7 Best One Piece Rivalries That Will Define the Endgame
When it comes to building iconic rivalries, very few anime come close to One Piece. Eiichiro Oda has spent decades carefully crafting conflicts that go far beyond simple fights — each rivalry reflects clashing ideals, personal growth, and the larger struggle for power on the Grand Line. As the series moves into its final saga, these rivalries are more relevant than ever.
Here are the 7 most compelling One Piece rivalries that fans expect.
1. Roronoa Zoro vs Dracule Mihawk
This is arguably the most iconic rivalry in all of One Piece. From the moment Zoro was utterly defeated by Mihawk in East Blue, a fire was lit that has never gone out. What made that moment unforgettable was not the loss itself — it was Zoro’s refusal to quit and the genuine respect Mihawk showed him in return.
Zoro has spent the entire series closing that gap, training under Mihawk himself during the timeskip. Now, with Zoro’s power at an all-time high following the events of Wano, a final duel feels closer than ever. Oda has been building toward this for over 25 years, and when it finally happens, it will likely be the greatest sword fight in anime history.
2. Van Augur vs Usopp (God Usopp)
Two snipers, two crews, one inevitable showdown. Van Augur of the Blackbeard Pirates and Usopp of the Straw Hats are mirror images of each other in many ways — both defined by their precision, their loyalty, and their role as the long-range specialist of their respective crews.
While their full clash has already begun in the manga, the anime adaptation is something fans are eagerly waiting for. This fight is not just about accuracy — it is about pride, growth, and proving who the greatest sniper on the seas truly is.
3. Blackbeard vs Shanks
Of all the rivalries heading into the final saga, this one carries the most weight in terms of lore. Shanks’ facial scar — one of the most mysterious details introduced early in the series — was revealed to be Blackbeard’s doing, confirmed during Shanks’ conversation with Whitebeard. That single detail has been foreshadowing an inevitable clash for decades.
Both pirates now command enormous power and influence. Blackbeard has collected multiple devil fruits and built one of the strongest crews in the world, while Shanks has finally stepped onto the world stage in a major way. Their collision could genuinely shift the balance of power across the entire ocean.

4. Nico Robin vs CP-0
This rivalry is rooted in something far deeper than combat — it is about the survival of history itself. The World Government has hunted Nico Robin since she was a child, purely because she can read the Poneglyphs and uncover the truth of the Void Century. CP-0, as the government’s most elite agents, represent the greatest institutional threat to everything Robin and the Straw Hats are fighting for.
Every encounter between Robin and CP-0 is a high-stakes blend of action and espionage. As long as the Five Elders and Imu remain in power, this pursuit will not end — making Robin’s survival and the eventual revelation of the Void Century one of the most important storylines in the entire series.
5. Shanks vs Buggy
Not every rivalry needs to end in bloodshed — and this one is proof. Buggy and Shanks grew up together as apprentices on Gol D. Roger’s ship, and their contrasting personalities have been clashing ever since. Buggy’s deep resentment of Shanks’ easygoing nature and natural talent has fueled decades of one-sided bitterness that is as entertaining as it is surprisingly layered.
What makes this rivalry unique is the underlying mutual respect. Despite Buggy’s constant complaints, neither of them would truly want to destroy the other. Now that Buggy has somehow risen to the rank of Emperor, their dynamic has become even more fascinating — and funnier.
6. Monkey D. Luffy vs Koby
This is One Piece’s most philosophical rivalry. Luffy and Koby started their journeys together, with Luffy being the one who pushed Koby to stop running from his dreams. Since then, Koby has grown from a timid boy into one of the Marines’ most promising young officers — a hero of the seas in his own right.
Their ideologies, however, are fundamentally opposed. Luffy fights for freedom without rules. Koby fights for justice within a system. As both continue to grow stronger and the world moves toward its final conflict, a serious confrontation between them feels unavoidable. When it happens, it will not just be a physical battle — it will be a clash of two completely different visions for what the world should look like.
7. The World Government vs Joy Boy
(The Longest of All)
This is the oldest and most far-reaching rivalry in One Piece — one that has shaped the entire world long before the story even began. Joy Boy’s rebellion against the World Government centuries ago left a wound that has never healed, and its echoes are felt in everything from the Poneglyphs to the Void Century to the existence of the Ancient Weapons.
This is not a rivalry between two people. It is a war of ideologies — freedom versus control, truth versus erasure. With Luffy now confirmed as the inheritor of Joy Boy’s will, this ancient conflict is heading toward a resolution that promises to rewrite the history of the entire One Piece world.
