"Unleash a super-powered Ki Wave that fuses two techniques together! It's powerful, but also uses up a lot of Ki!"
Final Kamehameha (ファイナルかめはめ波, Fainaru Kamehameha) is a combination of Goku's Kamehameha and Vegeta's Final Flash used by Vegito. This is the first and so far the only move to be introduced in video games that later appeared in the main series.
First, Vegito puts both of his hands forward and then towards his side, combining the massive power of the Final Flash and the Super Kamehameha into one attack. Then, Vegito fires the attack, as it appears as a giant, blue energy wave (resembling the Super Kamehameha) with swirls of yellow ki (resembling the Final Flash), inflicting an enormous amount of damage.
Super Saiyan Blue Vegito uses this attack during his battle against Fused Zamasu in Dragon Ball Super. As Fused Zamasu grows more and more powerful due to his intense emotions, Vegito knocks Fused Zamasu away and proceeds to finish him off with the Final Kamehameha. Fused Zamasu emerges the attack unharmed and Vegito attacks him further, however he immediately defuses and Goku and Vegeta are then defeated. Having used the Final Kamehameha as Vegito left Goku and Vegeta too weak to transform into a Super Saiyan again. In the manga, however, Vegito was unable to complete the attack before defusing.
Final Kamehameha makes its debut appearance in Dragon Ball GT: Final Bout and since then, it appears as one of Vegito's techniques in Dragon Ball Z: Shin Budokai, Dragon Ball Z: Infinite World, Dragon Ball Z: Budokai Tenkaichi 3, Dragon Ball Z: Tenkaichi Tag Team, the Raging Blast series, Dragon Ball Z: Ultimate Tenkaichi, Dragon Ball Z For Kinect, Dragon Ball Xenoverse 2 and Super Dragon Ball Heroes. In Dragon Ball Z: Dokkan Battle it is one of Vegito's Super Attacks. In the games, he holds it out like a Final Flash and moves it back like a Kamehameha, and then releases it in a golden-yellow colored beam (it is a blue and white color in the Raging Blast games and Dragon Ball Z: Ultimate Tenkaichi).
In Dragon Ball Xenoverse 2, the Final Kamehameha appears as one of Vegito's Ultimate Skills which the Future Warrior can obtain by purchasing it from the TP Medal Shop (which is open from Friday to Sunday). Though it is powerful, it uses up 5 Ki Bars to fire (in contrast both the Final Flash and Super Kamehameha only require 3 Ki Bars).
In Dragon Ball Fusions, it can be learned as a special move by Vegito after reaching Lv 52.
- When performing the attack in Dragon Ball GT: Final Bout, Vegito yells "お次はこいつだ！ファイナルかめはめ波 O tsugi wa koitsu da! FAINARU KAMEHAMEHA!" (Next one is this! Final Kamehameha!).
