Uzu

Uzu is a youngster with a thick mop of brown hair and a nose that tips upward at the end. Caesar Clown's drugs have swollen his frame well past the size of an ordinary child, and like the other captive boys he is dressed in a plain white shirt.

By nature warm and easygoing, Uzu turns aggressive only when the withdrawal from Caesar's narcotic candy takes hold, the cravings overriding his gentler self.

Stolen away from his parents, Uzu was carried to Punk Hazard to serve as one of Caesar's gigantification test subjects and was introduced to Mocha during his captivity. His unnatural growth left him strikingly strong; once withdrawal set in, he and the other children mobbed Chopper in Monster Point and overpowered him, even though Chopper only meant to restrain them. When the Straw Hats broke into the Biscuits Room he slipped out with Nami, Franky, Sanji, and Chopper, only for Caesar to recapture the group. He chased Mocha when she fled with the drugs, and after she swallowed the whole stash and collapsed, the children's confusion left them open to Chopper's sedative. Once Caesar fell, Law used the Ope Ope no Mi to purge the implanted chemicals, and the G-5 Marines shipped the children home aboard the SAD tanker so Vegapunk could one day restore their normal size.
