The contrast between Ichigo and Halibel makes it interesting. Ichigo is a hot - blooded and impulsive hero, while Halibel is more reserved and calculating. Their different personalities can create a lot of tension and drama in a fanfic.
There are quite a few 'ichigo x halibel' fanfics out there. Some focus on the power dynamics between them. For example, 'Power and Passion' shows how their different powers interact and how they come to respect each other's strength. It also delves into the cultural differences between their respective races in the Bleach universe and how they overcome those differences to form a connection.
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.
Well, it depends on what you consider 'good'. There are many out there, but the quality varies. Some might focus more on the action and power dynamics between Hollow Ichigo and Halibel, while others could explore a more emotional or romantic side of their relationship. It's best to read the summaries and reviews to find one that suits your taste.
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.
A big challenge would be trust. Given their backgrounds as former enemies, it would be hard for them to trust each other at first. There could also be cultural differences between them. Ichigo comes from a more human - influenced world in the Soul Society, while Halibel is from the harsh and different world of Hueco Mundo. These cultural differences could lead to misunderstandings and arguments as they try to cooperate. Additionally, there could be external forces trying to keep them apart, like other Arrancars or Soul Reapers who don't want to see them together.
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.
Their powers could be combined in a way where Ichigo's Zanpakuto spirit, Zangetsu, and Halibel's water - based powers merge. For example, Ichigo could gain the ability to use water - enhanced slashes that have the cutting power of his normal attacks along with the fluidity of Halibel's water attacks.
Romance is also a common theme. Writers like to imagine a relationship between Ichigo and Halibel, which can be a really interesting take considering their different personalities and allegiances in the original story. It can range from a slow - burn relationship to a more sudden and passionate one.
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.
