In a fanfiction, Kaien's daughter might be a key figure in bringing about a truce between the vampires and the vampire hunters. She could grow up with a deep understanding of both sides, having been exposed to the vampire world through her father's connection and the hunter world through her family's legacy. This would lead to her trying to bridge the gap between the two groups, facing many challenges along the way.
She could be a rebel. She might oppose the traditional ways of the vampire hunters or the vampires. For example, if she falls in love with a vampire when she is supposed to be a hunter, it would create a great conflict. This could lead to her being ostracized by her own group and having to find her own path.
One possible story could be that Kaien Cross's daughter discovers she has unique powers in the world of Vampire Knight. She might struggle to fit in among the vampires and humans, while also trying to understand her father's past and his connection to the vampire world.
One great arrancar ichigo fanfiction is 'The Hybrid's Path'. It explores an alternate universe where Ichigo has more complex interactions with the arrancars. Another is 'Ichigo's Arrancar Ally' which focuses on an unlikely alliance between Ichigo and an arrancar against a common enemy. And 'Arrancar - Infused Ichigo' shows Ichigo with some unique arrancar - like powers.
One great arrancar orihime fanfic is 'A Meeting of Souls'. It beautifully explores the relationship between arrancars and Orihime in a unique way. The story has a great plot that keeps you hooked from start to finish.
No. Harry Potter is set in a world of wizards, witches, Hogwarts, and magic that is very much its own. It has elements like the Philosopher's Stone, the different houses at Hogwarts, and the battle against Voldemort. Arrancar, on the other hand, belong to the Bleach universe with a different set of rules, powers, and a very different kind of supernatural world. So, Harry Potter can't be an Arrancar fanfiction.
One interesting concept could be how Ichigo's character might change in the reincarnation and time travel scenario. Maybe he has memories of his past life that influence his actions in the new timeline.
Perhaps a new character created specifically for this fanfiction. This new antagonist could be someone who wants to use the power of reincarnation and time travel for their own evil purposes, like trying to rewrite the world to their liking and is opposed by Ichigo and Kaien.
In these fanfictions, the power system is a key aspect. Naruto, as an Arrancar, would have access to different levels of power, like the release of his Zanpakuto. The story may also involve Naruto having to deal with the inner Hollow, which could add an internal conflict to his character. Additionally, there could be crossovers with other Bleach characters as they are related to the Arrancar concept. This would create new and exciting interactions and storylines.
In arrancar ichigo fanfiction, the exploration of identity is a key element. Ichigo has his own identity as a Soul Reaper, but when he gets involved with the arrancars, he may question who he really is. Is he still just a Soul Reaper, or is he becoming something more? Also, the power - up scenarios are common. Ichigo might gain new arrancar - based powers that are both a boon and a bane. For instance, he could have trouble controlling them at first. And the moral and ethical dilemmas are important. If he befriends an arrancar, how does he deal with the fact that arrancars are often seen as enemies by the Soul Society? These elements add depth and complexity to the fanfiction.
