Goku's Final Gamble (孫悟空最後の賭け!! Son Gokū Saigo no Kake!!, lit. "Son Goku's Final Gamble!!") is the one hundred sixieth chapter of the Dragon Ball manga. The chapter's anime counterpart is the middle portion of the episode "Final Showdown".
Piccolo threatens to kill Tenshinhan if Goku moves, but Tenshinhan tells him to just kill Piccolo and not to worry about him. Piccolo thinks he’s said too much, and starts to squeeze Tenshinhan’s head. Goku yells to stop, and says he’ll do as he likes. Piccolo tells him not to move, and then picks up a rock and blows it at Goku, disabling his left arm. Piccolo says that humanity’s weakness is its generosity, and Goku hesitates, then insists that they’ll kill him somehow or other, and Piccolo asks how. “Ten-san, forgive me! I’m gonna defeat Piccolo!!!”
Piccolo can’t believe he’d just let him die, and Goku insists he’ll return him to life with the Dragon Balls. Piccolo laughs and says how he got rid of Shenlong, and Goku can’t believe it. Goku’s at a loss again, and so Piccolo blows another rock at him, taking out his left leg, and knocking Goku down. Piccolo laughs at how Goku can’t stand up right now, he’s like a green caterpillar. Piccolo doesn’t need Tenshinhan anymore, so he drops him to the ground. He’ll take this one out later, but first he needs to take care of the brat.
Piccolo laughs at how Goku can’t do anything, so it finally ends here. Piccolo flies high up into the air, and prepares to take out this person who’s kept him from making this a world of darkness. Piccolo then dives down at Goku, but Goku says he’s mistaken, he has one remaining arm. Goku charges up this arm, then points it down at the ground, and fires |a Kamehameha down, projecting himself into the air toward Piccolo. Goku puts everything into this fist, as Piccolo prepares to fire a counter blast down at him.
