How do you think the Buu Saga would have played out if Goku hadn't returned—if his death had been truly permanent? (no communicate or anything)
I read that at the beginning of the Buu saga, during Gohan's time at school, Toriyama was testing Gohan as the protagonist. So, what would Dragon Ball be like if he had followed through with that? Goku doesn't return, and Gohan remains the main character.
