Well, another great one could be where Harry teams up with Tony Stark specifically. Harry's magical insights and Stark's technological genius combine in unexpected ways. They might work together to create new defenses or offensive strategies against threats that neither could handle alone. This kind of fanfiction often plays with the idea of magic and technology co - existing and complementing each other.
A common plot point is the initial meeting. Usually, Harry has to somehow get to the Avengers' universe or vice versa. This can be through a magical portal or some sort of interdimensional accident.
A popular plotline is Peter bringing a fresh perspective to the Avengers. Because he's a young hero and has a different view of the world compared to the more established Avengers, he can offer new ways of thinking. This could be in how to deal with a villain, or how to approach a problem in a more ethical way. For instance, he might suggest trying to rehabilitate a villain instead of just fighting them, which the Avengers might not have considered before.
Often, there's a plotline where Loki has some inside knowledge about an enemy that the Avengers are facing. Maybe he has some past connection with the villain. So, he becomes a key source of information. There could also be a plot where Loki's presence in the Avengers causes some internal conflict within the team. Some members don't trust him, while others see his potential. This conflict and how it's resolved is a common plotline too. And sometimes, Loki might get kidnapped or held hostage by the enemy because of his new - found alliance with the Avengers, and the team has to rescue him.
One possible plot could be that Spider - Man uses his agility and spider - sense to detect an enemy that the Avengers have overlooked. For example, he might notice some hidden Chitauri technology that is about to activate and cause chaos. So he swings in, warns the Avengers, and then together they figure out how to disable it.
Spider - Man's web - slinging ability can be really useful for the Avengers. He could create webs to trap enemies, which would be a great addition to the Avengers' combat tactics. For example, when fighting against a group of fast - moving enemies like Ultron's drones, his webs can slow them down, giving the other Avengers like Captain America or Black Widow an easier time to take them out.
A really interesting one is 'Spider - Man's Avengers Assist'. In this fanfic, Peter is called upon to help the Avengers during a city - wide crisis. He swings into action, using his web - slinging skills to rescue civilians and also providing crucial intelligence to the Avengers about the enemy's movements. His street - level experience gives the Avengers an edge they didn't have before.
A really interesting one is 'Dobby's Grand Adventures with Harry'. Here, Dobby and Harry go on unexpected adventures outside of Hogwarts. Dobby's knowledge of the wizarding world's hidden places comes in handy. They discover ancient magic artifacts together and Dobby's quick thinking often saves Harry from danger. It's a fun and exciting read that shows their friendship growing stronger.
