"Gohan's Counterattack!" (孫悟飯の大逆襲！！ Son Gohan no Dai-Gyakushū!!, lit. "Son Gohan's Grand Counterattack!!") is the three hundred third chapter of Dragon Ball Z and the four hundred ninety-seventh overall chapter of the Dragon Ball manga.
Everyone wonders what it is that has such a powerful ki, and Super Buu stands up to look as well. Piccolo thinks it may be a new enemy, until it gets closer and Goten realizes it's Gohan, much to Piccolo's shock. Gohan lands in front of them, and reveals that the Supreme Kai had saved him from Fat Buu and taken him to the Sacred World of the Kai for special training. Piccolo realizes that he didn't recognize him because he's somehow different now, even his facial features have changed subtly. The make-up of his ki is also different, as it seems that any softness has gone. Gohan learns from Trunks that Super Buu murdered everyone on Kami's Lookout, including Chi-Chi, Videl and Dende. Super Buu laughs at this, saying that he enjoyed listening to their screams of terror as he killed them. An enraged Gohan walks up to Buu, staring him down. Buu questions whether he's "man enough" to fight him, but Gohan reveals that he's fully intent on killing Buu.
Super Buu scoffs at this, saying that he's already beaten Gohan before and he'll do it again. Piccolo thinks that Gohan can't possibly win, and the boys prepare to use the Fusion Dance to help out. Gohan suddenly powers up and punches Super Buu in the face, kicks him, blocks a punch, kicks him again, punches him in the gut, kicks Buu into the air, follows after, and then kicks Buu towards the ground. Buu lands hard and quickly looks up to try and find Gohan, but he doesn't see him. Buu is shocked to hear Gohan's voice right behind him, and turns to look. Smirking, Gohan tells Buu to give up, as he has no chance of beating him now. Piccolo, Trunks and Goten's jaws drop in astonishment.
