#5 – BLACKBEARD
Blackbeard is theAdmiral of the Blackbeard Pirates and the newest member of the Yonko. He has an immense amount of superhuman endurance and tremendous physical strength even for his comparable size.
Blackbeard has become the first and, so far, only user to wield the powers of two Devil Fruits at the same time. With the power of darkness (Yami Yami no Mi), which “reduces anything to nothingness”, and the power of quakes (Gura Gura no Mi), which “brings destruction to everything”, Blackbeard claims himself to be truly invincible and the strongest pirate in the world.
The most prominent feats of Teach’s power was defeating three commanders of the Whitebeard Pirates: Portgas D. Ace, Thatch, and later during the Payback War, Marco, the new Captain of the Whitebeard Pirates.
#4 – BIG MOM
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 and tremendous superhuman durability due to her extremely tough skin. Mother Carmel believed she had the potential to become an Admiral or Fleet Admiral of the Marines.
Rayleigh is one of very few people who can use all 3 types of Haki: Busoshoku Haki, Kenbunshoku Haki and Haoshoku Haki.
Big Mom has acquired the powers of the Soru Soru no Mi a powerful Paramecia-type Devil Fruit that allows her to manifest the soul of whomever she touches into an ethereal substance. She can put harvested souls into non-living things in order to give them life or into animals in order to give them human abilities. Those creatures are named Homies. She can also use fragments of her own soul to create Special Homies that are far more powerful than ones created with other people’s souls: Zeus, a thundercloud she summons with her left hand; Prometheus, a sun she summons with her right hand; and Napoleon, a bicorne she wears on her head.
#3 – KAIDO
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 Moriah was in his prime, Kaido fought him and emerged victorious, having killed his entire crew. He was able to knock Luffy unconscious with a single blow!
Perhaps the greatest sign of Kaido’s 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.
Kaido has eaten a Mythical Zoan-type Devil Fruit that allows him to turn into a serpentine dragon. In this form, he is capable of flight and dark clouds fill the sky wherever he goes. He can also release devastating flames from his mouth, which can easily blow apart a large area.
#2 – SHANKS
“Red-Haired” Shanks is the captain of the Red Hair Pirates and a member of the Yonko. Shanks has mastered to full extent all three types of Haki.
His full fighting potential hasn’t been explored yet but there is a lot of hints that indicates Shanks is an extremely powerful individual. For starters, he was able to scare off a massive Sea King just by staring at it (until we figured out he used Haoshoku Haki: the strongest form of Haki). He also clashed evenly with Whitebeard, a fellow Emperor and even fought another, Kaido, and arrived at Marineford without a scratch on him. Additionally, he managed to ward off Ankinu where the savage admiral seemed a bit shocked at his presence and stopped going after Luffy after he came. Most of all, Blackbeard, who had the powers of the destructive Gura Gura no Mi Fruit and the evil Yami Yami no Mi Fruit chose not to fight Shanks saying “he is not strong enough to fight him yet”. That right there makes Shanks a force to be reckoned with and definitely one of the strongest guys in the series.
#1 – MONKEY D. DRAGON
Monkey D. Dragon is the infamous leader of the Revolutionary Army who has been attempting to overthrow the World Government. He is the World Government’s greatest enemy and is the most dangerous and most wanted man in the world. Dragon is already a powerful threat in his own right, as well as having powerful subordinates such as Sabo, Ivankov, Bartholomew Kuma, and Inazuma who are in comparison, lower in rank. This only speaks volumes of Dragon’s true power.
When he was mentioned at the Summit War everyone froze, just at the thought of Dragon. Everyone is scared of him. He is at least Yonko level. Maybe the strongest character of the series.
