One Piece is home to some of the strongest characters in the history of the anime industry. And not all of them belong to the Straw Hat Pirates. This list is for the legends that made a name for themselves on their own, without the Straw Hat label.
The Dark King
When you are appointed as the right hand man of the most infamous Pirate to have ever walked the Earth, you have to be taken seriously. Silvers Rayleigh was once the right hand man of the legendary Pirate Gol D Roger. He is a master of three forms of Haki – Armament, Observer and Conqueror. Silvers Rayleigh once fought the might Borsalino, otherwise known as Kizaru, while he was already of an age some would say to be too old to enter a fight. He has no devil fruit powers. Silvers Rayleigh got the moniker of The Dark King because of his inhuman levels of Stamina. He once swam from Sabody and another location known as Amazon Lily on his own. Silvers Rayleigh is one of the strongest characters ever. He could have scored higher if not for his advanced age.
Law is arguably one of the most famous Pirates in One Piece that is not a member of the Straw Hats. Trafalgar Law was trained under the tutelage of Doflamingo, who is himself a legendary fighter. Doflamingo made Trafalgar Law into a fighter who could stand as equals against even the Yonkos. After Trafalgar ate the Ope Ope no Mi devil fruit, his powers increased further. Trafalgar Law gained the power to create a room where he could control and manipulate anything he laid his hands on. Using this power, Trafalgar Law started stole hearts and manipulated people with his new powers.
Blackbeard is a very infamous pirate lord within the One Piece Universe. He also has the distinction of having eaten two devil fruits. Black Beard originally had the power to create darkness after he ate the first devil fruit. He could use it to create black hole like constructs that can suck turn everything around it pitch black. After joining forces with White Beard, Black Beard also ate the Gura Gura no Mi. The second devil fruit gives him the power to create massive earthquakes. When Blackbeard uses both of his devil fruit powers in conjunction, all hell breaks loose!
Akainu aka Sakazuki is the Fleet Admiral of the Marines. Some might say Blackbeard is more powerful than him. But we beg to differ. He is literally the one that sits atop the Naval Fleet of the World Government. Apart from that, Akainu also has a devil fruit power. His power allows him to turn his entire body into magma. Akainu has fought White Beard, one of the strongest Pirates ever and lived to tell the tale. With the power of the entire Marine Fleet under his control, he is one of the most powerful characters in One Piece.
Monkey D Dragon
Monkey D Dragon is the father of Monkey D Luffy, the leader of the Straw Hat Pirates and the Protagonist of One Piece. He likes to lead a path of revolution. Called Dragon the Revolutionary by the World Government, Dragon is the most wanted man on their list. There are many theories on what his devil fruit powers could be. He has the power to create storms, control lightning and generate powerful gusts of wind. Some say he ate a mythical Zoan fruit that allows him to turn into an Eastern Dragon, a creature that can control the weather.
If you had thought that Smoothie and Katakuri were powerful fighters, Big Mom is literally their mom in a fight. She has a rock hard skin that is very easy to crack unless you use some potent Haki. She is a member of the Yonko which automatically makes her one of the most elite captains in the world. Big Mom also has Devil Fruit ability. She has the ability to interact with souls and steal people’s life forces. Big Mom can use this power to take away someone’s life force and give it to someone or something else.
Kaido of the Beasts
The name would have been a giveaway. Kaido of the Beasts is the leader of the Beast Pirates and one of the strongest members of the Yonko in terms of raw brute strength. Kaido never shies away from a challenge, always ready to prove how strong he is. He once sank multiple prison ships with his bare hands. His aggressive attitude sometimes leads him to picking fights with the other Yonko. His durability is also extremely high and he is almost invulnerable to injury. Kaido is one tough cookie.
Shanks was introduced to the One Piece universe during the East Blue saga. Shanks may have had very little screen time but he is inhumanly strong. It is claimed that even though the guy does not have an arm, he has never lost any of his power due to that handicap. Shanks was a member of Gol D Roger’s crew. He has had a lot of experience that has toughened him up and made him into the legend he is today. He also possesses the ability of Haoshoku Haki, a very rare ability that grants him the ability to exert his willpower on others.
White Beard has been officially regarded as the Strongest Man in the World. He is recognised both by the Pirates and by the Marines as a walking weapon of mass destruction. His Devil Fruit Power grants him the ability to destroy the whole planet if he wishes to. White Beard’s true potential as a warrior was shown during the Summit Wars arc. He fought multiple Admirals and even had his entire body covered in hot lava. White Beard later died and was buried alongside Portgas D ace, his son.
Monkey D Garp
This guy can literally throw a cannonball with his own hands with similar force like that of a canon!! It was a surprise to have discovered that someone from Luffy’s lineage was in the Marines. Monkey D Garp has legendary powers of Haki. He is known as the Hero of the Marines. Monkey D Garp was the one who caught the Pirate King Gol D Roger.
Golden Lion Shiki
Golden Lion Shiki was a legendary pirate and the strongest competitor of Gol D Roger. He made an appearance in the tenth One Piece movie. Shiki was termed a living legend during his prime, able to fight the likes of Garp, White Beard and Roger to a standstill. Shiki had a huge tolerance to pain. He once amputated his own legs to escape from Level 6 of Impel Down, the first known prisoner to have ever achieved this feat. His greatest strength was his swordsmanship. He once slaughtered an entire army of Marines with his dual swords Oto and Kogarashi before he was captured by Garp and Sengoku.
