A common theme is power struggle. When Naruto is reverse - summoned, often there are those who want to either use his power or take it away from him. Another theme is exploration, as he is usually in an unfamiliar place and has to explore to find a way back.
One common theme is the development of Naruto's relationships with multiple female characters. It often focuses on how he navigates his feelings among them. Another theme is the impact on the Naruto universe's existing power dynamics when Naruto is in a reverse harem situation.
The theme of changing relationships is also prevalent. Naruto may go back and try to improve his relationships with characters who were once distant or hostile towards him. He could use his knowledge of their future selves to build stronger bonds from the start. This can lead to a more united ninja world as he influences those around him in positive ways.
One common theme is power and its implications. When a character gets the kitsune summoning contract, they gain a new level of power. They have to learn to control it and deal with the responsibilities that come with it.
One frequent theme is the discovery of something ancient and powerful. Since the Phoenix summoning contract is not a part of the original Naruto canon in this way, it represents a new and exciting discovery. Also, the theme of transformation is common. The summoner may transform in some ways, either physically or in terms of their abilities, as they grow closer to the phoenix.
One common theme is the exploration of Naruto's connection to the foxes. It often focuses on how he can better utilize the power from the summoning contract.
One common theme is the inversion of good and evil. Since it's about reversing the normal Gravity Falls, characters that were good might be bad and vice versa. For example, Mabel might be a scheming character instead of the sweet girl we know.

Another theme is friendship. Even though it's a reverse harem situation, Hermione's friendships with other characters, like Harry and Ron, still play an important role. The fics usually show how these friendships are affected or enhanced by her new relationships. It's often a balance between romantic love and platonic love.
One common theme could be role - reversal in their personalities. For example, Dipper might be more carefree and Mabel more cautious. Another theme could be exploring a different kind of relationship dynamic between them, like a more romantic - friendship hybrid.
Another theme is the exploration of Harry's character in a different light. In these fanfictions, Harry might be more confident or have different traits compared to the original series.

For instance, they might support each other in dealing with the challenges that come with their shared feelings for Harry. And often, there's a theme of self - discovery for Harry as he navigates these new relationships.
