Fanfic about Ichigo joining Aizen in Bleach: What could be the plot?

Well, it could be about their adventures together after the main events in Bleach. Maybe they go on a mission to a new realm and face new enemies while strengthening their bond as friends and comrades.

Maybe Aizen has created a false asylum as part of a new experiment. He lures Ichigo and Rukia into it, and they have to find a way to escape while also dealing with the illusions and traps Aizen has set up. In the process, they could learn more about Aizen's motives and past, and perhaps even find a way to defeat him once and for all.

Yes, there are likely some fanfics with this concept. Fanfic writers often come up with unique and sometimes out - of - the - box ideas. However, this goes against the original storyline of Bleach where there is no such relation between them in the official canon.

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.

Well, one possibility is that Aizen somehow convinces Ichigo that his way is the only way to protect his friends. Maybe he shows Ichigo a false future where all his friends die if he doesn't side with Aizen. Ichigo, being desperate to save them, might then join Aizen, thinking he can change things from the inside.

In this fanfic, perhaps it focuses on the friendship between Chappy and Ichigo. Chappy might help Ichigo in some unexpected ways. For example, Chappy could use her unique abilities to guide Ichigo through a difficult part of Hueco Mundo. Their bond could also be a source of strength for Ichigo during tough battles, giving him an extra boost of motivation.

Well, it could be about Ichigo's journey within Xcution. Maybe it shows how he struggles to understand their motives and powers. He might form new alliances or face new enemies while being part of Xcution.

One possible plot twist could be that Aizen has a hidden motive other than just causing chaos. Maybe he kidnaps Ichigo to use his unique powers for some sort of experiment. For example, he might want to extract the power of Ichigo's Hollow side to enhance his own strength or create a new type of Arrancar. Another twist could be that Aizen is being controlled by an even greater force, and Ichigo's kidnapping is part of a larger plan to draw out other powerful characters in the Soul Society.

The Soul Reapers in the Soul Society would see Ichigo as a major threat. They would likely mobilize their forces to either capture or eliminate him. Captains like Byakuya would be disappointed as he had come to respect Ichigo to some extent, and now would see him as a traitor.

Well, one possible plot twist could be that Tsukishima's brainwashing of Ichigo is part of a larger plan by a hidden villain. Maybe this villain wants to use Ichigo's power for some evil purpose. Tsukishima might be forced to do this brainwashing against his will in some way.
