Disclaimer: I don't own Dragon Ball Z, but I love it :D
After Cell dies when Vegeta is neutral (not evil, not good), his spirit leaves his body & time, and will possess the body of his younger days; when he arrives on Earth with Nappa to obtain the Dragon Balls. How will it affect him, now that he is not the guy that he used to be? Can he withstand seeing Nappa killing everyone? From Vegeta's point of view. Lots of action, adventure, drama, and DBZ comedy.
Prologue
Earth. Yes, the planet I've longed to see after a few weeks of intense training in space, still can't be over Kakarot's death that occurred a month ago. Something triggered inside me when his wish of staying dead reached my ears. Why? I wonder. Now I am the only full-blooded Saiyan left in the entire universe. I have no goal anymore, no will. As much as I hate to admit that I am feeling affectionate to my family now, it still won't be enough for me; I need something more to look forward to. I need Kakarot, I thought angrily. I need him in my life again, as it is completely empty without him. I also regret that I killed Nappa, the one who practically raised me after Frieza's enslaving.
Now I am on Earth again, but not how I quite imagined it would be; I heard Nappa's voice earlier before I landed here. It can't be possible; I killed him five years ago. I'm surprised, but also relieved to hear his voice again. After the death of my son, Trunks, by the hands of Cell, I began to start caring more about the ones I am used to. Nappa was like a second father to me, so how in the world did I get so angry at him to kill him? I loathe heroes like Kakarot, but the fact that regret haunted me for this, I am thankful to see Nappa again.
To make matters complicated, I am in my younger body. I was a ruthless killer five years ago, something different from what I am now. Of course, I will never turn into a hero like that sissy, Kakarot. However, here I'm standing now; people frightened of me, in the big city that me and Nappa destroyed five years ago without hesitation. Now I pity the humans, not care, but feel like it isn't necessary to kill them all off like I did five years ago. I don't want to dirty my hands that easily.
However, that doesn't change the fact that I am still me and that won't change. I want the Dragon Balls for my own desire; to wish myself back to my world after I've killed Frieza; there is no return there, as I'm not even sure why and how I'm back into my younger body. Hell, I don't even desire to turn into an immortal now, even though I've been to Hell when Frieza killed me on Namek. I'm fully aware that I'm stuck in my younger body, which means that my powers are limited compared to my own dimension's. However, I have to be careful not to act recklessly like I did five years ago; if I'd end up dead again by Frieza, means that Kakarot will defeat Frieza here too, and I won't be able to overcome the anger that built inside of me, just how I was humiliated in the after life, five years ago, by my own father. No more, Kakarot, you will never be able to defeat Frieza here! Maybe it was truly my destiny to kill Frieza? How else would I mysteriously end up here?
It will be me to avenge my people, and not the circus clown pathetic excuse for a Saiyan who is more proud to be a human than a Saiyan. It shall be my destiny to kill Frieza. I didn't succeed in my own time-line, but it will be different here. I have to be the one to slaughter him painfully slow. I don't care how it will affect the future, as long as some stuff happens: Frieza to die by my hands, gaining Super Saiyan before Kakarot, and Trunks has to be born. If I had the strength, I would have wished for my planet back and its people, but I don't. Therefore, first things first, I have to gain immortality and defeat Frieza, what I originally intended to do five years ago. What use will it be to restore my home planet if Frieza will destroy it again?
Knowing that the human fools recently used the Earth's Dragon Balls to wish Kakarot back to life, the balls are useless for a whole year. I have to go to planet Namek, alone. I can't bring Nappa with me; it isn't his destiny to go there. If only I can make him leave for another mission when I am on my way there, later.
First, I have to get stronger, as much as possible, by fighting Kakarot. This time I won't let those runts cut off my tail. I remember their tricks and that clown's kaio-ken attack. I won't turn into the giant ape this time; I need a lot of beatings from them. This way, I won't lose my tail and will get stronger when I recover. That idiot, Kakarot, will let me go anyway, I thought.
This time, Kakarot, is my turn.
Vegeta will talk big now, but once fate confronts him when he sees Nappa killing his "future friends", it would make things complicated for the Saiyan prince. He's stuck in-between being good and evil. So, what do you guys think?
The prologue contains Vegeta's true feelings of what he felt when he was living in the past as a brutal killer. Mixed emotions confused him. Saiyan Saga part 1 (chapter 2) is the beginning.
Vegeta isn't evil enough to be the heartless monster that he once was, but Vegeta is not the hero, because he isn't good enough to be one; he becomes a good guy after Majin Buu Saga and that's actually in 7 years from Vegeta's original time-line (Cell Saga). Sorry if you good-Vegeta fans are disappointed.
This story is not about Vegeta replacing Goku. It's about Vegeta living his old existence again as an anti-hero (who wants to kill Frieza himself) that the death of future Trunks and Goku in his time-line somewhat softened his heart. The main genre is Adventure/Drama, so expect a lot of dramatic guilt through the prince's point of view.
