Koala

Koala is a former slave who was set free by Fisher Tiger's rampage on Mariejois. She sailed along with the Sun Pirates to reach her home town.

Appearance
When she appeared twelve years ago, Koala was a skinny girl with long, unkempt hair. She also had distinctively large and round eyes, similar to that of a koala, and was always smiling.

She had on a dirty, short-sleeved collared shirt, which she wore under dark overalls and a smudge on her right cheek.

Judging from the way Fisher Tiger branded her on her back, she had the mark of the Celestial Dragons on her back, which was replaced by the mark of the Sun Pirates.

After a few weeks she has neat, shoulder-length hair, a light-colored dress, and a pair of loafers.

Personality
Aladdin described Koala as having the lifestyle of a slave ingrained in her blood, even after being set free for three years. She was very apologetic and vowed to never cry or stop working. The pirate explained that if a slave ever cried or stopped cleaning, then they would be killed.

Koala seemed to consider the Sun Pirates her masters, as she asked them if she would be killed if she stopped cleaning. The pirate also said that slaves panicked constantly, even when they were by themselves, and could never trust anyone. It is unknown if Koala also became paranoid in that regard.

By the time they reach her home town she genuinely liked the fishmen and mermen of the Sun Pirates, creating especially strong bonds with Hatchan and the members of the Macro Pirates. She went as far as to actually hold Fisher Tiger's hands despite him trying to shake her off.

Sun Pirates
Koala was much loved during her time with the Sun Pirates. As the crew included former slaves, they understood the plight that Koala had suffered and why she was how she was. They treated her and protected her while she traveled with them and were very sad to see her go.

Fisher Tiger
Koala was deeply thankful to Fisher Tiger for freeing and returning her home. Though she appeared to like the fishmen, Fisher Tiger himself admitted that he was unable to love humans upon his deathbed so he could not return affection towards her. He even refused to hold her hand, though he still smiled when she returned home.

Arlong
Arlong spent the entire time objecting to her presence on the Sun Pirates' ship, attempting to beat or kill her for being a human. Koala seemed to have left a long-term impression on Arlong as it seemed, notably, in the final moments of his fight with Luffy, Arlong stated that as long as Nami was fed and well-clothed, she was happy. As a slave, Koala had little much to her name and what made Koala happy was the things she had missed while being a slave such as nice clothes and suitable meals.

History
After Fisher Tiger attacked Mariejois, Koala escaped and fled to an island. Unfortunately, the inhabitants there had no way of returning her to her homeland. When the Sun Pirates visited there three years after she was freed, the inhabitants asked them to take the little girl home. After Koala introduced herself and thanked Tiger for freeing her, she boarded the Sun Pirates' ship.



Koala was instantly met with hostility by Arlong, who hit her for being human, but was restrained by Hatchan. Tiger gave the girl the mark of the sun to cover up her slave mark. He then told the girl that she was allowed to cry if she wished and made a vow to return the little girl to her home. Koala then began to cry.



The Sun Pirates were able to find an Eternal Pose for her home island, Foolshout Island. When they arrive, she bid everyone farewell, and Tiger took her to her village. The whole town rejoiced, but everyone was still afraid of Tiger.

Later, she heard some strange noises. When she asked if anyone else heard them, her mother replied no. The truth was that Fisher Tiger was attacked because people from a previous island informed the Marines about the Sun Pirates while the people on this island allowed it on the condition that the Marines overlook the fact that she was a released slave and not take her back.
