brief history:: Gohan, named after Goku's adopted grandfather, is the first child of Goku and Chi Chi. After birth he become mama little boy, and because of his mother's rules he never able to show his real potenial as a Saiyin child. Gohan was always more interested in his studies rather than his fighting potenial. However, after his father's first death he is forced to train under Piccolo, who soon after becomes like a second father to him. Gohan is thought to be ever stronger than his father but never really proves it. However, he was the second to reach Super Saiyan at the age of 9. As the years go by he would become the Super Hero Saiyanman, where he runs into Videl.

brief history:: This is probably confusing to all of you who haven't watched anything but the American Dragon Ball, but there was a point in time that Trunks, known as Future Trunks, traveled back in time to give Goku medication to save him from his heart diease. Because the world that Trunks grew up in was overun by the bad guys. Trunks travels back in time and becomes one the most important characters to the storyline, as well as one of Toriyama's favorites. During this time Trunks does a heavy amount of trainning and achieves a very high power level, maybe even higher than Goku's. Trunks goes back to his time and Chibi Trunks emurges. Chibi Trunks is more like his father, because he never learned his manners like the other Trunks did. When Goten and Trunks get a little older they are able to form Gotunks. Goten and Trunks are the best one friends, they both were able to reach SSJ at a young age. I find that they make the story funny again like in DB.
