How does Vegeta come back from the dead?
In FUSION REBORN, the 12th Dragonball Z movie, Vegeta comes back to life by a accidental ramication in OtherWorld when all the villians Goku faced and a new one named Janemba (Janempa in the first form). In the show, Vegeta comes back because Kai sacrifices his life to give to Vegeta so he could fuse with Goku by using the mystical Potarra Earrings.
