Who could be the main antagonist in a 'naruto and naruko clone fanfiction'?

A possible main antagonist could be a powerful alien who sees Naruto as an abomination. This alien might come from Krypton and believe that Naruto, as a clone of Superman, is a perversion of their species' power. The alien would have all the typical Kryptonian powers but with a more malevolent intent. He would try to destroy Naruto and the Hidden Leaf Village, thinking that he is doing a service to the universe by eliminating this 'false' Superman.

It could be Orochimaru. He might see the potential in the crow clones and try to manipulate them for his own evil purposes, like using them to carry out his experiments or to infiltrate Konoha.

It could be a rogue ninja who has a special ability to disrupt shadow clones. This antagonist might be jealous of Naruto's ability to use shadow clones for training and wants to stop him. Maybe he has a jutsu that can make Naruto's clones go berserk and attack him instead of following his commands.

It could be a rogue ninja who doesn't believe in compromise. This ninja might be causing trouble in the village, and Naruko has to find a way to deal with them. Since the rogue ninja is so set in their ways, Naruko has to make compromises in her approach to fighting them, like using non - lethal force when she might prefer a more aggressive method.

It could be Orochimaru. He's always been interested in power and new forms of jutsu. Seeing Naruto with Superman - like powers would make him want to either steal those powers for himself or find a way to use Naruto as a tool in his experiments.

It could be a rogue ninja from a forgotten clan who wants to steal the unique powers of Naruto, Naruko, and Satsuki. He sees their combined potential as a threat to his own evil plans of taking over the ninja world. This antagonist might have some ancient and powerful jutsu that the three heroes have to figure out how to counter.

They can start by simply spending time together. For instance, going on missions side by side. This allows them to get to know each other's fighting styles and personalities better. As they face challenges during these missions, they start to rely on each other more.

The relationship could develop through shared experiences. For instance, they might go on a mission together where they have to rely on each other to survive. Naruto could see the Naruko clone's determination and courage, and she could see his kind heart. This mutual admiration could lead to a deeper emotional bond. Another way is through Naruto teaching the Naruko clone about things she doesn't understand, like the history of the village or certain jutsu. This teacher - student dynamic can slowly transform into a romantic relationship as they get closer.

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.

Anakin could also face an internal antagonist in the form of his own dark side. The pressures of the Clone Wars, his fear of losing Padmé, and his growing power could all contribute to his inner struggle. This internal battle could be personified as an antagonist that constantly tries to sway him to make wrong choices.
