_Story_
The Daiku Maryu team had receive multiple S.O.S.'s across the Galaxy from various worlds been attack by an assailant more powerful than the Zelans, Space Tyrant Wilder and his Blood Buffalo – the last one originating 6000 light years in the Sigma Constellation, and close to the Taurus Constellation – which their systems had picked up a large object constantly traversing towards it, leading to the crew wonder who Wilder is.

On Zela, Darius now force to get outside help, orders his General to receive Space Tyrant, wanting him to destroy the Daiku Maryu with his Blood Buffalo. Later, as the General escort Blood Buffalo to Zela, the group comes under attack by a force of Alien Survivors from the Tyrant's previous attacks; Wilder takes on the fight and decimates them with his Mechanical Monster without problem. The display of strength and barbarism even shocks the often Cold Generals. The traverse of the Object is watch by the Daiku Maryu team on Earth.

Once on Zela, Darius treats his honor guest with a banquet which Wilder finds Disgusting, the Emperor force to recognize his point due to the precarious situation of his planet, which brings Earth and its boundless natural resources into their discussion – and the Daiku Maryu, wanting him to destroy it in exchange for the share of the Bounty of the Planet's resources; Wilder accepts the challenge, mocking the fact Darius can't destroy a single Earth Spacecraft and takes off with Grotestars to Earth, the Emperor vowing to strike him down after his battle with Daiku Maryu. When Arriving, Wilder sees Earth and heads to it, its arrival detected by heroes and travel to the American Southwest to deal with it.

On the American desert, Blood Buffalo emerges from the ground kills a duo of Buffalo Hunters, and find Earth nice, he decides to perhaps not to share it with Darius; at that moment, the Daiku Maryu arrives: Blood Buffalo goes on the attack first as the Daiku Maryu dashes towards it with Giant Cutter, but the Monster blocks it the move and tosses onto the ground below. Blood Buffalo then tries to skewer the Daiku Maryu, forcing Pete to fire Miracle Drills, which had no effect on the monster. The ship then dashes with Big Horns unleashed, and is locked in a grip with the Monster – even with its Engines at full power – the Daiku Maryu proves no match to the Buffalo, and Wilder just lets them go, ramming onto the side of a mountain. Blood Buffalo then rams the Daiku Maryu again and again into the air, all the way into Space – the General watch the battle from a distance and Darius interjects and orders them to mount an attack on Wilder and his Beast once its done with Daiku Maryu.

With the situation now out of control, the Big Horn is retracted, allowing for the Gaiking parts to be launched, but the Mecha proves no match to the Buffalo and it too is ram, all the way into deep space, into a section called the Sargasso Sea, a segment around the Solar System that exerts a powerful whirlpool of Ether; any ship that falls into it never comes out, countless vessels had fallen into it, creating a graveyard. Gaiking falls into it, and Daiku Maryu is shoved into by Blood Buffalo, one of its horns stabbing the ship and damage to its systems including System H, which help make the Volution Protect Mode. Darius orders Wilder to finish the Daiku Maryu, but contempt it is doomed in its predicament, travels back to Earth to Ravage it, to the anger of Darius.

Trap in the Sargasso Sea, the heroes only hopes now lie with the Volution Protect to cut through the Ether Wall, which Sakon is trying to repair, though he is able to achieve a level that would allow a Partial Volution Protect at 90% – thus requiring Gaiking's help to complete it.

The team carries out the plan with Gaiking connecting with the neck and tail making the rest; initiating Screw Escape, the Daiku Maryu begins to spin at high speed; while still be held by the Ether Wall, the heroes break free, to the horror of Darius, who warns Wilder, blaming him for not finishing the job; Blood Buffalo turns around to confront the incoming Daiku Maryu, which closes the fins on its back to make look like a Saw; Sanshiro then activates open Face as they do Screw Rotation once more as while unleashing Death Fire, which covers the Spinning Daiku Maryu, becoming the Raging Fire Wheel Cutter attack: with the Spines and the extreme heat, the rip the Buffalo, and Wilder, down half, Dispatching the Blood Buffalo and its master in an explosion.

Despite the demoralizing defeat, Darius promise to destroy the Daiku Maryu by himself. The heroes fly home after saving Earth from another threat.
