A martial arts champion
Goku is the hero of one of the most famous manga and anime Dragon Ball Z. In the first part of the manga, he is a child and shows a particular talent for martial arts. He will therefore be trained and find himself fighting very powerful villains despite his young age. In the second part of the manga, Goku is older, married and has a child with Chi Chi. Then he learns that he is in fact one of the last representatives of an extra-terrestrial race of super warriors. He then finds himself fighting much more powerful enemies but also developing his own strength and abilities much higher than those of a human.
