In 'Dragonball GT' this is the fourth level of a
Super Saiya-jin. It is characterised by
reddish fur growing over the body, and the person's hair becoming longer and shinier, also an incredible source of power that allows the person to perform the
Juubei Kamehameha.
Gokou and Vegeta both attained the Super
Saiya-jin 4 (
SSJ4) form. When they fused they created SSJ4
Gogeta.
