Broly shouts "Get out!" as he charges at the opponent and uppercuts them away up into the air. Then, he flies up into the air and lands on the ground, where he headbutts the falling opponent before roundhouse kicking them onto the ground. Finally, Broly runs at the reeling opponent and kicks them up into the air before blasting them away into the ground with an Gigantic Eraser, inflicting a massive amount of damage.
Broly uses this attack against Piccolo in Dragon Ball Z: Broly - The Legendary Super Saiyan. With the stone tower he is standing on being destroyed by Gohan and Future Trunks' Combined Masenko, Broly is sent falling to the ground feet-first with Piccolo in pursuit. However, Broly remarks Piccolo and attacks him with the Gigantic Buster rush (knocking out Gohan and Future Trunks in the process), battering the Namekian and blasting him meters away into a cliff.

Gigantic Buster was named in the Raging Blast series, where it is Broly's Ultimate Blast in his video game exclusive Legendary Super Saiyan 3 form. In Dragon Ball Z: Ultimate Tenkaichi, this attack is one of Broly's Super Attacks in his Legendary Super Saiyan form.
