We all know that Frieza came to Planet Namek in search of the Dragon Balls to make his wish for immortality, but was ultimately stopped by Goku and the rest of the Z fighters, but, what if Frieza actually got his wish for immortality? What if instead the Z fighters weren't able to stop him and instead Frieza destroyed Planet Namek and continued off to conquer the galaxy? For extended plot, let's go ahead and say that Goku was still more powerful than him in SSJ1, but ultimately wasn't able to permanently take down Frieza due to his immortality. Let's say that Mecha-Frieza was never created then. How would that affect the story? How would that, in part, affect other DBZ villains like Cell and Buu who are arguably more powerful than Frieza? Would they be able to take down and defeat Frieza? Say Frieza isn't powerful enough to take them down, but his immortality prevents him from dying. What would happen to the DBZ story then? If everyone was more powerful than Frieza, but no one could ultimately kill Frieza due to his immortality, how would the DBZ story change? What are your thoughts on this?
