This is the prologue to the main story, so don't get all mad and stuff. Also, I am making it so Pan is 15 and Roku is 10 in the actual story.
Disclaimer: I don't own DBZ
Prologue
Less than 3 months after Goku left to train with Uub, a child was born. He had black spiky hair, tan skin, and a brown furry tail. His name is Roku Briefs, son of Vegeta and Bulma. Vegeta detested his name being so close to 'Goku', but Bulma appeased him by making his middle name Vegeta.
He is 4 years younger than Bulla, and 18 years younger than Trunks. At the age of 3, Roku started playing with Pan. (Who was 5 years older.) Roku was naïve, innocent, and fought simply for fun and to please his father. In short, he was nothing like his father or his mother, except for the fact that he was more stubborn than Bulma, Vegeta, and even Trunks combined. (So basically, imagine the most stubborn person you know. Now times that times a hundred, now times THAT times a thousand, and you've got a pretty good idea of how stubborn he can be.)
At the simple age of five, he had become a Super Saiyan, as he had been training for months. Then, an even greater surprise when, three years later, he had become the youngest Super Saiyan 2 ever in history.
Of course, he had Vegeta's blood, had massive potential, he became enraged easily, and Vegeta was a Super Saiyan 2 when he was born, it was still a big shock that he was 8.
And he, of course, wasn't able to transform at will until the age of 9, and even though he could still transform at will, it still sapped him a lot to transform.
Now, we bring you to one week before the day that changed the lives of the entire Z-gang, forever…
Remember, this was a prologue, so it's kinda' short, but all of the other chapters shall be longer. Please review!
