In some fanfictions, Harry might be described as having his mother's bright green eyes, which were said to be very expressive. Also, he could have her delicate facial features, like a small nose and a soft jawline. Maybe his hair has the same texture as his mother's, which could be a bit wavy.
Often, in such fanfictions, Fem Harry Potter is described as having Lily's facial structure. Her face might be oval - shaped, just like her mother's. And when it comes to expressions, she might share Lily's warm and friendly smiles. Also, the way she moves could be elegant, much like how one would imagine Lily to move. Her skin tone could be as fair as Lily's too, giving her an overall resemblance.
One way Harry Potter might act like his mother in the fanfiction is through his nurturing side. His mother was a loving and caring person. So, Harry could be seen taking care of his friends when they are sick or in trouble. He might also be very inclusive, making sure that no one feels left out, similar to how his mother would have treated people around her. This could also be shown in his relationships with his Hogwarts classmates, where he goes out of his way to make everyone feel welcome and valued.
It could lead to some interesting plot twists. Maybe people would treat him differently based on his resemblance to Lily.
Well, in such fanfictions, her character development might be more influenced by her mother's traits. Since she looks like her mother, perhaps she has a more gentle and kind - hearted start compared to the original Harry. She might be more socially adept from the beginning, as her mother was popular. And she could use her resemblance to her mother to her advantage in certain situations, like getting on the good side of those who knew her mother well.
His relationship with Voldemort could change significantly. Voldemort might not immediately perceive Harry as a threat if he looks like a girl. He has a certain image of the boy who will be his downfall, and a girl - like Harry would disrupt that. This could give Harry an opportunity to get closer to Voldemort, perhaps infiltrate his ranks in a way that he couldn't as a boy.
Maybe when dealing with a younger student who is being bullied. Harry, like his mother, steps in immediately to stop the bullying. He consoles the younger student and offers advice on how to deal with such situations in the future.
Well, without reading the specific fanfiction, it could be that his mother's temper was kind - quick to protect and stand up for those she loved. Maybe she was fiery when it came to facing injustice, and Harry inheriting that means he might also be passionate about defending his friends and what he believes in.
Another possibility is that it just randomly appears one day. Magic in the Harry Potter world can be unpredictable. One morning, Harry wakes up and there it is at the foot of his bed. Or maybe a magical creature, like a house - elf that knew his mother, decides to bring the trunk to him. The house - elf could have been sworn to secrecy until the right moment when it senses that Harry is ready to discover his mother's secrets.
It could be offensive depending on how it's meant. If it's said with a dismissive or negative connotation towards the idea of black - influenced interpretations or fanfiction in general, then it's offensive. Fanfiction is a creative outlet, and black - centric interpretations can add new and valuable perspectives.
Well, if fem Harry looks like Lily, it might lead to all sorts of new plot developments. It could influence how she's treated by certain characters who knew Lily, or even give her some of Lily's personality traits.
