Hello this is a Dbz fanficiton.

I don´t own Dragon Ball Z or Dragon Ball super

It all started when 7 year old Goku killed his grandfather in the Oozaru form. Goku woke up naked and sore, he quickly realized the destruction around him and went looking for grandp Gohan. He found him dead.

Goku: Grandpa!"cried goku "Grandpa, are you okay, c´mon Grandpa this isn´t funny, awke up."

By now Goku was in tears. He screamed.

AHHHHHHHHHHHHHHHH!

And screamed until something snapped inside of him, he realesed a bulue aura towards the sky( imagine path to power on a smaller scalle). Uknown to goku his Ki unlocked that day.

Time-skip (2 days later)

Goku was cleaning the house when he found something on Gohan room. A book. It was the book where Gohan wrote everyday, Goku got curious as to what the book was. It said.

To Goku...

Hello Goku, if you are reading this it means i died. I write in this book because i want you to know the truth about yourself and myself. I love you like a grandson but you are not my grandson by blood i found in the woods you were in a spaceship so i believe you are from space i want you to go there after reading this. I also want you to know that i was once trained by master Roshi the best martial artist in the world. I want you to look under by bed there is a door open it and look through it and you will find weights and documents on technics like the kamehameha and the turtle hermit style of fighting. I want you to know that i love you so much and i couldn´t of asked for a better grandson.

By the end Goku was in tears, but if you looke deep in his eyes you would see determanation to be the best.

Goku:" I will do it grandpa and i will become a man that you are proud of" said Goku to himself.

Scene change (spaceship location)

So this is it thought goku. He finaly found the spaceship there he learned everything about what he was, apparently he was from a race called saiyans sent here to destroy the planet(Goku was horrefied by that), his race was under control by a tyrant named Frieza, he also learned of the Oozaru transformation, in which he realized he was the one who killed grandpa, that horrified him and almost brought him to tears, he also saw a bunch of techniques from the saiyans.

Scene change(basement)

Now Goku was in the basement there he saw his grandfathers story and training the weights and the kamehameha technique.

He immidiately straped on some weights and started to clean the house with the weight´s on.

Time skpi( 1 year)

Goku had trained to his limits using saiyan and master Roshi technique and training and he also used his scouter to mesure his strenght, when he started he was at a power level of 30 and now his power level was 300. He had also learned the kamehameha wave, how to fly, how to control his transformation and he eliminated his tail weakness.

Time skip(2 years)

Now goku was 10 years old and was going home with his lunch when he found a strange object heading his way. He dodge it with practiced ease, and the object crashed against a rock,and found out that there was a girl inside( he reade his grandpa books so he is not like canon)with blue hair.

Goku:"Are you ok"

Bulma:"yeah, who are you? My name is Bulma."

Goku:"I´m Son Goku."

Bulma:" are you doing here goku"

Goku:"I live here. And you?"

Bulma:"I´m here in search for the dragonballs"said bulma showing him the dragonball

Goku:"hey that looks exactely like my grandpa ball exept this only has 2 why do you want it"

Bulma:"Because if you gather the 7 dragonballs you can have one wish. And i´m going to wish for the perfect boyfriend."
