A recent film has shown us this possibility.
Despite the fact that at first it seemed that Freeza’s power had been questioned after the Cell and Buu arcs, the truth is that today the well-known villain is the strongest being in Universe 7 thanks to his transformation into Black Frieza, while Akira Toriyama and Toyotaro have wanted this to be the ultimate villain of the series to the point that it’s even banking-based in a much deeper way than we knew.
Given this, it must be said that in the current arc of Dragon Ball Super, which has Trunks and Goten as protagonists, it is known that Goku and Vegeta are training to be able to face Frieza, who, despite not wanting to kill them so far, was able to defeat them in a rather humiliating way at the end of the Granolah arc even when they were in their Ultra Instinct and Ultra Ego phases respectively.
Broly would be the chosen one to defeat Frieza
Now, thinking back, this training may be in vain, since in the past it was possible to see that Broly, of whom we have been able to learn a connection with Cell, would be the chosen to defeat Frieza permanentlybeing so that to understand this we must go to chapter 264 of Dragon Ball Z, in which the villain admits that a vision showed him that his death would be at the hands of the Legendary Super Saiyan.
It should be noted that at the time this was attributed to Goku, who transformed into a Super Saiyan in order to defeat Frieza in what was the longest five minutes in history. However, both this defeat and the subsequent ones have not been definitive, and so Frieza has come back from the dead again and again.thus giving rise to this vision making sense, since, if we stick to the current canon and lore, The Legendary Super Saiyan is Broly.
This is something that really shouldn’t be too important, since Toriyama most likely doesn’t even remember this vision, but if we take into account that Broly would also be training, it is possible that the Saiyan will have some role in the final fight. In fact, it could already be seen that in his movie he had no problem beating up Freeza.
