10-QUEEN THE PLAGUE
Queen the Plague is an All-Star of the Beasts Pirates and one of Kaido’s three right-hand men, the Disasters. It has been implied that Queen is even stronger than the extremely powerful Jack.
Queen has the strength to stop a punch from Luffy with only one hand and then toss Luffy away, though these actions were done with his artificial arm. He also has tremendous durability as he was able to take a violent beating from the Yonko Big Mom and not suffer any visible bruises or injuries.
Edward Weevil, or “Whitebeard Jr.”, is the self-proclaimed son of “Whitebeard” Edward Newgate and one of the Shichibukai. His powers have been praised by Kizaru who compared his abilities to that of a younger Whitebeard, his alleged father.
He was able to single-handedly defeat 16 pirate crews affiliated with Whitebeard, including the A.O Pirates.
8-SENGOKU THE BUDDHA
Sengoku the Buddha was the Fleet Admiral of the Marines pre-timeskip, succeeding Kong and preceding Akainu.
Alongside Garp and Tsuru, Sengoku is one of the most powerful Marines of his generation. Even without his Devil Fruit powers, Sengoku has enormous strength, enough to effortlessly hold down an enraged Garp with only one hand.
Akainu is the current Fleet Admiral of the Marines, succeeding the previous fleet admiral, Sengoku.
He possesses tremendous physical strength, as shown when he pinned Whitebeard’s giant bisento down to the ground with just one leg. Furthermore, he was the one who emerged victorious from the ten day duel between him and Aokiji for the position of the fleet admiral.
Akainu’s background is renowned, especially among the stronger figures in the New World, striking fear into the hearts of pirates and marines alike. After Van Augur identified Akainu aboard a marine ship for negotiations, Blackbeard immediately fled, knowing the consequences of battling against him, even though Blackbeard had gained the powers of the Gura Gura no Mi, and had strengthened his crew with several of Impel Down’s most powerful criminals.
