Koala

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

Appearance
When he appeared twelve years ago, Koala was a skinny boy with long, unkempt hair. He had on a dirty, short-sleeved collared shirt, which he wore under overalls. He has a smudge on his right cheek. He also has distinctively large and round eyes, similar to that of a koala. He always smiles.

Personality
One Sunny Pirate described Koala as having the lifestyle of a slave ingrained into his body, even after being set free. He 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 his masters, as he asked them if he would be killed if he 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 him to his homeland. When the Sunny Pirates visited there three years after he was freed, the inhabitants asked them to take the boy home. After Koala introduced himself and thanked Fisher Tiger for freeing him, he boarded the Sunny Pirates' ship. Koala was instantly met with hostility by Arlong, who hit him for being human, but was restrained by Hatchan. Fisher Tiger then gave the boy a mark of the sun to cover up the slave mark. Fisher Tiger then told the boy that he was allowed to cry if he wished and made a vow to return the boy to his home. Koala then began to cry.
