Demon Beast Fortress Ghelmadix (魔獣要塞ゲルマディック,Majū Yōsai Gerumadikusu?, Gingaman vs. Megaranger) is a blue-colored, newly named version of Daitanix II. When Daitanix II was thought to have been destroyed, it revealed itself later, leading to the theory that Daitanix II had been revived and/or healed by the Earth's energy, much like the original Daitanix and Earth Beast. He is killed by Combined Beast-Warrior BullTaurus & Super Armor Shine Gingaioh.
Ghelmadix's name is a pun on Kelmadick (ケルマディック号,Kerumadikku-go?), the ship from the movie Japan Sinks.
