It could also be about a new character in a fan - created story within the Potter world. This character might possess a power related to cold fury, like being able to freeze things when enraged. And the fanfiction could explore how this power affects the character's relationships with others in Hogwarts or the wizarding world at large.
Another possibility is that it's a story where the concept of cold fury is used as a metaphor. For example, the cold fury could represent the long - held grudges and slow - burning resentments among the different houses in Hogwarts. The fanfiction might then show how these emotions play out in various scenarios, like during Quidditch matches or in the face of external threats to the school.
Since it's a fanfiction, it could have the main characters from the original series like Harry, Hermione, and Ron. They might be dealing with situations that involve cold fury in ways that J.K. Rowling didn't explore 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.
One possible plot could be that Harry discovers a hidden Night Fury in the Forbidden Forest. He realizes that the dragon has some sort of connection to an ancient magic in the wizarding world. So, he tries to protect it from those who would want to use it for dark purposes. Along the way, he learns new spells and techniques from the Night Fury, which he then uses to fight against Voldemort's forces.
One idea could be that a Night Fury somehow gets transported into the Harry Potter universe. Maybe it crashes into the Forbidden Forest and Harry and his friends discover it. They could try to figure out how to communicate with it and use its abilities to their advantage against the dark forces in Hogwarts.
It could be due to a spell. There are many dark spells in the wizarding world that might cause a person to feel cold. For example, some curses can drain the warmth from a body. If Harry was targeted by such a spell, he would be cold. Also, it might be related to his emotional state. If he was feeling lonely or scared, it could make him feel cold inside, just like when people are in a bad mood in real life, they might feel colder than usual.
One possible plot could be that Nick Fury somehow discovers the wizarding world. Maybe he's investigating strange energy readings that lead him to Hogwarts. Harry Potter becomes his friend as they team up to stop a new threat that involves both the magical and non - magical worlds. For example, a group of dark wizards are trying to use Muggle technology to enhance their dark magic, and Fury's knowledge of technology combined with Harry's magic can stop them.
It would be a wild mix. Maybe Harry would inherit some of Thor's powers like super strength or the ability to control lightning, on top of his wizarding abilities. His magical world and the world of Thor might collide, with him having to deal with both Hogwarts and the Asgardian politics perhaps.
A possible scenario is that Harry Potter, not fully understanding the importance of secrecy in Fury's world, reveals some magic in public while Fury is trying to keep a low profile. This would not only annoy Fury but also put his operations at risk. Also, Harry might try to 'fix' things using magic when Fury has his own high - tech solutions in place. For instance, if there's a malfunction in a S.H.I.E.L.D. device, Harry might try to repair it with a spell, which would be seen as interfering by Fury.
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.
