Power struggle is a frequent theme. Dark Ichigo often has a different view on how to use Ichigo's power compared to Ichigo himself. Also, the theme of acceptance is there. Sometimes Ichigo has to accept that Dark Ichigo is a part of him in order to move forward. There's also the theme of redemption in some fanfictions, where Dark Ichigo may be redeemed in some way.
One common theme is the battle between good and evil within Ichigo. His normal self represents the good, while Dark Ichigo represents the more primal and sometimes malevolent side. Another theme is self - discovery. As Ichigo grapples with Dark Ichigo, he often discovers new aspects of his own power and personality.
Love and romance are really common themes. Writers often explore how Ichigo, with his tough - yet - caring personality, falls in love with the reader. It could be a slow - burn type of love or a love - at - first - sight kind of thing. And also, the theme of power - sharing or power - combination can be seen. For example, the reader might have some special power that combines with Ichigo's to defeat a powerful enemy.
Another theme is the exploration of power. Dark Ichigo has a significant amount of power, and in crossover fanfictions, it's interesting to see how that power measures up against the powers in other fictional worlds. For example, if he crosses into a world with magic, how does his reiatsu compare to the magic system there? It's all about power dynamics.
One common theme is the struggle between light and dark within Ichigo. Since it's about Dark Ichigo in a harem setting, there's often a battle within him as he deals with his relationships while having this darker side.
Well, I know a fanfiction named 'Twilight of the Ichigo'. In this story, the author vividly depicts the psychological struggle between Ichigo and Dark Ichigo. It also involves some other characters who are affected by this internal conflict. Another fanfiction is 'Eclipse of the Self'. It shows how Ichigo tries to come to terms with his dark side, which is full of twists and turns.
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.
A common theme is the struggle between light and dark. Ichigo represents the light side, while Hollow Ichigo is the dark. Their relationship in yaoi fanfiction often shows how these two opposing forces interact and potentially find a balance. Another theme could be self - acceptance. Ichigo accepting his Hollow side in a more intimate way is often explored.
Love and attraction are quite common. It's about two very different beings being drawn to each other.
One common theme is the power dynamic. Since Ichigo is a powerful Soul Reaper, there could be stories where he protects the reader from Hollows or other threats. Another theme is the discovery of the reader's own hidden powers, with Ichigo guiding them. For example, the reader might be a new Soul Reaper in training.
Friendship is a very common theme. The story might show how Ichigo and the reader meet and gradually become good friends, sharing secrets and having each other's backs. Another theme could be mentorship, where Ichigo teaches the reader about the ways of the Soul Reapers or some other important skills. And of course, there's the theme of adventure, where they embark on exciting journeys together in the Bleach universe.
Another theme is friendship. Given that both characters are known for their strong bonds with their friends in their original series, fanfictions like to explore how they would form a friendship with each other. They might start off as rivals and then grow to respect and trust one another over time.
