One possible fanfic could be where the fullbringers use some sort of spiritual power to brainwash Ichigo. Maybe they want to turn him against his friends in Karakura Town. They could manipulate his memories of his battles and his relationships, making him believe that his friends are actually his enemies. This would lead to some really intense fight scenes as his friends try to break the brainwashing and bring Ichigo back to his senses.
Perhaps the fullbringers are being controlled by a new, unseen enemy. This enemy wants Ichigo out of the picture, so they use the fullbringers to brainwash him. Ichigo, while brainwashed, starts to cause destruction in the Soul Society. His actions draw the attention of the Soul Reapers, who are initially unaware that he's been brainwashed. As the story progresses, some of the more perceptive Soul Reapers figure out what's going on. They then team up with Ichigo's friends from Karakura Town to find a solution. This could involve a lot of exploration of Ichigo's mind and his past relationships to find the key to breaking the brainwashing.
Ancient Ichigo in strong Ichigo fanfics is different from regular Ichigo in several ways. For one, his power might be more raw and primal. Regular Ichigo has developed his powers over time in the canon story, but ancient Ichigo's power could be something that was inherent from the start, less refined but more powerful in a different sense.
Kisshu and Ichigo are likely characters from a particular anime or manga series. They are the main focus in this fanfiction where the situation of pregnancy is involved.
One of the main attractions in Hollow Ichigo x Ichigo yaoi fanfiction is the exploration of their psychological connection. Since Hollow Ichigo is a part of Ichigo, it's like a self - exploration but in a more romantic or sexualized way in yaoi. The fanfiction might show how their relationship evolves from a state of conflict, where Ichigo is constantly fighting against Hollow Ichigo, to a more harmonious or at least an understanding one. This can be really appealing to readers who are interested in character development within the framework of a non - traditional relationship.
Well, one aspect could be the exploration of the relationship dynamic between Ichigo and the female Hollow Ichigo. It might delve into how their opposing natures interact, like Ichigo's heroic side and the Hollow's more chaotic nature. It could also show how they influence each other's growth in the fanfiction world.
At the start, Ichigo would be defiant. He would not show any fear in front of Aizen. He might taunt Aizen, trying to get him to reveal his true intentions. As time goes on, he would start to feel a sense of isolation, but this would only strengthen his resolve. He would use his inner Hollow powers more freely, as he has no other option. He would also be constantly thinking about ways to turn the tables on Aizen and escape, and would be ready to take on any challenges that come his way during his captivity.
A common theme is the exploration of their dual natures. Since Ichigo has his own powers and the female hollow ichigo has her unique hollow characteristics, fanfictions often play with how these two different yet connected aspects interact.
Ichigo would probably be devastated. His trust in relationships would be severely shaken. He might become more withdrawn and focus even more on his battles and training, using it as an escape from the pain of the betrayal. He could also become more cynical about love and people in general.
