One Piece: Why the Marine Admirals Must Be Replaced in the Final Saga
A World in Turmoil and Power on the Brink of Transformation
New Marine Admirals One Piece: The Future of Justice
The world of One Piece has reached its most turbulent era. With the final saga now unfolding, every major faction—pirates, revolutionaries, and government forces—is making unpredictable moves across a global chessboard ready to collapse. Even the Marines, one of the Three Great Powers that shaped the balance of the seas, can no longer maintain their old order.
The coming great war will redefine everything. Long-standing symbols of authority will crumble, new leaders will emerge, and the justice upheld by the Marines will evolve into something entirely different. As the world edges closer to an irreversible shift, it becomes increasingly clear: the era of the current Admirals is drawing to an end, and a new generation must rise to lead.
Smoker: The Logical Successor to Akainu
At the center of the Marine hierarchy stands Sakazuki—better known as Akainu—the iron-fisted Fleet Admiral who embodies an unforgiving, absolute form of justice. After his brutal victory over Aokiji on Punk Hazard, Akainu gained the power to reshape the Marines according to his own ideology. His rule is harsh, aggressive, and uncompromising, often blurring the line between justice and tyranny.
But the final saga signals the beginning of his downfall.
Akainu faces a growing list of consequences for the choices he made throughout his career. From authorizing mass destruction to pursuing innocent lives in the name of “justice,” his legacy is soaked in blood and bitterness. His most infamous act—the death of Portgas D. Ace—remains a wound that the narrative has not yet fully healed. As One Piece approaches its climax, the story is setting the stage for Akainu’s reckoning, likely at the hands of Luffy or Sabo, tying back to the tragedy of Marineford.
When Akainu eventually falls, the Marines will need a leader who represents a very different ideal. That is where Smoker steps in.
Throughout the series, Smoker has demonstrated a rare combination of independence, integrity, and fairness. He acts according to conscience, not blind obedience. Unlike Akainu, he understands nuance and questions decisions that conflict with moral principles. His approach to justice is humane, flexible, and rooted in genuine concern for the innocent.
These qualities make Smoker the strongest candidate to rebuild the Marines in a post-Imu world—one where justice must be fair, not authoritarian.
The Rise of a New Marine Generation: Koby, Tashigi, and Prince Grus
The changes ahead will not stop at the Fleet Admiral’s position. The current Admirals—Fujitora, Kizaru, and Ryokugyu—stand at a crossroads. Whether they fall in battle, retire, or shift roles, their time as the uncontested enforcers of Marine power is nearing its end. The world they helped maintain is crumbling, and the future demands new faces who truly understand the evolving concept of justice.
Among the most promising candidates for future Admiral positions are Koby, Tashigi, and Prince Grus, with Helmeppo also standing as an unexpected but possible contender. These rising stars represent the direction Oda intends for the Marines: a force not built to crush opposition but to protect the innocent and uphold fairness.
Why Koby Stands Out
Koby embodies the heart of the new Marine vision. Once a timid cabin boy, he has grown into a courageous officer driven by empathy, determination, and a dream of a world free from corruption. His sense of justice rejects fear and oppression, making him one of the purest examples of Marine ideals.
The final saga will likely push Koby to new heights, both in strength and moral influence. With his current involvement in major events—particularly those involving the Revolutionary Army and the Yonko—he is positioned to play a defining role in shaping the new era.
Tashigi and Grus: The Future of Marine Integrity
Tashigi has long symbolized compassion and dedication. Her unwavering commitment to protecting civilians and her desire to end the circulation of dangerous swords align perfectly with a reformed Marine structure.
Prince Grus, on the other hand, represents strategic brilliance and combat potential. His unique Devil Fruit abilities and growing leadership presence make him a strong candidate for high-ranking command.
Though none of these rising officers currently match the raw power of the Admirals, Oda’s final saga promises intense growth, new alliances, and possibly undiscovered abilities that will elevate them to Admiral-level strength.
Rebuilding the Marines After the Great War
With the fall of Imu and the collapse of the World Government looming, the biggest question is no longer if the Marines will change, but how. Despite the chaos that surrounds them, the Marine organization will not be destroyed. Instead, it will be reshaped—reborn to fit the new world that emerges after the downfall of the corrupt Celestial Dragon regime.
A restructured Marine force will focus on protection, not oppression. Its purpose will be to safeguard peace and uphold lawful order without serving as a tool for tyranny. This transformation will require more than new leadership; it will require new philosophy, new foundations, and new alliances.
Figures like Monkey D. Dragon, Sabo, or leaders from the Revolutionary Army may even help dismantle the old systems and construct a just, unified force—one that aligns with the values of equality, transparency, and freedom. The legacy of Sengoku and Garp, once overshadowed by political corruption, may finally find fulfillment in this renewed Marine order.
In this rebirth, the Marines could become a symbol of true justice—an institution that protects the world instead of controlling it.
A New Era for Global Justice
The rebirth of the Marine Admirals will be one of the most defining turning points in One Piece’s ending. As major revelations reshape the world and long-held secrets come to light, the need for a force grounded in genuine justice becomes undeniable.
Fans eagerly await the global shift that Oda has been building toward for decades: a world where justice is not dictated by the Celestial Dragons but shaped by individuals who fight for fairness, compassion, and freedom.
With One Piece returning after a short break, Chapter 1166 is set to release on November 23, 2025, on Manga Plus—including availability in English for readers worldwide. As the story races toward its conclusion, the rise of new Marine Admirals marks the beginning of a new era—one built not on fear, but on hope.
