As the prince of a demolished Planet Vegeta, Vegeta is initially introduced as an unrepentant villain. Judging from his evil intentions before joining the Z Fighters, Vegeta has been consistently characterized as extremely arrogant, vengeful, and at times, sadistic. Many of Vegeta's early heroic acts are because of self-interest or revenge, although he later settles down and mellows out, adjusting to Earth as his home, raising a family with Bulma.
