Their relationship might start off rocky. Xanxus is a tough character, and the female Tsuna would probably be a bit intimidated at first. But as he teaches her and protects her, she would start to see his good side. They could develop a father - daughter - like relationship, where Xanxus is the strict but caring father figure.
At first, Xanxus may see the female Tsuna as a nuisance. However, as time passes, he realizes her potential and starts to respect her. She, on the other hand, would come to understand Xanxus' motives and the reasons behind his harsh exterior. This mutual understanding could lead to a deep and loyal relationship, perhaps like that of a mentor and a protege.
Maybe in the fanfic, Xanxus raises the female Tsuna in a world where the Vongola family is facing a new and unknown threat. Xanxus, with his rough and tough attitude, has to soften a bit to be a proper guardian for her. He might teach her combat skills as well as the politics within the mafia world, and she could in turn change his perspective on certain things.
Tsuna would likely develop a sense of wariness towards Xanxus. He might start to train harder to be able to stand up to Xanxus if he ever becomes a threat again. For Xanxus, he could start to see Tsuna as a more interesting opponent rather than just a nuisance. He might become more observant of Tsuna's growth, which could lead to a more complex relationship between them.
In the beginning, Captain Marvel may be a bit strict in raising Peter, but that's because she wants him to be a great hero. Peter might rebel a bit at first. However, as they face challenges together, they would understand each other better. Captain Marvel would see Peter's potential and kindness, and Peter would see her as more than just a powerful being. Their relationship would develop into a deep, loving connection that would be the heart of the fanfic.
At first, it would probably be very difficult. Tom is a complex character with a lot of pride. Harry, on the other hand, has a deep - seated hatred for Voldemort. But as Harry gets to know the young Tom, he might start to see him as a lost child. Their relationship could slowly shift from one of suspicion to a more paternal - like bond as Harry tries to mentor Tom.
Their relationship would likely start with Poseidon being a strict but loving father. He would teach Percy the ways of the sea and the power that comes with being a son of Poseidon. As Percy grows, they might have some disagreements, for example, about how Percy should use his powers in the mortal world.
The plot could start with Hanzo finding Naruto in a difficult situation, like after a battle or lost in a dangerous area. Hanzo decides to take care of him. As Naruto grows under Hanzo's guidance, he might face challenges from Hanzo's enemies who see Naruto as a potential threat or an easy target. Naruto would have to prove himself and learn to protect himself and Hanzo's territory.
One common theme is the idea of opposites attract. Female Tsuna is often depicted as kind and gentle while Xanxus is tough and brash. Their differences draw them together in these stories.
One common theme is the idea of redemption. Xanxus is often portrayed as a rather rough character, and in these fanfictions, he might find a way to redeem himself through his interactions with Tsuna.
At first, their relationship might be rocky. Snape is known for his harshness and Hermione is headstrong. But as time passes, they would start to understand each other better. Snape would see Hermione's thirst for knowledge and Hermione would see Snape's hidden kindness. Eventually, they could form a bond like that of a father - daughter relationship. Snape would be proud of Hermione's achievements in magic and Hermione would respect Snape's wisdom.
At first, it might be a bit rocky as Naruto is still learning how to be a responsible caretaker. But as time passes, they would become closer. Naruto would share his dreams and experiences with his sister, and she would look up to him. Their bond would strengthen through shared meals, training sessions, and late - night talks.
