Vegeta (ベジータ, Bejīta), 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. He 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 along side them on Namek, and returns to Earth with them as well, where he remains for the rest of his life.
In Dragon Ball Z:Edit
Vegeta is introduced to Dragon Ball Z at 29 years of age as a mercenary for Frieza. Vegeta comes to Earth when he receives Raditz's dying report of seven magic objects known as the Dragon Balls which will grant wishes. After hearing this report, and of Raditz's death, Vegeta and his companion, Nappa, decide to come to Earth and use the Dragon Balls to wish for immortality (it is implied in later sagas that he desired immortality so he could defeat Frieza for his years of suffering). Goku and the Z Fighters are warned of their arrival, and begin to train themselves. While Vegeta and Nappa travel to Earth, they stop by Arlia in an anime filler. They were only there for a short time, and while they were there, they made short work of the planet's strongest warriors, before destroying Arlia altogether. When they landed on Earth, Nappa and Vegeta wreaked havoc with little to stop them. They then found Piccolo, Krillin, and Gohan waiting for them, with Tien Shinhan, Chiaotzu, and Yamcha appearing just after. After losing Yamcha (after one Saibaman self destructed), the rest of the Z Fighters powered up and defeated the remaining Saibamen.
