One common theme is the clash of different worlds. Since it combines Harry Potter's magical world and the Avengers' superhero world, there's always the exploration of how these two very different settings interact. For example, how magic affects high - tech gadgets or how superpowers compare to spells.
Peter Parker (Spider - Man) could also be a great main character for this kind of fanfiction. His youthful charm and heroic nature would appeal to characters in both universes. He could be on a school exchange program in Hogwarts (using some multiverse - like excuse) and during his stay, he gets involved with helping the wizards while also catching the eyes of Ginny Weasley, MJ, and Black Widow, creating an interesting harem situation.
There's also 'Harry in the Avengers' Harem'. In this fanfiction, Harry is thrown into the world of the Avengers and forms relationships with multiple characters, creating a harem dynamic. The story often has him using his magical skills to help the Avengers in new and unexpected ways. It's quite engaging as it explores how different magical and super - powered abilities interact.
Maybe the Infinity Stones are scattered across the Harry Potter universe. The Avengers have to team up with Harry Potter and his friends to retrieve them. During this adventure, a love triangle or rather a harem - like situation develops. For example, Harry Potter could find himself in the middle of a relationship with Pepper Potts and Ginny Weasley. They would all need to work together to stop a new dark force that is attracted to the power of the Stones.
One common theme is the outsider - within concept. The OC is usually an outsider who then becomes part of the Avengers' world, and the harem forms around that dynamic. Another theme is the exploration of different powers and how they interact. For example, if the OC has a unique power, how does it mesh with the powers of the Avengers in the context of the relationships.
A new superhero created specifically for the fanfiction could be the main character. This character could have a power that is a combination of different Avenger's powers, like being able to have super strength like Hulk and also fly like Iron Man. Their unique abilities would draw the attention of the Avengers, making them the center of a harem - like story.
Well, it could be a really interesting concept. Maybe Harry could use his magic skills in the Avengers universe. He could help with things like cloaking the Avengers' base with magic or using spells to disarm enemies in a unique way that the Avengers have never seen before. His knowledge of the magical world might also introduce new elements to the Avengers' understanding of different dimensions and powers.
In fanfiction, Raven could be an interesting addition to the Harry Potter and Avengers universes. Maybe she has some sort of magic ability that links her to the wizarding world of Harry Potter and at the same time, she might possess powers that could make her fit into the Avengers' world. For example, she could be a powerful witch who also has enhanced physical abilities like the superheroes in the Avengers. She might interact with Harry Potter characters by using her unique powers to solve some magical problems at Hogwarts. And in the Avengers' side, she could be a new recruit with her own set of skills and backstory.
A petal could potentially be a character's name or nickname in a fanfic that combines Harry Potter and Avengers. It could be a magical petal that has the ability to transport characters between the two universes. For instance, if a character from the Avengers picks up this petal, they might suddenly find themselves in Hogwarts. Or perhaps it's a petal from a dark magical plant that is being used for evil purposes by a villain who has knowledge of both magical worlds.
One possible scenario in this fanfiction could be that the wizards from Harry Potter and the superheroes from Avengers find themselves on a common battleground. Maybe they initially misunderstand each other due to their different powers and ways of fighting. For example, the Avengers might be a bit skeptical about magic at first. However, as the battle progresses, they realize that they can combine their forces. The wizards can use spells to create barriers or illusions, while the Avengers use their physical strength and high - tech gadgets to take on the more brute - force enemies. Eventually, they form an alliance and defeat the common foe, which could be a powerful dark wizard who has also got his hands on some sort of dangerous alien technology.
