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 the anime, Vegeta is shown using this transformation again against Future Trunks, as he laughed when Trunks asked Vegeta if he would transform into a Super Saiyan 3. Trunks remarked that Vegeta and Goku should easily be able to beat Goku Black. As their battle continued, Vegeta was able to easily defeat Trunks. However, the aforementioned fight against Black turned out more difficult than expected. Vegeta and in the anime only Goku use this form while battling Goku Black, before and after he transforms into Super Saiyan Rosé. Despite their efforts, in the anime Black's improved base form (which previously fought on par with Goku's Super Saiyan 2) was easily able to withstand most of the attacks Super Saiyan Blue Vegeta dealt, and in the manga Super Saiyan Goku Black manages to match Super Saiyan Blue Vegeta thanks to being healed by Future Zamasu and receiving a power up, and Black's transformation into Super Saiyan Rosé only made the situation more critical. In the anime, after training in the Hyperbolic Time Chamber and going back to the Future, Vegeta was shown to have increased his power through anger enough that in his Super Saiyan Blue form he managed to overpower and pummel Goku Black, who was in the Super Saiyan Rosé state at the time even blocking Black's Fierce God Slicer with his bare fist.

In the Super manga, by the final fight against Goku Black and Future Zamasu, Vegeta revealed the ability to utilize Super Saiyan Blue's immense power boost in short, instant bursts as he attacks. It is noted by Goku that in order to counteract the form's stamina drawback, Vegeta learned to transform into Blue for brief moments multiple times without his stamina dropping at all, something that allowed him to overwhelm Black.
