Kugo defends the Queen Cosmos from attack by another spaceship on a muddy asteroid, but they seem evenly matched and both retire to recover. Princess Aurora wants Kugo to ask the stranger to join them on their mission rather than continue a pointless fight. Professor Kitty had told her that she would find two more companions on her journey. Kugo searches for the other fighter who meanwhile gets on board the Queen Cosmos and introduces himself as Don Hakka. Aurora convinces him to join her mission. Kugo returns and joins Hakka to deflect some dangerous asteroids. The three then depart, and later land on a watery asteroid to get water. After they land, a figure emerges from the water.

A figure emerges from the water in his space ship and attacks the Queen Cosmos. Aurora insists they talk rather than fight, and Hakka volunteers to talk to the stranger who introduces himself as Sir Djorgo. Hakka is unsuccessful, and so Kugo engages Sir Djorgo in battle. Meanwhile a large spaceship appears and releases hundreds of clam-type mutants from the army of Asari and Shijimi, intent on taking water from the asteroid. They recognise the Queen Cosmos and its mission and attempt to destroy it. Kugo breaks off his battle with Sir Djorgo to defend the Queen Cosmos. Sir Djorgo joins him to fight the mutual enemy, and the three cyborgs defeat the clam-type mutants. Sir Djorgo offers to join the mission as he calculates that no less than the three of them can succeed on the journey.

Princess Aurora and the three cyborgs in the Queen Cosmos are sucked onto a planet with a crystal palace. The queen abducts Aurora and traps her in the crystal palace. The three cyborgs cannot save her and Kugo returns to Earth where Professor Kitty gives him the Fire Ox weapon. He returns and defeats the crystal monster. Professor Kitty also sent three badges with the inscription, "Friendship is stronger than any weapons".

The Queen Cosmos encounters a meteor shower. The Ship is attacked by a hoard of pirate Space Wasps. Kugo and Hakka go out to confront them, but Kugo defeats them even before Hakka arrives because his increased weight slows him down. A Space Wasp notifies their leader Denki that they have been defeated, and he sends the Destroyer Team. His fear is that if Princess Aurora revives the Great Planet, they will revert to lowly wasps again. Meanwhile Kugo and Hakka argue about their relative strength and Kugo tells the story of how he obtained his energy polymer Astro-Pole. The Space Wasps attack again in full force and the three cyborgs go to repel them. However Kugo destroys their hive to weaken them and prevent them from attacking other space ships.

While Kugo and Hakka argue about who’s the best fighter, the Queen Cosmos receives a SOS signal from the planet Tantar in the Zenpou star system. Princess Aurora sends Kugo and Hakka to investigate what should be a dead planet. They land and investigate some ruins, but are attacked by remote controlled robots. Kugo and his ship disappear, and he is captured by the Fierce Bat in his underground lair. Hakka, disguised in a robot shell, goes to the rescue Kugo and destroys the robot control panel. When the Fierce Bat leaves to attack the Queen Cosmos, Hakka goes in pursuit and destroys his ship, with the unseen assistance of Djorgo, but they let Hakka take the credit.

A group of spider monsters attempt to implement a “shocker plan” to prevent Princess Aurora and her crew from getting to The Great King planet. They create a colourful electronic cloud that distorts their perceptions and they begin fighting each other. Only Djorgo is not affected. He realises that he has 30 seconds periods to act without being effected by the light. It’s up to him to save the others.

The Queen Cosmos travels through dark space and the crew decide to land on the planet Espérance to rest. Kugo and Djorgo go to investigate if it’s safe. They land and find the planet deserted and cities in ruins. They suspect it was caused by a large rock-like fossil monster and attack it, finally destroying it. Princess Aurora lands in the Queen Cosmos and realises that the dream planet is no longer the planet of natural beauty and hope. As she is walking, she disappears.

The three cyborgs go searching for the missing Princess Aurora. Djorgo deduces that she was teleported elsewhere. They find an installation below the surface and investigate. They encounter a mysterious figure, Ben, who asks them to kill all of the fossil monsters in exchange for freeing the princess. They agree, and attack and kill the monsters, The princess meets her captor, Princess Nova of the Espérance Kingdom. She wants to make Aurora her slave out of jealousy of her beauty, but Ben has promised her freedom in exchange for destruction of the fossil monsters and decides to free her. Princess Nova attacks the Queen Cosmos and Ben is wounded by cannon fire. She is distraught and runs to him. Ben is alive, and joins hands with Princess Nova and Princess Aurora and vows to live until Espérance is returned to its former beauty.
