What would a fanfic where Ichigo is Aizen's son be like?

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.

Ichigo would likely be defiant. He's a fighter and would not easily submit to Aizen. He'd probably be constantly looking for a way to escape and would be sizing up Aizen's every move, trying to find a weakness.

You can try searching on popular fanfic platforms like Fanfiction.net or Archive of Our Own. Just use the keywords 'Aizen - Obsessed Ichigo Rukia' in their search bars, and you might find relevant fanfics.

In an 'Aizen hypnotizes Ichigo' fanfic, the plot could start with Aizen having some grand scheme that requires Ichigo's cooperation, which he obtains through hypnosis. Ichigo might be made to believe that he is on Aizen's side and is working towards a 'greater good'. Meanwhile, characters like Rukia or Urahara could suspect something is wrong with Ichigo. As the story progresses, there could be a series of battles and mind - games as the good guys try to rescue Ichigo from Aizen's control. There could also be some exploration of the nature of hypnosis in the Bleach universe and how it affects Ichigo's psyche.

Aizen might be motivated by power. Ichigo has a very unique power set that Aizen may want to harness for himself. And Rukia, being from Soul Society, could be used as a way to gain information or leverage against Soul Society.

A fanfiction with this plot would be quite a departure from the normal Bleach narrative. It could involve a lot of world - building to explain how such a thing could even be possible. For example, it might introduce some new supernatural elements or ancient curses. The story would also need to deal with the reactions of other characters in the Bleach universe, like Ichigo's friends and family, and how they would respond to this strange and scandalous situation. It would be a very different take on the characters and the story as a whole.

Rukia would be extremely shocked and disappointed. She has always seen Ichigo as a force for good, and seeing him side with Aizen, who is the main antagonist, would be a huge blow to her. She might try to talk Ichigo out of it at first, and if that fails, she could become his enemy.

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.

One idea could be that Aizen kidnaps them to use Ichigo's power and Rukia's knowledge of Soul Society for his own dark plans. He might want to study Ichigo's unique Hollow - Shinigami powers up close and use Rukia as a bargaining chip with Soul Society.

One common theme is the power struggle. Since Aizen is a very powerful character, and Ichigo (even as a female version) has her own strength. Their interactions often involve a push - and - pull regarding power. For example, in many fics, the female Ichigo tries to resist Aizen's control.
