She is voiced by Sanae Kobayashi in the Japanese version of the anime and Laura Bailey in the English version, the former of whom also voices Namie Yagiri.
Xing Huo has black, long, extremely bushy and curled hair, and black eyes. Her dress may be an homage to the outfit worn by Freya in Chobits; it incorporates various uses of Fei Wong's bat-like symbol, which is also the shape of her hairbrush, worn up her left ear. She occasionally wears lipstick.
Xing Huo's true personality is difficult to ascertain. At first she seems to be malevolent and loyal to her master/creator, Fei Wong Reed. Though, she would frequently have doubts about Fei Wong's plans and didn't share his confidence that things will go his way. Unlike Fei Wong, she seemed to have at least some good in her. She betrayed her master by helping Tsubasa Li (original Syaoran) escape to Yuko to hinder Fei Wong's plans and potentially prevent many deaths from occurring as a result of his evil plans. Xing Huo is killed by Fei Wong for her betrayal, but, Fei Wong comments that her betrayal was likely inevitable.
She seemed to be at least somewhat attached to her fellow minion, Kyle Rondart.
Powers & Abilities
Xing Huo had very limited magical capabilities. She at least had the ability to transport another person across dimensions but she could only do it once. It is unknown what other magical powers, if any, she possessed.
