Despite having mastered two new Super Saiyan transformations, Goku teaches Goten and Trunks to take his place . After his life is permanently restored, Goku attempts to fuse with Gohan in order to defeat Boo, but this fails when the latter is temporarily absorbed by Boo and so he persuades the newly arrived Vegeta to fuse with him, creating Vegetto (ベジット, Bejitto, "Vegerot" in Viz Media's manga translation). Eventually, Goku destroys Boo with a Genki - Dama attack . Ten years later, during another Tenkaichi Budōkai with fighters from all over the world, Goku meets Oob, Boo's human reincarnation, and leaves with him, intending to train him as the new protector of Earth . </P> <P> After defeating Majin Boo, Goku meets a new opponent known as Beerus, the God of Destruction in the canonical film Battle of Gods .

During this tournament, Goku reveals that he has learned to combine the perfect ki control of his Super Saiyan Blue form with his older technique, the Kaiō - ken; creating a variation called "Super Saiyan Blue Kaiō - ken". Although Goku gives up after fighting his opponent, Hit, his team ends up winning the tournament . Later, Goku encounters an evil counterpart of himself known as "Goku Black", who is terrorizing Future Trunks' timeline . Black is revealed to be Zamasu, who stole Goku's body and subsequently killed him and his family in another alternate timeline . After the omnipotent god from Future Trunks' timeline Zen - Oh is summoned by Goku, he erases the entire universe and Zamasu . Goku and the others present there manage to escape in their time machine, and later Goku and Future Trunks use the time machine again to bring Future Zen - Oh to the present timeline .

After enlisting nine of his allies to fight alongside him in the "Tournament of Power", Goku ends up recruiting Freeza as well . </P> <P> In the non-canon film Fusion Reborn, Goku and Vegeta use the Metamorese Fusion Dance, which creates Gogeta (ゴジータ, Gojīta), who sports slight visual differences from their previous merger .
