Kibagaeru

Kibagaeru was the former captain of the Fanged Toad Pirates until he lost to Foxy at the Davy Back Fight and joined his crew.

Appearance
Kibagaeru is a wide-framed man with a gray mustache. He is dressed in elaborate pirate clothes, including a orange vest with a light purple tucked-in scarf, a blue captain's coat and a tricorne that had his crew's Jolly Roger on it. Upon joining the Foxy Pirates, he has crossed out the Jolly Roger on his hat, signifying his defection from his old crew, and donned an eye mask that the rest of the crew wears.

Personality
As a pirate, Kibagaeru follows the code of honor quite strictly, as he adhered to the rules of the Davy Back Fight, and joined the opposing crew upon losing, even if it means abandoning his old crew, as well as losing his captaincy.

Davy Back Fight Arc
Kibagaeru, as the captain of the Fanged Toad Pirates, was challenged by Foxy and his crew into a Davy Back Fight. They had five matches, and Kibagaeru and his crew lost all five, thus resulting in Kibagaeru and the crew's essential members (doctor, shipwright, and navigator) and jolly roger being taken by Foxy, leaving the crew in a wreck. Later, when the Straw Hat Pirates questioned about the challenge, Kibagaeru and his old colleagues happily revealed that they defected from their old crew and joined the new one willingly, showing the seriousness of the fight.

Manga and Anime Differences
After the Straw Hats' encounter with Noko, in a short anime filler arc, Kibagaeru took over the Foxy Pirates after Foxy lost the last event of the Davy Back Fight, and refused to allow Foxy back. After a fight against him, and the Straw Hat Pirates, he finally decided to let Foxy rejoin his crew.

Translation and Dub Issues
Kibagaeru was not named in the manga. He was first named in the ending credits of the anime, in a very vague manner, as "Kiba captain". His official name was revealed in One Piece Blue Deep: Characters World.

Kiba (牙) means "fang" in Japanese.
