All of the main hero robots' mechanical (or "mecha") designs in the Brave series were those of prolific Sunrise mechanical designer Kunio Okawara. In most of the Brave series, there is a main hero robot (usually the most or second-most expensive toy in the line), backed up by one or two support combiner teams and later receiving one or two combiner partners, upgrading the hero to more powerful forms. (The most or second-most powerful form of the hero robot is usually known as its "Great," "Dai," or "Super" form.)
