Kamen Rider Build - Rider Hero Series (#23) - Genius Form (Bandai)Kamen Rider Build · Bandai

Bandai's Rider Hero Series #23 brings Kamen Rider Build in his Genius Form, part of a long-running toyline that has covered nearly every Rider form across the Kamen Rider franchise since 2000. The Rider Hero Series is known for its accessible price point and broad coverage of forms from across Showa, Heisei, and beyond, with many figures including a character detail card attached to the back. Kamen Rider Build Genius Form represents the ultimate evolution of Sento Kiryu's transformation, achieved through the fullbottle system at the peak of the series' narrative. The Build series centers on a Japan divided into three regions after a catastrophic event called Skywall, with Sento—a brilliant physicist suffering from amnesia—fighting to uncover the conspiracy behind the disaster while protecting humanity from Smash monsters. This figure stands approximately 170mm tall. As part of the Rider Hero Series lineup, it features limited articulation, consistent with the line's design philosophy focused on display and collectibility rather than extensive poseability.
