One Piece

Monkey D. Luffy meets the Red Hair Pirates as a young boy living in East Blue, swearing becoming the next Pirate King. 10 years later, Luffy sets sail and experiences first adventures, recruiting the first members of the Straw Hat Pirates.

The season follows Monkey D. Luffy and the Straw Hat Pirates as they enter the Grand Line. After encountering the giant whale Laboon and his caretaker Crocus, they meet Princess Nefertari Vivi and become involved in the conflict against the criminal organization Baroque Works, led by the Warlord Sir Crocodile. Along the way, they also befriend the giants Dorry and Broggy on Little Garden.

Season 3 of One Piece, often called “Drum Island,” follows the Straw Hat Pirates as they search for a doctor after Nami becomes seriously ill. The crew travels to Drum Island, a winter-covered kingdom ruled by the tyrannical Wapol. While trying to save Nami, Luffy and Sanji climb a dangerous mountain to reach the only doctor available, Dr. Kureha. There, they meet Tony Tony Chopper, a shy reindeer who gained human abilities after eating a Devil Fruit and serves as Kureha’s assistant. After confronting Wapol and helping restore hope to the island, Chopper overcomes his past fears and joins the Straw Hat crew as their new doctor, marking an important emotional and strategic addition to the team.

The Straw Hats, with Kureha's assistant Tony Tony Chopper, finally arrive at Arabasta, which is on the verge of civil war. Vivi must reach the rebels and tell them the real cause behind the conflict, but Crocodile, leader of Baroque Works and one of the Seven Warlords of the Sea, will not just stand by and watch. In the end, Baroque Works, marine forces, pirates, the royal guards, and the rebel army clash in a battle that will determine the fate of the country itself.

Season 5 of One Piece is mostly made up of original filler stories, meaning they are not part of the main manga storyline but focus on side adventures of the Straw Hat crew. The season begins with the “Dreams!” arc, where each Straw Hat reflects on their personal goals and motivations, highlighting their determination to continue their journey. Next is the “Zenny Pirates” arc, in which the crew encounters an elderly moneylender named Zenny who lives on an island with his unusual group of companions. What starts as a conflict gradually turns into mutual respect as the Straw Hats learn about his past. The final arc, “Rainbow Mist,” traps Luffy and his friends inside a mysterious, time-distorting fog. There they meet children who have been separated from their families for years due to the mist’s strange effects. The crew helps them uncover the truth behind the phenomenon and find a way back home.
