Vegeta (ベジータ), or Prince Vegeta, is the prince of the fallen Saiyan race and arch-rival to Goku. He is the husband of Bulma, the father of Trunks and Bulla, the brother of Tarble, and the great-great grandfather of Vegeta Jr. Aside from 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. Vegeta was once a young member of the Saiyan Army under the Planet trade organization, but after his race's demise, he worked alongside Nappa and Raditz, directly under Frieza. He later joins the Z Fighters while battling alongside them on Namek, and returns to Earth with them as well, where he remains for the rest of his life.
