Following the May 2026 release of Zero-One, BANDAI SPIRITS' TAMASHII NATIONS is developing the second Kamen Rider Zero-One entry in its METAL BUILD die-cast action figure line: METAL BUILD Kamen Rider Ark-One. Japanese retailers APITA/PIAGO have now posted product information for the figure, which carries a suggested retail price of 33,000 yen, including tax, and is scheduled for release in April 2027!
Kamen Rider Ark-One made his debut in Episode 42 of "Kamen Rider Zero-One" (仮面ライダーゼロワン). The form is assumed by protagonist Aruto Hiden using the Ark Driver-One after losing his longtime secretary, Izu. Once committed to building a future where humans and Humagears could coexist, Aruto's grief gives rise to malice, allowing Ark to take root in his heart. Ark-One's design combines black-and-white armor with asymmetrical red compound eyes. His combat capabilities far surpass those of Kamen Rider Ark-Zero, allowing him to overwhelm multiple Kamen Riders at once. His signature finisher, Perfect Conclusion, unleashes a devastating indiscriminate shock wave.
Product designer Takato Yamashita, who previously worked on "METAL BUILD Kamen Rider Zero-One", returns to rework the articulation system established by the first figure. The design also incorporates extensive newly tooled parts, including the feet, chest armor, arms, head, and back armor. Ark-One's asymmetrical helmet and single red eye remain intact, while the wing-like folded back armor gains even greater presence through its enhanced mechanical detailing. Layered white armor plates give the chest a complex silhouette. Unlike the slightly raised red pattern seen in the original suit, this version recesses the entire design into the armor and extends its surrounding lines, creating a strikingly fractured aesthetic. Spikes projecting from the outer forearms further sharpen the black-and-white silhouette, while the hands feature exaggerated angular sculpting and menacing claw-like fingers.
The newly released product images also showcase several translucent red effect parts. These include long, razor-sharp claws extending from the arms, a circular effect corresponding to Zero-One's but representing Ark's malice, an eruption of red energy bursting from the left side, and a chest effect that makes it appear as though malice is exploding through a crack in Ark-One's torso. Combined with lunging palm strikes and airborne kicking poses, the effects capture the instant his malice erupts with every movement. The Attache Calibur from the previous release is also included, along with its own dedicated effect part. Progrise Key accessories in both open and closed configurations and a dedicated display stand round out the set.
