During the Majin Buu story arc, Son Goku is deceased for the majority of the storyline and thus acts mainly in a supporting role, aiding Goten and Trunks in learning the fusion dance and helping Gohan train to fight Majin Buu. However, while watching the events of the battle with Majin Buu, he witnesses Buu absorb Gotenks and Piccolo and realizes that Gohan, the only remaining fighter, is completely outmatched. He is then resurrected and returns to Earth, planning to fuse with Gohan so that they can defeat Buu. However, before they can fuse, Buu reverts from Gotenks form as Goten and Trunks defuse inside of him. Goku believes there is no need for him and his son to fuse as Gohan could easily defeat Buu. However, Buu uses another piece of his body to sneak up on and absorb Gohan as well.
Knowing that he cannot defeat the newly-empowered Buu on his own, Goku desperately tries to think of someone to fuse with, but can find no viable candidates. Luckily, the Saiyan Vegeta returns from the dead with the intent to fight Buu and Goku convinces him to fuse with him. The two become the fused warrior Vegito and easily overpower Buu. Wanting to save the others who have been absorbed by Buu, Vegito forces Buu to exhaust all his options until he resorts to absorbing him. Taking the bait, Buu uses a piece of himself to engulf Vegito, and Vegito is pulled into Buu's body. Using an energy shield, Vegito manages to avoid being absorbed and is given free reign inside Buu's body. Vegito then inexplicably defuses back into Goku and Vegeta and the two search Buu's body for their trapped sons and Piccolo. The two manage to rescue all of them, as well as untether Good Buu, and then escape from Buu's body.
Shortly afterwards, Majin Buu reverts to his Kid Buu form and blows up Earth. Goku and Vegeta manage to escape in time and then concoct a plan to restore Earth and all the people Buu has killed. Goku then uses the energy from as many people in the universe as he can to conjure a Spirit Bomb that destroys Majin Buu once and for all.
