In fanfic, Harry Potter may create his own world by exploring the boundaries of magic that were previously unknown. He might stumble upon ancient spells or magical artifacts that give him the power to shape a world. He could use his connection with his friends, like Hermione's intelligence and Ron's loyalty, to help him in this endeavor. For instance, they could research together in the restricted section of the library to find ways to create new magical laws and landscapes for his world.
Harry might first decide on the values of his world. Is it a world that values equality above all? Based on that, he'd then start to create institutions. He could build a magical council that enforces these values. He would also need to think about the inhabitants. Would he populate it with new species or just bring in his old friends? He could use his creativity to design unique magical creatures that are different from those in the original Potter world. And of course, he'd have to establish a system of magic that is distinct yet still related to what he already knows.
In fanfic, Naruto might create his own style by combining his unique jutsu. For example, he could blend his Rasengan with the Shadow Clone Jutsu in a new way. He may also draw inspiration from his friends and their techniques, like using Sakura's precision in his own combat style to make it more unpredictable.
In fanfic, Naruto may create his own jutsu based on his emotions. His strong will and never - give - up attitude can be translated into chakra - based techniques. For instance, when he's feeling extremely protective of someone, he channels that emotion into his chakra and creates a defensive jutsu. He also might draw inspiration from his memories. Remembering his training sessions with Jiraiya, he could take some of the basic techniques he learned and add his own twist to them, like adding a wind - element boost to a simple physical attack jutsu.
In fanfiction, Harry Potter might create his own magic through intense study of ancient and forgotten magical texts. He could discover long - lost incantations and then modify them to suit his needs. Also, his unique connection to Voldemort could play a role. By understanding the dark magic within Voldemort and combining it with the positive magic he's learned, he could create a new form of magic that balances both light and dark elements.
He would likely use Transfiguration magic. This would allow him to shape the raw materials into the form of a staff. He could also use Enchantment spells to give the staff special powers like the ability to repel dark magic or enhance his own spell - casting abilities.
One key element is his magic skills. His ability to perform complex spells and charms would be crucial in building his world. Another is his creativity. Harry has seen a lot in the wizarding world, and he can use that as inspiration to create something new. Also, his relationships play a part. The support of his friends and allies would be necessary for him to bring his vision of a new world to fruition.
Perhaps he barters with magical beings. He could offer his services in solving magical problems for them in exchange for rare building resources. For example, he might help a group of centaurs with a prophecy issue and in return, they give him enchanted wood or special stones. He may also get help from his friends who have access to different resources. Hermione might provide some rare books with building spells, and Ron could get some things from his family's old collection.
Technically, Harry Potter as a character can't create fanfiction. However, the 'Harry Potter' series has such a huge impact that it gives fans the motivation to create fanfiction. Fans might focus on different aspects. Some may explore the backstories of minor characters. For instance, they could write about how Neville Longbottom's parents were before they were attacked by Bellatrix Lestrange. They use the existing framework of the 'Harry Potter' world to build their own stories.
Maybe he first comes up with an interesting story idea. Then he sketches out the characters and scenes on paper. After that, he might add dialogues to bring the story to life.
Gwendy can fit in as a new friend to the main characters. She could join Harry, Ron and Hermione on their adventures and offer a fresh perspective. Maybe she has a different approach to solving problems, like using her knowledge of Muggle technology in a magical way.
