I'm talking about by powerlevels since then Goku's fight with Broly. By the way I seem to remember that DBZ movies were seperate from the canon storyline so it isn't canon to the storyline. Nonetheless, an entire group of stars blinking out in a few seconds seems to portray that Broly destroyed the majority of them. This is proof of galaxy busting, not entirely but most of it. Kid Buu is an evil creature that seems to enjoy killing and destroying things so it is proable he took his time destroying planets while Broly wiped out a galaxy because he was just crazy. Please stop the insults, there's no reason for that. But then again, how's reasoning going to work with you. Its failed so many times before...
