To fight against Vegeta, Goku performs his Kaiō-Ken technique to multiply his energy but is left considerably exhausted. After being overwhelmed in battle, Vegeta creates an artificial moon to turn into a Great Ape, and starts torturing the weakened Goku. Gohan, Kuririn and Yajirobe go to Goku's aid and manage to cut off Vegeta's tail, returning him to his human state. Vegeta is still able to fight them and Goku hands over the remainder of the Genki-Dama he had formed to Kuririn. Kuririn throws the Genki-Dama at Vegeta who dodges it, but Gohan manages to reflect it back at Vegeta, who manages to survive the attack. As Vegeta prepares to kill the group, Gohan's Saiyan tail appears, causing him to turn into a Great Ape. Gohan almost kills Vegeta, but his tail is cut off at the last moment.
