Goku tells everybody the truth.

Goku: Actually, I am a reincarnated person from an other universe.

In my world you a just an anime.

After I died saving a child,

I heard somebody saying "You like the dragon ball world right? Go there" he chanted it like a mantra.

And I have watched this series a lot even know what enemies are going to come next I know some of the next enemies that is why I train.

Z-Fighters and Goku's family: What!!!!

Goku: I am sorry can you forgive me?

Z-Fighters and Goku's family: No! You have hided it from us for so long!

Narrator: After some time of convincing he told the details,

Goku: My real name is Gink And I am also from earth in my universe, I was reincarnated into Goku when he was a kid.

And I had to act like him for Gohan, trunks and Goten to be born I wouldn't want to be the one to erase Gohan, trunks and Goten out of existence.

Z-Fighters and Goku's family: What!!!!! alright but why didn't you tell us sooner.

Goku: Well I was scared that you all will never speak to me again. ( He was not an adult when he came here).

Z-Fighters and Goku's family: Hmm... we would have just forgiven you, except for Vegeta I think?

Vegeta: Kakarot!! all this time you could have easily surpassed me. Damn!!!!

Goku: Vegeta I know you are angry but I want you to learn Super Saiyan 3 before Buu gets released or we can stop him from getting released.

Vegeta: Who is this Buu?

Goku: He is a Majin created by a evil magician even Super Saiyan 2 isn't enough to stop him But Super Saiyan 3 is enough I think.

Z-Fighters and Goku's family: Super Saiyan 3!!!!

Goku: Yeah Super Saiyan 3 even I can access it now but Super Saiyan god is on an whole other level. Goku Thinking "In these shocking events can make them listen to me).

Come with me.

(they go out.)

Everybody grab on to each other.

(Shwoooom)

(Goku teleports everyone to a uninhabited place on earth.)

Oh and by the way Goku's power level will be revealed in the next chapter.
