Super Saiyan 4 is the ultimate non-god form for saiyans.
Which is great, we can now say that Super Vegito and Super Gogeta in DBZ are both universal. This is a completed version of the Super Saiyan 4 bust, fixes gap/spacing from the base game bust, adds fur to the rist/end of arms, gives Super Saiyan 4 eyeline & eyes upon equipment (Eyes will match current eye color) Mainly created for users & modders to use for their own Super Saiyan 4 transformations. It then showed Frost's hidden weapon being removed in next episode preview.
The unlockable characters consist of the adult Super Saiyan form of Goku in his GT outfit, the Super Saiyan forms of GT kid Goku and Trunks, Z series Super Saiyan Goku, Super Saiyan Future Trunks, Vegeto and the Super Saiyan 4 form of Goku.
