The Big Bang Attack (ビッグバンアタック, Biggu Ban Atakku) is an energy ball technique used by Vegeta in the Dragon Ball franchise. It makes its debut in "The Secret of Dr. Gero", the 130th episode of Dragon Ball Z, which premiered on March 11, 1992.
In order to perform it, Vegeta extends his arm and opens his palm and turns his hand up at a 90 degree angle (as if to signal "Stop") and starts to power up. He then fires a powerful sphere of ki, a large energy ball or comet-like energy projectile.
This attack is either yellow or white in color and creates an enormous explosion upon contact. This move is reminiscent of the supposed Japanese obsession with nuclear explosions as Big Bang Attack leaves a mushroom cloud like an atomic bomb in its wake.
Vegeta first used Big Bang Attack against Android 19 during the same battle that he first fought as a Super Saiyan. During a Kamehameha duel between SSJ2 Gohan and Super Perfect Cell, Vegeta also used an attack similar to Big Bang to distract Cell so that Gohan could launch all of his power to destroy the evil android, but it was yellow and differently shaped. The attack's name and state is also reminiscent of the Big Bang Theory of Existence.
Vegito also used it against Super Buu, but it is shaped into a beam, rather than a sphere of destruction, while retaining its vast attack power.
Baby, while possessing Vegeta, used an altered variation of the move, wherein the attack is reshaped into a beam, and launched with the Final Flash stance. The attack power remains the same, but now has the properties of a beam attack, rather than an explosive.
Appearance and power
Big Bang Attack has a few different colors. White is the standard and usual color. In some games, Big Bang Attack, even while in the Super Saiyan state is whiteish-blue. In Dragon Ball Z: Super Sonic Warriors 2, Vegeta can charge this attack to be moderately faster and more powerful, at which time it has a pink color.In Dragon Ball Z: Burst Limit, Vegeta can even use an enhanced version of Big Bang Attack called the Super Big Bang Attack.
