History
After growing up in a rough part of Fish-Man Island, Jimbei first joins the island's royal army and later the Sun Pirates; he becomes captain following the death of Fisher Tiger. In exchange for the World Government granting him Warlord-status, Jimbei eventually disbands the crew. He was a former friend of Arlong, having once fought together until differences in opinion regarding the human race forced them to split apart. Since then Jimbei fights for the sake of all those in need regardless of their race.

He resigns his Warlord position to side against the Government during its war with the Whitebeard Pirates, the protectors of Fish-Man Island. Two years later, he turns down an invitation to join the Straw Hat Pirates, stating that he needs to take care of unfinished business before joining them. After cutting ties with Big Mom, he eventually joins the Straw Hat Pirates as the crew's helmsman, although they are separated when he goes to help his old crew, escape from Big Mom.
