Naruto could use his talk - no - jutsu on Queen Chrysalis. He's known for convincing his enemies to change their ways. He might try to make her see the error of her ways if she's being evil in the fanfiction.
They could fight at first. Naruto would use his ninja techniques like rasengan, while Queen Chrysalis would use her magic or her ability to transform. But then, they could realize they have a common enemy and team up.
In a fanfiction, Queen Chrysalis could be interested in Naruto's chakra. She might try to steal it to increase her own power. Naruto would have to defend himself and in the process, he could teach her about the importance of having your own power rather than stealing it from others. This could lead to a change in her character over time as she starts to respect Naruto's values.
One idea could be a crossover where Naruto is transported to the world of Queen Chrysalis. He might initially be seen as a threat but then tries to find a way to coexist or help the creatures in that world. Maybe he uses his ninja skills to protect them from other threats.
Naruto might be very energetic and friendly towards Thea Queen Lemon. He would probably greet her with his big smile and introduce himself. Thea Queen Lemon could be initially a bit reserved but Naruto's openness would gradually make her more comfortable.
Naruto would probably be very curious about the Dragon Queen. He'd be excited to see her dragons and might try to befriend them. The Dragon Queen, on the other hand, would be cautious at first. But Naruto's friendly nature and his display of powerful ninja skills could earn her respect. They'd likely have conversations about their different worlds, with Naruto talking about his friends in the Hidden Leaf and the Dragon Queen about her claim to the Iron Throne.
They could also have a mentor - mentee relationship in a way. Naruto, with his experience in combat and growth, could offer advice to Ophis on how to better control her power. Ophis, with her knowledge of the DxD world's magic and power systems, could teach Naruto some new skills or ways to enhance his chakra. This exchange of knowledge and experience would create a unique dynamic between them.
In a more in - depth interaction, if Clayface were to get injured in the Naruto universe, Naruto could offer to help him. Naruto's knowledge of medical ninjutsu might be able to heal Clayface in some way. This would create a bond between them as Clayface would be grateful. They could then exchange stories about their respective worlds, with Naruto telling Clayface about his life as a shinobi and Clayface sharing his experiences in Gotham.
Naruto could be initially attracted to Frostmourne's power. He might touch it and start to feel a strange connection, but then quickly realizes the danger it poses.
In the fanfiction, Naruto could also team up with other characters from the Dementor - related world. He could combine his ninja techniques with their magic to combat the Dementors more effectively. For instance, he could work with a wizard who knows a lot about Dementors and together they could develop new strategies to keep the Dementors at bay. His ability to make friends and form strong alliances would be very useful in this scenario.
Another option is that it could be a character from a different species entirely. This could create a whole new set of plotlines and conflicts, such as how the two different species will interact because of the pregnancy and what it means for their respective cultures.
They could interact through a mutual respect for each other's powers. Naruto might be in awe of female Aquaman's ability to communicate with sea creatures and control the waters, while she could be impressed by his ninjutsu. For example, Naruto could use his shadow clone jutsu to help her herd a group of unruly sea monsters that are causing trouble near a coastal village.
Naruto's chakra - based powers and Maleficent's dark magic could either clash or combine. For example, Naruto could use his Rasengan, and Maleficent could add her dark magic to it, creating a super - powerful attack. Or their powers could be in opposition, like Naruto's life - affirming chakra against Maleficent's death - dealing magic.
