Ichigo might become more in tune with his Hollow side as a result of his connection with Halibel. Since she is an Arrancar, her presence could trigger something within Ichigo's inner Hollow. This could lead to new powers or a better control over his Hollow form. Halibel, on the other hand, could develop a softer side. Ichigo's unwavering determination and his respect for life could influence her, and she may start to show more compassion towards others, even those outside of Hueco Mundo.
In the fanfiction, Ichigo could grow in his leadership skills. Working with Halibel, who has her own group of followers in Hueco Mundo, he has to step up and be a more diplomatic figure. He needs to find a balance between his own beliefs and the needs of those around him. Halibel could develop a sense of self - discovery. Meeting Ichigo and being exposed to his different world view could make her re - evaluate who she is and what she wants. She might break away from the traditional Arrancar hierarchy and strive for something more individualistic.
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.
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.
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.
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.
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.
It could mean a new kind of power dynamic. The baby might have abilities that are unheard of, combining the Quincy, Shinigami, and Arrancar powers that are related to Ichigo and Halibel in some ways. This could change the balance in the fictional 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 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.
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.
