The Fist of Son Goku (孫悟空勝つ！！ Son Gokū Katsu!!, lit. "Son Goku Wins!!") is the one hundred sixty-first chapter of the Dragon Ball manga.
The cover of this chapter shows an injured Goku making a peace sign with his fingers.
Picking up from the previous chapter, the chapter starts out with Goku flying towards King Piccolo. The demon desperately tries in vain to block Goku, but is completely pierced through his chest by Goku's body. Before dying, King Piccolo spits out an egg containing his last son and he then explodes, disappearing once and for all. Goku falls to the ground and is caught by Yajirobe, who takes him away in his hovercar. The others catch up with Tien Shinhan, and Bulma tells the TV station that Piccolo is dead and the world is safe. The chapter ends on an anonymous note with Piccolo Jr. hatching from his egg and claiming that he will avenge his father.
