Usage and power
This state can be temporarily achieved by a Super Saiyan 4 by gathering enough Saiyan 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 Saiyan Power from Pan and Super Saiyans Gohan, Goten and Trunks. Goku again 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, and though his Dragon Hammer technique is able to obliterate Omega Shenron the dragon manages to regenerate.
