The Hokuto no Ken Rei figure from the Hokuto Musou Revoltech line presents a compact, dynamic 145 mm sculpture that captures Rei's cool, disciplined demeanor. The sculpt by Kaiyodo emphasizes a lean, athletic build with well-defined musculature, a poised stance, and a calm facial expression framed by short hair. The paintwork emphasizes contrast—dark undershirt against lighter outer garb and detailed belt accessories—while the Revoltech joints are cleverly concealed to maintain seamless lines. Included accessories include multiple interchangeable hands and weapons, allowing a spectrum of action poses from swift striking moves to guarded stances. The overall finish conveys Rei's ninja-like precision and resolve, blending anime accuracy with the brand's characteristic articulation for impressive display.

The Hokuto Musou variant of Rei carries forward this legacy with a design that embodies his swift, precise fighting style and unwavering resolve, offering fans a tangible embodiment of his role in the story.
