Koala

As a girl of roughly eleven, Koala was slight, her long brown hair left unkempt and her big round purple eyes echoing the animal she shares a name with, almost always set in a smile. She wore a grubby short-sleeved collared shirt beneath dark-brown overalls, a smudge marking her right cheek, and the Celestial Dragons' brand sat on her back until Fisher Tiger replaced it with the Sun Pirates' mark. Weeks on, her hair was trimmed neatly to her shoulders and she took to a yellow dress trimmed with an orange diamond pattern and orange loafers.

By twenty-three she had grown taller, though she stayed rather short at 160 cm, turning slender and curvy, with the anime recoloring her hair from light brown to the orange of the manga. Her grown-up outfit features a crimson newsboy cap fitted with gold goggles and a frilly-collared pink shirt; below the waist she wears black shorts beneath a maroon skirt of micro-mini length, plus brown gloves and brown heeled boots over black thigh-high stockings.

The reflexes of bondage ran so deep that, even years after her release, Koala stayed apologetic and swore never to weep or rest from her chores, since any slave who cried or stopped cleaning faced death. She at first treated the Sun Pirates as masters rather than rescuers. Only after Fisher Tiger cast his gun into the sea to prove his crew differed from the World Nobles did she finally weep for the first time in many years, thereafter regarding the crew as her family.

Grown to adulthood, Koala became warm, playful, and now and then quick-tempered. She comforted Sabo over his inability to save Ace, gleefully threw her arms around Robin upon meeting her, and comically pinched Sabo's cheeks whenever recklessness such as dueling Admiral Fujitora pulled him from his post.

Snatched away as a child and sold to the World Nobles, Koala was among the countless slaves set loose when Fisher Tiger stormed Mary Geoise. Stranded on an island that could not return her home, she was finally taken aboard three years later, after the Sun Pirates were asked to carry her back. Arlong greeted her with violence for being human, yet Tiger covered her slave mark with the Sun emblem and promised to deliver her to Foolshout Island. Once she was home, the townspeople quietly sold the Sun Pirates out to the Marines in trade for letting her remain free, a betrayal that led to Tiger's death.

Three years on, at fourteen, Koala enlisted in the Revolutionary Army and studied under Hack to become an assistant instructor of Fish-Man Karate, a striking feat for a human, growing close to Sabo along the way. Her skill lets her topple far larger foes with great agility. During the Dressrosa Arc, she, Sabo, and Hack arrived to halt a weapons trade fueling wars across the world; she slipped into the Corrida Colosseum disguised as a Donquixote Pirate, exposed that the trade-port's pirate ships were really merchant vessels in disguise, and helped the revolutionaries carry off the weapons and evidence before CP0 could seize them.

Back at Baltigo, she informed Dragon that the recovered arms held Liquor Iron Ore, a lead on where they were forged. After Blackbeard razed Baltigo, the army shifted its base to Momoiro Island. In the Final Saga's Egghead Arc, Koala stood beside Dragon as they wrestled with reports that Sabo had slain King Cobra, grieved at the sight of the rescued Kuma reduced to a Pacifista, and broke down with relief when Sabo came home safe to Momoiro Island alongside the Lulusia survivors.
