Koala

Koala is a slave who was set free by Fisher Tiger's rampage on Mariejois.

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.

Personality
One Sunny Pirate described Koala as having the lifestyle of a slave ingrained into her body, even after being set free. 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 Sunny 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.

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 Sunny 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 Fisher Tiger for freeing her, she boarded the Sunny Pirates' ship. Koala was instantly met with hostility by Arlong, who hit her for being human, but was restrained by Hatchan. Fisher Tiger then gave the girl a mark of the sun to cover up the slave mark, who 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.
