After the defeat of the super goku budokai saiyan fight and Future Cell, Future Trunks enters the World Martial Arts Tournament. He meets Future Kibito and the Future Supreme Kai, who inform him of Future Babidi's plan to resurrect Future Majin Buu with the help of his henchman Future Dabura. During their match, Future Kibito asks Future Trunks to turn Saiyan, which lures Future Dabura into stealing his energy for the Majin Buu Resurrection. Against Future Supreme Kai's will, Future Trunks pursues Future Dabura and fights him: If he fails to defeat Future Dabura, one of Future Dabura's Ki Blasts mortally wounds Future Kibito when the latter takes the terrible blast with his own body to protect Future Trunks. Though Future Kibito saved him from one blast, another comes shortly thereafter and hits Future Trunks. With no means of healing him, they have to resort to medical treatment. Meanwhile, with no one to oppose them, Future Babidi and Future Dabura gather enough energy to resurrected Future Majin Buu, who kills Future Dabura in short order and soon, where at first he was heeded by Buu, Future Babidi himself is killed as well. With no orders, Future Buu simply goes on destroying, purely for innocent fun. Though injured, Future Trunks is the only one who can face Future Majin Buu. Future Buu kills him in a battle. With the death of Future Trunks, the fate of the world is sealed: Future Buu destroys the world, and then the universe, then he turns to the Kais. Those who could have stopped Buu were long gone, the world will soon return to nothingness. The action is identical, offering straightforward, one-on-one fighting. The cast offers little in the way of surprises, featuring most of the major heroes and villains from the Frieza Saga on through to Dragon GT, many of whom come in multiple forms. There are a good number of fighters to choose from, but there's not much of an attempt to balance them, with some fighters simply being rated as more powerful than others. There are plenty of signature dragon touches to the gameplay, with a heavy focus on ridiculously potent energy attacks, most of which are unique to each fighter. Aside from their different power levels and special attacks, though, every fighter in super goku budokai saiyan fight handles identically, so once you've mastered one fighter, there's not a lot left to learn.
