Infinity Super Saiyan is the final form in the Super Saiyan process. Goku has only achieved this form and nearly killed himself doing it. This form can also be called the Ultimate Super Saiyan but it is usually called the Infinity Super Saiyan. Goku's counterpart has never achieved this form because he is too stubborn to concentrate. Goku can only go into this form when he is so angry that he can transform into Super Saiyan 1,000 so that requires a lot of rage. This form of a Super Saiyan is available in the two games Dragon Ball: Raging Blast 5 and Dragon Ball: Super Blast. In Dragon Ball: Super Blast, Goku has learned how to control this form and can transform anytime he wants to.
