Zamasu meets his end in the manga because he underestimates the strength and strategy of Goku and Vegeta. They exploit his weaknesses and deliver the final blow that finishes him off.
The idea of an alternate universe is also very common. Since Zamasu is from a different franchise, fanfictions like to create a new world where both Naruto and Zamasu co - exist. This allows for new character relationships to be formed, new storylines to be developed, and for the writers to be really creative with the setting and the overall plot.
One common theme is the clash of ideologies. Naruto has his values of friendship and protecting the village, while Zamasu has his own extreme views. So, this often leads to interesting conflicts in the fanfics.
Redemption could also be a theme. Although Zamasu in the original was quite villainous, a female Zamasu in fanfic might be on a journey of self - discovery and redemption. She could start as a bad character but gradually change due to certain events or interactions in the story.
She might be depicted as having a complex personality. On one hand, she could have a cold and calculating side due to her divine or self - proclaimed superior nature. On the other hand, there could be a hidden vulnerability that only the male reader gets to discover. This duality can make for an interesting exploration in the fanfic.
Well, in fanfics involving Female Zamasu and a male reader, it often explores a unique dynamic. The relationship could be based on the contrast between Zamasu's divine or complex nature and the more ordinary male reader. It might involve themes of power, redemption, or a journey of self - discovery for both characters.
In the manga, Goku managed to kill Zamasu by combining his strength with Vegeta and performing a joint attack. They also exploited Zamasu's weaknesses to gain the upper hand.
A common theme is power and corruption. Since both characters are power - hungry in different ways, many fanfictions explore how their thirst for power corrupts them further. For example, they might go on a rampage across different universes to gain more power.
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.
