Super Saiyan Blue, originally known as Super Saiyan God Super Saiyan, is a form that uses the power of Super Saiyan God with the first Super Saiyan form. This form can be accessed by absorbing the powers of god, activating them and then transforming into a Super Saiyan, or through vigorous ki control training with a deity with godly ki and then obtaining that Godly ki for oneself.

In Goku's words, this form is what happens when a "Saiyan with the power of a Super Saiyan God further transforms himself into a Super Saiyan". Simply, it is the first Super Saiyan form combined with the power and crimson ki of a Super Saiyan God turned cyan blue due to a mortal absorbing it. The form can be obtained by a Saiyan who has become a Super Saiyan God and then retained the power, if the Saiyan utilizes the might of Super Saiyan God, and then attempts to transform into a Super Saiyan, they will instead naturally evolve into a Super Saiyan God Super Saiyan (Super Saiyan Blue or Super Saiyan Rosé, depending on the individual's status). And reactivating their non-god enhanced Super Saiyan form. Alternatively, as shown in the anime and by Goku Black in the manga, the Saiyan can evolve their standard Super Saiyan form into a Super Saiyan God Super Saiyan form if they increase its strength until it surpasses Super Saiyan God. Super Saiyan Blue is the most powerful of all Super Saiyan transformations.
