To preform the attack, Vegeta extends his arm, opens his hand, and charges ki in the palm of his hand, similar to the normal Big Bang Attack. However, Vegeta fires the attack as a beam instead of a sphere.
In Dragon Ball Super: Broly, Vegeta uses this technique as an attempt to finish off Broly, despite Goku yelling at him to not do it. The attack lands, hitting Broly and destroying the glacier he was on, landing into water below. The attack seemingly finishes Broly, but Broly powers up into his Wrath State unscathed.
