Universal Spirit Bomb

Universal Spirit Bomb (全世界の元気玉) is the final and most powerful version of the Spirit Bomb used by Goku. It draws its phenomenal power from energy sources across the entire universe. It was used as a final attack to defeat Omega Shenron.

History
After Goku and Vegeta lose both their fusion into Gogeta as well as their Super Saiyan 4 transformations, the battle against Omega Shenron seems hopeless. However, as Omega is about to kill the Z Fighters, Goku, who is thought to have been killed while trying to stop an energy ball from destroying the Earth, rises up from a crater and prepares the Spirit Bomb with all the energy from the people on Earth. Even so, it is still not powerful enough to defeat Omega Shenron.

However, thanks to the help of King Kai, along with the other Kais, Goku is able to ask every person in the universe to donate their energy to the Spirit Bomb, thus creating the Universal Spirit Bomb. With the attack complete, Goku launches the Universal Spirit Bomb against Omega Shenron, completely destroying the Shadow Dragon and moving it upward into the sky where it finally bursts into a massive, black explosion. With all of the Shadow Dragons finally defeated, the Dragon Balls are restored to their normal states.

This technique is named Super Ultra Spirit Bomb (超ウルトラ元気玉, Chou Urutora Genki Dama) in the original version of the sixty-third episode of Dragon Ball GT and in the Dragon Ball GT Perfect File volume 2.
