A fanfiction could focus on a parallel universe where Zamasu and Shin meet under different circumstances. In this universe, Zamasu is not as radical and Shin is more open - minded. They meet by chance and end up on a quest together. Along the way, they face various challenges that test their new - found friendship. Their relationship could be a slow - burn one, starting from mutual suspicion to a deep bond as they learn about each other's pasts and dreams.
The plot could revolve around a shared threat that forces Zamasu and Shin to team up. Maybe an even more powerful and malevolent force arrives in their universe. At first, they are hesitant to work together, but as the situation worsens, they have no choice. During their time together, they gradually develop a grudging respect for each other. Zamasu could be impressed by Shin's unwavering loyalty to his cause, and Shin could see some good in Zamasu's power, if it were redirected towards a positive end.
For Zamasu, give him moments of self - reflection. Let him question his own beliefs when faced with Shin's different perspective. For example, when Shin shows him acts of great kindness by mortals that Zamasu has overlooked. For Shin, put him in situations where he has to make tough choices that challenge his loyalty. This could cause him to reevaluate his own character. As the story unfolds, Zamasu could develop a newfound sense of empathy, and Shin could become more assertive in his beliefs and actions.
One possible plot could be that Lena and Shin meet in a post - apocalyptic world. They start off as strangers but are forced to team up to survive against various threats like mutant creatures and rival gangs. As they journey together, they gradually develop feelings for each other through shared hardships and moments of mutual protection.
One idea could be exploring their relationship in an alternate universe where they succeed in their plans. Another could be a story where Goku Black has a change of heart due to his connection with Zamasu and tries to stop their destructive ways. Maybe a plot where they face a new enemy that forces them to reevaluate their alliance.
One idea could be that they discover a new realm together and have to face an unknown threat there. Their combined power might be put to the test in ways they never expected.
Another option for the main antagonist could be Beerus. As a God of Destruction, he wouldn't be happy with Zamasu and Goku Black causing chaos. Beerus is extremely powerful and has the authority to deal with threats to the universe. He might see their actions as a direct challenge to his power and order. If he gets involved, he could completely change the dynamic of the story, as his power level is on a whole different scale compared to most characters in the Dragon Ball universe.
The Saiyans could also be antagonists. If they discover Black Goku's true nature and his alliance with Zamasu, they would likely oppose them to protect their race and the universe.
A good exploration of their personalities is key. Since they both have distinct traits, seeing how they interact based on who they are is important. For example, Zamasu's self - righteousness and Black's more primal power.
A common theme is power - seeking. They are often depicted as constantly striving for more power and ruling over the universe. Another theme is their unique bond, whether it's a friendship or a more sinister partnership.
Well, it could be about Sakura facing some sort of difficult situation while in Shin Uchiha's grip. Maybe she's being physically restrained and has to find a way to break free, perhaps using her medical ninjutsu skills or her inner strength.
One possible plot could be that Shin Natsume, with his unique abilities, somehow gets transported to the Naruto world. He meets Naruto and they initially have a misunderstanding as their worlds are so different. But then they realize they both have a strong sense of justice. Shin could use his powers to help Naruto in a battle against a powerful enemy, like a new Akatsuki member. They learn from each other's determination and courage.
