The Great Saiyan Outburst

Storyline: 5 years after Goku's death
Raditz and multiple other fallen saiyans are coming back to life and attacking innocent people, stronger now. They have been seen transforming into Super saiyans 1,2, and 3. Gohan achieves super saiyan 5 status and defeats Raditz despite the fact that he was his uncle and leaves earth in search for Naikeman, the altered planet to the Namekians. They have their own Dragonballs, and Gohan travels to their universe to find them. He meets a Naikemanian who is searching for dragonballs and decides to wish for all of the fallen warriors to come back to life. Even though Goku didn't like it, he came back to Earth to help. "Gohan, I know that you need me, but If I decided to leave Earth to keep bad guys from going there in the first place, then why did you wish me back?!?!" Goten decided still to bring them back to Earth and they land at where Roshi used to live, what was now an abandoned island with an unused house. There they trained for the onslaught that was upon them...
