Biera

Biera (ビエラ) appears in the fourth movie. He was the stoker to the boiler on Gasparde's ship, the Salamander though forced to do so to protect himself and Anaguma (who calls him 'Grandpa').

At the start of the movie, he is stricken sick which prompts Anagama to leave the Salamander to try to help him. He come across Shuraiya Bascùd later on in the film. When Shuraiya tells him his past story, Biera realizes that Shuraiya and Anaguma are connected. As Luffy fights Gasparde, he blows up the boiler on the ship, causing it to sink and was thought dead.

However, Biera manages to survive (by putting lifesavers all over his body), as well as rescue Luffy and Shuraiya after Gasparde defeated. He then informs Shuraiya that he rescued a little girl from a river eight years ago who could only remember her name: Adelle Bascud, Shuraiya's sister whom Shuraiya thought was killed when Gasparde's crew destroyed their town. Biera convinces Shuraiya to accept her, despite his brutal life as a bounty hunter, and Shuraiya promises to start a new life for them.
