bardock and his family(gine and raditz) come to earth with baby goku (gohans this here and he helps them adujst to earth) while not knowing vegeta(5 years old) comes the earth at the same time as well but he meets a four year old bulma and bulma decides that her family will take care of him untill they find his parents. Bulma will still meet goku when he is 12 and her 16 but vegeta will be with her in search of the dragonballs and vice versa to goku with bardock gine and raditz. I wonder scenarios would happen in this took place instead of dragonball.
