Bioman’s Bio Dragon Menko Card and the Showa Collecting Scene

Choudenshi Bioman Bio Dragon Menko Card

Choudenshi Bioman and Its Place in Super Sentai History

Choudenshi Bioman aired on TV Asahi from February 1984 to January 1985, produced by Toei. It was the eighth entry in the Super Sentai franchise — Toei’s long-running tokusatsu series that began with Himitsu Sentai Goranger in 1975. Western audiences may know this lineage primarily through Power Rangers, which adapted the Super Sentai format for international markets from the early 1990s onward. Bioman sits well upstream of that adaptation, in the heart of the original Japanese run. The show also stood out for fielding two female warriors simultaneously — Bio3 and Bio4 — which was genuinely unusual for the era. Beyond Japan, Bioman was broadcast in France, the Philippines, Thailand, and Brazil, where it built fan communities that remain active decades later.

Bio Dragon — The Flying Carrier Behind the Mecha System

Bio Dragon is the Bioman team’s primary aerial base and carrier vessel. It does not transform into a giant robot on its own. Instead, it serves as the launch platform for two smaller craft — Bio Jet 1 and Bio Jet 2 — which combine in the air to form the giant robot Biorobo. Bio Dragon functions, in effect, as a flying aircraft carrier: the operational hub from which all of the team’s major mecha activity begins. This card’s illustration, with its distinctive multi-color striped design in blue, yellow, orange, and red alongside circular motifs, reflects Bio Dragon’s on-screen appearance. The copyright notice on the reverse — © TV Asahi / Toei — confirms this is an officially licensed product from the original broadcast period, manufactured during or shortly after the show’s 1984–1985 run.

Menko — A Showa-Era Format Unlike Any Other

Menko are flat, stiff cardboard pieces with origins in the Edo period. Children played a competitive game with them, slapping cards against the ground so the air pressure would flip an opponent’s card. By the postwar Showa decades, character menko — printed with imagery from baseball, anime, and tokusatsu heroes — had become a mass-market staple, sold through dagashiya: the small neighborhood shops that stocked inexpensive sweets and toys for children. Bioman menko would have moved through those shops during the mid-1980s, placing this card at more than forty years old today.

Menko occupy a distinct lane within Showa collecting culture, separate from capsule toys, food premiums, or vinyl figures. The format was almost entirely domestic — there was no significant export market — which means surviving examples carry a particular quality as documents of everyday childhood in Showa-era Japan. For fans of Super Sentai and Power Rangers history who grew up outside Japan, a card like this represents something that simply did not exist in their local market: an officially licensed piece of the original franchise, in a format unique to the culture that created it. For collectors focused on mecha and vehicle designs rather than character portraits, a card centered on Bio Dragon’s airship provides a visual angle that character-focused merchandise rarely offers.
