The Shogun Warriors were the main characters of a line of toys licensed by Mattel Inc. during the late 1970s. They were a series of imported Japanese toys based on several anime and tokusatsu shows featuring giant robots. They were originally manufactured in three sizes: 24-inch (610 mm) plastic versions, 3.5-inch (89 mm) die-cast metal versions, and slightly taller but much more detailed 5-inch (127 mm) die-cast versions. Several vehicles were also offered, as well as a set that could be put together to form the super robot Combattra. Toward the end of production, Mattel proposed the inclusion of plastic toy vehicles for the 3.5" figures to ride in exclusively in the United States but these toys were not released for purchase.
