Koala is mature, Fun, hard working, and also rather playful and cheery, and also She has also been shown to have a temper, as she got angry with Sabo for fighting Fujitora instead of staying at his post and comically pinched his cheeks for his disregard for his duties as a Revolutionary. Koala was deeply thankful to Fisher Tiger for freeing her and returning her home. Koala is good friends with Sabo, having worked with him since she was a teenager. As such, she's come to know him personally.
