Broly grabs his opponent and vertically throws them down into the ground, inflicting a great deal of damage.
Broly uses this attack against Videl. Shortly after grappling her and throwing her a great distance away, Broly proceeds to grab Videl by the ankle and then throw her down into the depths of the lake.
Later, Broly uses this attack twice during his battle against Goten and Trunks. The first time occurs during his first encounter with the duo: after using the first part of the Revenge Demon rush as well as attempting to strangle Goten, Trunks hits Broly in the back with a Ki Blast to save Goten. However, Broly manages to use the Gigantic Throw portion to grab Goten and throw him into Trunks, launching both of them down into a nearby lake. The second time is while Trunks acts as the distraction while Goten tries to summon Shenron. After placing Trunks into a horrid backbreaker with his head (and subsequently getting urinated on due to Trunks being unable to hold his bladder anymore), angered at Trunks wetting himself, Broly uses the attack again to throw him down, eventually resorting to a Planet Geyser to finish him and Goten off.

The technique was named Gigantic Throw in Dragon Ball: Zenkai Battle: Broly launches his opponent like a missile, and they even explode upon impact. It is incorporated into Revenge Demon in the Raging Blast series.
