The fanfiction often combines the magic system from the Harry Potter world with the TF TG concept. So, you get to see how transfiguration spells might be used to create these unique transformations. It also allows for different interpretations of the characters' personalities in their new forms.
Well, there are many. Some focus on TF where characters like Ron might be transformed into an inanimate object for a while. It could be a comical take on the story, with Ron having to figure out how to get back to his normal self while his friends try to help. In some TG fanfictions, Ginny could be transformed into a male character, and this would change the dynamics of her relationships, especially with Harry and her family.
One great Harry Potter TF TG fanfiction is 'The Transfigured Trio'. It has an interesting take on the characters' transformations. Another one could be 'Hermione's New Form' which focuses on Hermione's unique transformation journey in a really engaging way.
Fanfiction.net is also a good place. There are many Harry Potter fanfictions there, and if you specifically search for TG/TF ones, you're likely to find some interesting reads. However, the quality can vary, so it's important to read the reviews or summaries first.
Another feature is the opportunity to explore different versions of the characters. In 'harry potter crossovers fanfiction', authors can take a character like Hermione and give her a completely different backstory or personality. Maybe she's a more rebellious Hermione in a crossover with a dystopian world. This gives readers a fresh perspective on the familiar characters.
One unique feature is the blend of two very different mythologies. Harry Potter has its own European - based magical lore, and tengu comes from Japanese folklore. When combined, it creates a really interesting cultural mix. For example, a tengu's flight ability might be compared to a broomstick in the Harry Potter world.
Often, the unique feature is the exploration of Prongs' character. Fanfics might show his loyalty in more depth, like how he was always there for his friends. For example, in some stories, we see him sacrificing his own interests to protect the others in the Marauders.
Often, 'Invictus' in these fanfictions brings a new perspective on magic. It could be a new form of magic that is related to the unconquerable spirit. Maybe a magic that can only be harnessed by those with a strong will, like the idea behind 'Invictus'. This sets it apart from the more common magic in the original series.
The unique features often include cultural elements. Korean fanfictions may incorporate Korean food like kimchi into the Hogwarts feasts. They might also introduce Korean clothing styles, like having characters wear Hanbok on special occasions. Another feature could be the use of Korean language in spells or incantations, which gives a new and interesting twist to the magic in the Harry Potter universe.
The character interactions are also unique. Harry Potter, who is used to dealing with wizards, witches, and magical creatures, now has to interact with Ophis or things related to Ophis. This can lead to some really interesting dialogue and relationship building. For example, in some fanfictions, Harry might have to learn a whole new way of communicating or respecting a different kind of being, which is very different from his normal Hogwarts experiences.
The settings in 'harry potter kishin fanfiction' are also special. You can have parts of the story set in the familiar Hogwarts, but then there could be new areas or dimensions related to the kishin concept. For instance, there might be a hidden realm where kishin are more prevalent, and the characters have to journey there. This expansion of the setting beyond the normal Harry Potter locations adds a whole new layer of mystery and adventure to the fanfiction.
