Vegeta is the Prince of the Sayians,and he appears after the death of Raditz. He comes with Nappa to Earth in an attempt to gain immortality by wishing it to Shen-long after he collects all the dragonballs. 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(Vejita seems to be about 10 years old in his 1 year space journey). Vegeta finally joins Gokuu and friends but never gets to be a real allie; he's only purpose in life is to defeat Goku and prove that he is stronger. Later in the series Vegeta is taken over by Majin Buu and becomes Majin Vegeta During the series he slightly settles down with Bulma having with her two kids: Trunks and Bra. Trunks is his first kid and Trunks grows up with Goten. Trunks wins the martial arts tournament and defeats Goten cheaply. Vegeta is very proud of this, because his son is stronger then Goku. Vegeta achives ssj4 after goku with the help of his technilogically advanced wife bulma. Bulma makes him a Brute Ray and he transforms SSJ4!!!!
