Bonham is a very physical person, as shown when he hugged and slapped Grount as expressions of friendship, with both being much too hard.[1] He is very eager to fight pirates and enemies, to the point where he competed with his comrade Grount over it.[5]



Bonham and Grount have a history together. They get along well even though Grount appears to be annoyed with him.


Alongside Grount, Bonham is well acquainted with Zappa, and they fought against Luffy and his group together.

Abilities and Powers

Physical Abilities

As a member of the Longarm Tribe, he has long, double jointed arms. Due to his large size, he has extremely high levels of physical strength, as he easily picked up Grount and easily overwhelmed him with mere hugs and playful hits.[1] He also easily destroyed thick wood and pierced metal when he attacked Luffy with Rokushiki techniques.

Breath Qigong

Bonham using Breath Qigong

Bonham was shown to utilize the Qigong technique called Breath Qigong to alter his body and improve his strength and speed.[5]


He is shown to be extremely proficient in Rokushiki, and was seen using Shigan, Rankyaku, Soru, Tekkai, and Geppo. Proclaiming himself to be a genius practitioner of the Rokushiki, Bonham could easily pierce a metal pot and wooden furniture and walls with Shigan, cut through two couch with a single Rankyaku, quickly block Luffy and Carrot pathway with a Soru and using Tekkai to withstand Luffy's Jet Pistol and emerge relatively unharmed despite being blown back with great force, which is a very notable feat as Blueno, a very powerful Rokushiki master, was easily damaged by the same attack.[5]



Bonham, All-Hunt Grount, and Shimoi Zappa were once subordinates under Admiral Aokiji before the latter left the Marines.[4]

Marine Rookie Arc

After Grount transferred to the Marine base, Bonham greeted him warmly when he arrived at the cafeteria. Bonham then got reacquainted with Grount even though Grount was annoyed. When Vice Admiral Prodi sounded the alarm and informed the base of Monkey D. Luffy's presence, Bonham and the other Marines quickly surrounded him.[1] Right after Luffy repelled Grount, Bonham fought against Luffy, who continued to evade his attacks. As Luffy and Carrot fled the cafeteria, Bonham tried to stop them, but Luffy was able to punch him aside. Grount, Bonham, and Zappa then pursued them to the food storage house.

Bonham fights Chopper.

At the storehouse, Bonham fought against Tony Tony Chopper. He initially overwhelmed Chopper with his Rokushiki, but Chopper managed to counter and eventually overpower him. He and Zappa later witnessed Grount's second fight against Luffy. After Luffy overpowered Grount, Bonham expressed concern for his Marine comrade.[5]

Bonham and Zappa are defeated by Luffy.

The pirates escaped to the coast, where they fought Prodi, and Bonham and Zappa wished to go there and continue fighting. Grount remained sitting sullenly on the ground, and Bonham reprimanded him, reminding him what Aokiji taught them before leaving with Zappa. Bonham and Zappa reached the coast right as Prodi was defeated by Luffy, and Bonham caught Prodi. He and Zappa then prepared to fight Luffy again, but the battle did not last long before they were defeated. Grount then arrived and confronted Luffy, revealing the true form of his left arm; Bonham and Zappa were excited that he had finally managed to control it. However, Grount was eventually defeated, and the Straw Hat Pirates escaped Fron Island. When Grount came to, Bonham and Zappa told him what happened, and the trio promised to win the next time they meet the Straw Hats.[6]
