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.
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.
In a fanfiction where the Avengers save Harry Potter, it would be a total game - changer. The Avengers' unique skills would be very useful. Hulk could smash through any dark magic barriers. Black Widow and Hawkeye could use their stealth and marksmanship to take out threats from the shadows. And with their combined strength, they might be able to protect Harry Potter from any danger, including Voldemort's Killing Curse.
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.
He could use his invisibility cloak for stealth missions with the Avengers.
Well, Harry Potter might assist the Avengers in fanfiction by providing unique forms of transportation. His ability to apparate or use the Floo Network could be a great advantage for the Avengers. Also, his experience in fighting dark magic could give the Avengers new strategies against their powerful foes.
In fanfiction, Bruce Banner could save Harry Potter through his scientific knowledge as well as the Hulk's powers. Maybe there's a situation where a magical curse is spreading uncontrollably. Bruce, in his normal state, could analyze the curse using his scientific expertise and figure out a way to stop it. And if there are any physical manifestations of the curse that need to be dealt with, the Hulk could step in and use his strength to destroy or contain them. This would show a great combination of the scientific and magical elements in the story.
In fanfiction, Harry Potter might save Lyanna Stark by using his magic skills. For example, he could use a powerful spell to protect her from some imminent danger like an attack from the White Walkers. His ability to apparate could also be crucial, allowing him to quickly reach her when she's in trouble and whisk her away to safety.
The concept of Animagus in an Avengers fanfiction could also be used for character development. Suppose an Avenger discovers they have the potential to be an Animagus. This would open up a whole new side of their personality. They would have to learn about magic, which is very different from their usual super - power knowledge. This could lead to interesting interactions with other characters, like Thor, who might be intrigued by this new form of power.
Perhaps there is a prophecy in both universes that foretells of a great danger that only the combined forces of Harry Potter and the Avengers can face. When the Avengers learn of this, they travel to the wizarding world to find Harry. They rescue him from an immediate threat so that they can all prepare to face this greater danger together. The Avengers could introduce new ways of fighting and thinking to Harry, while Harry could share his knowledge of magic with them.
Raven could be integrated by having a common enemy. Let's say there's a powerful being that wants to conquer both the magical world of Harry Potter and the superhero - filled world of the Avengers. Raven, with her own set of powers that combine elements from both worlds, is the key to stopping this enemy. In the Harry Potter side, she could teach the students some new ways of combat magic that she learned from her experiences in the Avengers' world. And in the Avengers world, she could use her knowledge of Hogwarts' magic to create new defenses against threats that are related to magic.
