The Galaxy Breaker (ギャラクシー ブレイカー, Gyarakushii Bureikā) is an energy wave used by Vegeta. Vegeta generates electricity around his chest and converts into a bluish-white aura around his body. He then thrusts his chest forward and fires a huge energy wave at the opponent, inflicting a high amount of damage.
Vegeta used this attack to kill his former comrade, Nappa. After watching Nappa's defeat by Son Goku and marveling at the latter's abilites, Vegeta was disappointed that Nappa lost to Goku, a low-class warrior. Deceiving Nappa into thinking that Vegeta was going to help him, the Saiyan prince threw him high into the air and destroyed him with the Galaxy Breaker much to the shock of Goku, Son Gohan, and Krillin.
Freeza also used a similar move named the Death Comet out of frustration when Vegeta stole his Dragon Balls on Planet Namek.
Galaxy Breaker is named in Dragon Ball Z: The Legend and is one of Vegeta's attacks.
