Tamanegi

Tamanegi (たまねぎ) (called Onion in the English versions) was a member of Usopp's Pirates along with Ninjin and Piman before Usopp joined the Straw Hat Pirates. He uses a little shovel as a weapon. His ambition is to became an author.

He always disappears off somewhere. Then he'll come out from nowhere, screaming.
