Broly's power is simply unbelievable, he is in my honest opinion the pinnacle of the DBZ villains canon or non-canon. His feats are still well...unmatched by other villains, and his capabilities are absolutely off the charts, what I find most interesting is that his power just simply continues to grow every time.
However, like ALL super off the wall villains, that is Brolly's weakness as an antagonist, he has the script that ultimately trumps him at the end. So regardless of how uber over the top he is, he would ultimately lose. Given obviously there are characters whom by now have potential to be much more powerful then Broly now (due to the fact that they have had time to continue to grow in power while Broly is already "dead"😉.
To me, the Broly movies which I watched back in 93 when it was first shown in Japan, where arguably some of the most boring DBZ movies ever in existence. Simply for the fact that in these match ups, Broly was simply so significantly more powerful then the Z Fighter Gang that it became ridiculously lopsided.
I mean...Broly just completely dominated Goku and bunch so convincingly that the battle was pathetic to watch. To me, Broly is undisputed, and stands heads and shoulders above everyone else, he is to me, the only antagonist, who "had" he'd of appeared in the actual canon like say after Buu, however had power to continue growing would be able to contend with the most powerful forms Goku, Vegeta, and Gohan would have to offer.
As for the speed of DBZ characters, and some people stating that they couldn't travel FTL speed. I mean, I read the DBZ Mangas way, way, way, way, way, way back in the days when they where only japanese, and within the original japanese mangas of the DBZ.
You had guys like Raditz which dodged Piccolo's Special Beam Canon which was clearly stated at the time to travel at the speed of light. So, it brings me to mind, if someone at this time period such as Raditz was already capable of such feats...how couldn't any of the other DBZ characters (Goku, Vegeta, Gohan, Trunks, Goten, Piccolo, etc, etc all come to mind) not achieve it in greater forms by the end of DBZ.
Reasons why in the anime of DBZ especially you have them flying 203948230942809 years is simply for plot reasons, this is not a form of showing that "well, since it took them so many episodes to get to spot, they couldn't fly FTL speed, or obtain".
That's just incorrect, remember, that at the time, the DBZ manga was very new, and the anime wanted to follow the manga, so they would prolong things and add fillers just to stall so the manga could catch up. Flying was one of those prolonged courses that was used within the anime.
Close to the beginning of the DBZ series, characters where moving so fast that even the human eye couldn't catch them. Not to mention, Goku's Instant Transmission puts speed to shame, as again, when reading the japanese manga DBZ of Cell when he first saw Goku utilizing it. Stating that it was Instant, which completely shocked and threw off Cell, so to me, the speed of the DBZ characters by the end is much greater then that of FTL.
I apologize if I kinda went off topic, however at times, it boggles my mind that some people would actually try to "downgrade" DBZ characters...seriously, these are some of the most ridiculous manga characters ever conceived...I mean seriously...Goku fighting ALL of the greatest martial artist from all the universes in the afterlife, and continuing to train to become more powerful...even killing them isn't enough.
Broly>All other Antagonist, not just in feats, but also the mere fact that he's a Saiyan gives him a stronger connection to the main protagonist characters of the series, instead of some alien/creature from outer space or created from some cells or magic or what not.
