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 powered up state to defeat Golden Great Ape Baby Vegeta thanks to receiving Saiya Power from Pan and Super Saiyans Gohan, Goten and Trunks. 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.
