No, he used a simple energy ball albeit one enough to destroy an entire planet without charging the energy ball. Brolythelegend 19:15, June 28, 2010 (UTC)
Didn't Broly charge an Eraser Cannon first, then an Omega Blaster? Also, should this technique be it's own page, his ultimate technique from Infinite World? http://www.youtube.com/watch?v=NvXVNOL_eUY 045:~1:15?
Omega Blaster shrunk because it was overwhelmed
I've been rewatching that scene over and over and here's what i observed:
1. Broly v.s. Gohan, the Omega Blaster did not receive any additional Ki, it didn't shrink, and overwhelmed Gohan's Kamehameha.
2. Broly v.s. Gohan + Goten, the Omega Blaster did not receive any additional Ki, it didn't shrink, and overwhelmed both Kamehamehas.
3. Broly v.s. Goku + Gohan + Goten, at first Broly didn't feed the Omega Blaster additional Ki blasts. He only started feeding it after Goku's Kamehameha finally started to push the Omega Blaster back. This shows that the Omega Blaster is NOT reliant on a steady supply of Ki.
4. When Broly's additional Ki blasts were obstructed by Trunks, the Omega Blaster was first pushed back and then it shrunk, signifying that the size decrease happened because it was getting overwhelmed by the kamehamehas, not because it didn't have a supply of Ki blasts. If it was because of the lack of additional Ki Blasts, it would've shrunk before being pushed back, not the other way around.
So considering the fact that Broly only added Ki blasts after Goku's Kamehameha started pushing the OB back and not during the whole thing, I think it is incorrect to say the attack has a "weakness" and "Without a steady supply of ki blasts, the Omega Blaster will shrink and weaken in power." The Omega Blaster shrank because it was being overwhlemed by the Kamehamehas. If Goku didn't join in Gohan and Goten would've died to an unboosted Omega Blaster that never received Ki blasts.

I agree, it was the whole reason he kept adding more energy to it, to make it stronger and not to sustain it. So the part about it being a weakness is wrong. Trunks just prevented Broly from giving it more power. FlatZone (talk) 08:38, February 10, 2020 (UTC)
