A long - lost relative of Sirius Black could be a shapeshifter. Since the Blacks had many secrets and were involved in a lot of dark magic in their family history, it would be believable for a hidden relative to have this unique ability.
Shapeshifter fiction is a genre where the main concept involves characters that can change their physical form. For example, in some werewolf stories, which are part of shapeshifter fiction, a human can transform into a wolf during a full moon. It often explores themes like identity, as the character has to deal with two very different forms and the implications of switching between them.
The Children of the Forest are also common in shapeshifter fanfictions. They are already somewhat mysterious in the original series, and their connection to magic makes them ideal candidates for shapeshifting in fan works. Writers might have them shapeshift into different animals or even blend in with humans to protect their secrets or fight against their enemies.
One great Hermione is a Shapeshifter fanfic is 'The Shapeshifting Hermione'. It has an interesting plot where Hermione discovers her shapeshifting abilities and how it affects her relationships at Hogwarts. The author does a great job of exploring the implications of such a power in the wizarding world.
Another aspect is the unique relationships. Gay relationships in these novels often have an added layer of complexity because of the shifter nature. There can be issues of trust, as one partner may be worried about the other's true form or abilities. Also, the physical aspects of a shifter, like enhanced senses, can impact how they interact romantically.
To write an excellent shapeshifter story, think about the emotional journey of the characters. How do they cope with constantly changing? What internal conflicts arise from it? Also, introduce unexpected twists and turns related to the shapeshifting to keep readers on the edge of their seats.
Hermione would probably be initially shocked but then immediately start researching all she could about animal shapeshifting in the wizarding world. She'd try to find ways to help Harry control his ability and understand it better. Ron, on the other hand, might be a bit more freaked out at first but would soon come around and see it as another cool aspect of Harry. He'd probably joke about it and say things like 'At least we know you can turn into something useful in a fight now!'.
To some extent, it is popular. There are many online platforms where MHA adult fanfiction can be found.
