Vegeta would also be an important character. His rivalry with Goku would intensify even more. Seeing Goku achieve the Super Saiyan form early would fuel his jealousy and his desire to become stronger. He might even try to find new ways to train or gain power to catch up with Goku.
Perhaps in the fanfiction, Goku goes Super Saiyan early due to some special training or a unique emotional trigger. It could be that he witnesses the death of a different character, like Krillin, much earlier than in the original story. This extreme emotional distress causes him to break through his limits and transform. As a result, the Saiyan saga would take a different turn. Frieza might become aware of Goku's new power much sooner and plan different strategies to deal with him.
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.
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.
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.
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.
