Broly crushes all of them at the same time,Galaxy buster
Finished, Thanos will survive but would be knocked out
@supernova7005: Broly destroyed it in a instant, Not in years as nothing is proven he done it in years.
Also Nothing is indicating Dark seid can destroy or handle a galaxy level attack, Unless its Pre crisis Darkseid than maybe
If it is, Than it depends on how smart broly is and what he will do
@supernova7005: Being Attack also doesn't mean he done it over time, After the galaxy was destroyed he said attacked. And the way the galaxy is destroyed proves he one-shot it since its different to Kid Buu who done it in a few years. it started towards the middle and went towards the end at the same pace where kid Buu was parts getting destroyed
Also King Kai said broly can destroy his northern galaxy at the rate he is going, he wouldn't consider him a galaxy level threat if he was doing it in years to do so.
The Galaxy was a set up for Vegeta, So Yes he was attacking the galaxy to set it up for vegeta. To show the legend really exists
He either done a Very quick job or one-shot
Regardless he is a Small Galaxy level guy at minimum, Going LSSJ is going to make up for that,especially if he was a universal threat
