Da-Garn is the leader of the Earth Brave Warriors. He can combine with the Earth Liner and Earth Fighter to form Da-Garn X, then combine with Ga-Orn to form Great Da-Garn GX.

As the leader of the Earth's guardians, Da-Garn has a courageous and valiant personality. He considers Seiji Takasugi as his commander and follows all of his commands. Da-Garn's alternate mode is a police car. He is quite agile and also has temporary flight capabilities. Within the star emblem on the left side of his chest is a dedicated compartment for Seiji Takasugi that he could stay in during combat.

Da-Garn was first awakened when Seiji's newly-given Aurin resonates with his Brave Stone stored in a nearby Buddhist temple. He then proceeded to possess Officer Tadashi Nemoto's police car parked outside the temple, transformed and defeated the UFO robot sent down by Redlone.

After the final battle with Ohboss, the Brave Warriors all went back to sleep, with Da-Garn using the last of his power to bring Seiji down back to Earth.
