After Baby takes control of Vegeta's body and brainwashes everyone on Earth except for Goku, Pan, Mr. Satan, Buu and Uub; the Z Fighters stand against the Tuffle. Goku goes to Super Saiyan 3 but in his childhood body he cannot hold it for long. Baby then transforms and transforms again. When Goku is unable to fight anymore, Uub who has now become Majuub confronts Baby. After a while, Goku returns and transforms into a Super Saiyan 4. When Baby is nearly defeated, he transforms into a Golden Great Ape. Using the full power of all the Z Fighters, Goku defeats Baby, making the Tuffle race extinct.
Rather than the full battle, the battle can also be won with Goku in normal or Super Saiyan 3 form or Majuub. Also, when losing with Goku SSJ4 before Baby transforms, you can switch to Pan.
