I have been watching Dragon ball(its previous series) since I was a kid. I loved dragon ball too much. dragon ball features son gokus adventures with his freinds bulma, oolong, yamcha and krillin. as they follow many adventures during their search for the dragon balls, the seven magical orbs which when collected can grant any wish.
In the last arc the protagonist, son goku defeats a namek, piccolo in the 22nd world martial arts tournament who was the offspring of his old enemy, king piccolo.
Dragon ball Z starts when goku heads to meet his old friends in a reunion with his 4 years old son, gohan. That is when his new journey starts he faces many enemies and makes new friends he is told about the truth that he belongs from a planet in the far space, planet vegeta. and he is galactic warrior, kakarot who was sent on earth to exterminate all the life from this planet. he faces many new challenges and with his friends and family he is able to overcome them all. it features the story of an orphan who fell from the stars, to become the savious of the universe.
