Koala is a little girl who was freed from slavery under the Celestial Dragon. She joined the Sun Pirates on their journey to return her home.
Koala is a young girl who was abducted and sold into slavery to the Celestial Dragons and branded with their mark, like all the other slaves. While captive in the Holy Land Marie Jois, Koala witnessed other slaves who either cried or rested were ruthlessly killed. In order to survive and one day see her mother again. She hardened herself to never cry and work no matter how she suffered. She eventually was able to escape when the fish-man Fisher Tiger attacked Marie Jois and freed all the slaves regardless of their race.
Koala is a supporting character in the One Piece series that was created by Eiichiro Oda. The series first began serialization in Weekly Shōnen Jump on August 4, 1997. She first appeared during the Fish-Man Island Arc that began in Volume 61.
Her first appearance was in One Piece Volume 63 CH. 622 "The Sun Pirates", and her first anime appearance was in One Piece - Episode 541 "Kizaru Appears! A Trap to Catch Tiger!". Her character in the Japanese series is voiced by Yuki Inoue, and the U.S. dub produced by FUNimation has yet to be announced.
Koala had been living with some monks, who were also escaped slaves, on an island in the Grand Line. That was until the day that Fisher Tiger's own pirate crew, the Sun Pirates, came to their island. The monks convinced them to take Koala with them so she could be returned home. Still living in the trauma of slavery, Arlong struck her for her empty smiling face, and he hated humans. She in response just started cleaning and begging them not to kill her. Many of the crew were shocked at her actions. Tiger took her to his room and used his own brand of the Sun Pirates to cover her slavery brand. She passed out, but woke up with no change. Tiger had been trying to let her know that it was alright to cry. They weren't like the Celestial Dragons. To prove so, Tiger tossed his gun into the ocean and commanded his crew to set sail so they could take Koala home. For the first time in years, Koala cried out in joy that she's be going back to her mother.
Koala had finally broken free of her past trauma, and the Sun Pirates were able to have her hair done and get her proper clothes. They were eventually able to find an eternal pose to Foolshout Island. She had become close to several of the crew and said her farewells when they reached her island. Tiger took her to her village. Many of the people were afraid of the fish-man, but Koala still hollered after him to thank him for bringing her home. She later heard loud noises in the distance that everyone else pretended not to hear. She didn't know that people on a previous island had tipped the Marines to their destination, and what she had heard was the Marines attacking Tiger. She never knew that the injuries he suffered in the fight would eventually lead to his death.
