Upon arriving on Earth, Exkaiser and his team, the Kaisers, put their spirits into vehicles all over Japan to create physical bodies for their energy-based forms.

Exkaiser and his allies must unite their powers in order to fight the Geisters and prevent them from stealing Earth's artifacts.
Development.
"Brave Exkaiser" was a co-production between Sunrise and Takara, with the latter producing the toyline based on the series. Sunrise, who was assigned to animate the series, planned the show to be a solo series and will not have any spinoffs nor start a franchise. It was also aimed for kids at that time. Its premise was also based on one central theme: "Searching for One's Treasure", reflecting the value of important things that can only be understood after losing. This theme became the central point of the series's finale. While developing the mecha designs, Takara based the concept of the mechas from the "Transformers" toyline, as the concept of Alien Robots coming from space, though depicted them as Super Robots that combine both sophisticated and simple designs in their various forms, something that is later passed to the Transformers franchise in its later incarnations. In addition, the concept of a boy befriending a robot, a concept seen back in "Transformers Victory" was implemented in the series as seen in the bond between Exkaiser and Kouta.
Upon release of the anime, sales of the toys were among the highest in 1990 according to Takara, also describing it as their "best year" in sales. Though production narrowed down a bit due to the release of the "Super Famicom" in Japan in that same year with the year-end sales being slow due to a large amount of inventory of toys. Keiichi Tanaka, stated that "(In Kansai), There was no inventory left because we made adjustments by transferring between wholesalers at the end of the year." Takara foresaw the potential of the series as a franchise not as a toys franchise but as "a series with a compelling storyline and drama for older audiences", which affected its future incarnations.
