The Brave of Gold Goldran (黄金勇者ゴルドラン, Ōgon Yūsha Gorudoran) is a Japanese anime television series begun in 1995, created by Takara and Sunrise under the direction of Shinji Takamatsu, and was the sixth in the Yūsha/Brave metaseries.
Goldran follows the adventures of three young boys who are tasked with finding alien robot fighters, or Braves, that are sleeping in the form of crystals.
The entire show is extremely focused on comedy and silliness almost to the exclusion of much in the way of storytelling, although the series does develop some running plot lines towards its end.
They bring back Dran, the golden robot, a brave who slept within a Power Stone and become his master.
If the Braves are defeated or their masters are killed they will revert into Power Stones, indestructible gems that can only reactivate them by reciting an ancient incantation.
