and sharp, layered facets that suggest speed and durability. Its articulation covers shoulders, elbows, wrists, hips, knees, and ankles with a mix of ball-and-socket joints, allowing dynamic action poses faithful to the series. Detailing highlights the cockpit hatch, crest emblems, and weapon mounts, while a clean gloss finish on the armor mirrors the high-tech vibe of the ZGMF-X12A. Included accessories complete a faithful display of the Testament's combat readiness.
