The appearance aspect is also a big part. How would Harry style his snake - hair? Would he try to hide it under a hat or let it be free? And how would the snakes interact with each other? Do they have different personalities like real snakes, and if so, how does Harry deal with that?
Well, it could be about a really strange and unique concept where Harry Potter is somehow transformed or related to snakes. Maybe it's a dark take on his character, with snake - like abilities or a connection to the snake - related magic in the Potterverse.
Perhaps his wings are related to his connection with his Patronus. Since his Patronus is a stag, the wings could be like an extension of that magical energy. They might give him the ability to soar high above Hogwarts and keep an eye on the school grounds, almost like a guardian angel. He could use this newfound ability to sense danger from afar and protect his friends more effectively.
In some of these fanfictions, the cat ears might be a result of a spell gone wrong. Maybe a mischievous student was trying to turn their pet cat into a human - like form but accidentally transferred some of the cat features to Harry instead. This would lead to a lot of chaos and hilarity as Harry tries to figure out how to reverse the spell while dealing with his new appearance.
A fanfiction might depict Harry Potter with curly hair as part of a 'what - if' scenario. What if Harry was born with curly hair instead of his normal straight hair? This simple change could have a domino effect on his character development. He might be more self - conscious about his appearance, which could in turn affect his relationships with Ron and Hermione. It could also change how the teachers and other students perceive him, potentially leading to different interactions and story arcs.
Another idea is that his curly hair is a side - effect of a powerful time - traveling spell. When he travels back in time, something about the magic of the past alters his appearance, giving him curly hair. In the fanfiction, this could be used to explore how small changes in the past can have big impacts on the present and future, all while Harry is dealing with his new look.
One possible fanfiction could be a story where Harry Potter's long black hair is a result of a magical spell gone wrong. Maybe he was trying to transform his appearance for a mission but instead ended up with long black hair that he has to figure out how to reverse while also dealing with the challenges of Hogwarts life.
There might be a fanfiction where Harry uses his ability to speak to snakes to communicate with a magical snake guardian of an ancient wizarding artifact. The snake could test Harry's worthiness to possess the artifact through a series of trials.
There might be a fanfiction where a magical snake is a guardian of an ancient Hogwarts secret. This snake could communicate with Harry in Parseltongue and guide him to discover something that has been long forgotten in the castle. It could be related to a powerful spell or a hidden chamber that holds the key to defeating a new dark force threatening the wizarding world.
One interesting concept could be exploring more about the Marauders' time at Hogwarts. Fanfiction might expand on their adventures, like pranks they played that were never mentioned in the original book. Another could be different interpretations of Sirius Black's escape and his relationship with Harry during that time.
Some fanfictions in Harry Potter 2 might play with the idea of the basilisk having different powers or weaknesses. It could also explore the idea of a hidden connection between Ginny and the Chamber of Secrets that goes beyond what was in the original story. There might be fanfictions that change the role of certain characters, like making Neville a more central figure in solving the mystery of the Chamber.
