Another creation of Akira Toriyama, Dragonball Z has Goku and Chi Chi. Before Dragonball Z Goku and Chi Chi have a baby named Gohan, the main character in this Dragonball series. Gohan is Goku’s and Chi Chi’s pampered little 4-year-old boy, at the beginning of Dragonball. The story starts off with Goku’s evil brother, Radditz come for Goku to come with him to become a space pirate. Radditz finds out that Goku, as a baby bumped his head and forgot who he was. Then, Goku learns that he’s a Saiyan, and that Goku’s born name is Kakkorot! Radditz gets mad, when Goku got his tail removed, permanently a long time ago, and can’t reach his full Saiyan power, Oozaru, a giant ape form and increases a Saiyan’s power by 10! Goku being a Saiyan this would make Gohan ½ Saiyan. Goku and Gohan go though a lot, you know go though 2 Super Saiyan forms, oh yeah haven’t told you, Saiyans can go though a form could Super Saiyan, but a Saiyan must have a pure heart, there are 3 main Super Saiyan levels(Goku and Vegeta become Super Saiyan Goku 4, and Super Saiyan Vegeta 4, so really SSJ4 ISN'T REAL)
