Earth Demon Beast (地球魔獣, Chikyū Majū, 43-50): When Demon Beast Daitanix is killed, a piece of its filthy flesh ended up within the Earth itself and slowly evolved into a new monster form, the Earth Demon Beast. The Barban then decides to make it the new host of their castle. However, having just been born, the Earth Demon Beast was not big (though it was still a very large creature) or strong enough, so Destruction King Battobas along with Black Marketeer Biznella attempts to give it the Extreme Growth Extract eventually succeeding with the monster now fully grown but at the cost of both Battobas' and Binzella's lives.
At full size it possessed immense brute strength, could breathe fire, and was able to fire deadly bursts of energy from his claws. Having attached the castle to it, Captain Zahab confronts Gingaman. The Earth Demon Beast puts an excellent fight (defeating Combined Beast-Warrior BullTaurus after it destroyed Zahab castle), but after a hard battle is killed by the a sustained burst of fire from Super Armor Shine Gingaioh after gaining a power boost from Steel Starbeast GigaPhoenix and Steel Starbeast GigaRhinos.
