Sofia has bright red hair, which is long and wavy. As a Haos brawler, most of her clothes are yellow or white; however, her barrette is a dark blue, and her hair tie is a blue-green color.
Sofia's long hair is very thick as well, which is both good and bad for her. Although it looks beautiful, she is forced to spend an hour each day taking care of it.
Although ditzy and light-spirited, Sofia is extremely intelligent. She was able to figure out a weakness in the Gundalian fortress after only reading the blueprint once.
A running gag in the series is that whenever Sofia gets mad, her aura makes her hair fly up, resulting in an hour spent getting her hair back to normal. Poor Aaron is usually the one that has to help her brush her long hair.
Sofia becomes a major part of Bakugan: Gundalian Invaders. After Lyrica Volan returns, she becomes her attendant and the new Haos brawler for the New Vexos, or the Yemon (Guarding the Gate).
Her first appearance to the Brawlers was during the invasion of Kazarina's Lab, where Sofia came with Aaron to stop Kaya Shishidou from destroying everything.
