Gabura was the trump card of the Alien Shadow in their invasion of Earth. After his master's ship was downed by Ultraseven, Gabura emerged from the ship and attacked Ultraseven himself. The battle was relatively short and Ultraseven quickly finished the fight by decapitating Gabura with the Eye Slugger. However Gabura's head lived on even without its body and continued its assault on Ultraseven, sinking its jaws into Ultraseven's shoulder. After rescuing a fortuneteller who had a run in with the Alien Shadow, the fortuneteller exploited Gabura's weakness coming from the ship, and Ultraseven destroyed it with a Handmill Ray. Without the ship, Gabura's head melted into yellow slime and Ultraseven was forced to revert into Dan before the venom could kill him.
