"A large Ki Blast that is followed up with a volley of smaller Ki Blasts if it hits."
He charges up a blast in a fashion similar to a Finish Buster, and fires it at the opponent to inflict a large amount of damage.
Vegeta uses a yellow attack similar to this technique against Final Form Frieza during their battle on Namek, but the tyrant simply jumps away from the blast. Later, Vegeta attacks Semi-Perfect Cell with the attack, causing an enormous explosion in the Tropical Islands.
Appearances in games
Saiyan Energy Attack was named in the Dragon Ball Z Collectible Card Game, where it is depicted as the version used against Semi-Perfect Cell.
Vegeta uses the final part of the in Dragon Ball Z: W Bakuretsu Impact. Super Saiyan 2 Vegeta uses it as his charged Ki Blast in Dragon Ball: Raging Blast 2, and as his Blast Spark in Dragon Ball Z: Battle of Z.
Super Saiyan Vegeta is shown charging up the Saiyan Energy Attack during the opening to Dragon Ball Xenoverse. In Dragon Ball Xenoverse 2 as part of the 1.05.00 Update, it appears under the name Focus Flash as a Super Skill which can be obtained by the Future Warrior (Xenoverse 2) as a reward in New Expert Mission 18: "The Ultimate Evil: Broly!". In Xenoverse 2, the user fires an Energy Sphere which the user follows up with an rapid fire energy barrage if the Energy Sphere hits. As a result, it functions like the version used by Vegeta against Frieza (Energy Sphere followed by an Energy Barrage), though has the coloration of the version Vegeta used against Semi-Perfect Cell.
Both Focus Flash and Wild Hunt appear as part of SSGSS Vegeta's Battle Suit skillset in Xenoverse 2 after the 1.07.00 Update, as they where not part of any of his skillsets previously.
