Doll Geist commanded forces for the Dragon Empire, dedicated to reviving the dark god Jashin Drago. This officer operated between episodes 29 and 41, serving directly under Empress Zara. Geist led specialized Geist Soldiers, who utilized human disguises and wielded laser rifles, mouth laser guns, and hand blades.

Significant combat abilities defined Doll Geist: flight, deployment of bat probes for reconnaissance or attack, and a bladed shield mounted on the left arm. Sharp claws extended from both arms for close combat, complemented by palm-mounted machine guns for ranged engagements. Launchable arms generated defensive or offensive black energy barriers. Further weaponry included missiles fired from the right shoulder and a claymore sword. Doll Geist operated from the flying fortress Metalhead, which housed squads of soldier metal knights.

The character also appeared in the crossover video game *Super Robot Wars NEO*.
