A series of earthquakes rocked the foundation of a hydroelectric dam, one after another, day and night, non-stop. There were no reported fault lines, so this supernatural phenomenon was reported to the D-Force, who instantly thought it was the work of a dinosaur. Late one afternoon, their hunch was proven correct! Ororo, a second massive gorgosaur, burst out of the ground and slowly made his way towards the dam! Using his hypnotic eye, he brainwashed a white cat named Neko, who was ordered to kill anyone who tried to interfere. Soon, the D-Force deployed Aizenborg 1 and 2, and the fight was on! Ororo shrugged off their laser and missile attacks, making the war seem futile. It wasn't until Ai and Zen combined and turned the Aizenborg 1 into the Super Aizenborg did Ororo pay them any attention. After almost getting grounded by the beast's terrible flame breath, the warship flew by the monster several times, confusing him and causing him to fall on his back.
