Broly flies past the opponent with an Eraser Cannon in his hand that he brings near the opponent's stomach. He then throws his hand with the Eraser Cannon forward and, at point blank range, blasts the opponent away. The screen turns dark after the attack for dramatic effect.
Broly uses this attack during his battle against Gohan in the movie, Dragon Ball Z: Broly - Second Coming. After Broly effortlessly defeats Krillin (who comes to rescue Gohan from the lava), Gohan attempts to attack Broly, who retaliates with a barrage of small energy blasts. Though Gohan manages to dodge them, Broly soon attacks with the Eraser Blow, blasting Gohan away on to the ground.
Appearances in games
Eraser Blow was named in the Raging Blast games, where it is one of Broly's Super Attacks in his Legendary Super Saiyan form. Broly also uses the Eraser Blow in the Budokai series at the start of his Ultimate Attack; he charges at the opponent and attacks them with the Eraser Blow before brutally beating them down with the Gigantic Spike and finishing them off with the Omega Blaster. It is performed in Dragon Ball Z: Supersonic Warriors 2 when the R button is pressed during Broly's throw; instead of punching the opponent upwards, Broly throws them to the ground, which forces them to go up again, and then Broly grips them and performs the Eraser Blow.
In Dragon Ball: Xenoverse, it appears under the name Gigantic Omega and is one of Broly's Super Skills. It can also be obtained by the Future Warrior in Parallel Quest 51: "Heated, Furious, Ultimate Battle".
"Charges at the opponent and performs a melee attack followed by a Ki Blast. The Ki Blast is performed even if the charge misses."
