Prince of the Saiya-jin, appears after the death of Raditz. He comes with Nappa to Earth in an attempt to gain immortality by wishing it to Shen-long. He appears first with brown hair (in the anime) and slightly different looks, but after a year, when he comes to earth, his looks are already the same as those that we see for the rest of the series(Vejiita seems to be about 10 years old in his 1 year space journey). Vejiita finally joins Gokuu and friends but never gets to be a real allie; he's only purpose in life is to defeat Gokuu and prove that he is stronger. During the series he slightly settles down with Bulma having with her two kids: Trunks and Bura
Vegita is the "bad guy among the good guys." He first made his appearance back when Gohan was 4. Although he fights alongside the other Z fighters, he is still decidedly evil. As the prince of the Saiyans, he is very proud, has a huge ego, and is constantly trying to prove that he is the best fighter in the universe. Vegita has a continual rivalry with Goku, or "Kakarott," (Goku's Saiyan name) and is obsessed with beating him in combat just to show that he is the stronger. This obsession with trying to be stronger than Goku proves to be a fairly large weakness as well. Despite his efforts to show otherwise, Vegita has changed and has developed a conscience, and deep down cares about his friends. Furthermore, he is also somewhat emotional at heart. He demonstrates this when dealing with his son Trunks, most notably just before he died trying to kill Majin-Buu. Although he pretends to hate Goku with a passion in reality he respects his power and maybe even likes him a bit.
