Ichigo would approach the Hogwarts faculty with an open mind. He might seek out professors like Dumbledore for advice on how to handle the new magical environment while also dealing with his own inner darkness. Dark Ichigo would likely view the faculty as obstacles in his path to power. He might challenge them in a more aggressive way, like trying to outwit them in magical duels or contests of knowledge. However, the faculty, being experienced, would not be easily intimidated by him.
They might have all kinds of adventures. Ichigo could use his Soul Reaper powers in the magical world of Hogwarts. Maybe he'd face off against dark wizards with his zanpakuto. Dark Ichigo, being more chaotic, might get into trouble with the Hogwarts rules and end up in a duel with some of the more hot - headed students.
Obviously, Ichigo and Dark Ichigo are the central characters. Ichigo, with his complex personality and powers, is always a key figure. Dark Ichigo, being his inner Hollow, brings a lot of drama and conflict. The OC also becomes popular depending on how well - written they are. If the OC has unique powers or a really interesting backstory, they can gain a following among fans of the fanfiction.
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.
Another concept could be the origin story of Dark Ichigo within the fanfiction world. It might be different from the original manga or anime, like Dark Ichigo being a result of an ancient curse that the OC is somehow involved in. This could lead to a whole new plotline where Ichigo has to not only deal with his inner Hollow but also the mystery behind it.
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.
One popular trope is the 'enemies to allies' arc. At first, Dark Ichigo and Rukia may be at odds, but as the story progresses, they find common ground. Another is the 'redemption' trope, where Rukia tries to bring out the good in Dark Ichigo. A third one could be the 'mysterious connection' trope, where there seems to be an unexplained bond between them that drives the plot forward.
There are different types of Dark Ichigo and Rukia fanfiction. Some are action - packed, with intense battles between them. These battles can be not only physical but also psychological. Other fanfictions are more character - driven, delving into their emotions and backstories. For instance, a fanfic might explore how Rukia's past experiences in the Soul Society influence her perception of Dark Ichigo. And sometimes, fanfictions might even introduce a romantic element between them, which is a very interesting twist considering their original relationship in the Bleach series.
In fanfiction, Dark Godlike Ichigo may have a more brooding and unpredictable personality. His actions might be driven by a new sense of purpose related to his dark powers. He could also have some new abilities like the power to manipulate shadows or create dark energy blasts.
Well, I read a fanfic called 'Dark Ichigo's Time - Twisted Travels'. In this story, Dark Ichigo travels back to key moments in Ichigo's life and tries to change things for his own dark purposes. It's full of action and some really interesting takes on how the Bleach timeline could be altered. It's definitely worth checking out if you're into this kind of fanfiction.
