I haven't read this particular fanfic directly, but generally, in a 'bardock saves broly' fanfic, it might involve Bardock using his combat skills and intuition. Bardock, being a Saiyan, has a certain level of power and tenacity. He could potentially save Broly from some sort of danger, like a powerful enemy or a life - threatening situation on their home planet. It could also explore the relationship between the two Saiyans, perhaps Bardock seeing potential in Broly or having a sense of kinship towards him.
There's also 'Female Broly: A New Power'. In this fanfiction, it focuses on how she interacts with the other characters in a different way compared to the male Broly. It shows her as a complex character with her own motives and emotions, which makes it an interesting read.
Well, it gives a fresh perspective. Since Broly has always been male in the original, a female Broly in fanfiction allows for new storylines. For example, she could have different relationships with other characters. Maybe she has a more nurturing side compared to the male version.
A possible plot twist could be that Bardock actually saves Broly, but in doing so, he unknowingly sets in motion a chain of events that leads to an even greater threat. For example, by saving Broly, he might disrupt the balance of power among the Saiyans in a way that angers some powerful factions, who then form an alliance with an external enemy.
Honestly, there's no fixed date for the return of the DBS manga. It depends on various factors like the creator's schedule and production plans. But you can follow related fan communities or news sites for the latest updates.
The DBS manga is canon. It's recognized by the creators and fans alike. It follows the established rules and continuity of the Dragon Ball Super world, contributing to the rich narrative of the franchise.
