Fire Stratos car transforms into Dag Fire robot. Dag Fire, Fire Jumbo, Fire Ladder and Fire Rescue combine to form Fire Dug-One (Power Dagwon).

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" form.)

A number of supporting characters and enemies across the Brave Series had designs or remolds derived from earlier and present (for the day) Generation One Takara Transformers designs, most notably those of Transformers: Zone and Transformers Battlestars: Return of Convoy (the latter never having its own animated series). The enemy "Geister" characters in Brave Exkaiser (save for their leader, Dino Geist) were actually remolds of first-generation Dinobot toys, for instance.

Toys for these robots were created in two sizes: DX ("deluxe") versions that contained more gimmicks and more complicated transformations, and STD ("standard") versions that contained fewer gimmicks and more limited transformations, but often also higher accuracy in reproducing the look of the robot from the anime series. Generally, the transformation of the robots was created by Takara, while the look of the robots was created by Kunio Okawara, legendary Sunrise mecha designer.
