One possible fanfiction could be Gt Goku traveling back in time to prevent the destruction of Earth in an earlier timeline. He could use his knowledge from the GT era to stop a powerful enemy that was previously victorious.
In a Gt Goku time travel fanfiction, he might go back to the Saiyan - Saiyan war era. There, he could introduce new techniques to the Saiyans, changing their future. For example, he could teach them about the Spirit Bomb, which could potentially make them more powerful and change the course of their history. This would also have a huge impact on the future, as the Saiyans are an important part of the Dragon Ball universe.
In a Gt Goku time travel fanfiction, Gt Goku might travel to a time when the Namekians were first attacked. He could help them defend their planet more effectively. This would not only save the Namekians but also have a big impact on the Dragon Ball story. Because the Namekian Dragon Balls are crucial. If they were never stolen in the first place, many events in the story would be different. And Gt Goku's actions could also lead to a different relationship between the Namekians and the Earthlings.
Baby Goku in GT fanfiction is significant because he allows writers to explore uncharted territories of the GT universe. His character can be used to create new plot twists and turns.
Baby Goku in GT fanfiction can be a really interesting concept. A lot of times, authors will play with his Saiyan nature more. They might show him struggling with the dark side of his Saiyan instincts, which was somewhat present in the GT series but can be expanded upon in fanfiction. This could lead to some really cool character development and new story directions.
Well, he could change a lot of things. Maybe he'd prevent some of the big battles or save some characters who died. For example, he might stop Frieza from destroying Planet Vegeta earlier. It would be a whole new timeline with different outcomes.
Goku's godlike power might make his time travel more precise. Normal time travel in the Dragon Ball universe can be a bit haphazard, but with his godly energy, he could target specific moments more accurately. For instance, he could arrive at the exact second he wants to in the past or future.
If Goku travels back in time, his relationship with Bulma could be very different. In the past, she was more of a guide to him. But if he goes back with his current knowledge and power, he could become more of a protector for her. He might also be able to prevent some of the dangerous situations she got into in the original story.
One possible scenario in this fanfiction could be that Android 18 and Goku are forced to time travel due to a new threat that endangers the entire universe. They might travel to a time when the Saiyans first arrived on Earth. Goku, with his knowledge of the future, could try to change some events to prevent future disasters. Android 18, with her strength and unique abilities, would be a great ally in this adventure. They might face challenges like dealing with the primitive technology of that time and also having to hide their true identities to avoid disrupting the timeline too much.
Well, his relationship with Vegeta would be interesting. If Goku went back in time and showed Vegeta the SSJ God form too early, Vegeta might become more competitive or even jealous earlier. He might push himself even harder to catch up, which could lead to more intense rivalries and also more joint training sessions between them.
Another option is a crossover with a different anime world, like Naruto. GT Goku could end up in the Hidden Leaf Village. The shinobi would be amazed by his power. Goku, being Goku, would be interested in learning their ninja techniques. They could team up against a common enemy that somehow has the ability to use both chakra and ki, creating a unique and exciting battle scenario.
When GT Goku goes back in time in fanfiction, his character may change in many ways. He could be more of a planner, thinking ahead about how to avoid the mistakes of his original timeline. He might also be more protective of his friends and family, knowing what they had to endure in the future. His sense of responsibility would likely grow, as he now has the power to shape the past and create a better future. This could lead to him being more involved in the political and social aspects of the Saiyan and Earth communities, rather than just focusing on his own training and battles.
