Super God Class-Up (超ゴッドクラスアップ,Sūpā Goddo Kurasu Appu) is a special skill exclusive to the Hero Avatars characters in Super Dragon Ball Heroes. Using this ability, players can promote their Hero Avatar(s) from the God Class.
The skill increases the abilities and attributes of the Hero Avatar and changes their appearance. When used by a Saiyan avatar for example, the Saiyan avatars gain the ability to become Super Saiyan Blue, the other avatars gain their own transformation and an increase in power. In addition, they also gain new clothes or some differences in their outfits are provided for all the avatars.
Unlike the usual physical changes of a traditional Super Saiyan Blue transformation, all Saiyan avatars retain their base form hair while using it.
