Vegeta

Vegeta (ベジータ), or Prince Vegeta, is the prince of the fallen Saiyan race and arch-rival to Goku. He is the eldest son of King Vegeta, the older brother of Tarble, the husband of Bulma, the father of Trunks and Bulla, and the great-great grandfather of Vegeta Jr. Alongside Goku, Gohan, and Piccolo, he is easily one of the most prominent characters in the series, receiving more character development after being introduced than a number of other characters.

Regal, egotistical and full of pride, Vegeta was once a ruthless, cold-blooded warrior and outright killer,[6] but later abandons his role in the planet trade, instead opting to remain and live on Earth, fighting alongside the Z Fighters; all the while striving to become the universe's most powerful warrior, specifically with the mission to defeat and surpass Goku in power.[7] His character evolves from villain, to anti-hero to protagonist through the course of the series.
