Their friendship could make the Tri - Wizard Tournament less cutthroat between them. Instead of seeing each other as just competitors, they might help each other out in the tasks. For example, if one of them discovers a useful spell or strategy, they could share it with the other. This would be a big change from the traditional view of the tournament where everyone is out for themselves.
It deepens their bond. Harry starts to trust Cedric more, seeing him as a reliable friend. This protectiveness makes Harry feel safe around Cedric.
If they were friends before Hogwarts, it could create a lot of internal conflict at Hogwarts. Draco might be torn between his new Slytherin friends who dislike Harry and his long - standing friendship with Harry. He might try to keep their friendship a secret, which could lead to misunderstandings between them.
Their friendship could change the perception of dark magic. Tom, having been on the path to becoming Voldemort, might have a different view on dark magic with Harry as his friend. They could work on redefining what is considered dark magic and find ways to use some of those spells in a more positive or controlled way. This could revolutionize the study of magic at Hogwarts and in the wizarding world in general.
Well, in some fanfictions, Cedric might use his magical skills to shield Harry from physical attacks. For example, he could cast protective spells like Protego Maxima to create a strong shield around Harry when they are in danger. Maybe in a situation where dark wizards are attacking, Cedric steps in front of Harry and uses his wand to fend off the spells aimed at Harry.
One great 'Harry and Cedric friends' fanfiction could be 'The Bond Beyond Houses'. It delves into how their friendship might have developed further if Cedric hadn't met his untimely death. It shows them sharing secrets about their respective families and helping each other with their studies at Hogwarts.
One interesting plotline could be Harry and Cedric teaming up to solve a mystery within Hogwarts that the teachers are oblivious to. They use their combined skills, Harry's courage and Cedric's intelligence, to figure out what's really going on. For example, they might discover a hidden chamber that has been long forgotten and holds a powerful magical artifact. Another could be that they form a study group which then turns into a deep friendship. They help each other with their studies, especially in difficult subjects like Potions and Transfiguration. And finally, they could be united in trying to improve the relations between the different houses in Hogwarts. By being friends, they show that Gryffindors and Hufflepuffs can work together and be allies, rather than just competitors in the Tri - Wizard Tournament.
Their friendship could also lead to a different perspective on the Uchiha clan's situation. Itachi's actions were complex and his friendship with Naruto could have made Naruto more involved in the Uchiha clan's affairs. This might have led to a different solution to the conflict between the Uchiha clan and Konoha, preventing the massacre. In turn, this would have a huge impact on the political situation in the ninja world.
If Naruto and Madara become friends, it could completely change the power balance. Their combined strength would be a deterrent to any potential invaders. On a more positive note, it could inspire a new generation of ninjas to look beyond past grudges. The younger ninjas would see that even the most bitter enemies can become friends. This could lead to a more unified ninja world where different clans and villages work together more closely. For example, the Uchiha clan might regain more trust within the Leaf village, and other villages might be more open to sharing resources and knowledge.
It could strengthen their relationship. If Cedric shows genuine concern, Harry will likely feel closer to him.
It can strain their friendship. An argument might make them avoid each other for a while, creating a sense of distance. But if they truly value their friendship, they'll eventually come back together and resolve their differences, making their bond even stronger in the end.
