Universal Allies / Until We Meet Again.Episode 63 Universal Allies: Omega Shenron is through playing games. He creates a giant energy ball and hurls it at the Earth. Vegeta prepares to attack it, but Goku knocks him aside and tries to push it back. After a long struggle, Omega's power is too much, and the ball explodes. Goku prevented the Earth from blowing up, but seemingly died in the blast. Vegeta, Trunks, Gohan, and Goten all attack Omega Shenron, but are quickly beaten. Omega then once again floods the Earth with negative energy, and Vegeta, seeking to avenge Goku's apparent death, charges, only to be defeated quickly. Before losing consciousness, Vegeta assures him that he hasn't won yet, which proves true as a still-living Goku rises from the crater, holding a Spirit Bomb. He has gathered all the energy from the Earth, but it's not enough. He tells King Kai to ask the entire universe for power. During this time, Omega repeatedly blasts Goku, but cannot damage him, due to the immense amount of energy that Goku is now in possession of. Energy from all over the universe gathers on Earth, and the phenomenally powerful Universal Spirit Bomb is completed. Omega, now fearing for his life, swallows his pride and pleads for mercy, but Goku refuses to listen and hits him with the Spirit Bomb, destroying him. After the explosion, the others find Goku lying unconscious with the Dragon Balls scattered around him. Suddenly, the Dragon Balls activate on their own and the original Shenron himself appears.
Episode 64 Until We Meet Again: Shenron heals Goku, and explains that he can't allow everyone to overuse the Dragon Balls again, so he is leaving the Earth, and taking the balls with him, planning to return when the people of Earth learn to solve their own problems without using the balls. However, he allows one more wish at Goku's request, which is to repair all damage done to the Earth since the gateway to Hell was opened up by Android 17, as well as revive all the innocent people who have been killed. Just before Shenron leaves, he calls for Goku to accompany him. Goku entrusts Vegeta to take his place as Earth's savior, and as they fly away, Bulma reminisces about her time with Goku. Unexpectedly, Pan finds Goku's clothes on the ground, and Vegeta tells her to treasure them dearly before he and the other Z-warriors leave. Goku stops by Kame House to say goodbye to Master Roshi and Krillin, who has been revived. He also stops in hell to say goodbye to Piccolo, and tells him that he will one day get back into Heaven. As he lies on the back of Shenron, the seven Dragon Balls become one with Goku's body, and he becomes one with Shenron as Shenron finally vanishes. 100 years later, all of the Z-warriors have passed away of old age except for Pan, Vegeta Jr., Vegeta's descendant, and Goku Jr., Goku's descendant and Pan's grandson, are fighting in the junior division championship match at the World Martial Arts Tournament. Goku Jr. is wearing Goku's clothes that Pan picked up many years ago. Pan looks down and sees the now-adult Goku watching the fight, but when she goes down to find him, he's not there anymore; Pan merely assumes that she was imagining things. As Goku exits the stadium, he flashes back to many of the events that shaped his past, from his adoption by Grandpa Gohan to Baby's defeat. With his Power Pole in hand, Goku flies off on the Flying Nimbus into the distance and says "Til we meet again, guys."
