"Muscle Tower's Final Hour" (マッスルタワーの最期！！ Massuru Tawā no Saigo!!, lit. "Muscle Tower's End!!") is the sixty-sixth chapter of the Dragon Ball manga.
Goku keeps demanding White return the elder, but White takes off his sweater and prepares to fight. White swings at Goku, but Goku ducks and lightly kicks White in the shin. It hurts, and White is mad now. White does the old “look over there” trick, and punches Goku in the gut while his head is turned. It doesn’t bother Goku, though, and Goku decides to show him a real punch. White bounces off the ceiling and lands behind his control desk. While back there, White spots his Powered Gun, and smirks.
White stands up and admits defeat, then goes into the next room and lets the elder free. Goku tells the elder that he and Hatchan are there to save him, and he beat up all of this bad guy's friends. Then White pulls the Powered Gun out of his back pocket and puts it to the elder's head, and Hatchan begs him to stop. Goku says that's dirty and White laughs at his misfortune. Then, the elder suddenly shouts out that he does not mind dying; just beat this guy up and bring peace to the village. Goku decides to do just that, but the elder says, “B-but… If you could, I’d be happy if you could rescue me as well…”
White tells Goku to turn around, and so Goku does just that. White then fires off the Powered Gun, hitting Goku in the back of the head, and knocking him out. Hatchan screams “Songoku!!!!” as White laughs with glee. White prepares to fire off a finishing shot at Goku, but Hatchan runs in the way and takes the shot himself, unaffected. Hatchan is really pissed now, and he puts his anti-violence policies aside to punch White straight through the tower wall, way out into the snow. Hatchan picks up Goku, who’s sore, but not dead, and explains how he wasn’t really hurt by the shot since he’s an Artificial Human. Goku, Hatchan, and the village elder all head down to the base of the tower back toward the village, with Goku complimenting Hatchan’s strength on the way down. As they come outside, Goku says he’s hungry, and they all laugh as they tread though the snow.
