Prologue: My Ending

Everyone calls me Goku Black now, as I do look like Goku.

However, my real name is Zamasu, and my true identity was a Kaio shin, the god of creation of universe 10.

My long goal is to eradicate every single mortal in this world. The only being that should exist are gods just like me. Unlike any gods, I would only allow gods that cannot intervene with my plans to live. The rest of the gods that has the potential to stand in my way...

Are ALL DEAD.

Because I killed them all, for they would never agree and understand my true intention.

These gods are includes every single Kaio shin from every single universes as well as the gods of destructions.

And that meant my master - Gowasu - has to die too...

Long after I switched body with Son Goku...

Long after I formed an alliance with my future counterpart...

Long after the distorted and confusing timeline was created...

My plan of exterminating every single mortal had been interrupted by an even more powerful being...

My plan was destroyed by Zeno sama, also known as the king of everything. The creator and destroyer of all gods and human beings. The true ruler of every single universe.

In the future timeline, I traveled to, the Earth had been destroyed by Zeno sama. The destruction wave he unleashed destroyed my future counterpart, erasing him from existence. At least Zeno sama had accomplished and completed something I haven't completely finish - destroying mortals on the planet.

Little did I know he would destroy my future counterpart's infinite form as well, and with such ease.

The Infinite Zamasu appears as an endless number of my original kaio shin face in the sky. The green faces of the Infinite Zamasu turned into more of a moss green faces, and the countless numbers of white eyes shining and glaring into the earth just like lethal stars. The laughter in the skies echoed through the entire planet.

It would seem like the entire planet was covered up by the Infinite Zamasu.

Interesting, isn't it? Back when I fought against Goku and Vegeta from the present timeline along with Trunks from the future timeline, my body - Goku's body - had fused with my future counterpart - the original Kaio shin with the green face. Merging into an even more powerful being. With the shining silver hair of a Saiyan and the face and wisdom of a God of creation.

In the end, my merged body was sliced into half by the sword of a mortal. Although I was immortal, I still felt pain.

Perhaps it is because the body of a Saiyan would never become immortal, unlike my future self. The body of a mortal would never fully be invincible, even if you wished for it with the Dragon Balls.

More importantly, that attack by the sword that pierced my body had separated me from my future counterpart. A miracle, I would say, that I would not have to share the same fate as my future counterpart - being erased by Zeno sama. But till now, I still don't understand how we managed to separate into 2 beings again.

Once 2 gods merge, it is classified as impossible to separate into 2 gods again. Once the fusion is complete, you cannot undo it.

But deep within me, I felt relieved as well as lucky...

Because even though my counterpart was erased from existence, I could move my body freely once again. Unlike the Infinite Zamasu that cannot move at will.

And by doing so, I survived the tremendous attack of Zeno sama.

For I used the "Instant Transmission" technique to teleport me to a different place. And that is all thanks to Son Goku's body, and thanks to myself who switched bodies with him in the beginning.

Now...

I have 2 goals...

Eliminating every single mortal...

And my sweet revenge against those wretched Saiyans.

And you may guess what is even better?

No one, not even the king of everything can stop me now. Zeno sama was the most powerful king in space, but he was also a foolish child. Now that he destroyed Earth for me, he has no grounds to stand on. He would just be floating in the middle of the universe, with no one to help out with.

However, it wasn't long until I realized that my strength had drastically dropped down. Perhaps Trunks' sword attack that pierced my merged body in half did do some colossal damage to my switched body.

It would be a while until I fully recover from my wounds and regain my strength again.

After using the Instant Transmission skill, I arrived at a different planet.

I assume it's another star not far away from earth.

Where... am I...?

I thought to myself, breathing heavily as my wound spiked on my body.

Forget it... I won't last for much time now...

Slowly yet insecurely, I landed on the ground. While leaning on one of the solid rocks, I slowly fell into unconsciousness.

It's... not... over yet... with my last thoughts, I fell into the peaceful darkness.

This is all made up. I never wished Goku Black to die so pathetically. A bit short, because it's the intro. But if some of you don't like it, I will try my best to update it with more details.

The timeline is very confusing too. In short...

Goku Black is Zamasu (Zamasu from the present world which Goku lives in, used the time ring to travel time)

Future Counterpart is also Zamasu (Zamasu from the future)

And you could guess future Trunks (Future)

And Goku and Vegeta (Present)

Have a nice day.
