A theme of discovery could also be explored. The human could discover the existence of the female raptor and her species, and together they could explore the secrets of their shared world. This could include finding hidden places, uncovering ancient artifacts, or understanding the magic or science that binds their world together. All these themes can create engaging and positive fanfiction stories without any inappropriate content.
I'm not aware of any such fanfiction. Fanfiction often involves various themes, but the idea of a female raptor and human in a 'lemon' context (which often implies inappropriate or adult - themed content) is not a common or acceptable genre in mainstream fanfiction communities.
One possible theme could be loyalty. Given their history together in the Soul Society, a fanfiction could explore how their loyalty to different ideals or people affects their relationship. Another theme might be redemption. If there was some sort of falling - out between them in the past, a story could be about one or both of them seeking redemption in the eyes of the other.
One possible theme could be friendship. The human and the female raptor could form an unlikely bond, perhaps the raptor is injured and the human helps it, and they become friends. Another theme could be adventure. They might go on adventures together, exploring new lands or facing challenges. Or it could be about co - existence, how they learn to live together in a world that is not used to such a pairing.
One possible plotline could be their adventures together before joining the Akatsuki. It could show how they discovered their powers and how they started to form a bond. Another plotline could be about their efforts to rebuild Amegakure after the war. They could be shown working together to bring peace and prosperity to their village.
One possible plotline could be that the male human is a scientist studying the raptors and forms an unexpected bond with the female raptor. Another could be in a post - apocalyptic world where the male human and female raptor have to team up to survive against other threats.
Often, the fanfictions might revolve around how Mikoto's presence could have affected the relationship between Naruto and Sasuke. Since Mikoto was Sasuke's mother, she could have played a part in bridging the gap between the two. Also, the theme of Mikoto passing on some of her unique skills or abilities to Naruto is quite common in these fanfictions.
Fanfiction should focus on positive, ethical and consensual relationships. We should stay away from any form of inappropriate and offensive content.
One common theme could be the struggle of the hybrid to fit in. Whether it's in a human society that may fear or misunderstand the raptor side, or in a raptor - like environment where the human traits seem out of place.
One common theme is Sasuke's search for power and how it affects his relationships. For example, in many fanfictions, his pursuit of power makes him question his bond with Naruto. Another theme is his family. Fanfictions often explore how the memory of his family shapes his actions and decisions. Also, his return to Konoha and how he is received by the villagers is a popular theme.
The themes often include Dobby's role as an unlikely hero. He may use his knowledge of the wizarding world's secrets, especially those related to the Malfoys, to assist Harry. Also, the friendship between Harry and Dobby is a big theme. They come from very different backgrounds, yet they form a strong bond. Dobby's selfless acts for Harry, like bringing him the gillyweed in 'Goblet of Fire', are often explored in fanfiction.
