Planet Vegeta is about to explode Bardock sends his youngest son Kakarot away to a planet called Earth in an attempt to save the child's life wanting to stand fight for his planet but his wife Gine convinced him to escape luckily they go unnoticed eventually ending up on the planet yardrat they live here in peace for about two years before deciding to go look for Kakarot sadly crashing on planet Namek living there for over 20 years eventually they ended up having another son Bardock Jr at this point in time he was only 6 years old but had incredible strength and intelligence once again they went looking for Kakarot but surprisingly finding their first born son Raditz Bardock begins to explain everything to Raditz happy to see his family again Raditz goes on to explain he too was looking for Kakarot
meanwhile on Earth
The now grown up Kakarot is now going by the name Goku he now has a wife and son of his own Chi-Chi and Gohan Goku is on his way to his former master's house for a small reunion bringing his wife and son every one was surprised to see Goku with a son but Goku just smiled and said
"I'm a little surprised myself but I'm happy"
as Goku's family approach his position he tells everyone to go inside the house as he can feel the energy and it is quite powerful everyone shows up happy to see the long lost Kakarot Goku doesn't know who this "Kakarot" is Raditz seeing how his brother remembers nothing explains everything about them being family Goku doesn't believe this until Raditz points at Bardock and Bardock Jr telling Kakarot that those two look just like him Goku than smiles and explains everything that happened to him except about his kid finally saying "well if we are family you need to be introduced to two people" Goku goes inside the house and comes back out with Chi-Chi and Gohan Gine seeing the young child finally speaks up "who's that"
"my wife Chi-Chi and son Gohan"
Bardock has a small smile and says "she is a beautiful young woman and the half saiyan hybrid is full of hidden potential"
Chi-Chi is happy for the compliment but is also a little angry and shouts
"Gohan will study and become a great teacher or something he's not going to fight" Bardock a little frightened replies
"I see why you picked her to be your wife Kakarot but Chi-Chi I can assure you he needs to train there are two more saiyans on there way here and will be here in about a year they are the former squad of Raditz we need all the help we can get and Gine is fairly smart and can teach the boy what she knows this planet is in danger" Chi-Chi getting angry says "Goddammit I hate to say this but if the planet is in danger you can train him but Goku you need to make him strong enough" "I will Chi-Chi but dad what do you mean that you can see why I picked her" Goku responded Bardock looking a little nervous says "All saiyan females are strong and have a bit of sas to them this is what draws the males to them" "Oh that makes sense I first fell in love when I saw her fight in a word torment" Goku says happily Chi-Chi smiles and blushes
"Alright back to the matter at hand Vegeta and Nappa are on their way here because I may have abandoned them we need your help brother we need to train" Raditz said
one year later
After one year of training every one has grown closer as a family Gine grows close to Chi-Chi and Bardock Jr has a very good friendship with Gohan both being close in age eventually Vegeta and Nappa arrive in a wasteland and the team goes to fight
when the fighting starts there are some casualties Nappa getting pissed that this is taking forever fires an energy blast at Gohan Krillin jumps in the way and is greatly hurt Goku runs over to his best friend's side holding him as he dies Goku is now staring at a lifeless body twitching in anger his hair stands up and turns golden he lets out an angry scream and charges Nappa punching a hole in his chest killing him instantly "Holy shit" Vegeta shouts Goku still in a blind rage beats the crap out of Vegeta knocking him out Goku then passes out when he wakes up he is in the hospital Bardock explains what happened and how Vegeta is still alive but being watched over by Raditz
Goku is shocked to find out that he he killed Nappa and even became the super saiyan of legend he is also sad because his best friend is dead for the second time Bardock explained the dragonballs on Namek and the three wishes you get with them "Three wishes we only get one and Krillin already died once we can't wish for the same thing twice" Goku says Bardock is shocked to find out about the Earth's dragonballs "We need a ship to take us to Namek but first rest up son I'm proud of you I will Speak with Vegeta and see if he will help us take on the evil emperor Frieza and avenge our people"
