Konbu is a child who lived in Punk Hazard’s Biscuits Room. He was freed with the rest of the children by the Straw Hat Pirates.


Konbu is a young boy with dark hair and no neck. Due to Caesar Clown’s experiments, he is larger than normal children.


Despite being a very caring and friendly child, Konbu turned hostile while going through withdrawal symptoms from Caesar’s drugs.

Abilities and Powers

Due to his increased size, Konbu is quite powerful. After suffering from withdrawal symptoms from Caesar’s drugs, he ganged up with the other children, making them strong enough to beat up Chopper in his Monster Point (even though Chopper was just trying to stop them, not hurt them).


Dressrosa Saga

Punk Hazard Arc

Konbu was taken from his parents by Caesar Clown and brought to live on Punk Hazard as a test subject. At one point, he was introduced to Mocha.

When the Straw Hat Pirates arrived at Punk Hazard and broke into the Biscuit Room, Konbu escaped with Nami, Franky, Sanji, and Chopper. However, Caesar eventually recaptured them and returned them to the Biscuit Room. When Mocha tried to escape with the candy drugs, Konbu chased after her alongside the other children. Eventually, when Mocha swallowed all of the candy and suffered a severe overdose, the children started to question why would the candy cause such pain, leaving them vulnerable to Chopper administrating a sedative. After Caesar’s defeat, Trafalgar Law used his Ope Ope no Mi powers to remove all of the NHC10 and other harmful substances Caesar implanted in the children. The G-5 Marines used the SAD Tanker to send the children home, with the intent on having Vegapunk help them return to their normal sizes.

While traveling with the G-5 Marines, Tashigi informed the children that they will see Dr. Vegapunk in a few days.
