10 – THE REMNANTS OF THE ROGER PIRATES
The Roger Pirates were the crew of the late Pirate King, Gol D. Roger, and were the only crew to ever reach Laugh Tale, the end of the New World in the Grand Line.
The things they did were part of legends. They made it as far as Skypiea and the end of the Grand Line, Laugh Tale, on their ship the Oro Jackson.
Even though the crew disbanded, the Marine would never allow the crew to be forgotten. If a crew member is encountered, the Marines cannot simply let them go. Similarly, Portgas D. Ace, being the son of Roger, is not spared from this prejudiced hunt.
9 – KOZUKI MOMONOSUKE
Kozuki Momonosuke is an inhabitant of Wano Country and the son of the late daimyo of Kuri and patriarch of the Kozuki Family, Kozuki Oden.
He has the ability to communicate with the giant elephant Zunisha, being capable of seeing through its eyes and giving it orders, which is the only way it can do anything but walk. Should Momonosuke order it to attack, he is in command of a powerful weapon capable of wiping out fleets in a single blow. Like his father, Momonosuke also has the ability to hear the “Voice of All Things”.
8 – NICO ROBIN
Nico Robin is the only person alive who can read the language written on poneglyph tablets, which contain records of ancient history; this was the true reason why her first bounty was so high, despite being issued when she was only 8 years old.
7 – SHIRAOSHI
Princess Shirahoshi is the current form of Poseidon, one of the three Ancient Weapons capable of mass destruction.
Poseidon was a Mermaid Princess who lived in the Void Century that had the power to talk to Sea Kings, enormous sea creatures capable of mass destruction. As stated in a conversation between Neptune and Robin, Shiraoshi has now inherited the title “Poseidon”.
6 – BIG MOM
Big Mom is a born monster who was first issued a bounty at the age of six, making her the youngest known individual to ever have a bounty placed on their head.
Decades ago before the formation of her own crew, Big Mom was part of the legendary Rocks Pirates.
Charlotte Linlin has a Road Poneglyph that can, with all four Road Poneglyphs deciphered, lead to Raftel’s location.
As we know, the possibility of two or more of the Yonko forming an alliance is enough of a threat to cause the World Government to panic, as seen when it unsuccessfully attempted to prevent a meeting between Shanks and Whitebeard.
Right now Big Mom has just formed an alliance with Kaido to conquer the world. This makes Big Mom an even greater danger to the World Government.
5 – KAIDO
Kaido is the “Strongest Creature in the World”. Decades ago before the formation of his own crew, Kaido was part of the legendary Rocks Pirates as an apprentice.
Kaido has gained the reputation of being unable to die. He has been caught and tortured 18 times, and people as powerful as the Marines and other Yonko have attempted to execute him 40 times only to fail as Kaido survived every single attempt because every single execution weapon broke when being used on him. Most notably, Kaido has jumped from 10,000 meters from the sky onto the ground, creating a massive shockwave strong enough to sink a large ship nearby, and emerged only with a headache; it has even become a hobby for him to attempt suicide, only for it to fail.
Kaido recently has entered into an alliance with fellow Yonko Big Mom and her crew, the Big Mom Pirates. Like Big Mom, Kaido possesses a Road Poneglyph too.
4 – SHANKS
Shanks is the youngest of the Yonko and his crew is the most well-balanced and impenetrable crew among the four Yonko crews!
Shanks is currently the most capable person who could find the One Piece. He’s a former member of the Roger Pirates and knows the truths about the Void Century, the meaning of D., and the Ancient Weapons, although he has not been at Laugh Tale.
One of Shanks’ greatest attributes is his leadership and charisma, having managed to earn the absolute trust and loyalty of the most talented and capable individuals from the four seas and Grand Line all noted for having particularly high bounties and recruited them into his crew.
3 – MONKEY D. DRAGON & REVOLUTIONARY ARMY
Monkey D. Dragon is the infamous leader of the Revolutionary Army, a powerful military organization whose objective is to fight against the World Government’s rule over the world. He is the World Government’s greatest enemy, and is the most dangerous man in the world.
As the leader of the Revolutionaries, he has full control of the organization. There have been some hints that Dragon is extremely powerful, since the World Government has dubbed him as the “World’s Most Wanted Man”.
2 – BLACKBEARD
Blackbeard is the new power that replaced Whitebeard and he’s still growing.
He has become the first and, so far, only known person to wield the powers of two Devil Fruits at the same time. Through unknown means, he acquired the extremely destructive powers of the Gura Gura no Mi from the dead body of Whitebeard and is now able to create earthquakes like his old captain.
Blackbeard is the one who carry the Will of Rocks D. Xebec, who was considered to be the most formidable rival of the Pirate King Gol D. Roger and such a danger for the World Government that his name has been erased from history. Xebec’s defeat was also what caused Garp to become a legend and to be known as the Hero of the Marines, showing how much of a threat he was considered by the World Government.
Shanks himself seems to know the potential danger Blackbeard represents is greater than that of anyone else.
1 – MONKEY D. LUFFY & STRAW HAT PIRATES
“It’s not his powers or techniques. He possesses some quality that makes people want to help him. And on these waters, that is the most formidable power of all!” – Dracule Mihawk Recognizes Luffy’s True Power
Despite having a small number of members, the Straw Hats are a very powerful crew. Their captain Monkey D. Luffy has continuously defeated people who are renowned for their incredible strength such as Crocodile, Gekko Moriah, Donquixote Doflamingo, the highly feared tyrant Enel from Skypiea and Rob Lucci of the CP9 and the mighty Charlotte Katakuri of the Big Mom Pirates. The crew itself has done things which most would think impossible and completely insane like defeating an entire organization (such as Baroque Works, CP9 and the Donquixote Pirates), punching a World Noble, breaking in and out of the judicial island, Enies Lobby, and crashing the tea party of a Yonko.
Currently, Luffy has gained the second highest known bounty in the world of 1,500,000,000 Berries and is unofficially titled the “Fifth Emperor of the Sea”, further signifying his ever-expanding growth and strength as well as his exploits throughout his journey to One Piece.
