Power Rangers Zeo Series 1 was released in May 1996 shortly after the television debut of Power Rangers Zeo.
Early promotional materials from Bandai America showcased Rocky as Zeo Ranger IV and Adam as Zeo Ranger III. While this went largely unnoticed in the Spring toyline, it became a glaring error on the cards.
Each card has a Power Level (1 through 10 and then MAX), a Battle Gage (comprised of both color and number), and a Medallion (star, square, triangle, and double-bar). Using these values and symbols, the collector can play Super Battle.
