This image has been floating around the net for a few weeks not but until today we didn’t know for sure if it was just a cool drawing on a studio door or the legendary Super Saiyan God.
Thanks to kanzenshuu.com who managed to get news from someone at the advanced screen we can confirm this is what Goku’s final form will look like.
The article which confirmed it also said that there are two parts to the transformation, one where he turns into the Super Saiyan God and one where he looks like normal Goku but can tap into the full power of a Super Saiyan God without the need to go through SSJ2 and SSJ3 forms.
Goku reaches this “Super Saiyan God” form — looking similar to the image seen on a Toei Animation office poster — surrounded by a red aura. Goku returns to his regular Super Saiyan form, but has now felt the form’s godlike power and is able to tap into it.
