A capo in the Red Dragon Crime Syndicate. Mao took Spike Spiegel and Vicious into the syndicate when the two were very young and spent years training them for leadership positions. When Spike faked his death and left the Syndicate, Mao had a lot of people out looking for him. In his last years, Mao was pioneering a movement towards more peaceful business, and cooperation with other syndicates. However, his vision was not meant to be, as he was assassinated by Vicious shortly after signing a peace treaty with the White Tiger Syndicate.
