What are some popular themes in Ichigo and Halibel Fanfiction?

For Ichigo, he could develop a more nuanced view of the Arrancars. Through his interactions with Halibel, he might realize that not all Arrancars are pure evil. This could make him more open - minded in his future encounters with other Hollows. As for Halibel, she could start to see the value in the Shinigami way, especially Ichigo's sense of justice. It might make her question her own loyalties and purpose.

One common theme could be the exploration of their unique relationship. Since they are from different 'worlds' in the original context, fanfiction might play with how they interact and understand each other.

One common theme is power struggle. Given that both characters are quite powerful in their own rights, fanfictions often explore how they deal with each other in terms of strength. Another theme could be the exploration of the dark side of their personalities, as Hollow Ichigo is, well, hollow, and Halibel has her own complex nature.

Another theme could be the exploration of their different worlds. Ichigo is from the human world and Soul Society, while Halibel is from Hueco Mundo. Fanfictions might delve into how they bridge the gap between these two very different realms, perhaps through mutual understanding and cooperation. This can lead to interesting stories about cultural exchange in a sense, within the 'Bleach' universe.

There's also 'Love in the Rukongai'. In this fanfiction, Ichigo and Halibel meet in the Rukongai and gradually develop feelings for each other. It's interesting because it shows a side of their relationship that we don't often see in the original series, with them learning about each other's pasts and growing closer.

One possible plot could be that Ichigo and Halibel initially struggle to understand each other's worlds. Since Ichigo is from Karakura Town and Halibel is from Hueco Mundo. But as they spend more time together, they start to learn about each other's values and dreams. They might face opposition from their respective groups, like Ichigo's friends might be skeptical about his relationship with a former Arrancar. However, through their love, they gradually break down those barriers and build a new life together, perhaps even uniting the two worlds in some small way.

In fanfiction, the idea of Ichigo and Halibel having a baby can lead to very interesting stories. It would combine the unique powers and personalities of both characters. For example, the baby could inherit Ichigo's Shinigami powers and Halibel's Arrancar abilities, creating a truly powerful and unique being. This concept could also explore how the two different worlds they come from, the Soul Society and Hueco Mundo, would react to such a union.

Maybe in the fanfiction, Ichigo gets lost in Hueco Mundo and Halibel finds him. Instead of attacking, she decides to help him find his way back. During their journey, they encounter various challenges and secrets about Hueco Mundo are revealed to Ichigo through Halibel. This could lead to a new understanding between the two species they represent.

Perhaps a plot where Ichigo accidentally ends up in Hueco Mundo near Halibel's territory. She initially sees him as a threat but then discovers that he has no intention of harming her or her fracciones. This could lead to an exploration of their different worlds and cultures within the Bleach universe.

One plot idea could be that Ichigo and Halibel are forced to team up against a new, powerful enemy that threatens both their worlds. They start off distrusting each other but gradually learn to respect and rely on one another's strengths.
