Definitely a fighter, Vegeta works best as a warrior, especially with rifle to yell out "Galick Gun!" when using the burst skill. While Black for the hair color can work to make non-SSJ Vegeta, the excessive sideburns stand out and take away from the look.
Make sure to wear a Catcher of some kind as a back item, as the Brawn of Koda chestpiece looks funky from the back.
