Final Flash (ファイナルフラッシュ) is one of Vegeta's signature attacks (along with Galick Gun and Big Bang Attack), and supposedly the second most powerful of all of Vegeta's attacks (after the Final Shine Attack). In order to perform this technique, Vegeta draws his hands back and gathers up all of his energy. Then, he thrusts his palms forward and discharges a massive golden-yellow beam of energy towards his opponent.
The Final Flash is first used by Vegeta during his battle against Perfect Cell. Though Cell is significantly more powerful, the incredible amount of energy that Vegeta puts into the attack, reflected by significant charge time, obliterates the top half of the overconfident bio-android. Cell taunts Vegeta by standing still, impying that he will take the blast's full force. Sensing the danger only at the last second, Cell attempts to dodge the beam as the destructive energy disintegrates the ground on which he stands and continues off into deep space. When the dust clears, Cell has lost half of his upper torso. Despite this and to Vegeta's surprise, Cell is able to regenerate himself, shocked that the attack was actually able to damage him, and continues the fight.
Vegeta uses the Final Flash to kill Dr. Raichi in the OVA Dragon Ball Z Gaiden: Plan to Eradicate the Saiyans. Later, when Vegeta uses the Final Flash against Hatchiyack, he is shown charging it normally but when he fires it, he is seen doing it with one hand (in a similar manner to the Maximum Flasher).
Only in the anime, Vegeta uses the Final Flash against the Cell Jr. he is fighting against, but the attack is easily dispatched. In this instance, Vegeta spends only a few seconds charging up the attack rather than the several minutes used against Perfect Cell (presumably due to the desperate situation at hand), which could explain why the Cell Jr. managed to effortlessly deflect an attack that Perfect Cell himself was previously vulnerable to defend from.
Vegeta later uses it against Super Saiyan 2 Goku as Majin Vegeta (the attack name is heard, but not seen, as he placed the fingers of his hands upward instead of the heels of his hands to each other, much more like the Final Burst Cannon).
Vegeta later uses the Final Flash against a swarm of Kid Buus while buying time for Goku to charge his Spirit Bomb. Goku also uses a very similar move against Kid Buu while fighting in his Super Saiyan 2 form in an anime filler sequence.
Baby uses it against Goku on Earth, but Goku avoids it, and he uses the Final Flash twice during his battle against Uub. When Baby Vegeta uses this attack, he shouts "Big Bang Attack!" and the energy wave is purple in color.
Vegeta, while in his Super Saiyan 4 state, uses a blue/green Final Flash against Omega Shenron, along with Goku's 10x Kamehameha hitting the Shadow Dragon at the same time, but to no avail. This blue/green Final Flash is named Final Shine Attack in the Budokai series.
Appearances in Video Games
The Final Flash appears in several video games, including the Gokuden series, the Butōden series, Dragon Ball Z Arcade, Dragon Ball Z 2: Super Battle, Dragon Ball Z: The Legend, the Budokai series, the Budokai Tenkaichi series, Super Dragon Ball Z, the Raging Blast series, Dragon Ball Heroes, and Dragon Ball: Zenkai Battle Royale.
In Dragon Ball: Raging Blast 2, when Super Vegeta performs the Final Flash, it has the original yellow color, yet when Super Saiyan 2 or Super Saiyan 3, it is charged and fired in a blueish color. When Gogeta uses it in Dragon Ball Z: Ultimate Tenkaichi, it is blue/green.
Super Buu can use the Final Flash in Dragon Ball Z: Budokai 2, but only after absorbing Vegeta.
- Prior to his battle with Cell, Vegeta used a similar attack against Recoome during their battle on Namek, the Final Crash. The posing for the attack is nearly identical to Vegeta's Final Flash, with the only difference being that Vegeta's fingers are splayed straight out when he thrusts his hands forward instead of being bent forward. Also, the Final Crash energy wave has a blue color.
- It is stated by Piccolo if Cell had took the full force of the Final Flash, he would have been destroyed. Vegeta had no choice but to maneuver the beam upward to avoid destroying the Earth, which allowed Cell to survive the attack.
