Goku: The main character of the series. Goku's father was Gohan, who obviously knew some martial arts. After his death Goku had to fend for himself and eventually met Bulma. They collected the dragonballs and stuff. When Goku was about 5 he met ChiChi his future wife. He ran into her again when he was about 14-16 and they got together. They soon had a son named Gohan, named after Goku's fake father. Bardock was Goku's real dad but he never knew. Goku led many battles. He sacraficed himself to defeat Raditz and was then trained by King Kai. Then when he came back he defeated Nappa and Vegeta. Soon Goku travels to Namek and faces off against the Ginu Force and Frieza. Peace lasted till Frieza returned but Frieza was defeated by Trunks. Then the Androids arrived. Goku had to fight off a heart disease and didnt fight Androids 16.17. and 18. But he was better in time to fight Cell. However Goku again sacrafices himself to defeat Cell. However Cell returns and Gohan defeats him. Goku remains dead but comes to visit Earth which is when Buu arrives. Goku ends up fighting Vegeta but also fuses with him to become Vegeto. Later in the saga Goku becomes SSJ3 and defeats Buu.
The Good Guys
Gohan- At the beginning of the series Gohan is like 3 years old. When Raditz comes to the planet Gohan was afraid for his fathers life, cause he was kept in Raditz's ship. When Goku was being beaten up Gohan got pissed and powered up, getting out and ramming Raditz. Thanks in part to Gohan, Raditz was defeated, but it took Goku's life to do it. Gohan was trained by Piccolo to prepare for the arrival of Nappa and Vegeta. When they arrive they struggle with Nappa until Goku arrives from being trained in the other world. Gohan plays no big part in this other then the fact he was a little chicken. Next they all go to Namek while Goku recovers. Krillin, Gohan and Bulma are first. They try to gather the dragonballs but Vegeta appears, and to their surprise teams up with them. Guru gives Gohan some boosted power during this dragonball hunt. Several fights with the Ginyu Force breaks out. Goku saves them from many of these. When the fight with Frieza breaks out Gohan only fights when Goku goes missing for acouple episodes, then he is teleported back to Earth. When Frieza comes back, Trunks takes him on easily....how disappointing. Now the Androids appear. Gohan plays a small part if I remember right. Now to the Cell Saga. During this Gohan fights Cell toward the end. When Cell crushes Android 16's head Gohan becomes furious and turns SSJ2. The 2 then do a huge kamehameha fight but Cell is overpowered in the end. When Buu emerges Gohan tries to fight him, however is almost killed. Supreme Kai trains Gohan but it becomes pointless and Goku ends up doing all the work....
