Blader is a robotic law enforcement assistant operated by a specialized police unit officer. Its humanoid frame combines a blue-and-white color scheme with functional armor panels mounted over a black rubber suit, blending utilitarian robustness with subtle feminine contours like a tapered waist. The design integrates double-jointed elbows for fluid motion, a chest panel echoing Astro Boy’s aesthetic, and projectile handcuff launchers akin to those of *C.O.P.S.*' LongArm. Square-shaped thighs and mechanical detailing reinforce its practical, mission-ready silhouette.

Tasked with high-risk operations such as vehicle pursuits and neutralizing hijacked machinery, Blader demonstrates tactical precision. During a pivotal mission, it strategically deployed its projectile handcuffs to dismantle components of a stolen tank, showcasing adaptive problem-solving. The robot relies on direct handler training to execute tasks, operating through programmed learning protocols rather than independent AI, reinforcing its role as an extension of human-controlled law enforcement.

Mechanical designer Kazutaka Miyatake, collaborating with Shoji Kawamori, focused on realistic articulation, material authenticity, and near-future plausibility during Blader’s development. The design avoids overt stylization, emphasizing credible technology through refined armor textures and internally detailed mechanics. A 2018 pre-painted action figure replicated these elements, capturing pose versatility and intricate joint engineering to reflect Miyatake’s emphasis on functional accuracy.
