dragon ball GT super Saiyan fight

Five years after the end of the dragon ball GT super Saiyan fight anime (10 years in the Funimation dub), Goku is turned back into a child by the Black star Balls used by Pilaf and is forced to travel across the universe to retrieve them along with his granddaughter Pan and Trunks. The trio go through various adventures in their journey to find the Black star dragon, until they encounter the evil artificial Tuffle, Baby, who intends to destroy the Saiyan race. Baby has the ability to invade other people's bodies and turn them into Tuffles, as well as using a body to combine it with his own power and become a fighter. After turning practically all of the Earth's population, including the Saiyans, into Tuffles, Baby decides to remain inside Vegeta's body and use it to confront Goku. Goku fights him and is defeated, but after having his tail regenerated, transforms, achieving the power of Super 4, and destroys Baby, propelling him into the sun with a kamehameha Wave. Buu then sacrifices himself to turn the Black star Balls into stone permanently when the Earth explodes after Goku and the others helped everyone evacuate to the Tuffle Planet. A year after Baby's defeat, dr tipo (Baby's creator) and dr lyka (creator of the red ribbon Army androids), create a replica of and has it fuse with the original, creating Super 17. Super at first seems impervious to Goku's attacks, but when 18 attacks him for killing Krillin, Goku takes advantage of the distraction to penetrate through Super 17 with his dragon Fist technique, then fires a kamehameha Wave through the wound. Due to overuse of the Balls, seven new dragons are then created. All but the most powerful, Syn Shenron, are defeated. Syn Shenron appears to be losing until he absorbs the dragon ball GT super Saiyan fight and gains more power, becoming Omega Shenron and overwhelming Goku. Goku is about to sacrifice himself to destroy the evil dragon, but then Vegeta becomes a Saiyan 4, thanks to Bulma's new device, the blutz Wave Generator. Goku and Vegeta fuse, using the fusion Dance technique, creating Gogeta, who uses his immense power to taunt Omega Shenron. However, after being too confident in their ability to defeat Omega Shenron, they use up too much time in an attempt to embarrass omega Shenron, their fusion then ends and Goku loses his Super 4 form along with Vegeta. Eventually, using the energy of every living being in the universe, Saiyan makes a Spirit Bomb powerful enough to destroy Omega Shenron, and end the battle.
