Template:Char box Uzu is a child who was held captive in Punk Hazard's Biscuits Room.[1] He was freed with the rest of the children by the Straw Hat Pirates.


Uzu is a young boy with bushy black hair and an upturned nose. Due to the influence of Caesar Clown's drugs, he is larger than normal children.[2]


Despite being very caring and friendly normally, Uzu turned hostile while under withdrawal symptoms from Caesar's drugs.[3]

Abilities and Powers

Due to his increased size, Uzu 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).[4]


Uzu was taken from his family by Caesar Clown and brought to live on Punk Hazard as a test subject.{{qref| At one point, he was introduced to Mocha.[5]

When the Straw Hat Pirates arrived at Punk Hazard and broke into the Biscuit Room, Uzu escaped with Nami, Franky, Sanji, and Chopper.[6] However, Caesar eventually recaptured them and returned them to the Biscuit Room.[7] When Mocha tried to escape with the candy drugs, Uzu chased after him alongside the other children.[4]
