Vegeta (Amnesia)

Vegeta:

Vegeta History: As the first major antagonist of Dragon Ball Z, Vegeta is the prince of an elite extraterrestrial warrior race known as the Saiyans. As a person, he is naturally blunt, regal, hard-working and is full of his saiyan pride; he often refers to his heritage and royal status throughout the series, but can also have negative traits such as being extremely haughty along with a destructive temper. He believed that he should be regarded as the strongest fighter in the universe, and becomes obsessed with surpassing Son Goku after losing his battle with the Z fighters. However, after Frieza's death, Vegeta unites with the heroes to thwart greater threats to the universe, most notably Cell, Majin Buu, Beerus, Zamasu, Jiren, Broly, Moro and Granolah. Throughout the series, Vegeta's role changes from villain to later as one of the heroes, while remaining a key rival to Goku.
