Duke Freed unites with Koji and the Drill Spazer to chase a Vegan saucer beast. The Vegans make an acid swamp to sink the Space Science Centre.

A young man by the name of Hiyoshi is very interested in searching for ancient evidence to prove that spacemen came to Earth in the past. He goes to look at walls in a near-by cave for ancient scripts to prove his theory, but the villagers think he is crazy. Hundreds of years ago, the Vegans had sent some of their people to Earth. There still is a metal on the wall that they used for landing, and this metal cannot be detected by the radar.

A strange meteor heads slowly towards Earth and Koji will go unilaterally and see what it's all about. After nearly getting blinded by a ray that came out of the meteor, Koji's Double Spazer begins to exit the Earth's atmosphere.

Dr. Umon's Space Science Centre is undergoing some major changes to keep up with Vega's attacks. A super computer is installed in the base, and turning it on will be the final step. The Vegans plan to get rid of the base and leave Grendizer without a place to hide.

Hikaru loses her consciousness during training and Duke Freed gets injured and his old wound gets worse. The Vegans begin their attack and Daisuke goes to the battle even though he is injured.

Dampee Makeeba organizes a party at the ranch and invites Koji and Duke Fleed. The latter has no time to eat anything because Vega attacks. Will he have the time to make it to Grendizer before the earth is ravaged? All bets are open...

Koji discovers the identity of the Duke Fleed, but has no time to ask questions because Vega attacks. Duke Fleed and Koji unite their power and push back the enemy.

Koji Kaboto tries his OVT that he made with pieces of mecano. When flying, he is attacked by the UFOs of Vega. Fortunately Duke Fleed arrives on time to save the day (but not too quickly nonetheless). Koji does not actually know that Duke Fleed is the prince of Fleed.

Moros, Duke's best friend from Freed was made to believe that Duke Freed destroyed Freed by Vega and now comes to Earth to kill Duke.

Princess Rubina, Duke Fleed's fiancé comes to Earth to tell Duke that his planet is no longer polluted but dies after being shoot by one of Vega's generals.

Gandal wants to discover the hiding place of Grendizer. So he launches a massive attack. Koji tries to confront the enemies alone, but he only succeeds to crush himself on a deserted island. Finally Duke Fleed makes it there and saves the day.

Koji, Hikaro, Goro and Bunta are taken in hostage. Actarus interrupts his siesta to free them.

Hikaro leaves for Perlepolis with Bunta. Their bus is attacked by a monster of Vega. Koji distracts the monster the time that Duke Fleed arrives (Grendizer has trouble to start up in winter).

Janus, from the fearsome Ruins' Division, attacks Grendizer that is powerless in front of the brutality and the agility of his enemy.

Blaki sets a trap to Grendizer by hiding mines in a cloud of spatial dust. Koji falls in the trap. Fortunately Duke Fleed helps him and destroys the Golgoth 8.
