Son Gohan:

Son Gohan is Son Gokou's first son named in honor of Gokou's late Grandfather. He turns out to be one of the most powerful warriors in Dragon Ball Z due to the fact that he can turn his anger into pure power. He is actaully the strongest when he is younger because he has an uncontrolable temper. This power enabled him to become the first Super Saiyajin Level 2. As well, he was extremely inteligent when he was young because his mother, Chi Chi, constantly urged him to study harder. He still remains powerful when he is older only because the Kaiohshin (gods) give him increased power with a Kaio Upgrade to defend Earth with, but he never truly develops his full potential and power. Without the Kaio Upgrade, Gohan would have become one of the weaker fighters because he doesn't continue his training as he gets older. As an adult he marries a human girl he meets in High School, Videl. With Videl he has 1 fourth Saiyajin daughter...Pan.
