Don't just focus on the physical appearance change. Instead, explore how Harry's personality might shift or be influenced. For example, he might become more empathetic as he experiences some of the challenges that girls in the wizarding world face. Also, avoid the typical 'love triangle' where he's suddenly the object of every male character's affection just because he looks like a girl.
One way is to make the cause of his appearance change something unique. Not just a random spell, but maybe a result of a powerful magical artifact that he was trying to protect. Then, have the story revolve around his quest to reverse the effect while also learning important lessons about gender roles in the wizarding society. He could start a club or movement that challenges the traditional views on gender, which would be a fresh take on the concept.
Rather than the typical love - at - first - sight scenario, have their relationship develop gradually over time. For example, they start as comrades in arms, respecting each other's skills in battle. Then, as they share more experiences like hunting in the forest, they begin to notice little things about each other that they admire.
Avoid the typical 'sudden attraction because of puberty' trope. Instead, focus on how puberty affects their ninja training. For example, Sasuke might find that his body changing during puberty affects his chakra control, and Sakura, with her medical knowledge, tries to help him. This way, it's a fresh take on incorporating puberty into their story.
To avoid clichés in a Kingdom Hearts Yuri fanfic, first, focus on unique characterizations. Don't rely on the typical shy - girl and outgoing - girl trope. Dig deep into the personalities of the Kingdom Hearts characters you choose and explore their individual quirks. For example, if you choose Kairi, think about her experiences in the game and how that could shape her in a non - traditional way in a Yuri relationship. Second, create an original plot. Instead of the common 'they - fall - in - love - at - first - sight' scenario, build a story around shared goals or a common enemy within the Kingdom Hearts world. Maybe they have to work together to unlock a secret keyblade ability and their relationship develops from there.
One way is to make the punishment more like a learning experience. For instance, if Yuri made a mistake in a routine, Victor could have him study different skating techniques from other great skaters. This way, it's not really a punishment in a negative sense but more of an opportunity for Yuri to grow and improve.
Avoid the typical tropes like just making him a reincarnation of an Egyptian pharaoh right away. Instead, focus on the cultural aspects. For instance, show how his Egyptian family has certain traditions that are different from his Greek side. Maybe he has an Egyptian grandmother who tells him stories about the old gods in Arabic or Coptic, adding a unique cultural flavor.
It can be developed by focusing on Merlin's insecurities. For example, he might avoid certain situations like physical combat training because he's worried about being made fun of for his skinny frame. Then, through a series of events, he overcomes this fear. Maybe a new character comes to Camelot who also has a unique appearance and they bond over their differences.
One way is by changing her appearance and how others react to her. In the fanfiction, she could have long hair and a more feminine appearance. Characters might initially be surprised or treat her differently. For example, some might underestimate her at first because she's a girl, but she could prove them wrong.
It can be developed by focusing on how his daily life at Hogwarts changes. For instance, the staircases that move could be a huge obstacle. So the fanfiction could explore how he and his friends come up with solutions like using magic carpets or levitating charms. Also, his broom - flying might need to be reimagined. Maybe he gets a special broom that can be attached to his wheelchair and he can fly around in a different but still exciting way.
A simple way is to change Harry's perception of his parents. For instance, if he finds out that they were involved in some not - so - noble deeds in their past, it would give him a reason to ignore them. He could then start to look for role models elsewhere, like among the outcasts in Hogwarts.
One way is through his relationships. For example, if he's been let down by his friends, he might start to feel numb towards them. He could start to distance himself and not feel the same emotions he once did. Another way is through his experiences with the wizarding world's politics. If he feels constantly used or manipulated, it could lead to this numbness.
