Suddenly Super Buu falls asleep, but Piccolo is not sure if he is pretending or not. Goten and Trunks test Super Buu by trying to pull his head tentacle, but Piccolo calls the two back. It seems Super Buu might sleep out the hour Goten and Trunks need, so they can do the fusion technique again.
Suddenly an incredible power rushes towards them, Piccolo thinks it is Goku, but Goten quickly reveals that it is Gohan, wearing his father's-style gi. Goten tells Gohan about how Super Buu ate all of their family and friends, but Gohan thinks he can sense Dende's power still.
Super Buu recognizes Gohan, and says that he has beaten him before, this gives him a lot of confidence. However, Gohan is not worried, as he has significantly improved since his last battle.
The battle begins, and Super Buu is unable land a punch on Gohan. Super Buu prepares the Gack! and Gohan successfully blocks the attack, causing Super Buu's body to become deformed, and Gohan punches Super Buu in the gut heavily, causing the steam in Super Buu's body to shoot out of every hole on his body. Super Buu then reveals that he is toying, and decides to fight properly, but still it is not enough and Gohan pummels Super Buu, angering him.
