From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
Super Gogeta attacks his opponent with a powerful and quick barrage of punches in their stomach. Next, he flies past his stunned opponent and turns around to knee them twice in the back of their head before backflip kicking them away. Then, he lands on the ground and raises his hand to charges a rainbow energy sphere. Finally, Super Gogeta turns around and throws the energy sphere, which has a delayed effect, but finally disintegrates his opponent from the inside, inflicting a huge amount of damage.
Super Gogeta used this attack to defeat Super Janemba in Dragon Ball Z: Fusion Reborn. While Pikkon was fighting against Super Janemba, only to be defeated by the monster, Son Goku and Vegeta successfully used the Fusion Dance to merge into Super Gogeta. As Super Janemba powered up and prepared to fight, Super Gogeta attacked and destroyed Super Janemba with the Stardust Breaker, removing all of Super Janemba's evil energy and restoring the young Ogre, Saike Demon, back to his former self.
Stardust Breaker is named in the Budokai Tenkaichi video game series and is Super Gogeta's Ultimate Blast. Originally, only the energy sphere at the end of the rush was featured in Dragon Ball Z: Budokai Tenkaichi and Dragon Ball Z: Budokai Tenkaichi 2. This was later fixed in Dragon Ball Z: Budokai Tenkaichi 3.
It is named Sōru Panisshā (ソウル パニッシャー, Sōru Panisshā) in Dragon Ball Heroes.
