Netflix改編自尾田榮一郎經典漫畫的真人版影集《航海王》（ONE PIECE）第二季已正式確定檔期，將於2026年3月10日在全球同步獨家上線。隨著第一季成功打開口碑與收視，第二季不僅在故事規模與角色陣容上全面升級，也被視為整個真人版系列真正「進入主線冒險」的重要轉捩點。

第二季的官方副標題為《航海王：航向偉大航道》（One Piece: Into the Grand Line），劇情將從東方藍的尾聲正式跨入世界觀急速擴張的「偉大航道」初期。故事開端聚焦於羅格鎮，這座被稱為「開始與結束之鎮」的港口，不僅象徵海賊王哥爾・D・羅傑的時代起點，也讓魯夫首次與海軍上校斯摩格正面交鋒，為後續長期對立埋下伏筆。緊接著，草帽海賊團將挑戰顛倒山，完成進入偉大航道的關鍵儀式，正式踏上危險與未知並存的新世界航程。

隨後劇情將推進至威士忌山峰與小花園篇章，觀眾將首次接觸到祕密犯罪組織「巴洛克華克」，並看到草帽一行人逐漸被捲入更龐大的陰謀之中。這些篇章除了強化戰鬥與冒險元素，也大量著墨於角色之間的信任、價值觀衝突與團隊磨合，讓故事層次明顯加深。第二季的高潮則落在磁鼓島篇，草帽海賊團為了尋找船醫而登上冰雪王國，並在此正式迎來極具人氣、同時也是情感核心角色之一的多尼多尼・喬巴。需要特別注意的是，本季劇情將在進入阿拉巴斯坦王國之前收束，完整而重量級的「阿拉巴斯坦篇」則會留待已確定續訂的第三季完整呈現。

角色陣容方面，第二季大幅擴充世界觀中的關鍵人物。喬巴將以高度擬真的CG結合動態捕捉方式登場，由Mikaela Hoover負責配音與表演，製作團隊表示會盡力平衡可愛外型與情感表現。巴洛克華克的重要成員也將正式亮相，其中妮可・羅賓（Miss All Sunday）由Lera Abova飾演，克洛克達爾（Mr. 0）則由Joe Manganiello 詮釋，展現成熟而具壓迫感的反派魅力。薇薇公主（Miss Wednesday）由Charithra Chandran飾演，將為後續阿拉巴斯坦劇情鋪陳情感基礎；磁鼓島的重要角色古蕾娃醫生則由資深演員Katey Sagal出演，增添戲劇厚度。第一季便埋下伏筆的斯摩格上校，則由Callum Kerr飾演，預計成為草帽一行人在偉大航道初期最具代表性的海軍對手。

在製作層面上，第二季的整體規模被外界普遍認為將超越第一季，無論是場景、特效還是角色數量都大幅增加。拍攝已於南非開普敦順利完成，目前正進入大量視覺特效與後期製作階段。考量到喬巴、小花園巨人族與偉大航道特殊環境的呈現，後製工程被形容為「系列至今最具挑戰性的一季」。此外，Netflix 早在 2025 年便提前宣布續訂第三季，顯示平台對《航海王》真人版的長期規劃與高度信心。

整體而言，《航海王》第二季不只是故事篇章的自然推進，更是從冒險入門邁向宏大世界觀的關鍵一步。隨著偉大航道正式展開、巴洛克華克登場以及喬巴的加入，這一季被視為真人版能否真正站穩長壽影集之列的試金石，也讓全球粉絲對2026年春季的航海冒險充滿期待。

Netflix’s live-action adaptation of Eiichiro Oda’s classic manga ONE PIECE has officially confirmed the release date for its second season, which will premiere globally and exclusively on March 10, 2026. Following the strong reception and viewership of the first season, Season 2 significantly expands both the narrative scope and the cast, and is widely regarded as the point where the live-action series truly enters the core storyline of the original work.

The official subtitle of Season 2 is One Piece: Into the Grand Line, marking the transition from the conclusion of the East Blue saga into the early stages of the Grand Line, where the worldbuilding rapidly expands. The season begins in Loguetown, the town of beginnings and endings tied to the legacy of Gol D. Roger. Here, Luffy faces Marine Captain Smoker for the first time, setting up a long-term rivalry that will echo throughout the series. The story then moves to Reverse Mountain, where the Straw Hat Pirates officially enter the Grand Line, a pivotal milestone that symbolizes their commitment to a far more dangerous and unpredictable journey.

From there, the narrative progresses through the Whiskey Peak and Little Garden arcs, introducing viewers to the secret criminal organization Baroque Works and gradually drawing the Straw Hats into a much larger conspiracy. These arcs not only heighten the action and adventure but also deepen the emotional and thematic layers of the story, emphasizing trust, ideological clashes, and the evolving bonds within the crew. The emotional high point of the season arrives with the Drum Island arc, where the crew searches for a ship’s doctor and encounters one of the franchise’s most beloved characters, Tony Tony Chopper. It is important to note that Season 2 will conclude before the crew enters the Kingdom of Alabasta, with the full Alabasta arc reserved for the already-confirmed third season.

In terms of casting, Season 2 introduces a wide range of pivotal characters that greatly expand the series’ universe. Tony Tony Chopper will be brought to life using high-end CGI combined with motion capture, with Mikaela Hoover providing both voice work and performance. The production team has stated that special care has been taken to balance Chopper’s cuteness with emotional authenticity. Key members of Baroque Works make their debut as well: Nico Robin (Miss All Sunday) is portrayed by Lera Abova, while Crocodile (Mr. 0) is played by Joe Manganiello, delivering a mature and intimidating presence as the season’s central antagonist. Princess Vivi (Miss Wednesday) is portrayed by Charithra Chandran, laying the emotional groundwork for the Alabasta storyline to come. On Drum Island, the eccentric but crucial Dr. Kureha is played by veteran actress Katey Sagal, adding dramatic weight to the arc. Meanwhile, Captain Smoker, whose presence was foreshadowed in Season 1, is portrayed by Callum Kerr and is expected to serve as one of the Straw Hats’ most prominent Marine adversaries during their early Grand Line journey.

From a production standpoint, Season 2 is widely believed to surpass the first season in overall scale, with larger sets, more complex environments, and a significantly expanded character roster. Filming has already wrapped in Cape Town, South Africa, and the series is currently deep into post-production, with extensive visual effects work underway. Given the inclusion of Chopper, the giant warriors of Little Garden, and the unique environments of the Grand Line, the post-production process has been described as the most technically challenging the series has faced so far. Netflix’s decision to renew the show for a third season as early as 2025 further underscores the platform’s long-term confidence in the live-action ONE PIECE project.

Overall, ONE PIECE Season 2 represents far more than a simple continuation of the story. It marks a decisive shift from an introductory adventure to a fully realized epic, as the Grand Line opens up, Baroque Works enters the stage, and Chopper officially joins the crew. As such, the season is widely seen as a crucial test of whether the live-action adaptation can truly establish itself as a long-running flagship series—and it has already generated immense anticipation among fans worldwide for its 2026 release.
