Son Goku

Son Goku (孫 悟空, Son Gokū? Born Kakarot （カカロット, Kakarotto）) is the main protagonist of the metaseries Dragon Ball.

Born a Saiyan on Planet Vegeta, Goku was sent to Earth to destroy it at a very young age. Upon his arrival, he was found and then raised by his adoptive father, Gohan. When one day he hit his head against a rock and lost his barbaric Saiyan nature, he continued living his life along Grandpa Gohan, eventually growing into a simple-minded, yet kind hearted savior of the planet he was once sent to destroy.

Power and Abilities
Goku is arguably one of the most powerful characters ever created. In his own world, and on a universal scale. As a Saiyan, he is naturally born stronger than average humans by many folds, and with his never dying lust for power, Goku trained relentlessly to become as powerful as he can be. To further extend his power, Goku can tap into his inner strength by transforming into a Super Saiyan, a Saiyan exclusive form which changes his outer appearance and multiplies his power and speed by up to 50 times his normal state. He later develops more Super Saiyan stages and eventually steps into the realm of gods by unlocking the long lost Super Saiyan God form.
