Well, there are themes related to discovery. Characters may discover new things about themselves, their powers, or the other world they encounter. And there's also the theme of adaptation. How do the characters adapt to the new rules and cultures of the other universe? For instance, a Blue Beetle character in Hogwarts would have to adapt to the magical society's norms and vice versa.
Sure. The beauty of fanfiction is that it allows for all kinds of wild combinations. In some 'Harry Potter Blue Beetle' fanfics, the Blue Beetle suit could be enchanted in some way by the magic of the Harry Potter world. Maybe it gains new abilities or has to be protected from dark wizards. It's a great opportunity for authors to explore new storylines and character interactions.
One common theme is adventure. The reader often gets caught up in Blue Beetle's exciting superhero world. Another is romance, as the relationship between the reader and Blue Beetle is a central focus. And there's also the theme of self - discovery, where both the reader and Blue Beetle might learn something about themselves through their interactions.
The idea of Blue Beetle's origin story is also a common theme. Writers might expand on it, or give it a different twist. For example, they might explore how he got the Scarab in more detail. His growth as a hero, both in terms of his powers and his character, is also often written about. He starts as a bit of an outsider in Young Justice, so his journey to fit in and become a respected member is a popular topic.
One common theme is the combination of power. The magic from Harry Potter and the power of hope from the Blue Lanterns often come together. For instance, a character might use a spell while also drawing on the Blue Lantern energy to make it more powerful.
A common theme is adventure. Since Blue Beetle is often involved in heroic deeds, the reader gets to be part of those exciting adventures in the fanfic.
Adventure is also prevalent. Writers often send them on various missions together. For example, they could be on a quest to stop a new super - villain that's causing chaos in the city. These adventures allow the characters to show off their powers and personalities, and also give room for their relationship to develop further.
One common theme is the OC being a sidekick or partner to Blue Beetle in his superhero adventures. Another is a romantic relationship developing between the OC and Blue Beetle.
One common theme is the clash of different magical systems. Harry Potter has its own kind of magic with wands and spells, while Blue Exorcist has exorcism techniques. Another theme is friendship. Characters from both series often form new friendships or have to deal with differences in how they view friendship. For example, a Hogwarts student might be more used to having friends within their own house, while in Blue Exorcist, friendships are formed based on different criteria at the True Cross Academy.
A frequent theme is the idea of characters from different worlds coming together. For instance, Harry Potter and Rin Okumura might meet and form an alliance. Another theme could be the exploration of good and evil in both universes. In 'Harry Potter', there are dark wizards, and in 'Blue Exorcist', there are demons. Fanfictions might show how the characters from each world deal with the concept of evil. Also, the theme of friendship across different magical realms is quite common, as characters build relationships despite their different backgrounds.
Another theme is his relationships, like his family relationships. His family often plays an important role in fanfics, as they are a big part of his life in the original story. And of course, there are also romantic relationships explored in many fanfics, whether it's a new character or an existing one from the Blue Beetle universe.
