Charlotte Wiro is the 43rd son and the 80th child of the Charlotte Family. He is a Human-Snakeneck hybrid.
Wiro is a thin boy who, like all those of Snakeneck heritage, has a very long neck. He has wild dark red hair that covers his eyes. He wears a collared shirt and shorts.
Nothing is known about Wiro's personality. He has only ever been seen smiling.
Whole Cake Island Arc
Wiro was in the Whole Cake Chateau reading a book when Big Mom walked past him to meet with the Vinsmoke Family.
- Wiro's name may come from Uirō, a Japanese cake similar to mochi, which fits with the food-themed names of the Charlotte Family and Big Mom Pirates.
