Who could be the main antagonist in a 'Naruto descendant of Moka' fanfiction?

It could be a rogue ninja who wants to steal the power of the descendant. This ninja might believe that by obtaining the Hamura - related powers, they can rule the ninja world.

Another possibility is a group of ninja from a rival village. They fear the power that Naruto might gain from his Raizen heritage and decide to take preemptive action. They could be led by a power - hungry shinobi who believes that by eliminating Naruto, they can prevent the Hidden Leaf Village from becoming too powerful. So, they send their best assassins and warriors after Naruto.

There could be a group of anti - hybrid fanatics. They believe that the existence of a Naruto - Ichigo descendant is an abomination that goes against the natural order of both worlds. They form a secret society and start causing chaos, trying to eliminate the descendant. Their leader could be a former ninja who lost his family in a war and blames the mixing of powers for all the world's problems. They would be a complex antagonist as they have their own warped ideology to drive their actions.

The main antagonist could be a power - hungry shinobi within the same village as the descendant. This shinobi believes that they are more worthy of Hashirama's power and legacy. So, they scheme behind the scenes to undermine the descendant, spread false rumors about them, and even try to set up situations where the descendant would lose their life so that they can claim the power for themselves.

It could be a rogue ninja who wants to use the descendant for their own power - gain. Maybe someone who believes that by controlling the descendant, they can access Kaguya's ultimate power. For example, a power - hungry ninja who has been researching Kaguya's secrets for a long time.

It could be a powerful ninja who has become corrupted by the idea of the descendant's powers. He wants to steal those powers for himself to gain ultimate control over the ninja world. Maybe he has a deep - seated envy of the unique combination of abilities the descendant has.

It could be a rogue Uchiha who feels threatened by the descendant's claim to Izuna's legacy. This Uchiha might think that the descendant is unworthy or that they are trying to steal the spotlight from the main Uchiha line.

One possible plot could be that the descendant has unique powers combining Naruto's ninja abilities and Moka's vampiric traits. He might struggle to fit in both the ninja world and the world related to Moka's origin, facing challenges from both sides who are suspicious of his mixed heritage.

Perhaps a group of pure - blood supremacists could be the main antagonists. They see the Peverell descendant as a threat to their ideas of a pure - blood - only wizarding world. They might try to undermine the descendant at every turn, spreading false rumors and trying to isolate them from the rest of the wizarding community.

It could be someone from the Naruto universe who doesn't like Naruto's newfound fascination with Aku. For example, Danzo might see Naruto's interest in Aku as a threat to the stability of the village and try to stop Naruto from further exploring Aku - related things. So, Danzo could be the main antagonist in this case.
