The Dirty Fireworks (汚い 花火, Kitanai Hanabi) is an energy wave attack used by Vegeta.
Usage
First, Vegeta shouts, "Don't bother!" as he charges at his opponent and punches them in the stomach. Next, he uppercuts them up into the air and aims at them with his outstretched middle and index fingers held together. Then, Vegeta shouts, "I'll break you!" and creates a huge explosion on his opponent, inflicting a great deal of damage. Finally, after his opponent is destroyed, Vegeta says, "Hah, simple tricks."
History
Dragon Ball Z
Vegeta used this attack to kill a Saibaiman for not being able to defeat Tenshinhan.
On Planet Namek, Vegeta used this attack to kill Kewie as he fled from their battle.
Freeza used a similar attack to kill Kuririn after he nearly killed Piccolo with the Death Beam. This ended up being the tyrant's downfall, however, as this action pushed Son Goku over the edge and he transformed into a Super Saiyan for the first time.
Video games
It is named Final Impact in the Budokai video game series, Filthy Fireworks in the Budokai Tenkaichi video game series, and Flash Strike in Dragon Ball Z: Burst Limit. It is worth noting that in the Budokai Tenkaichi series, the name Final Impact is given to the Atomic Blast.
It later appeared in Dragon Ball: Raging Blast 2 and is one of Vegeta (Scouter)'s Super Attacks. It is no longer a rush attack as it is in the Budokai Tenkaichi video game series. Vegeta directly fires the attack at his opponent, similar to how Freeza fires his I Won't Let You Escape with Your Life! technique.
