Demon Beast Daitanix (魔獣ダイタニクス, Majū Daitanikusu, 1-42) was a monstrous entity of immense size and power, born on Captain Zahab's home planet. Tamed by the Balban by attaching their castle to its back, Daitanix served as their pirate ship, carrying them throughout the galaxy so the Balban could rob planet after planet of their treasures. Once a planet had been completely plundered, Daitanix would then plunge through it, devouring its core and converting the planet's life force into a special jewel that Zahab used to unnaturally extend the lives of himself and his crew. Long ago, the Balban and Daitanix arrived on Earth with the intent of making it their latest conquest but were defeated by the combined power of the Starbeasts and the first Gingamen who then sealed them beneath the ocean.
3000 years later, an earthquake broke the seal on the Balban and once more set them loose on Earth. Fortunately, Daitanix's seal remained intact, forcing the Balban to focus their actions on finding ways to revive him only to have their attempts constantly thwarted by the latest generation of Gingaman along with their old enemy Black Knight Bullblack and later Bullblack's successor Hyuuga. The Balban finally succeed in reviving Daitanix when Spectral Empress Iliess' lifeforce was infused into Daitanix to get its heart beating, and then was fully awakened when Destruction King Battobas used the corrupted warrior Degius (デギウス, Degiusu) as a conduit to channel a massive amount of energy from a passing Asteroid. When finally revived, it easily defeated Super Armor Shine Gingaioh, despite the aid of Steel Starbeast GigaRhinos and Steel Starbeast GigaPhoenix. However, its long period of inactivity had caused its body to decay and the strain of battle further accelerated the damage, forcing the Balban to abandon it before claiming a final victory over the Gingamen. It is later fought by Combined Beast-Warrior BullTaurus, armed with the Knight Axe, double-teaming GigaPhoenix and GigaRhinos, and finally killed by the Super Armor Shine Gingaioh.
