Used as a test subject for "human gigantification" experiments, resulting in a physique comparable to that of a giant child. Given candy containing the stimulant "NHC10" daily, leading to severe drug dependency. When the effects of the stimulant begin to wear off, withdrawal symptoms cause the child to rampage with the strength of a giant.

Lost in the Biscuit Room, the child asks Nami and others for help and is taken outside. Although Caesar brings the child back to the laboratory, remembering Nami and Usopp's words helps the child regain sanity. Chopper informs the child about the truth behind the candy and Caesar, and the child cooperates with him to escape the laboratory. To protect other children from eating the candy during withdrawal symptoms, the child consumes all the candy and collapses but is saved by Chopper and the others' efforts. After Caesar's defeat, the child is handed over to the navy for treatment. In the Egghead arc, the child is staying at the G-14 branch, and the treatment has slightly reduced the child's size.
