Gohan is a son to Goku and Chi Chi, brother to Goten, father to Pan, husband to Videl. When Gohan was young he was a schoolboy with a normal life until Goku's brother Raditz tryed to invade planet Earth. As this happened Gohan was held prisoner in Raditz pod while his dad Goku and Piccolo were fighting Raditz. Goku as usual was getting beat up big time until Gohan's anger overcomed him when he heard the screams of pain from his dad. Gohan exploded with power and hit Raditz with a blow to his ribs. From that point on Gohan has been training and fighting in battles, getting stronger and stronger. Gohan, around the age of 12 in the Cell Saga, became the most powerful fighter because of his achivement in becoming Super Sayajin 2. Gohan had only reached 2 Super Sayajin stages and one Special stage titled "Mystic Gohan". This stage is equivalent to SSJ3 but isn't in a Super Sayajin form only a plain Sayajin. If he ever turned Super Sayajin his power would be so great it would destroy the Earth. He was given this power after he broke the Z sword that incased Dai-Kaioshin. Dai-Kaioshin in return awarded Gohan with this power. But as years past to the GT series he started to decrease in strength because he starts to study again (which is one of the reasons i don't like GT). Oh yeah before I forget there is a part in DBZ where he becomes "The Great Saiyaman" and danced cocky like Ginyu! Well there are the important facts on Gohan!
