What Defines “Strongest” in One Piece?
Before we crown our champion, we must establish what we mean by “strongest.” In One Piece, power isn’t just about raw strength. It encompasses:
- Devil Fruit mastery and creativity
- Haki proficiency (Armament, Observation, Conqueror’s)
- Physical strength and endurance
- Strategic intelligence and battle IQ
- Feats and accomplishments
- Influence and reputation in the world
Top Contenders for the Strongest Character
Based on these criteria, several characters stand out as potential candidates for the strongest in One Piece history:
The Legends of the Past

Gol D. Roger
The Pirate King who conquered the Grand Line and found the One Piece. His strength was legendary, and he possessed the ability to hear the “Voice of All Things.”

Edward Newgate (Whitebeard)
Known as the “Strongest Man in the World,” Whitebeard possessed the Gura Gura no Mi, allowing him to create earthquakes and tsunamis at will.

Monkey D. Garp
The “Hero of the Marines” who fought Roger to a standstill. His raw physical strength and Haki mastery are unparalleled, even in old age.
The Current Yonko
The Four Emperors rule the New World with immense power and influence. Each possesses unique abilities that make them formidable forces:

Kaido
Known as the “Strongest Creature,” Kaido’s Uo Uo no Mi allows him to transform into a massive dragon. His durability is legendary, and he’s survived multiple executions.

Charlotte Linlin (Big Mom)
With the Soru Soru no Mi, Big Mom can manipulate souls, giving her terrifying abilities. Her physical strength and endurance are monstrous.

Shanks
The youngest Yonko who wields Conqueror’s Haki at an advanced level. His mere presence intimidates even the strongest warriors, and he ended the Marineford War with a single threat.

Marshall D. Teach (Blackbeard)
The only person known to wield two Devil Fruits, including the Yami Yami no Mi and Gura Gura no Mi. His unique physiology allows him to host multiple Devil Fruit powers.
The Marine Admirals
The Admirals represent the Marines’ greatest military power, each possessing incredible Devil Fruit abilities and Haki mastery:

Sakazuki (Akainu)
The Fleet Admiral with the Magu Magu no Mi, allowing him to create and control magma. His ruthlessness and determination make him a terrifying opponent.

Borsalino (Kizaru)
With the Pika Pika no Mi, Kizaru can move at the speed of light and shoot destructive lasers. His speed makes him nearly impossible to hit.
The Rising Stars
The new generation is quickly catching up to the legends, with power levels that grow exponentially:

Monkey D. Luffy
The protagonist who awakened his Devil Fruit into the Mythical Zoan Hito Hito no Mi, Model: Nika. His Gear Fifth transformation grants him cartoon-like powers that defy reality.

Roronoa Zoro
Luffy’s first mate who mastered Conqueror’s Haki and can coat his swords in it. His three-sword style and durability make him one of the strongest swordsmen.

Nico Robin
The archaeologist who awakened her Devil Fruit, allowing her to create giant body parts anywhere. Her intelligence and strategic use of her powers make her a formidable fighter.

Our Verdict
After careful analysis of all contenders, we believe that Gol D. Roger remains the strongest character in One Piece history. His accomplishments as the Pirate King, his ability to hear the Voice of All Things, and his legendary status even years after his death place him at the pinnacle. However, Monkey D. Luffy with his awakened Devil Fruit and rapidly growing power is on track to potentially surpass Roger by the end of the series.
