Naruto would probably be initially shocked and on guard. He's used to all kinds of strange things in his world, but a Fem Predator would be something entirely new. He might try to talk to her first, asking who she is and what she wants. If she showed any signs of aggression, he'd be ready to fight, using his Rasengan or other jutsu. But if she seemed peaceful, Naruto would be curious and want to learn more about her, maybe even offer her some ramen to break the ice.
Maybe the Fem Predator's homeworld is facing a threat that can only be countered with the power of the ninja world. She travels to the Naruto universe to seek help. Naruto volunteers to assist her. As they journey to her world, they face many challenges. Naruto uses his ninja skills and the Fem Predator uses her advanced technology and hunting skills. During this time, they learn from each other's cultures and develop a mutual respect, which ultimately helps them save the Fem Predator's world.
Naruto would probably be very curious. He's always open to new things and new people. He'd likely ask her a ton of questions about where she's from and what she can do.
Naruto would probably be very confused at first. He trusts Sasuke, even if it's a Fem Sasuke in this fanfiction, and he wouldn't expect to be kidnapped by her. So, his initial reaction might be to try and talk to her, asking her why she's doing this.
Naruto might initially be shocked. Given his friendly nature towards Sasuke in the original story, he wouldn't expect such an attack from her. So, his first reaction could be pure disbelief.
The villagers' reaction would be mixed. Some would be in awe of Fem Kyuubi's power and her act of saving Naruto. They would see her as a hero and start to change their views on the Kyuubi in general. However, there would also be those who are still fearful. They might think that Fem Kyuubi has some ulterior motives and be suspicious of her. Naruto's friends from his ninja team, like Shikamaru and Choji, would probably be more accepting. They would welcome Fem Kyuubi as long as she proves to be on Naruto's side and doesn't cause any trouble for the village.
The ninja elders in Konoha could see it as a potential threat. They might worry that Fem Naruto leaving could expose Konoha's secrets or that she could be turned against the village by enemies. So, they would start to take measures to protect Konoha's interests. They could send out spies to keep an eye on her or try to find a way to bring her back. On the other hand, the younger generation of ninjas might be inspired by her courage to break free and seek their own paths outside of the village.
He'd probably be super surprised. I mean, seeing yourself as the opposite sex is not something that happens every day. He might blurt out something like 'Who are you? You look like me!' and then start to realize the situation. He could be a bit embarrassed too, especially if female Naruto had some different mannerisms or ways of dressing.
She would probably be very angry at first. Naruto is a headstrong character, and being kidnapped against her will would make her furious. She'd likely try to fight back immediately, using whatever skills she has at her disposal.
Naruto might be initially confused. He is used to being friendly with everyone, and this sudden possessiveness from Fem Gaara could catch him off - guard. So he may just try to talk to her to understand why she is acting this way.
Naruto would probably be very confused at first. He's always seen the Akatsuki as the enemy, so being taken there by Fem Itachi would be quite a shock. He might be on guard and constantly looking for a way to escape.
