Mercenary Tao

Mercenary Tao, also known as Tao Pai Pai (桃白白 or タオパイパイ, Tao Pai Pai), is an antagonist in the Dragon Ball manga, and the anime Dragon Ball, also making two filler appearances in Dragon Ball Z. He is a highly skilled assassin-for-hire, as well as the younger brother of Master Shen. He charges a hefty price for his expert services, as he normally charges ten billion Zeni per kill, but gave Commander Red a 20th anniversary discount of five billion Zeni (fifty million in the Japanese version).<sup>[5]
