Who might be the main antagonist in the 'sakura wears a masklike kakashi fanfiction'?

Perhaps in this fanfiction, Sakura wearing the mask - like Kakashi is a symbol of her growth. She might be emulating Kakashi's calm and collected demeanor. It could start with her being inspired by Kakashi's success in various missions. So, she decides to wear a similar mask to see if she can also gain an edge in her own missions, both in terms of physical combat and mental strategy.

It could be Orochimaru. He might be interested in the baby for some dark experiment, thinking the baby has unique chakra or abilities that he can use for his own gain. He would stop at nothing to get his hands on the baby, which would put Kakashi and Sakura in a tough situation to protect it.

Kakuzu might also be a main antagonist in this fanfiction. He's always after money and power. Maybe he sees Sakura as a valuable asset, either to sell her back to Konoha for a large sum or to use her skills for his own gain. He's not very empathetic and would likely be ruthless in his treatment of her.

It could be Orochimaru. He's always had an interest in powerful shinobi, and Sakura has shown great potential. Itachi might be roping Sakura's wrists to prevent Orochimaru from getting to her and using her for his evil experiments.

Perhaps an old enemy of Sasuke's family, someone who holds a grudge against the Uchiha clan. They might see the new baby as a continuation of the Uchiha line and try to end it. This would put Sakura and Sasuke in a difficult situation where they have to use all their skills and the help of their friends to protect their baby.

Itachi himself could be seen as the main antagonist in this scenario as he is the one performing the kidnapping. His actions are against Sakura's will and are likely to cause distress and conflict.

Perhaps there is no traditional antagonist. Instead, Naruto's own insecurities could be the 'antagonist'. He's so used to wearing the mask of the happy - go - lucky guy that his inner self is resistant to being exposed. So, in a way, his own fear of change and vulnerability is what Sakura has to fight against when she tries to break his mask.

Perhaps an old enemy of Naruto's who resurfaces and decides to target his family. This could be someone who was defeated by Naruto long ago but has now grown stronger and wants to cause harm to his loved ones. They might also see Kakashi as a threat in protecting the family.

It could be Orochimaru. He might be interested in the unborn child for some dark experiment, thinking that the child of Kakashi and Rin could possess some unique abilities. He could send his minions to spy on them or even try to kidnap Rin.

It could be Orochimaru. He might see the baby versions of Team 7 as perfect subjects for his experiments. He could try to kidnap them to use their unique chakra or potential for his own dark purposes.
