She was a Second Generation Gundam Meister and designated pilot of the Gundam Plutone.
She has long, brown hair and blue eyes. However, due to a catastrophic tragedy which involves the Gundam Plutone and claimed the lives of her fellow Meisters, Ruido Resonance and Marlene Vlady, Chall's hair turned white, and she gained a huge scar on her left body and left eye. She retained her new appearance when she returns in 00P second season and its sequel, Gundam 00F.
