Tao Pai Pai

Mercenary Tao (桃白白, Tao Pai Pai) is a highly skilled assassin-for-hire and the younger brother of Master Shen. He is very expensive to pay 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).
Tao is shown to be extremely psychotic and sadistic, taking a lot of joy in killing people. He also has absolutely no qualms in regards to murdering children, as evidenced when, shortly after Upa attempted to avenge his father, Tao stated that Upa should be lucky that he even survived. He is also extremely rude, expecting everyone to do everything he wants with no return favor. He is also shown to be a coward when confronted with an enemy he can't beat, resorting to dirty tactics to beat them, as evidenced by his attempt to throw a grenade at Goku after begging for mercy and promising to change his ways.
