Gaiking (English Subtitled)

Daiya Tsuwabuki is a boy in junior high who is known as the town liar. He claims that five years ago, he was saved by a large mechanical dragon when he and his father were attacked at sea by mechanical beasts.

Daiya meets the crew of Daiku-Maryu, which includes Lulu, Gaiking's supporter; Captain Garis; Vice Captain Rosa; Shizuka and Daimon in charge of the engine room; and Puria, the pilot of Stinger and the ace fighter of Daiku-Maryu.

Daiya learns that for their fight against the Darius Army, they have to go to the other world at the core of the earth, and Captain Garis gives Daiya some time to go say goodbye to his mother.

In order to return to Darius, Daiku-Maryu must go through Death Cross Point and mend the subspace in order to prevent the enemy from going to the surface.

Daiku-Maryu arrives in Darius and goes to a regional city called Paltegona to stock up on food and supplies. Captain Garis orders Rosa to take Daiya and Puria into town with her in order to give them an opportunity to start getting along.

Captain Garis temporarily assigns Daiya to five sections on the ship to decide which section he will join permanently. On the first day of the three-day trial, Daiya has a lot of trouble with the tasks of each section, especially when he has to run around Daiku-Maryu running errands for his bosses.

Daiku-Maryu docks at a tropical island where the crewmembers enjoy some beach time. Then from the other side of the island, they hear the sound of wild Demon Beasts, which are indigenous Demon Beasts that have not yet been made evil by the Darius Army.

On their way to their fort in Ohmazan, Daiku-Maryu takes a break in the Kanalups Mountains. Puria, who gets into a foul mood watching Daiya and Lulu having a great time, decides to play a prank on Daiya and puts Pelps, mosquito-like insects of Darius, into his tent that night.

One day on their way to the Ohmazan fort, Daiku-Maryu is attacked by a giant turtle beast, Domega. During the battle, Daiya and Lee try to combine Gaiking and Serpent to become Buster Gaiking, but Lee fails in the attempt.

As Daiku-Maryu approaches the dark continent of Arkholand where the Darius Army headquarters is located, Lulu starts having nightmares about her childhood and the black flame.

One day, Grotecter warships of Northern General Noza fly past Daiku-Maryu. They are on their way to create another Death Cross Point, the hole that connects to the world above the surface.

While Grotecter warships are forming Death Cross Point, Noza challenges Daiya to another duel. Daiya goes against Garis's order and accepts, even though he is daunted by Noza's strength.

After the battle with Noza, the captain and Daiya fall ill, and Daiku-Maryu, as well as Stinger and Serpent, are badly damaged. Captain makes Lulu command the ship in his absence, and reveals his identity to Daiya.

After the battle with Noza, Daiku-Maryu and Gaiking get repaired in a new fort built by rebel forces in an abandoned desert city.

During a battle in the air, a civilian airplane asks Daiku-Maryu for help, and Lulu agrees to let him come onboard. The pilot, a Darius man named Jan, demands to be taken to the surface world and tries unsuccessfully to hijack Daiku-Maryu.

One day, Lee goes on a recon mission and saves Vestarnu, who is being attacked by droid soldiers at Proist's secret quarry. She gets gunpowder in her eyes and becomes temporarily blinded.

Daiku-Maryu arrives in the lawless city of Zangyle. Captain Garis tells Rosa to oversee the ship while he goes into town.

Dick attacks Gaiking to get to the enemy, and while the enemy falters, Gaiking counterattacks. Although they managed to get through the battle, everybody is furious at Dick for his dangerous tactic.

Powerless against the enhanced Steel Beast, Stinger, Serpent, and Killjaguar retreat to Daiku-Maryu for the time being, but they learn that Proist ordered a public execution for Gaiking.

One day on a deserted island, Garis proposes a race to go find Windarium, a mineral ore that can counterattack Darius's ice beam. The winner will become the Daiku-Maryu captain for a day, and ten crewmembers decide to participate in the race.

Lulu starts reading people's fortunes when one day, she predicts that Bry, the rebel fighter and Daiku-Maryu supporter, will reunite with someone special. Meanwhile, Daiya gets jealous watching her read fortunes for other people.

One day, Yanma, Haccho, and Booby, in an attempt to prove their usefulness, force themselves onto Gaiking with Daiya. But Gaiking gets captured by the enemy, and Daiya and the trio are taken back to the enemy warship.

One day, Shizuka looks frantically for Dr. Sakon, but he is nowhere on the ship. Shizuka becomes furious and takes off on Stinger to go find him.

The Daiku-Maryu crewmembers start seeing pink hippos everywhere on the ship. Dr. Franklin informs them that they are hallucinations from Limitation Syndrome, which occurs when people feel stressed out.

The Daiku-Maryu idol contest enters the final round in which the candidates become an idol for the deciding popularity vote. They each make a performance that will attract the crew's attention.
