Final Explosion was used against Majin Buu as a last resort by Vegeta. After bidding farewell to his family, as well as Goku, Vegeta released his entire energy and life force in a deafening scream, which causes a enormous, devastating golden-yellow explosion wave. In addition to turning his body into stone, this attack was able to destroy most of Buu's body, leaving only confetti bits behind. However, due to Majin Buu's regeneration ability, it was able to reform it's body, making Vegeta's explosion and sacrifice pointless.

There is also a belief that Vegeta may have been unable to complete the attack due to his stone form at the end of it. Buu had eaten Dabura, who had the ability to turn flesh to stone with his saliva, and because Evil Buu absorbed Fat Buu through consumption, it's possible he gained Dabura's spitting ability in the same manner. This "alternate" outcome is merely speculation although seems to explain the stone body left behind rather than nothing, especially since Vegeta's face looked surprised in his stone form. This is unlikely though because Majin Buu was seen screaming while being blown away by the attack. In Final Bout, he doesn't lose his health; instead it uses his whole energy bar. It is one of his strongest moves in both the anime and video games, but its usage costs him his life, with the exceptions in Dragon Ball Z: Super Sonic Warriors 2, Dragon Ball GT: Final Bout, and Dragonball Z: Infinite World .

Vegeta using a similar attack to Final Explosion, most likely a Super Explosive Wave, in the Vegeta Saga
Vegeta also used a scaled down version of the attack in the Vegeta Saga against Goku when he used the Kaio-ken attack. In this adaptation, Vegeta did not lose his life. In the Budokai Tenkaichi series this version of the attack is called Super Explosive Wave and is used by many characters.
