Well, he could change a lot of things. Maybe he'd prevent some bad events from happening in the past. For example, he could stop Frieza from destroying Planet Vegeta earlier. It would be really cool to see how his super saiyan power affects the past timeline.
Well, he might change some crucial events. For example, he could prevent some villains from ever rising to power. Maybe he'd stop Frieza from destroying Planet Vegeta earlier, which would change the whole Saiyan history and his own life. He could also teach his past self some new techniques, making the Saiyans even stronger in that timeline.
If Goku travels back in time as a Super Saiyan in fanfiction, his relationship with his past self would be complex. His past self might look up to him as a hero and a mentor, but at the same time, there could be some envy or confusion. With his Saiyan comrades, he could become a leader figure much earlier, changing the power dynamics among them. Also, his interactions with Earthlings would be different. They would be more fearful or more in need of his protection, depending on how he uses his power in the past.
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.
In this fanfiction scenario, Goku could meet Bulma when she was a child. He could befriend her in a different way compared to their first meeting in the original story. Also, he could run into King Kai at an earlier time and start training with him much sooner, which would significantly boost his power levels and change the course of his battles in the future.
Well, perhaps Goku travels back in time to meet his long - dead parents. He could have conversations with them, learn about his family's history in a more personal way, and gain new insights that help him in his present - day battles. Or he might go back to the time when the Saiyans were still on their home planet, and try to change the fate of the Saiyan race by warning them about their impending doom.
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.
