Xiang Fei Tong is the leader of the triad known as the Ghost Boys. During the events of the Bebop & Rocksteady micro-series issue, Karai attended a meeting with Xiang in order to ensure her attendance at Shredder's upcoming meeting of underworld elements, as he had plans for the Ghost Boys. Xiang was secretly planning an attempt on his life.
However, the meeting was interrupted by Rocksteady and Bebop recklessly killing Xiang's followers outside. Believing this to be deliberate treachery, she vowed that she would not submit to Shredder and fled. Rocksteady and Bebop pursued and eventually caught up to her, but she managed to elude them long enough to flee the building. The police were waiting for her outside.
