The concept could work by having Harry bring the magic of the wizarding world into the Avengers' realm. His knowledge of potions could be used to create elixirs that give the Avengers new abilities. He could also use his wand to control the elements, like Thor does with his hammer, but in a more magical way. This would make him a valuable and almost god - like addition to the team.
Well, in this fanfiction idea, Harry Potter as a god in the Avengers world would mean he has a deep understanding of both magic and the forces at play in the Avengers universe. He could use his ability to communicate with magical creatures to enlist the help of some strange and powerful beasts in the fight against the villains. His Occlumency skills could also be used to protect the Avengers' minds from mind - controlling enemies. It would be a story full of crossovers and new ways of looking at both universes.
A crossover could function through a portal or some sort of magical event that links the two worlds. For instance, the Tesseract in the Avengers universe could malfunction and open a portal to the Harry Potter world. Then, the Avengers find themselves in a world full of magic and wizards. They soon learn about the God of Death and realize that they need to work with the wizards like Harry, Hermione, and Ron to stop this ultimate force. The Avengers' powers would be a new and strange thing in the Harry Potter world, and the wizards' magic would be equally fascinating to the Avengers.
Well, perhaps the lawyer character could be a Muggle - born in the Harry Potter world who is a huge Avengers fan. They somehow end up in a situation where they have to use their lawyering skills to represent the Avengers against some sort of magical - technological threat that combines elements from both universes. They might argue about who has the right to certain magical artifacts that are now in the hands of tech - savvy villains.
It could work if the Infinity Stones and the Deathly Hallows had some sort of connection. Since Harry is the Master of Death, he might be sensitive to the power of the Stones. The Avengers are dealing with the Stones' power, and Harry could bring his knowledge of dealing with powerful magical artifacts from his world. He could teach the Avengers about the consequences of misusing powerful items and how to safeguard against the corrupting influence of such power.
Well, first of all, the Avengers would need to locate Harry Potter. Maybe Hawkeye could use his eagle - eyed skills to spot him. Then, Captain America could lead the team in a rescue mission. Hulk could be the muscle, smashing through any obstacles in their way. Black Widow could use her combat skills to take out any enemies nearby. And finally, they could use the Quinjet to escape with Harry to safety.
Well, one way this could work is through some sort of magical time - travel or alternate universe scenario. Maybe in a world where magic and the Marvel universe collide, Bucky Barnes somehow ends up in the wizarding world and has a relationship with a witch, resulting in Harry Potter. It would be really interesting to see how Bucky's skills and experiences would influence Harry's upbringing and his adventures at Hogwarts.
Another way the 'Harry Potter is summoned' concept works is when a magical being with great power summons him. This could be a powerful wizard from another land or a magical creature like a phoenix or a centaur. They might summon Harry because they sense his unique magic or because they believe he has the ability to solve a problem that they can't. For example, a centaur might summon Harry to help deal with a dark magic that is corrupting the forest it guards.
Well, in the wizarding world of Harry Potter, magic is the norm. But if Harry were to use the Force, it could be like an extra power. Maybe it could enhance his already strong magical abilities. For example, when he's dueling, the Force could give him an edge in predicting his opponent's moves, just like it does in Star Wars for Jedi. It could also help him in sneaking around Hogwarts, like when he's using his Invisibility Cloak, the Force could make him even more undetectable.
The Death God in Harry Potter fanfiction could be a new, dark force. It may be introduced as an ancient entity that has been dormant for centuries and is now awakened. This entity could be in conflict with the existing magical order in Hogwarts and the wizarding world. It might target certain characters, like Harry, because of his connection to the prophecy and his power to defeat Voldemort. Fanfic writers may use this concept to explore themes of mortality, fate, and the limits of magic that were not fully explored in the original series.
Harry Potter might save the Avengers by using his magic to teleport them away from danger. He could use Apparition or the Floo Network if he could somehow make it work in the Avengers' world.
Harry Potter could lead the Avengers through his strategic thinking. He's had to plan against Voldemort and his Death Eaters. So he could come up with battle plans for the Avengers. He might use magic to communicate with the team over long distances, like a modified version of the Floo Network. Also, he would encourage the Avengers to embrace their individual strengths, just as he did with his classmates at Hogwarts.
