Charlotte Linlin, more widely known as Big Mom, is the captain of the Big Mom Pirates and the only female member of the Yonko.
Big Mom has immense superhuman physical strength. When she was just five years old, she was strong enough to kill a large bear instantly with a single smack, merely intending to scold the animal, as well as break several of a giant’s bones by trying to slap a mosquito on their back. When suffering from her cravings, she could destroy a village in Elbaf and defeat several armed giants without a single scratch, being described by Jorl as an “evil god in the form of a child”.
She was strong enough to not only break Jorl’s sword with her fist when he tried to attack her, but also grab the giant’s beard, flip him over her shoulder, and smash him into the ground with enough force to mortally wound him.
Mother Carmel believed she had the potential to become an Admiral or Fleet Admiral of the Marines.
Kaido of the Beasts is the captain of the Beasts Pirates and one of the Yonko.
As one of the Yonko, Kaido is among the strongest pirates alive, renowned as the “Strongest Creature in the World”. He attempted to take Whitebeard’s life, something few would dare, and subsequently clashed with Shanks. When Gekko Moria was in his prime, Kaido fought him and emerged victorious, having killed his entire crew.
The greatest sign of his strength is his apparent inability to die due to his tremendous toughness and durability. 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.
Edward Newgate, more commonly known as “Whitebeard”, was the captain of the Whitebeard Pirates and was known as “The Strongest Man in the World”. He was a member of the Yonko that ruled over the New World until his death during the Battle of Marineford.
Whitebeard was given the title of the “strongest man in the world” for his physical power, which is far superior to even a giant.
Despite being old and sick, his physical resistance and pain tolerance were tremendous: he was able to keep fighting despite the number of life-threatening injuries he sustained, which included part of his head being burned off. No matter how much damage he took throughout the battle, Whitebeard continued to press forward and fight, only stopping once almost all of the Blackbeard Pirates collectively shot and brutally stabbed him to death at point-blank range.
He sustained 267 sword wounds, 152 gunshot wounds, and 46 wounds from cannonballs, and got half of his head blasted off, resulting in 465 injuries in total. However, even after taking so much damage in his already weakened state, he died standing, an impressive feat when compared to other characters. Even Teach was shocked by Whitebeard’s tenacity.
