First, focus on character development. For Gohan, show his growth from his past experiences. For the female androids, give them unique personalities. For example, one could be more curious and the other more reserved. Then, create a conflict. It could be an external threat like a new villain or an internal one like the androids struggling with their identity. Also, add some emotional depth. Let Gohan and the androids form a bond, like a friendship or mentorship, that the readers can root for.
One possible plot could be Gohan training the female androids. He might discover that they have hidden potential not just for combat but also for good. For example, they could start to show emotions and a sense of morality, and Gohan helps them explore these new aspects of themselves.
One common theme is redemption. Often, the female androids might have a past of causing harm, and through their relationship with Gohan, they seek redemption. For example, they might start to protect the innocent instead of causing destruction.
In such a fanfiction, perhaps future Gohan could warn present - day Gohan about upcoming threats that he has faced in his own timeline. He might share his experiences and knowledge, which could make present Gohan a stronger fighter and a wiser person.
One great 'Gohan x Fem Androids' fanfic could be 'Gohan's New Allies'. It shows an interesting dynamic between Gohan and the female androids as they team up against a new threat. The story delves into their relationships and how they learn to trust each other in the face of danger.
A possible plot twist could be that future Gohan is actually an impostor sent by an enemy to manipulate the real Gohan. Another twist might be that when they meet, their powers combine in an unexpected way that causes some sort of time rift or a change in the timeline.
In a fanfiction where Future Gohan meets Goku, it could be an emotional reunion. Gohan might be filled with a sense of relief and joy, seeing his father again. He could show Goku all the things he's been through in the future, and Goku would be both proud and sad about what his son has endured.
Future Gohan's character development would likely involve him becoming more resolute and determined. After all the hardships he's faced, he would grow stronger both physically and mentally. He might start as a somewhat broken hero, but as the story progresses, he'd regain his confidence and find new purpose in protecting what's left of his world.
I think Black Goku might have the upper hand. He has shown to be extremely powerful and has some unique abilities. His Saiyan body combined with Zamasu's knowledge makes him a formidable opponent.
