Later, during their sparring match under Whis's supervision, Vegeta transformed into Super Saiyan God Super Saiyan in frustration due to Goku teleporting. Moments later, Goku transformed, but shortly after bit his tongue due to saying the name of the form multiple times. Because of Goku's request to change the long name, Whis suggested Super Saiyan Blue. Because of a competition with the 6th Universe formed, Goku and Vegeta trained in the Room of Spirit and Time for three days and used Super Saiyan Blue to test their full power. During the competition after their training, Vegeta transformed into Super Saiyan Blue against a Saiyan from the 6th Universe, Cabbe, and told him to train to achieve that power.
Vegeta then used Blue in his match against Hit, but because of his use of the form during his match with Cabbe, Vegeta was unable to defeat him. In the next match, Goku used Blue in his match against Hit after learning his Time-Skip, but the Saiyan later dropped out of the match because Hit was uable to use his full power.
