Giradorus, sometimes spelled Gira Dorus, was a Kaiju from the TV series, Ultraseven. It appeared in episode 20.
A Bioweapon created by Alien Shaplay to help him in his search for the substance that made up the core of the Earth, Giradorus searched underground while Shaplay disguised himself as the Seismologist's assistant.
After Shaplay was killed by the UG, Shaplay ordered his monster to kill the other members. Giradorus arose from the surface and began to rampage with his additional weather-controlling powers until Dan transformed into Ultraseven, saving the other members underground and bringing them to the surface. Because of Giradorus's weather manipulating tusks Ultraseven found it difficult to battle him, but the hero continued to fight. After escaping a tackle Ultraseven used the Eye Slugger to decapitate Giradorus, spilling the pieces of the Earth's core from his neck.
