Z itself only repeated plot arcs from #dragonball

E.g. God aka #kamisama fights undercover in the Tenkachi tournament

Goku is trained by Kami to fight e.g. #Piccolo #Daimao

Roshi allies with Tien and Chaotzu to fight Piccolo: repeated when Piccolo Jnr trains Gohan, repeated when Vegeta fights 18/Cell/Dabura

Other than old age death became less serious, although it probably helped make Z suitable for children , this was returned with the concept of Hakai (outside planetary destruction)
