Template:Char box Uzu is a child living in Punk Hazard's Biscuits Room.[1]


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


Despite being very caring and friendly normally, Uzu turned hostile while under withdrawal symptoms from Caesar's drugs.[2]

Abilities and Powers

Due to her increased size, Uzu is quite powerful. After suffering from withdrawal symptoms from Caesar's drugs, she 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).


Uzu was taken from her family by Caesar Clown and brought to live on Punk Hazard as a test subject. At one point, she was introduced to Mocha.

When the Straw Hat Pirates arrived at Punk Hazard and broke into the Biscuit Room, Uzu 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, Uzu chased after her alongside the other children.


  1. One Piece Manga — Vol. 69 Chapter 686.
  2. One Piece Manga — Vol. 67 Chapter 665, Uzu and the other children suffer withdrawal symptoms due to NHC10 addiction.
