One interesting plot could be Evil Goku's origin. Maybe he's a result of some dark magic or an alternate dimension's influence. Another plot might involve his battles against the regular Z - fighters. He could have new and more devious fighting techniques.
One interesting plot could be Dark Goku's origin story. Maybe he's not just an evil version of Goku but has a more complex backstory involving some dark magic or a different dimension's influence. Another plot might involve his battles against the Z - fighters. How he uses his unique powers against them and the strategies they come up with to counter him.
In a fanfic, it could be that Android 21 has a hidden power that only Goku can unlock. As Goku helps her discover this power, they form a deep bond. This power could be related to the Dragon Balls in some way, like having the ability to control the Dragon Balls' wishes or even create new Dragon Balls.
Well, in these fanfics, Bulma might be an important character. She could use her intelligence to create some sort of device or plan to stop Evil Goku. Also, Piccolo would be there. His strategic mind and powerful attacks would be crucial in the fight. And of course, there might be new characters created specifically for the fanfic, like a mysterious sage who knows the secrets to defeating Evil Goku.
One interesting plot could be a time - travel scenario where Goku and Bulma end up in an alternate timeline together. They might have to face new threats that are different from the ones in the main story. Another could be a story where they go on an adventure to a new planet and discover a powerful energy source.
In some fanfictions, a plot could be Goku trying to teach Ultra Instinct to his friends. Vegeta, in particular, might be a reluctant student at first but then realizes the power's potential. This could lead to a whole new dynamic among the Z - fighters, with them all striving to master this god - like ability.
A third possible plot could be a story where Goku and Bulma are separated from the rest of the Dragon Ball gang. They have to rely solely on each other to survive and find their way back. During this time, they discover new powers within themselves and also learn more about each other's pasts, which brings them closer together.
One interesting plot could be Goku and Bulma navigating the challenges of combining their very different lifestyles. Goku, being a Saiyan warrior, is used to constant training and battles, while Bulma is more into technology and inventing. In the fanfiction, they might struggle to find common ground in raising their family. For example, Goku might want to train their children in martial arts from a very young age, but Bulma could be more concerned about their academic education and safety. Another plot could be them facing threats from enemies who target their relationship. Maybe an old foe of Goku sees his marriage to Bulma as a weakness and tries to use it against him.
One interesting plot could be Goku's daughter having to train in a new dimension. She discovers unique powers there and has to use them to save the Earth from a new threat. This would be a great way to explore new aspects of the Dragon Ball Z universe while also focusing on a new character, Goku's daughter.
One interesting plot could be Goku traveling back in time to train with his younger self. He could teach his younger version some new techniques, like the Instant Transmission at an earlier stage. This would change the power dynamics in the earlier story arcs and lead to different battles against foes like Vegeta. Maybe the Z - Fighters would be stronger and better prepared for future threats.
Goku in the Dragon Ball manga is not evil at all. He's the one who constantly overcomes challenges through his determination and positive attitude, always striving to do the right thing for the greater good.
