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. They are aiming for the Ancient Weapons and the One Piece. 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. Now he is leading the Supernovas in the battle that will lead to the fall of Yonko Kaido and Big Mom.
Currently, Luffy has gained the 7th highest known bounty ever 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.
