Biera

Appears in the fourth movie. Biera (ビエラ) 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. When he come across Shuraiya Bascùd late in the film who tells him his past story he realizes that he 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 over his body) as well as rescues 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, who is Shuraiya's sister whom he thought was killed when Gasparde's crew destroyed their town. Biera then convinces Shuraiya to accept her, despite his brutal life as a bounty hunter, and to start a new life together.
