Gigantic Catastrophe is a technique used by Broly in his Legendary Super Saiyan form.
Broly fires a mouth energy wave, followed by a series of swirling energy bullets from his left hand. Finally, he charges up a massive energy wave and launches it at the opponent.
In Dragon Ball Super: Broly, Broly used the Gigantic Roar portion of this attack against Super Saiyan Blue Gogeta, but Gogeta dodges it and counters with a God Punisher and Stardust Breaker.
