One aspect could be the psychological impact on Ichigo. If he's being brainwashed, he might lose his sense of self and his usual heroic nature. His relationships with his friends like Orihime, Chad, and Uryu could also be severely affected. For example, they might not recognize the brainwashed Ichigo and think he's turned against them. This could lead to some really intense and emotional scenes in the fanfic.
A possible plot development could be Ichigo being made to fight against his former allies. Under the brainwashing, he might believe that his friends are actually his enemies. Another development could be Xcution trying to extract Ichigo's power while he's in this brainwashed state.
One thing that can make it interesting is the potential for character growth. Ichigo is already a complex character, but being part of Xcution could expose him to new challenges that force him to evolve. Also, the relationships he forms with the members of Xcution could be very different from what we've seen before. He might have to trust people he's not sure about, or deal with betrayal. All these elements can add depth and excitement to the fanfic.
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.
There's a fanfic called 'The Bond of Hearts'. It's set in an alternate universe where Ichigo and Orihime are childhood friends. It shows their relationship evolving over the years. It delves deep into their emotions and how they gradually realize their love for each other. The character development in this fanfic is quite engaging.
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 He might become more withdrawn and focus even more on his battles and training, using it as an escape from the pain of the betrayal.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.
One great fanfic where Ichigo is injured is 'The Road to Recovery'. It shows how his friends and allies support him during his healing process. The author does an amazing job of portraying Ichigo's struggle with his injury, both physically and mentally.
One possible reason could be to gain more power. In the Bleach universe, the dead often possess unique powers or knowledge. By raising the dead, Ichigo might be seeking to learn from them or use their power to fight stronger enemies.
Uryu could be another supporter. Despite their differences in the past, Uryu has come to respect Ichigo. In this strange situation, he might use his intelligence to help Ichigo. For example, he could research any possible side - effects or solutions related to the mpreg. Orihime is also a strong candidate. She has feelings for Ichigo and would be very empathetic. She would likely offer her healing powers and motherly - like care to Ichigo during his pregnancy.
One character that might betray Ichigo is Chad. In some fanfic scenarios, if Chad is corrupted by some dark force or if he discovers some 'truth' about Ichigo that he believes is a threat to the world, he could turn on him. Also, Orihime has the potential to be a betrayer in fanfictions. If she is brainwashed by an enemy, like a powerful Hollow or an evil Quincy, she could be made to act against Ichigo. Her powers are unique and if misused, could cause a lot of harm to Ichigo.
