Double Galick Cannon
From Dragon Ball Encyclopedia, the ''Dragon Ball'' wiki
First, Vegeta charges at his opponent, but stops right in front of them and places both of his hands on his opponent's chest. Next, he grins up at his opponent and charges yellow energy in his hands. Finally, Vegeta fires the yellow energy in the form of a massive wave of energy against his opponent, inflicting a huge amount of damage.
Vegeta used this attack in his fight against Puipui. Wanting to give Puipui the advantage, Babidi teleported the fighters to Puipui's homeworld, Planet Zoon, which had 10 times the gravity of Planet Earth. Puipui tried to attack Vegeta only to be pummeled once again by the Saiyan prince due to his earlier training under 450 times Planet Earth's normal gravity. As Puipui stood back up and attempted to attack again, Vegeta appeared in front of him and blasted him with the Double Galick Cannon, destroying Puipui and winning the fight.
It is named Dash Bomb in Dragon Ball Z: Hyper Dimension.
It also appeared in Dragon Ball Z: Ultimate Battle 22 and is Vegeta's throw move.
