In 1989 Akira Toriyama created Dragon Ball Z. To this day it is arguably the most popular anime of all time spanning hundreds of episodes, multiple series set before and after, and quite the number of movies too. It is regularly described as a gateway into anime for most people who aren't already fans.
Dragon Ball Z follows the story of the main protagonist Goku and his never-ending love for fighting or increasing his power in order to combat the next threat to the Earth. Goku is accompanied by his friends and family who more than often have to stand back in awe as they are completely outclassed by Goku's power.
One former antagonist that heavily rivals Goku for strength and ability is Vegeta, born on the same planet and of the same race, he is one of the few to truly go toe to toe with the Saiyan warrior and survive. Vegeta originally starts out as a villain but has quite the amazing character arc throughout the series.
