Soro


 * Not to be confused with Roronoa Zoro, the swordsman of the Straw Hat Pirates.

Soro was Helmeppo's pet wolf that had been released to frighten Shell Town's citizens. The manga simply states that Soro attempted to attack a young girl named Rika, but Roronoa Zoro saved her by killing the wolf. The anime goes into more detail, showing Soro, upon entering a restaurant owned by a woman and her young daughter, Rika, began frightening off customers. Rika tries to stop the wolf until her mother warns her that she'll be punished for angering Helmeppo. As Rika realizes her mistake and reluctantly moves away from Soro, the wolf then attacks her. Zoro steps in, simply throwing a chair at Soro and knocking the wolf aside. Helmeppo demanded to know who Zoro was, before realizing he was the famous pirate hunter, Roronoa Zoro. Helmeppo demands to know why a pirate hunter is defying the marines, but Zoro ignores him for the most part, telling Helmeppo to leave and let him enjoy his meal in peace.

After this episode, Soro does not reappear in the anime or the manga, though Helmeppo does.
