Article summary:
For decades, four names made the Grand Line tremble: Whitebeard, Kaido, Big Mom, Shanks. They were the Four Emperors — the Yonko — the most powerful pirates in the world, governed by neither the Marines nor the World Government. A precarious balance maintained by mutual terror. Then the Worst Generation arrived. Within a few arcs, Kaido and Big Mom were overthrown. Whitebeard had been dead since Marineford. The balance collapsed. Today, the four Emperors are Shanks, Blackbeard, Monkey D. Luffy and — in one of the most unexpected twists in manga history — Buggy the Clown. A new era has begun. And it leads straight to the final war.
The title of Emperor is not official — it is awarded by no institution. It is the raw reality of power: those who control enough territory, crew members, and strength that no one dares attack them directly. A tacit recognition of absolute power.
To understand how the Yonko fit into the world balance alongside the Marines and the Warlords, see our guide to the Marines and the World Government. For the chronology of the arcs that witnessed their downfall, see our guide to the One Piece arcs in order.
The current Four Emperors of One Piece — Luffy, Shanks, Buggy the Clown, and Blackbeard: the most explosive lineup in the history of the saga.
The Former Emperors: the Whitebeard, Kaido, and Big Mom Era
For most of the saga, the Four Emperors formed the central pillar of the Grand Line's balance. Whitebeard was "the strongest man in the world" — his name alone was enough to protect entire islands that placed themselves under his banner. Kaido, known as "the strongest creature in the world," was considered invincible — he had survived every execution attempt by the Marines. Big Mom controlled Whole Cake Island through a blood pact with all her allies. Shanks, the only survivor of the old generation, remains the most mysterious Emperor to this day.
The downfall of Kaido and Big Mom in Wano — at the hands of Luffy, Law, and Kidd — created the greatest void in the world balance since the death of Gol D. Roger. To learn everything about the fallen Yonko, see our articles dedicated to Whitebeard.

Luffy and Buggy: the Most Unlikely New Emperors
Buggy, Shanks, Blackbeard, and Luffy — the four current Emperors form the most unstable and explosive lineup in One Piece history.
The appointment of Monkey D. Luffy as an Emperor after Wano was expected — his Gear 5 and the revelation of the Sun God Nika had electrified the entire world. His bounty reaching 3 billion Berries reflects a global realization: Luffy is no longer a dangerous unknown; he is a force of nature.
The appointment of Buggy the Clown, on the other hand, is one of Oda's most serious jokes. A former cabin boy under Roger like Shanks, Buggy accidentally built a legendary reputation — his former Impel Down followers thought he was a criminal genius. His Cross Guild organization (with Mihawk and Crocodile) places bounties on the heads of Marines, turning the world order upside down. This is not brute strength — it is influence. And in One Piece, influence is a power in its own right. To learn everything about Shanks, the most mysterious Emperor, see our dedicated article.

Blackbeard: the Emperor Who Wants to Destroy Everything
Marshall D. Teach — Blackbeard, the man who stole Whitebeard's Devil Fruit from his corpse and now possesses two Devil Fruits.
Marshall D. Teach — Blackbeard — is the most likely final antagonist of One Piece. He possesses two Devil Fruits: the Yami Yami no Mi (absolute darkness, which nullifies opponents' powers) and the Gura Gura no Mi (earthquakes, stolen from Whitebeard's corpse). He built his crew by recruiting the most dangerous prisoners from Impel Down. He killed Whitebeard. He defeated Law and Kidd, stealing their Devil Fruits. His sole stated objective: the One Piece and the title of Pirate King.
His final confrontation with Luffy is the heaviest narrative inevitability in the entire saga. Two bearers of the letter "D," two opposing philosophies — Blackbeard, who has been planning everything for decades, and Luffy, who moves on instinct. To understand why Blackbeard is the most terrifying antagonist Oda has created, see our dedicated article. And to explore Imu-sama's role in the final part, see our analysis.
