"Gohan's Counterattack!" (孫悟飯の大逆襲！！ Son Gohan no Dai-Gyakushū!!, lit. "Son Gohan's Grand Counterattack!!") is the four hundred ninety-seventh chapter of the Dragon Ball manga.
Everyone wonders it is that has such a powerful ki, and Buu stands up to look as well. Piccolo thinks it may be a new enemy, until it gets closer and Piccolo realizes it's Goku. But Goten quickly corrects him, saying its Gohan. Piccolo can't believe it. Gohan lands in front of them, glad he made it in time. Gohan says Supreme Kai had saved him, and he had been with him until now. Piccolo thinks that he hadn't recognized him because he's somehow different now, even his facial features. The make-up of his ki is also different, with the softness gone. Gohan learns from Trunks that Majin Buu killed everyone, even his mom and Dende. Gohan is angry that everyone is gone, along with the Dragon Balls. Buu says they were delicious, but Gohan does sense a faint ki somewhere… Gohan smirks and walks up to Boo, staring him down. Buu questions whether he intends to fight him, while Gohan proclaims he intends to kill him.
Buu laughs, and remembers that he'd beaten up Gohan before. Piccolo thinks Gohan can't possibly win, and the boys prepare to use Fusion to help out. Gohan suddenly powers up and punches Buu in the face, kicks him, blocks a punch, kicks him again, punches him in the gut, kicks Boo into the air, follows after, and then kicks Boo toward the ground. Buu lands hard and quickly looks up to try to 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 Boo he's such a fool. Piccolo, Trunks, and Goten's jaws drop in astonishment.
