One way is to start with his introduction into the wizarding world. Maybe he was on a job in the Muggle world near a magical place and accidentally got dragged into the magical realm. Then, he discovers his own latent magical abilities or he could be completely Muggle - born but very good at adapting to the new environment using his hitman skills.
A great way to develop it would be to create conflicts. For example, he could be targeted by the Death Eaters because they see him as a threat, or he could be hired by the Order of the Phoenix to take out some key Death Eater operatives. His relationships with the main Harry Potter characters could also be explored. Does he befriend Harry? Or does he have a more antagonistic relationship with Hermione because she doesn't trust his methods? And all of this can be set against the backdrop of the magical world's politics and power struggles.
To develop this fanfiction, we could also focus on his character growth. As a hitman, he might start with a very self - centered and survival - oriented mindset. But as he experiences the love, friendship, and the fight for justice in the Harry Potter world, he could change. He could start to care about more than just his own well - being and his next job. His hitman skills could be used to train the younger students in self - defense in a more unorthodox way. And his past could be gradually revealed through his interactions with other characters, adding depth and mystery to the story.
Well, if we think about it, this kind of fanfiction could be really unique. It could explore how Nana's older brother's skills as a hitman would translate into the magical world of Harry Potter. For example, he might use non - magical weapons in a creative way against magical foes, or he could form alliances with some of the more morally ambiguous characters in the series who might be interested in his services.
Her magical abilities can play a big role in her development. If she has a special gift, like being able to communicate with magical creatures in a way no one else can, it can shape her character. She could be seen as an outcast by some in the wizarding world because of this strange ability, but she uses it to her advantage. For instance, she might get help from a powerful magical creature to save Harry from a dangerous situation.
To develop her character, start with her appearance. She could have the same green eyes as Harry but with long, flowing red hair like their mother. Then, think about her personality. She might be more headstrong and confident than Harry, having grown up a bit earlier. For instance, she could be the type to stand up to bullies without hesitation, even when they are older and more powerful wizards.
One possible plotline could be that the older brother is a prodigy at magic and overshadows Harry in the beginning. For example, he might be the top of his class in every subject at Hogwarts. This could create some jealousy or a sense of inadequacy in Harry at first. But as the story progresses, they could learn to support each other and the older brother could use his skills to help Harry in his battles against Voldemort.
In fanfiction, the idea of Harry being Naruto's older brother might be possible if we consider that both characters have some similarities in their personalities. They are both determined and face great challenges. So, a writer could create a backstory where there is some sort of connection between their two worlds that makes them family. For example, perhaps a wizard from the Harry Potter world visited the Naruto world long ago and had a relationship that led to Harry and Naruto being related.
In this fanfiction, the older brother of the Boy - Who - Lived (BWL) might have a very different relationship with the wizarding world. He could be an outcast because he is overshadowed by his younger brother's fame. So, he might decide to create his own path, away from the typical Hogwarts hero - worship. But when danger really comes to Harry, he steps up. He might have some knowledge about the dark arts that he uses to fight the enemies in a more unorthodox way compared to Dumbledore's side.
One interesting fanfiction could be 'The Slytherin Legacy'. In this, Harry Potter's older Slytherin brother has to navigate the complex world of Hogwarts. He struggles with the family's expectations and the Slytherin house's reputation. Another one is 'Brother in the Shadows'. It shows how he tries to protect Harry from afar while dealing with his own dark desires that come with being a Slytherin.
Well, he could be developed as a more introverted character compared to Ash. Instead of being as outgoing and eager to make friends, he might be more focused on his research of Pokemon, like studying their behaviors or habitats. This would make him a unique character with his own set of goals and values.
To develop it, you could introduce a new character who is a hybrid of a wizard and a Cybertronian. This character could be the link between the two worlds. Harry could then be drawn into the Cybertronian world through this character. In the Cybertronian world, Harry could discover that magic has a different manifestation. He could learn to combine his magic with the technology of the Cybertronians. For example, he could use his wand to control the energy flow in a Cybertronian's body, or use a spell to enhance a Cybertronian's weapon. The story could also explore the ethical implications of mixing magic and technology, and how it affects both the wizarding world and the Cybertronian society.
If Harry wears armor, it could make him seem more like a knight. His sense of chivalry could be enhanced. He might be more confident in battles, which could lead to him taking more risks. This would show his growth as a character, as he becomes bolder in the face of danger.
