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 great Super Saiyan Blue Goku crossover fanfiction is 'Goku in the DC Universe'. It's really exciting to see Goku interact with Superman and other DC heroes. He has to adjust to the different power levels and rules in that universe.
