It could be due to misinformation or a lack of in - depth knowledge. People might see some action scenes in Harry Potter, like the duels between wizards, and wrongly associate it with ninja - like combat. But in reality, the magic in Harry Potter is very different from the skills of ninjas. Wizards use wands and spells, while ninjas rely on their physical skills and stealth techniques. Also, the settings and cultures are completely different. Harry Potter is set in a Western - inspired magical world, while ninja stories are often based in an Asian context.
Perhaps some people who are into both Harry Potter and ninja - related stuff try to blend the two in their minds in a very strange way. They might think that since both involve some form of combat and a certain level of secrecy (wizards have their own hidden world, and ninjas are known for their stealth), they could consider Harry Potter as a ninja fanfiction. But this is a huge misunderstanding as the two are fundamentally different in terms of story, characters, and the overall universe they are set in.
Perhaps some people misunderstand the concept. They might see elements in 'Harry Potter' that seem familiar from other fantasy works and wrongly assume it's fanfiction. But in fact, J.K. Rowling just drew on some common fantasy tropes and made them her own in a very original way.
First, you need to have a solid understanding of both universes. Know the rules of magic in Harry Potter and the combat styles and lore in Ninja Gaiden. Then, create an engaging plot. It could be a simple quest or a complex battle against a combined evil. Next, develop your characters well. Show how the Harry Potter characters react to the Ninja Gaiden world and vice versa. For example, how would Hermione approach learning ninja skills? Finally, write in a way that keeps the readers interested, with good pacing and description.
Another theme is the exploration of trust. When Harry is wrongly accused, he discovers who his true friends are. Some friends may abandon him while others will stand by him no matter what. This is seen in various fanfictions where characters like Hermione and Ron's loyalty is put to the test.
It could be a character whose fate was changed in the fanfiction compared to the original book. Maybe it's a minor character who was supposed to die but didn't.
It's wrong because Harry Potter has a completely different origin and concept. It's J.K. Rowling's creation about a magical world, not related to Sprite at all.
One way could be to have the Cartoons Ninja be a magical being from a different dimension that has the ability to cross into the Harry Potter universe. Dudley could encounter this ninja first, thinking it's just some new strange thing in his muggle world. But then it turns out the ninja has a connection to Harry's world. Maybe the ninja is on a mission to find a powerful magical item that Harry also needs, and Dudley gets caught in the middle.
It's a wild concept. Naruto is from a world where physical combat and chakra control are key, while Harry Potter's world is centered around magic. If summoned, Naruto could be seen as an otherworldly being. His presence could create chaos as the wizarding world tries to figure out how to deal with him. He might start challenging the dark wizards using his own brand of justice.
Some people might be confused because of the huge amount of fan - created content related to Harry Potter. There are so many fanfictions, fan art, and fan - made movies that they might assume the original work is also fanfiction. But in reality, it's the original that inspired all this fan - made stuff.
One great 'Ninja Harry Potter' fanfiction is 'Harry Potter: The Ninja's Path'. It combines the magic of the Harry Potter world with ninja skills in an exciting way. The story follows Harry as he discovers a hidden ninja heritage and uses these new skills to face Voldemort.
The combination of two very different concepts. Harry Potter is all about magic in a European - inspired wizarding world, while ninjas are from a completely different Asian martial arts and stealth - based culture. When combined, it creates a whole new and exciting dynamic. For instance, seeing Harry use a magic - infused ninja sword is really cool.
