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.
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.
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.
One popular storyline might involve Spiderman having to balance his relationships with different Avengers while also dealing with his superhero duties. For example, he could be in a relationship with Black Widow, who helps him understand the darker side of the superhero world, and at the same time be friends - with - benefits with Scarlet Witch, who adds a magical and mysterious element to his life. Another could be where he forms a polyamorous relationship with some of the younger Avengers like Shuri and Kate Bishop, and they all work together to take on new threats in the Marvel universe.
One idea could be that a new character, perhaps a powerful sorcerer, arrives in the Avengers' world. This character has a unique power that attracts the Avengers in different ways, leading to a harem - like situation. For example, Thor might be intrigued by their strength in magic which he respects, while Black Widow could be interested in their stealthy and strategic use of power. Another plot could involve a time - travel accident where an Avenger from the future comes back and ends up in a complex relationship with the current Avengers team, forming a harem.
They could interact in a cultural exchange kind of way. Naruto could introduce the Avengers to the concept of ninja villages, the shinobi way of life, and the importance of honor in his world. The Avengers, on the other hand, could introduce Naruto to modern technology, different forms of government, and Western values. This interaction could lead to a deeper understanding between the two groups of characters and form the basis of a great fanfiction story.
Well, there's 'OC in the Avengers Harem'. It stands out because the author really delves deep into the character development of the OC. They give the OC a complex backstory that makes the harem aspect more believable. There are also some great action scenes in it that tie in with the romantic elements. The way the OC interacts with different Avengers members like Iron Man and Thor is really well - written.
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.
