Kasagoba[1] is a marbled rockfish fishman and was a member of the now disbanded New Fishman Pirates prior to their downfall.[2] In the anime, he is named Kasagon (カサゴン Kasagon?).[2]


He is a stocky, beige fishman with brown spots on his thick neck. He has pink trailings with yellow on the tips on his head and neck. He also appears to wear a white tank top and vertically striped pants. He also has a very large grin.


As a member of the New Fishman Pirates, Kasagoba most likely has a strong hatred for humans.

Abilities and PowersEdit

As a fishman, he was born with natural strength ten times that of a normal human, which is doubled underwater. However he is easily knocked out by Luffy's single punch.


He wields a pike, although he was not shown using it in combat.


Fishman Island SagaEdit

Fishman Island ArcEdit

Kasagoba first appeared alongside Hammond and Hyouzou, riding on sea beasts right outside of Fishman Island. They intercepted the Straw Hat Pirates and gave the crew two choices; join the New Fishman Pirates or be crushed before being able to enter the island. After Luffy rejected the invitation, the Straw Hats used the their ship's Coup de Burst to launch themselves into the island. Kasagoba was surprised by the ship's unexpected maneuver. After wondering what to do next, they returned to the Fishman District to report to their captain.

Kasagoba, alongside Hammond and Hyouzou, later went to Mermaid Cove in another attempt to capture Luffy, but they were easily repelled. The attack knocked out Hammond and Kasagoba, but Hyouzou was able to block it and remained uninjured. After the Straw Hats left the cove, Hyouzou carried his two unconscious companions away.
