There he watches the Z fighters fight and die against Nappa and the Saibamen and when Goku arrives, he was shocked as Goku's power level was over 9000. Vegeta first initially arrives as one of the antagonists in the series, as he was arriving to Earth with Nappa in search of the mystical Dragon Balls so he could gain immortality and defeat 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. 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.
