"Struggle all you want, in the end you'll still die!"
Broly launches a lime green energy sphere that changes into an enormous energy bomb of devastating power, while saying "Struggle all you want, in the end you still die!" Not only can he control the size of this attack, but he can also power it up by launching ki blasts into it to push it forward, making it even more powerful and destructive enough to destroy the whole planet.
In the movie Dragon Ball Z: Broly - Second Coming, Broly first uses this attack in an attempt to kill Goku's sons, but Gohan and Goten counterattack with the Bros. Kamehameha. As Broly keeps powering up his attack, Trunks launches an energy blast at Broly's Omega Blaster to form a barrier, stopping Broly from powering up his attack and causing it to weaken and decrease in size. Goku, Gohan, and Goten then launch all of their power into the Family Kamehameha, which manages to break through the Omega Blaster and launches Broly into the Sun, which is believed to have killed him in the process.
Appearances in games
The technique is named Throwing Blaster (スローイングブラスター) in Dragon Ball Z: Super Butōden 2 and the first Dragon Ball Z: Budokai Tenkaichi, as Legendary Super Saiyan Broly's Ultimate Blast. It is called Gigantic Eraser as Legendary Super Saiyan Broly's Super Attack in Dragon Ball Z: Battle of Z, where he can also use a more powerful version as his Ultimate.
In the Budokai series and Dragon Ball Heroes, the technique is called Gigantic Meteor (ギガンティックミーティア). In the PS2 Budokai games, Broly uses the Eraser Blow and the Gigantic Hammer before charging the Omega Blaster energy sphere. If it is unsuccessful, he will throw the opponent instead of using the Omega Blaster.
The technique is named Omega Blaster in the Budokai Tenkaichi series, the Raging Blast games, and Dragon Ball Z: Ultimate Tenkaichi. In the Raging Blast games, in addition to being Broly's Ultimate Attack in his Legendary Super Saiyan form, this move is also a Super Attack for his Super Saiyan 3 form.
In Dragon Ball: Xenoverse, it appears under the name Gigantic Meteor and is Broly's Ultimate Skill. It can also be obtained by the Future Warrior as a reward in Parallel Quest 51: "Heated, Furious, Ultimate Battle". To perform the move, the attacker throws a medium-sized green energy sphere, disregarding the trajectory of it. To finish the move, the attacker throws a slightly larger energy sphere (the actual Omega Blaster), causing a gigantic explosion wherever the opponent is.
In Dragon Ball Z: Extreme Butōden, it appears under the name Rest in Peace and is Broly's Air Ultimate Combo.
