Well, it could be a really fun and out - of - the - ordinary story. Harry might use his new magical girl look to his advantage in battles. He could have a more flamboyant style of magic with a magical girl wand that shoots sparkles and has special powers. His friends would be both shocked and amused at his new appearance.
In this fanfiction, Harry as a magical girl would bring a whole new dynamic to the wizarding world. His enemies might underestimate him at first because of his girly appearance. However, he would surprise them with his strength and cunning. He could also make new friends among the magical creatures who are more attuned to the magical girl aesthetic. His journey would be about not only fighting the dark forces but also coming to terms with this new identity and showing that being a magical girl doesn't make him any less of a powerful wizard.
The story could start with Harry stumbling upon a strange magical artifact that, when touched, transforms him into a magical girl. At first, he's embarrassed, but then he realizes he can still fight Voldemort in this new form. He might even gain new magical abilities like the power to heal with a touch or fly without a broom. His Hogwarts uniform would be replaced with a frilly magical girl dress, and he'd have to learn to move around in it while still being a hero.
It could be a really fun and unique story. Maybe Harry would bring his own brand of wizardry to the magic girl look. He might use his spells in unexpected ways while wearing the frilly and colorful magic girl outfit. For example, he could use the levitation spell to make his magic girl accessories float around him in a really cool display. And his friends would probably have some very interesting reactions to his new look.
Hermione would probably be initially shocked but then would be very curious about the magical properties that might have caused the transformation. Ron, on the other hand, would likely tease Harry at first but would soon come to accept it and see it as just another strange thing in the wizarding world.
Well, such a fanfiction would likely rewrite a lot of the original plot. Harry as a girl might face different challenges at Hogwarts. There could be more focus on her dealing with the typical girl - related issues in a magical world, like how she dresses for the Yule Ball in a different way than the original Harry. Her relationship with Draco could also be different. Instead of just being rivals, there could be a more complex, perhaps romantic, undertone to their interactions as she, as a girl, might be seen as more of a threat or an object of interest to Draco in a different sense.
A possible plot could be that Harry is entered into a magical competition where the rules state he has to compete as a girl. So he dons a girl's disguise and has to deal with the challenges not only of the competition but also of maintaining his new identity. His friends might have a hard time adjusting too, and there could be some comical misunderstandings along the way.
He might be doing it for a prank. Just for laughs and to surprise people around him.
They could also have a connection to his emotions. In fanfiction, perhaps when Harry is feeling angry, the tattoos might darken or become more prominent. When he is happy, they could shine brightly. This connection between his emotions and the tattoos could be a way for him to better understand himself and also for others around him to gauge his mood without him having to say a word. And the tattoos could potentially attract certain magical energies based on his emotional state, further affecting his magic.
Well, Hermione would likely approach it with her usual intellectual curiosity. She might study the cultural significance of the magic girl look in the wizarding world. Ron would probably make some teasing remarks initially, but deep down he'd still be loyal to Harry. And Ginny would probably find it really cool and might even want to join in on the fun, suggesting some improvements to Harry's magic girl look.
Imagine Harry Potter being raised by Dyson. First of all, his living environment would be completely different. Instead of Hogwarts and the wizarding world, he'd be in a world full of Fae, werewolves, and other supernatural beings. Dyson's mentoring would make Harry more street - smart and perhaps more in tune with his instincts. His magical education might be a blend of wizarding magic and Fae magic. He could also have a different attitude towards non - magical beings, as the Fae world has its own views on mortals. This would create a Harry Potter who is a unique blend of both universes' characteristics.
Well, in such a fanfic, Harry Potter might find himself in a world where ship girls exist. He could use his knowledge of magic to protect the ship girls from threats. For example, he could cast protective spells around their ships. Also, he might learn about the unique cultures and technologies related to the ship girls, and perhaps even introduce some of his wizarding world elements to them, like using magic to repair their ships faster.
One popular one might be where Harry has to go undercover as a girl for a mission in Hogwarts. He might struggle with the new identity at first, like getting used to wearing skirts and acting more 'girly'. This could lead to some really funny and endearing moments, especially when his friends like Ron and Hermione react to his new look.
