Gohan
Gohan is one of the main characters probably because he is Goku’s son. He starts out as a Saiy-jin  kid who isn’t very
powerful. As he goes along in the fights he becomes stronger, like all Saiy-jins would.  His mom Chi-Chi has vowed to make him a
scholar so any free time he has he is studying. Throughout all the episodes he takes after his father and is nice guy.
Family
          Gohan’s mom and dad are Goku and Chi-Chi. He has a brother named Goten. Later in the show he marries
Videl and has a daughter, Pan, the strongest girl in Dragonball

power up by Guru and brings out his real spirit on Frieza after he is appeared to be killed. In the Cell saga he trains
with Goku in the Hyperbolic Time Chamber. That is where he goes Super Saiy-jin for the first time. In the Cell game he
