One Piece Final War Side-Switches and tournament

The Final War in One Piece is shaping up to be the most seismic conflict in manga history. Allegiances forged over decades are cracking, and fans worldwide are debating which characters will cross the line. At Tournament Click, we combine that passion for storytelling with the tools that bring fan communities together — from prediction brackets to full-scale esports tournaments built around beloved franchises. Let's break down the characters most likely to change sides, and explore how organized community events keep this excitement alive.

Why Allegiance Shifts Define One Piece's Endgame

Eiichiro Oda has spent over 25 years constructing a world where loyalty is never black and white. Marines who question justice, pirates who protect civilians, and World Government agents who harbor doubt — these contradictions have always been One Piece's greatest strength. In 2025, as the Final War arc accelerates, character motivations are being stress-tested like never before.

When a major character switches sides, it doesn't just change the battlefield — it recontextualizes everything that came before. Fans dissect every panel, every flashback, every throwaway line of dialogue. This level of engagement is exactly why fan communities organize prediction events, debate tournaments, and character-ranking contests that require reliable tournament software to run smoothly at scale.

Monkey D. Garp and the Weight of Family

Garp has spent his entire career walking the razor's edge between duty and love. His grandson Luffy is the man who will challenge the World Government itself, and Garp's own son Dragon leads the Revolutionary Army. The idea that Garp remains a passive bystander in the Final War strains credibility to its breaking point.

Many fans believe Garp will ultimately abandon the Marines — not out of ideology, but out of blood. His arc has always been about the cost of choosing duty over family. A defection from the Marines would be one of the most emotionally devastating and narratively satisfying moments in the entire series. On Tournament Click, fan polls consistently rank Garp as the single most anticipated side-switch of the Final War.

Kuzan (Aokiji) and His Double Life

Kuzan's departure from the Marines and subsequent alignment with Blackbeard has never felt like a genuine ideological conversion. His actions have been too measured, too deliberate, and too protective of certain individuals for him to be a true villain. The prevailing theory — that he is a deep-cover agent working against Blackbeard from within — gains more traction with every chapter.

If Kuzan reveals himself as an ally of the Straw Hats or the Revolutionary Army at a critical moment, it would rank among Oda's greatest long-game reveals. Community bracket events on platforms like Tournament Click regularly feature Kuzan in "most likely to betray Blackbeard" prediction contests, drawing thousands of participants who want to put their reading of the story to the test.

Jewelry Bonney and the Kuma Connection

Bonney's entire motivation has been reframed by the revelation of her father's fate. Kuma's sacrifice and the truth about the Pacifistas have transformed her from a minor Supernova into one of the most emotionally charged characters in the series. She has every reason to fight against the World Government, but her path to doing so may require unexpected alliances.

Bonney's age-manipulation Devil Fruit gives her enormous tactical value in any large-scale conflict. Whether she ends up fighting alongside Luffy's coalition or carving her own path, she is unlikely to remain in any fixed camp for long. For fans running esports tournaments centered on One Piece character rankings, Bonney is consistently one of the most debated entries in the bracket.

Crocodile and the CROSS GUILD Wildcard

Crocodile is perhaps the most unpredictable figure heading into the Final War. His CROSS GUILD organization — which places bounties on Marines — suggests an agenda that operates entirely outside the traditional pirate-versus-government binary. His past connection to Whitebeard, his rumored history with Imu, and his general disdain for idealism make him a geopolitical wildcard of the highest order.

The question isn't whether Crocodile will betray someone — it's who he will betray and when. Fans using a tournament platform to organize character prediction leagues find Crocodile endlessly fascinating precisely because his motivations are so opaque. On Tournament Click, he regularly tops lists of "characters most likely to surprise everyone" in community voting events.

Smoker, Tashigi, and the Marines Who Question Justice

Not every potential side-switch belongs to a single iconic character. Smoker and Tashigi represent a broader class of Marines who have witnessed the World Government's corruption firsthand and have not been able to look away. Their continued service feels increasingly untenable as the Final War draws closer and the true nature of the Void Century is revealed.

If the World Government's crimes become undeniable on a global stage, Marines like Smoker and Tashigi face a binary choice: comply or defect. Their defection would carry enormous symbolic weight, signaling that even the institutions of order have recognized the rot at the top. Fan communities on Tournament Click use a bracket maker to simulate these faction outcomes, creating interactive prediction games that mirror the tension Oda builds chapter by chapter.

Conclusion

The Final War of One Piece is not just a battle of power — it is a battle of conscience, loyalty, and identity, and the characters most likely to change sides are those whose inner conflicts Oda has been developing for years. From Garp's family-versus-duty crisis to Kuzan's suspected double life, from Bonney's grief-fueled mission to Crocodile's inscrutable agenda, and from Smoker's moral fatigue to the broader upheaval within the Marines, 2025 is shaping up to be the year One Piece fans' deepest theories are finally tested. Tournament Click is the destination for fan communities who want to celebrate, debate, and compete around these story moments — offering the tools and the platform to turn passion into organized, memorable events.
