The title of legendary warrior is passed down to the young people of Ginga Forest, where humans and star beasts live in hiding, and is only granted to the brave. It began with the warriors of Ginga Forest who sealed Balban 3,000 years ago, and the current Gingaman is the 133rd generation.

The Star Beast Sword has been passed down to each generation of Gingaman as proof of their warrior status, and they are reincarnated (transformed) into Ginga with the Ginga Bracelet, a warrior's bracelet given by the star beast. Even before transforming, they can control the power of nature through Earth, and fight with physical abilities trained in preparation for battle. They are characterized by running with their hips lowered like beasts during battle.

Their introduction line is, "The legendary blade that pierces the galaxy, Star Beast Sentai Gingaman." Another characteristic is that they slam the ground when introducing themselves. Basically, five people introduce themselves, but in the final chapter and "Gingaman vs. Megaranger", six people including Hyuuga introduce themselves.
