There are also fanfictions where Harry's Hogwarts friends join him in the Avengers' world. Hermione could use her vast knowledge to help Iron Man with his tech, and Ron could provide some comical relief during intense Avengers missions. It's a fun blend of two very different universes.
There's a 'Harry meets other Potters' fanfic where they meet in a time - traveling scenario. Harry from different points in time comes together. It's really cool as they compare their different experiences at Hogwarts, like how magic was taught differently in their respective times, and they also exchange spells and magical knowledge.
A great 'Merlin meets Harry Potter' fanfiction could involve the two of them teaming up to solve a mystery that spans both their worlds. It could be that a dark wizard has found a way to use the magic from Merlin's time to create a new and dangerous threat. Merlin and Harry would have to combine their knowledge and skills, with Merlin's deep understanding of magic's roots and Harry's experience with modern magical threats.
In some fanfictions, fem Harry Potter could end up training with the Avengers. Maybe Black Widow takes her under her wing to teach her combat skills, while Thor tries to understand the nature of her magic. This could lead to a lot of character development for fem Harry Potter as she learns new ways of fighting and the Avengers learn more about the magic that exists in her world. It would be a great blend of two very different universes.
A really cool fanfiction idea is that James Potter meets Harry Potter in an alternate universe. In this universe, James never died and he gets to see Harry as a normal, happy kid without the burden of being 'The Boy Who Lived'. They might go on adventures together in Hogwarts that are more about exploration and fun rather than fighting dark forces. Another interesting one could be where James Potter appears as a ghost to Harry Potter. He gives Harry advice on how to deal with his love life, something that James was quite good at during his own Hogwarts days.
Well, in the world of 'Avengers watch Avengers Assemble' fanfictions, you can find some really creative works. For instance, there could be a fanfiction where the Avengers are forced to watch their own show as a form of training. They have to learn from their past mistakes shown in the episodes. Some fanfictions might also include new characters that are created specifically for this 'watching' scenario. These new characters could interact with the Avengers in unique ways, like a young fan who gets magically transported into the viewing room with the Avengers and asks them all sorts of questions about their adventures.
One interesting 'Avengers discipline' fanfiction could be about Captain America having to discipline a new and reckless recruit. He might use his old - fashioned values and military - like training methods to instill a sense of responsibility.
One interesting 'Avengers Friday' fanfiction could be about Friday, Stark's AI, having her own adventure with the Avengers. Maybe she gets a physical form for a day and has to learn how to interact in the real world with the team. She could end up saving the day in a unique way that only she, with her vast knowledge and different perspective, could do.
There's also 'A New Perspective' which takes a different approach. It shows Harry and Ginny's meetings through the eyes of other characters at first. This gives a unique view on how their relationship is perceived by those around them and then dives into their own interactions more deeply.
One possible plotline could be Yelena initially being distrustful of the Avengers. Maybe she has been taught to view them as enemies, but as she gets to know them, she realizes they have similar goals. For example, she might find common ground with Natasha's former teammates in their fight against evil.
One interesting Bucky Barnes Avengers fanfiction could be 'The Reformed Winter Soldier'. In it, Bucky struggles to fully integrate into the Avengers while dealing with his past traumas. It shows his journey of redemption within the Avengers family.
