At Wano Country, the One Piece manga saw the formation of the biggest known power when Kaido and Big Mom decided to join hands to take down Luffy. With the Big Mom Pirates and the Beasts Pirates now having joined forces, the new crew thus formed comprises of some very powerful pirates.
These range from Kaido's Calamities to Big Mom's Ministers. They're all impressive fighters and make up for the bulk of the new Rocks' forces. Here are the 10 strongest known members of the Kaido and Big Mom alliance that we know of.
10 Charlotte Oven
Charlotte Oven is one of the Ministers of the Big Mom Pirates. He has a bounty of 300 million berries on his head, however, it certainly doesn't do any justice to his strength.
As seen throughout the Whole Cake Island arc, Oven is tremendously powerful and his skills are great enough to match some of the strongest characters, such as the right-hand of Jinbei, Aladin. Oven's Devil Fruit ability is pretty powerful as well and his skills are great enough for him to be considered one of the strongest of the Big Mom - Kaido alliance.
9 Charlotte Perospero
A strong pirate with a bounty of 700 million berries, Perospero is directly under the Sweet Commanders and has high authority among the Big Mom Pirates. He is incredibly powerful and his strength is such that he's able to overpower multiple Straw Hat pirates at once.
Perospero has the ability to manipulate candy at will, thanks to his Pero Pero no Mi. On top of that, he's a decent user of Haki as well. Interestingly, Perospero's control on his Devil Fruit is what makes him deadly and we're sure that he's worthy of taking this spot on the list.
8 Charlotte Cracker
One of the Sweet 3 Generals of the Big Mom Pirates, Charlotte Cracker is an extremely powerful pirate. He has a bounty of 860 million berries on his head, which means he's a deadly foe for anyone to encounter.
Cracker's Devil Fruit ability, known as the Bisu Bisu no Mi, is what makes him so special. It has earned him the title of 'Thousand Arms' Cracker and few actually get to see his powers. On top of everything, his Armament Haki is known to be extremely powerful, which is why he takes the 8th spot on the list.
7 Jack
Jack is one of Kaido's three right-hand men, also known as the All-Stars. He is a pirate with a bounty of a billion berries and his skills are far greater than the likes of the fodder pirates in Kaido's crew. Jack is a user of an Ancient Zoan type Devil Fruit known as Zou Zou no Mi Model: Mammoth.
If that wasn't enough, he is also extremely durable and his strength knows no bounds. He has even clashed against some Navy Admirals in the series and survived, which is part of what makes him so great.
6 Queen
Like Jack, Queen is also one of Kaido's right-hand men and a member of the All-Stars. He has a bounty of 1.3 billion berries on his head, which just goes to show how dangerous a pirate he really is. Queen's powers aren't to be underestimated and it is easy to see that he's one of the strongest of this alliance.
Queen wields an Ancient Zoan Devil Fruit known as Ryu Ryu no Mi, Model; Brachiosaurus which grants him the strength of the said creature. He is also known to be very well versed with toxins and had the reputation of being an assassin as well. Queen is very powerful, to say the least.
5 Charlotte Smoothie
With a bounty of 932 million berries on her head, Charlotte Smoothie takes the spot of one of the strongest members of this alliance. Although her bounty is lower than that of Jack and Queen, that barely means anything. Smoothie's powers are incredible, no matter which way you look at it.
She's a powerful swordsman and she has the power of the Shibo Shibo no Mi to aid her in battle. Smoothie can wrench out the water from a user's body at will and even transform herself into a giant. As expected, she is also a master swordsman, which is what makes her a big threat to anyone who stands in her way.
4 King
Kaido's strongest subordinate, King is the leader of the All-Stars and a fearsome pirate. Although his bounty isn't known, it is likely going to be higher than that of Queen. King wields tremendous power, thanks to his Ancient Zoan type Devil Fruit, known as the Ryu Ryu no Mi, Model: Pteranodon.
King's strength and speed are such that barely anyone can track him when he's in the sky. He also seems to wield a sword, which means that his strength is beyond that of a normal pirate. Undoubtedly, King is someone who we hope to see more of in the future.
3 Charlotte Katakuri
Katakuri is the leader of the Big Mom Pirates' Sweet Commanders and he's one of the strongest known pirates in the world of One Piece. Katakuri has a bounty over a billion berries, as revealed in the Whole Cake Island arc. He holds the power of the Mochi Mochi no Mi, which is a special paramecia type of Devil Fruit.
Perhaps his biggest known power is the ability to be able to look into the future with his Observation Haki. In all his life, Katakuri has fought many pirates, and maybe even the strongest of Navy, and he is known to have never lost a single battle, except for being defeated by Monkey D. Luffy.
2 Kaido
The leader of the Beasts Pirates and one of the Emperors of the Sea, Kaido is an incredibly powerful pirate whose strength knows no bounds. When it comes to raw strength alone, Kaido is easily the strongest in the entire world of One Piece.
He has a Mythical Zoan type Devil Fruit that allows him to transform into a dragon at will. Kaido's durability is insane, having only received one scar in his entire life. Despite that, Kaido has lost to his fellow Yonko or the Navy a combined 7 times in total and he also has been captured 18 times. Furthermore, Kaido's duel against Oden proved that he isn't invincible and he only won it by cheating.
1 Big Mom
Big Mom is one of the Emperors of the Seas, just like Kaido, and she is a tremendous pirate. Her strength is phenomenal and second to none. She wields the power of the Soru Soru no Mi that allows her to manipulate souls at will.
In terms of fighting prowess, Big Mom proved to be equal to Kaido at Onigashima when the two fought, despite being weakened by the sea prism stone and not having Zeus and Prometheus, two of her strongest allies, by her side. Unlike Kaido, she isn't known to have lost even a single battle and has never been wounded either. Big Mom may be looked down upon by some, but she's truly a majestic pirate.
