One possible fanfic could involve Toshiro's internal struggle as he starts to turn into a Hollow. Maybe it begins with an encounter with a powerful Hollow that infects him in some way. His friends in the Soul Society might initially not notice the change, but as time goes on, he starts to exhibit strange behavior like increased aggression and a change in his reiatsu.
Ulquiorra Cifer is often a popular character. His cool and somewhat mysterious demeanor in the original series makes him a great subject for fanfiction. Writers like to explore his inner thoughts and emotions more deeply, especially his relationship with Orihime.
The interaction between Hollows and other characters in the 'Bleach' universe is also a great concept. Some fanfictions might focus on how Hollows interact with Soul Reapers in non - traditional ways, like forming alliances or having complex relationships that go beyond the typical predator - prey dynamic.
Well, in a possible love story, Hollow Ichigo could fall in love with an unexpected soul. Maybe a Quincy who initially saw him as an enemy. But as she got to know the conflict within Ichigo, the part that was Hollow Ichigo, she started to see his struggle and the raw power was somewhat alluring. And Hollow Ichigo, for the first time, felt a connection that wasn't just about power or destruction.
Another great one is 'Hollow Ichigo's Redemption'. This fanfic explores the idea of Hollow Ichigo finding a sense of purpose beyond just being Ichigo's other half. It shows a more complex side to the usually chaotic Hollow Ichigo.
The crossovers also allow for unique character interactions. Characters from two very different universes get to meet and interact. This can lead to some really interesting dialogues and relationships. For example, Sasuke might interact with Rukia and they could learn from each other's combat styles and philosophies.
Maybe a fanfiction where a Hollow dragon forms an unexpected alliance with a group of Quincy. The Quincy initially want to use the dragon's power for their own purposes, but as the story progresses, they realize that the dragon has its own motives and a complex personality. They then have to decide whether to continue the alliance or turn against the dragon.
One interesting 'harry potter bleach hollow fanfiction' could be those that explore the concept of magic from 'Harry Potter' in the context of the afterlife or spiritual world similar to 'Bleach' Hollows. For example, a story where a character from 'Harry Potter' has to face off against a Hollow - like entity with their magic. However, it can be a bit niche, so you might have to dig deep in fanfiction websites like FanFiction.net or Archive of Our Own.
A common theme is the clash of different power systems. The magic of 'Harry Potter' and the spiritual powers related to Hollows in 'Bleach' often collide or interact in interesting ways. For instance, how a wizard's spell would fare against a Hollow's attack. Another theme could be the exploration of different afterlife concepts. 'Bleach' has a very detailed afterlife structure, and when combined with the 'Harry Potter' world, it can lead to some thought - provoking ideas about death and the beyond.
