The problem with Broly is that no one really knows how powerful he really is, however, I have a theory, although it’s all conjecture on my part…
In the first film, Broly beat the crap out of Goku, Gohan, Trunks, Vegeta and Piccolo. And he only lost due to PIS. Now the issue with this movie (and every other DBZ film) is placing it in the timeline. Gohan was able to turn into a super-saiyan, so does that mean it took place during the seven day wait for the Cell games? Two problems, Trunks was wearing the wrong clothes for that, and Goku and Gohan should have already been super-saiyans from the start. So, the first film can be overlooked as a measure of Broly’s power due to these inconsistencies.
The second film however, is a completely different story…
This film, unlike the first one, can be placed in the timeline with ease, taking place just before the Buu saga, Broly locks horns with Gohan, Trunks, Goten and Videl. In the first half of the film, Broly easily dominates Trunks and Goten. When Gohan shows up, they have a little scuffle, then they both go to full power, Broly goes LSSJ and Gohan goes SSj2, the animators said Gohan WAS SSJ2, they just forgot to add the “lightning.” Even as an SSJ2, Gohan was still outclassed by Broly. But, as Vegeta would state during the world tournament, Gohan “was a lot stronger” when he had fought Cell, meaning that he had become weaker. However, the real measure of Broly’s power is at the end of the movie, when Goten inadvertently wished that “dad was here” and Goku shows up to help his sons. Broly then gets into a beam war with SSJ2 Goku, SSJ2 Gohan and SSJ1 Goten (though he can be ignored) Now, when Goku fights Majin Vegeta not too long after, Vegeta says “at least you’re stronger than your son was when he fought Cell”
That implies that Goku is at this point is STRONGER than super perfect Cell and teen Gohan ever were (as I believe them to be equal in power) now, back to the beam war. Broly was shown as easily overpowering ALL THREE of them, so that means he has more combined power than a full powered SSJ2 and a weakened SSJ2. Which, needless to say, is pretty damn strong.
Now as for the gauntlet, considering Broly had enough power to easily overpower a fully powered SSJ2 Goku, I think he has a chance of beating SSJ3 Gotenks, but that’s as far as he’ll go, IF he gets past Gotenks, Mystic Gohan is going to wipe the floor with him. "
i do agree with you on a lot of this but dont forget goku and broly never did fight it was just a beam struggle and even though somebody is weaker they can still beat someone with a huge ki blast like with goku using the spirit bomb on alot of occasions to win also gohan with his power cut in half still able to beat cell so there is alot of cases where when the person is weaker they can pull of a huge ki blast that might be able to beat the enemy also broly has a lot of power built up and can rip off a huge ki blast that can seem unbeatable
i think him, teen gohan and goku are the people that can pull of a victory even though they may be weaker broly is one of the most powerful in dbz in making a huge ki blast thats why i think he would beat SPC in a goood fight even though i think SPC maybe stronger then him but he will lose to gohan because he can pull of a huge ki blast just as well and as for the timeline i dont think nobody went in the time chamber and for the movie like i said broly looked like he was done playing and was about to destroy the planet so he put up a huge ki blast and it was hard for goku to overcome it even with his sons help
