Gohan

Goku and Chi Chi's first son, named after Goku's adoptive grandfather Gohan. In early DBZ, Gohan is put through events that would traumatize any little kid. One day, he's kidnapped by his uncle Raditz, and watches as a furious battle ensues between Goku, Piccolo and his uncle. When Raditz proves his superiority in power, Gohan's anger explodes and he manages to seriously injure Raditz, which neither Goku nor Piccolo had been able to do. After Goku's & Raditz death, Piccolo leaves Gohan in the wilderness to train. Gohan is forced to grow up quickly, he becomes attached to Piccolo, his teacher, and idolizes him. When Gohan's Saiyan power becomes mixed with his human emotions, he is able to summon an unbelievable amount of power. This power is released when Gohan becomes extremely angry. When Cell learns of this he purposely pushes Gohan until he finally explodes with rage and then goes SSJ2, the first person to ever reach this stage. With a broken arm, Gohan kills Cell using a one-handed Kamehameha. Gohan is the only Saiyan to become Mystic, which is a special ability granted by Old Kai that allows Gohan access to his highest power level without having to go Super Saiyan at all. Gohan meets Videl in high school, who suspects that something is fishy about the Great Saiyaman. They become good friends after she catches him in costume without the mask, and he teaches her how to fly. They fall in love, and at the end of DBZ, they have a daughter named Pan. Akira Toriyama originally wanted Gohan to become the main character, of the series, but the fans wanted Goku back, so Toriyama drifted away from Gohan to focus more on his father again. After the Buu Saga, Gohan gives up fighting and finally achieves his mother's dream for him to become a scholar. Throughout GT, he fights from time to time, but he generally remains a glasses-wearing nerd.
