Yoshiya’s  Chief Smoky Robot was introduced during the 1950s, and boasted an array of  features including bump n’ go action, simulated steam-like smoke emanating from its head, and a translucent, illuminated cranium. Each puff of smoke was accompanied by a distinctive clanking sound. Adorned with lithography on its chest depicting electrodes and atom symbols, Chief Smoky Robot epitomized the era’s vision of technological advancement and innovation.

Part of Yoshiya’s skirted robot series, Chief Smoky Robot paved the way for subsequent creations such as Radical Robot, Mystery Moonman, Mighty Robot, and Mr. Chief. Sharing the same  skirted body design, these robots each had their own unique characteristics. While original Chief Smoky Robots command high prices in today’s market, a respectable reproduction was introduced by Ha Ha Toys in 2005.
