Doni is a small boy with short brown hair. He notably wears a large cooking pot on his head. He wears a patched-up yellow shirt that is too small for him, a blue vest, a light blue ascot around his neck, a sash of the same color around his waist, short blue pants, and brown shoes.
Doni was with Jeanne on the coast of Jail Island when she saved Monkey D. Luffy from drowning. He grew fearful upon finding out Luffy was indeed a pirate, but tensions calmed after Luffy revealed he had no knowledge of the stones on the island.
