Nappa and Raditz: a survival story

Cover stolen from Chotiphut

This is the synopsis of a plot I'll be working on for me to refer back to, or if I'm unable to complete the story, it'll be a way to eternalize my work. I will write the entire story in a google document then copy paste the whole thing. It will be seperated into three books-
Dragon ball z (sayian saga)
Dragon ball z (Cell saga and buu saga(not many differences for buu saga)
And dragon ball super.

Essentially this is if piccolo's special beam cannon kills Goku but not Raditz and vegeta's attack blows Nappa away instead of killing him.
