Super Saiyan God Goku (Battle of Gods)

God of the Saiyans based on the movie "Dragon Ball Z: Battle of Gods" when he transformed by the power of six pure-hearted Saiyans is needed for one of them to achieve this legendary form, even more powerful than the Super Saiyan 3.

Note that the SSG form resembles the similar forms used by Son Goku by his Super Kaio-Ken and the False Super Saiyan, though his hair was like his base, but red along with his eye color with the fire like aura.
