At the beginning, their interaction could be full of misunderstandings. Harry might not understand Fury's no - nonsense attitude towards threats, and Fury could be put off by Harry's use of magic which he can't immediately explain. However, as they learn more about each other's worlds, they could start to work together. Harry could use his magic to help Fury in situations where normal technology fails, and Fury could offer his strategic thinking and resources to Harry in dealing with magical threats that have implications in the Muggle world.
Percy would probably be a bit wary at first. He's used to the demigod world and Fury's whole S.H.I.E.L.D. thing would seem really different. But Fury would be all business. He'd likely be sizing Percy up, trying to figure out how to best use his powers.
The friendship could start from mutual respect. Harry would respect Fury's leadership and combat skills, while Fury would admire Harry's magical abilities and his courage. For instance, when they first meet during a crisis situation, they both see how the other is handling the danger. Harry is using his magic to fend off dark creatures, and Fury is using his high - tech gadgets. After the initial encounter, they start to communicate more, sharing their different worldviews.
Percy and Nick Fury would likely have a very interesting dynamic. Percy is used to a more straightforward world of good vs. evil in terms of the demigod battles. Fury, on the other hand, is all about the political and strategic side of things. Percy might be a bit impulsive at times, which could annoy Fury, but Fury would also recognize Percy's power. Percy would probably be in awe of Fury's knowledge and resources at first.
If Harry Potter were raised by Nick Fury, it would be a very different story. First of all, Harry's upbringing would be much more militaristic. Fury would instill in him a sense of discipline and a no - nonsense attitude. Harry would likely be more secretive about his magic, perhaps only using it when necessary for a mission. He might also have a team of magical and non - magical allies, similar to the Avengers, to help him fight against Voldemort and his Death Eaters. His Hogwarts experience would be unique too. He might not be as trusting of the school's authorities as he was in the original story, and would instead rely more on his own instincts and training from Fury.
One possible plot could be that Harry Potter, as the son of Nick Fury, grows up in the wizarding world but with an added sense of secrecy and strategic thinking inherited from Fury. He might use his father's espionage skills to uncover dark secrets in Hogwarts, like a new Death Eater plot. He could also have a unique way of using magic, combining it with the combat and intelligence - gathering tactics he learned from Fury.
Well, it could be really chaotic. Harry might use his magic in ways that Nick Fury, being used to more 'normal' superhero stuff, would find extremely irritating. For example, Harry could accidentally make Fury's important documents fly around with a spell. Or Harry might constantly talk about the wizarding world in a way that Fury just can't understand and it annoys him because he's trying to focus on his own S.H.I.E.L.D. business.
In a fanfiction scenario, perhaps Nick Fury is on a mission to recruit magical beings for S.H.I.E.L.D. He discovers the existence of the Harry Potter world and tries to make contact. Harry and his friends could be initially suspicious but then see the potential in working with Fury. They could exchange knowledge, with the wizards learning about Muggle technology and Fury learning about magic. This could lead to some really interesting team - ups and adventures against common enemies.
If Harry Potter was raised by Nick Fury, his personality would transform significantly. He would be more self - confident in a different way. Instead of relying on the love and support of his friends as much, he would trust in his own abilities and training. Harry would be more of a lone wolf, not shying away from working alone if it meant getting the job done. His sense of humor would likely be drier, more like Fury's sardonic remarks. He would also have a greater sense of urgency and purpose. In the wizarding world, he might not be as patient with the slow - moving bureaucracy of Hogwarts or the Ministry of Magic. He would be more action - oriented, ready to jump into a situation and fix it rather than waiting for others to make a move.
He'd be more of a badass. Harry would probably be more confident and assertive, taking charge like Fury. He might not be as hesitant in the face of danger as in the original books.
If Nick Fury visited Hogwarts, he would surely be intrigued by the castle's defenses. He might compare them to S.H.I.E.L.D.'s security measures. The magic that protects Hogwarts, like the anti - Apparition jinx and the moving staircases, would be both fascinating and a bit of a headache for him as he tries to navigate the place.
