This subterranean-combat Nezire builds a machine to attract a piece of a heat-guiding meteor to Tokyo in order to use its energy to destroy the city in one blow. Managing to overpower Mega Black, but losing a fragment of the meteor, Mogura Nezire falls back and later abducts Mr. Ooiwa and Mega Black. With Mega Black regaining his composure, he saves Ooiwa and fights Mogura Nezire as the others arrive and destroy Mogura Nezire's base. Mega Black then breaks Mogura Nezire's claws off and was about to kill him when Bibidebi intervenes and bites the Nezire Beast. With Mega Black piloting Galaxy Mega, Mogura Nezire is destroyed by the giant robot's Galaxy Lance.
