Vegeta is also one of the more interesting characters in the show. He starts off as a bad guy coming to take over the Earth and sell it to the highest bidder and ends up becoming a good buy and helps protect Earth in the end. Vegeta is always one of the strongest people in the universe and is the rival of Goku. Vegeta is always jealous of Goku's power because Vegeta was a Royal Sayain and Goku was a lower class Sayain scum. The first time Vegeta goes super sayain is when he gets mad at himself for not being able to go super sayain.
