Yes, there might be such fanfics out there. In the Naruto fandom, with a large number of fans creating various types of stories, it's possible that some would write a story where Naruto destroys Sasuke in a way that could be seen as Sasuke - bashing. However, these kinds of fanfics may not be in line with the overall spirit of the original work which focuses on their complex relationship and growth.
There could be Naruto. Since he and Sasuke have a strong connection in the original series, he might also be involved in the gamer fanfiction, maybe as a rival or teammate in the gaming world.
In this kind of fanfiction, Sasuke could die from a sneak attack. He might be so focused on his main target during the Wave mission that he doesn't notice another hidden threat. And this hidden enemy could strike him when he least expects it, leading to his death. For example, an assassin could be hired to specifically target Sasuke and use some sort of poison or a deadly jutsu that he can't defend against in time.
There could potentially be some really creative and out - of - the - box fanfictions with this concept. But finding one might be a challenge. You could try searching on specialized fanfiction websites and use specific search terms like 'Kakashi Sasuke non - traditional relationship fanfiction' and then look through the results to see if there are any that involve the idea of Sasuke being pregnant. But remember, this is a very unusual concept even for fanfiction.
Sasuke would probably be very guarded at first. He's not used to dealing with something so innocent and vulnerable. He might be suspicious of the baby's presence and think it's some sort of trap.
He might meet the future versions of Naruto and Sakura. Their relationship with him could be very different in the future, perhaps they are now leaders of the village and Sasuke has to adjust to their new status.
Sasuke would be furious. He's always been protective of Naruto in his own way. He would immediately start looking for her, using all his skills and resources. He might even go on a rampage if he thought Naruto was in serious danger.
Naruto is often paired with Sasuke. Their bond is so strong that in post - war fanfictions, they are usually shown working together to rebuild the shinobi world. Sakura is also a common character paired with Sasuke. Since she has feelings for him, in these fanfictions, she might be trying to get closer to him and help him heal from his past traumas.
One possible theme could be revenge. If the writer is bashing Sasuke, they might have Naruto seek revenge on Sasuke for his actions in the original story, like when Sasuke left the village. Another theme could be power display, showing Naruto's overwhelming power as he destroys Sasuke.
Well, I'm not sure if there are a lot of 'Naruto Sasuke demands Sasuke bashing fanfic' specifically. Fanfic content can vary widely. Some people might write such things out of a desire to explore alternative scenarios or because they have a negative view of Sasuke. But I would encourage you to look for fanfics that are more positive and in - depth about the characters instead.
