Konbu

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.

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

Personality
Despite being very caring and friendly normally, 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).

History
Konbu was taken from his family 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.
