Usage and power
This state can be temporarily achieved by a Super Saiyan 4 by gathering enough Saiya Power from other Saiyans. It possesses much greater power than the ordinary Super Saiyan 4 form.
Goku first used this form in battle against Syn Shenron, taking energy from theSuper Saiyans, Gohan, Goten and Trunks to restore his power but then continues to take even more power from them to push his body past his limits at the risk of it killing him. With the power of this form he is able to overwhelm Syn Shenron, the latter being no match for him in power. However, he in turn is overwhelmed by Omega Shenron, and though his Dragon Hammer technique is able to obliterate Omega Shenron the dragon manages to regenerate.
- Though it does not appear in Xenoverse 2 this powered up state is referenced by Super Saiyan 4 Goku's Super Soul, Full-Powered Super Saiyan 4! which largely boosts normal attack power when the user is revived.
