Perhaps in this fanfiction, an evil force has a plan that involves Azula getting pregnant with Naruto's child. The two initially don't get along but as the pregnancy progresses, they start to understand each other better.

And they work together to protect their unborn child from the evil force.
Well, one possibility could be that Naruto, with his ninja skills and sense of justice, has to protect Azula in a world where the Fire Nation is facing a new threat.

He'd also try to understand Azula's complex personality and help her become a better leader in the process of protecting her.
The plot could involve Naruto and Azula discovering their relation later in life. Naruto, being from a different world, would have to adapt to the Fire Nation's culture. Azula might initially be hostile towards Naruto, seeing him as a threat to her power. However, as they interact more, Naruto's unwavering belief in people's goodness starts to chip away at Azula's cold exterior.
One possible plot could be that Naruto, through some kind of interdimensional rift, ends up in the Avatar universe where he encounters Azula in a dire situation.

He uses his ninja skills like shadow clones and rasengan to fight off the captors and saves Azula. Then, Azula, initially distrustful, gradually comes to respect Naruto as they face more challenges together in this strange new world.
One possible plot could be that it's an alternate universe where Naruto and Tenten end up together in a situation that leads to pregnancy.

The plot could be that Naruto and Mei are in a secret relationship. When Mei gets pregnant, they try to keep it a secret at first. However, as the pregnancy progresses, it becomes harder to hide. Mei starts to show signs of a special chakra within her womb, which makes some villains target her. Naruto has to fight off these villains while also dealing with his own insecurities about becoming a father. They finally decide to reveal their relationship and Mei's pregnancy to their closest friends and allies, who then rally around them to protect them and the unborn child.
One possible plot could be that Naruto and Cana are from different worlds that somehow collide. They meet and fall in love. When Cana discovers she is pregnant, they face challenges from their respective communities. Naruto's ninja world might be against the union due to Cana being from a different realm, and Cana's side might have issues with Naruto's ninja lifestyle.
One possible plot could be that Naruto and Shion's relationship develops gradually. Shion discovers she's pregnant and they face challenges together. For example, they might have to deal with the reactions of their friends and the village. Naruto would be protective, using his skills to keep Shion and the unborn child safe from any threats.
One possible plot could be that they accidentally get caught in a jutsu that causes Konan to become pregnant. Naruto, being the responsible person he is, decides to support her fully. They might face challenges from their respective villages as their relationship was unexpected. Konan may have to deal with the physical and emotional changes during pregnancy while Naruto tries to protect her from any harm.
Well, it could be about Naruto having some of Azula's traits. Maybe he has her strategic mind. For example, in battles, he could use her style of planning and outwitting opponents. And perhaps he has some of her fire - bending - like abilities translated into his ninja skills, like really powerful and precise fire - style jutsu.
A plot could involve the challenges they face during the pregnancy. Maybe there are threats from old enemies who see the baby as a potential target. Naruto and Temari then have to take extra precautions to protect themselves and the unborn child. They could also go on a journey to find a special kind of medical ninja who can ensure a safe pregnancy for Temari, especially if there are some complications due to her being a ninja. Along the way, they might discover new things about each other and grow even closer as a couple.
