Having defeated Boo, Goku is starting to get bored with his life on Earth. His wife, Chi-chi, wants him to get a job, but all he wants to do is train and fight stronger enemies. Elsewhere in the universe, the God of Destruction, Beerus, and his attendant Whis are traveling from planet to planet in search of food and entertainment. After blowing up some hapless victims, Beerus is reminded of a man from his dreams with the moniker “Super Saiyan God,” or something like that. The God of Destruction sets his sights on Earth to track down this mysterious man! Maybe this will give Goku something to do?

The anime and manga are both based on an outline by Akira Toriyama and differ greatly. The Galactic Patrol Prisoner and Granolah the Survivor Sagas are manga original, set after Broly. Resurrection F & Broly happen off-screen. Super Hero is extended through prequel and epilogue stories.
