In the past, the 34 Super Sentai defended the Earth against Space Empire Zangyakku. The soldiers of legend lost their powers during this battle, but through their sacrifice, Zangyakku was able to be repelled from the Earth. Several years later, we meet a group of young pirates who travel aboard the ship, GoukaiGalleon. They are in search of the "Uchuu Saidai no Takara" (Greatest Treasure in the Universe). They head towards Earth, where it is said the Greatest Treasure rests.

The Space Empire Zangyakku begins their second invasion of Earth. They set up their fleet headquarters between the Earth and the Moon. On the other hand, Marvelous and co. are told by Navi to "start their treasure hunt on Earth by finding people with black clothes." However, because of Navi's rough navigation, they are having a bit of trouble doing that. Coincidentally, in front of them appears a man.

GoukaiGalleon has a midair collision with a Zangyakku battleship, sending the battleship into a firey crash. GoukaiGalleon is forced to make an emergency landing as well. Before they know it, the team is under the attack of Kodou Taichou Salamandam, and the five are blown off by an eruption he causes. When they come to, they once again meet the mystery man, but who is he really?

The Gokaigers had achieved the Great Power of the Magiranger. Using the Magiranger Keys in the cockpit, the Rangers activated MagiDragon. Action Commander Zodomas, a sword specialist, appears and begins destroying the city. Joe and Ahim are out shopping when Zodomas attacks, and have to start fighting with Marvelous, Don and Luka. Joe is made a fool of by Zodomas' sword techniques, and after the battle he decides he needs to go this one alone, and leaves Gokai Galleon. Ahim is worried about him, and tries to convince him they need to fight as a team. Can Joe really defeat Zodomas on his own? Grasp this battle in your hands! It's not something you want to miss!

Navi, using its Otakara Navigate ability to go to the police because they will tell them something good. Later on, Marvelous finds one and he is no other than Space Police's Earthshine Chief, Doggie Kruger! And the problem is, he is interested in arresting the Gokaigers! The Zangyack later appears and Marvelous can't do a thing because he is in handcuffs!

Luka sees a jewel she desperately wants, but to her displeasure a little girl buys it before she can get her hands on it. Suddenly, the girl's father approaches Luka. He'll give her the jewel if she comes and works in his house, and so she is invited. Within the house there seems to be a treasure, as the Zangyack are targeting it as well. For the sake of doing some recon, and protecting a potential treasure, and also for selfish reasons, Luka decides to take the job. But can Luka really do said job? And what is the treasure the Zangyack are looking for?

Navi asks them to look for a "Tiger Boy for Great Wisdom" and so, they started heading out to search for zoos. However, the Kung Fu Specialist Action Commander, Pachamac XIII appears and begins destroying the city. In the battle, Doc and Ahim tried to take on the Commander and the lost which cause them to feel down for themselves. By chance, the came into a group that teaches Kenpo Lessons for kids. Teaching the kids is a young man and the two started their Kenpo training. Will Doc and Ahim defeat this Kung Fu Specialist? And who is this man?

The Zangyack Empire sends the Sneak Brothers to spy on the Gokaigers.

In a race to find the floating island before the Zangyack forces do, the Gokai Galleon crew instead finds a veterinarian.

Joe and Luka infiltrate the Green Fleet, the Zangyack Empire's special forces, to learn more about their Gigarollium Cannon.

With Navi's next clue being "Sa-mu-r-aa-i", the Gokai Galleon crew seeks out a kendo club until they are approached by a girl who claims to be the samurai known as Shinken Red. Joe begins training with her to face off against his old comrade Barizorg.

Joe goes off to face Barizorg alone in an attempt to make him remember his past as Kaoru assists the Gokaigers in their fight against the Zangyack Empire.

Ahim is kidnapped after going out into town and held hostage. Captain Marvelous leads the other Gokaigers to save her, claiming that he does not want to pay the ransom.

Aboard the Gokai Galleon, the crew is taking a nap when Navi's dream triggers a new clue for the pirates, telling them to learn traffic laws. Meanwhile, while reviewing Zaggai's activities aboard the Gigant Horse, Insarn falls in love with a man that the Action Commander crossed paths with: Kyousuke Jinnai (Red Racer).

Don shows his shipmates that the Gokaigers' bounties have skyrocketed to nearly the same level of the Red Pirates. Showing no interest in the news, Captain Marvelous tells Navi to foretell their next course; the robot parrot, however, sees danger coming their way. Meanwhile, a red Zangyack ship arrives to the Earth with Oiles Gil learning that it is captained by a privateer under the Zangyack Empire. While cautiously exploring in a town, the Gokaigers meet the privateer, who Captain Marvelous identifies as Basco ta Jolokia. He announces that he has also come for the Greatest Treasure in the Universe.

Captain Marvelous must figure out a way to save his crew members from Basco ta Jolokia without paying the ransom of all of the Ranger Keys. The crew must fight the joined forces of Go-onSilver, Go-onGold, GoseiKnight, KibaRanger, ShinkenGold, MagiShine, MegaSilver, GaoSilver, AbareKiller and BoukenSilver.

The Gokaigers head out to find this man, but in the end, they couldn't find anything at all. Suddenly, a young man shows up saying that he knows what they are looking for!

The new warrior, GokaiSilver, just suddenly appeared with 3 great powers and no one seems to know what they do. This young man really wants to join the Gokaigers, although Marvelous will only let him join on one condition.

The new warrior, GokaiSilver, just suddenly appeared with 3 great powers and no one seems to know what they do. This young man really wants to join the Gokaigers, although Marvelous will only let him join on one condition.

The next of Navi's clues leads the Gokaigers into the Ginga Forest, home of the Gingamen, and into another clash with Basco ta Jolokia. Elsewhere, Gai encounters Hyuuga who demands the Gokai Cellular from him

The Gokaigers must help Satoru Akashi search for a Precious. However, both the Zangyack Empire and a revived Ryuuwon get in their way

Gai and Joe team up to help a young boy named Shota fulfill a friend's wish, while protecting him from Action Commander Stargull.

When Navi's Treasure Navigate hints mentions an "act of mercy", the Gokai Galleon Crew proceeds to help people out. But as Basco attempts to beat their shipmates in obtaining a Sentai team's greater power, Luka and Ahim cross paths with an EMT who is more than she appears.

While getting some takoyaki, the Gokai Galleon crew once more cross paths with the Action Commander Jealousto, who after losing face to Insarn has been taken in as a "pet" by the takoyaki stand owner.

The Zangyack Empire calls upon the Space-Ninjas Satarakura Jr. and Sandaaru Jr. to take on the Gokaigers. As the two take Captain Marvelous, Joe, and Luka on, the battle is witnessed by a trio of mysterious ninjas.
