Well, if Goku was the legendary Super Saiyan in fanfiction, it could completely change the power dynamics in the Dragon Ball universe. There might be new enemies or allies formed based on this twist.
Definitely not. Fanfiction is a realm of creativity where the boundaries are pushed. There are fanfictions that might introduce new Saiyan characters who are the Legendary Super Saiyan. Also, different interpretations of the existing Saiyan lore can lead to scenarios where Goku isn't the sole Legendary Super Saiyan. For example, some fanfictions might play with the idea that the Legendary Super Saiyan is a title that can be passed on or shared among different Saiyans depending on certain conditions.
If Goku were the legendary Super Saiyan in fanfic, it could lead to new story arcs and challenges. Maybe he'd face even more powerful villains or have to deal with the weight of his immense power.
One more theme is friendship and family. Just like in the original Dragon Ball series, the female Goku in fanfiction also values her relationships. However, her Super Saiyan powers can sometimes put a strain on these relationships. For instance, her need to constantly train and get stronger might conflict with spending time with her family. But in the end, these relationships are usually strengthened through her growth as a Super Saiyan.
Sure does. Goku Black achieves the Super Saiyan form in the manga. This transformation adds a new layer of intensity to the storyline and showcases his growing power.
Another possible role for Goku in RWBY fanfiction is as a disruptor. His sudden appearance and his different set of powers and values could disrupt the existing order in Remnant. This could lead to positive changes as the characters adapt and learn from him, or it could cause some chaos as they struggle to understand and accept his presence.
The fanfiction should also do a great job of blending the two universes. Let's say it's a Goku and 'One Piece' crossover. The power - scaling, the different races, and the overall aesthetics of both universes need to be combined in a seamless way so that it feels like a natural and exciting story.
