Jinbe

Former Warlord of the Sea and the second captain of the Sun Pirates. Jinbe, a shark fish-man, is known by the epithet "Knight of the Sea." A master of Fish-Man Karate, he values loyalty and honor, earning him the affectionate nickname "Boss" from the residents of Fish-Man Island. He reunited with the Straw Hat Pirates on Fish-Man Island and quelled the civil unrest caused by the New Fish-Man Pirates. Later, he was invited to join the Straw Hats by Luffy, but he declined due to his obligations to Big Mom, promising to join after settling things with her.
