One interesting plot could be that an ancient evil from the Fate Stay world threatens the Harry Potter universe. Mordred teams up with Harry Potter and his friends. Mordred brings her combat skills and knowledge of her world's magic, while Harry and his friends contribute their own wizarding skills. They have to learn to trust each other despite their differences in origin and values, and this journey of cooperation can be full of character development and exciting battles.
A plot where Mordred attends Hogwarts undercover could be very interesting. She could be on a secret mission while trying to fit in with the students and learn about the wizarding magic, which is very different from her own powers.
Yes, there are quite a few out there. Some focus on unique crossovers where the magic of Harry Potter's world combines with the lore of Fate Stay. For example, you might find ones where Mordred ends up at Hogwarts and has to adapt to the new magical environment. It's really interesting to see how different the two universes are and how the characters interact.
Well, it could be about her trying to redeem the name of her father. Maybe she joins the Holy Grail War not for power but to prove that Mordred's line can be heroic. She might form alliances with some of the traditional heroes, like Saber, and they initially have a lot of mistrust but over time come to respect each other.
A great plot could involve the magic systems of both universes colliding. For instance, the spells in Harry Potter and the magecraft in Fate Stay Night. The Grail in Fate Stay Night could be related to a powerful and dark magical artifact in the Harry Potter world. Characters like Shirou could meet Hermione, and they could compare their knowledge of magic. Shirou might learn some new spells from Hermione, while Hermione could be intrigued by Shirou's ability to reinforce objects. This could lead to a joint effort to stop a common threat that is using the combined power of both magic systems for evil.
One interesting crossover could be the magic systems interacting. In 'Harry Potter', magic is more about spells and potions, while in 'Fate Stay Night', it's linked to Servants and their powers. Maybe a scenario where a Harry Potter character tries to summon a Servant. Another could be the characters' moral compasses clashing or aligning. For example, how would Harry Potter deal with the often morally gray situations in the 'Fate Stay Night' universe? And of course, there could be crossovers in the settings, like Hogwarts being a battleground for a Holy Grail War.
A plot could be that Mordred is summoned by a powerful ninja as a last - ditch effort to fight against an ancient evil that has emerged in the Naruto world. This evil has powers similar to some of the powerful Servants in Fate Stay Night, so Mordred's expertise is needed.
Well, in 'Harry Potter Heir of Mordred' fanfiction, it could be that the author creates a whole new backstory for Harry. Maybe Mordred had some hidden magic or prophecy that is now linked to Harry. It could involve battles, new magical abilities for Harry, and interactions with characters in a way that's different from the original series. For example, he might have to face enemies that are also related to Mordred's past, and this could lead to a series of adventures and challenges.
Perhaps a plot where the Holy Grail War from Fate Stay Night gets disrupted by the arrival of some key players from Fate Apocrypha. This could lead to new alliances and rivalries. Like Shirou from Fate Stay Night having to team up with a character from Fate Apocrypha, say Sieg, to face a common enemy that is after the power of the Grail in both their worlds.
One interesting crossover could be the magic systems interacting. In 'Harry Potter', magic is more about spells and potions, while in 'Fate Stay Night' it's more based on Servants and their abilities. A crossover might show how a Hogwarts student could summon a Servant, perhaps using a modified summoning charm.
One interesting crossover could be the characters from Fate Stay Night finding themselves in the wizarding world of Harry Potter. For example, Saber could be mistaken for a powerful magical being. Maybe she'd be intrigued by the use of wands instead of her own magic swords. Another idea is that the mages in Fate Stay Night could learn new spells from the Hogwarts professors. It would be a clash of two very different magical systems that could lead to some really cool and unexpected storylines.
One interesting crossover could be the characters from Fate Stay Night attending Hogwarts. For example, Saber could be a transfer student, learning magic in a world she's not used to. Her combat skills might be combined with magic in unique ways, like using her swordsmanship along with transfiguration spells.
