Dragon Ball Z: Fusion Reborn (English Audio) HOT!
Now in Super Saiyan 4 form, Gogeta was easily able to fight the united Shadow Dragon, even toying with Omega Shenron and eventually taunted him to the point that he used his Negative Karma Ball to try and destroy Earth. Gogeta combined the ball with some of his own positive energy as he kicked it away into the atmosphere, causing the entire ball to change into positive energy. It resulted in a nuke-sized explosion, which reversed all the negative effects the Shadow Dragons had caused to the Earth. Eventually Gogeta blasted Omega Shenron with his Big Bang Kamehameha, forcing him to revert back to Syn Shenron. But as he prepared to finish the Shadow Dragon off with another attack, the fusion time ran out early (it only had been 10 minutes or 15 at the most). This was because of the enormous amount of power the Super Saiyan 4 form used and Goku and Vegeta defused, though Goku was able to destroy Omega Shenron later on with his Universal Spirit Bomb.
