Usage and power
This state can be temporarily achieved by a Super Saiyan 4 by gathering enough energy. It possesses much greater power than the ordinary Super Saiyan 4 form.
Goku used this form in battle against Syn Shenron, using energy from Super Saiyans Gohan, Goten and Trunks. 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, though his Dragon Hammer technique is able to obliterate Omega Shenron he manages to regenerate.
