chall acustica

Main protagonist of Gundam 00P's first season.

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.

She's voiced by Aida Rikako (00P version) and Kaida Yuuko (00F version) in SD Gundam G-Generation Cross Rays.
