If Harry Potter was captured by the Avengers in fanfiction, he might try to communicate with them first. If that doesn't work, he could use some powerful spells. He could cast the Imperius Curse on one of the less - resistant Avengers to help him escape. Or he could use a Time - Turner if he had one, to go back in time a bit and avoid the capture altogether. Another option is to use his Patronus. The bright and powerful Patronus might blind the Avengers momentarily, giving him time to escape.
Harry could use his magic skills cleverly. For instance, he could create a diversion with a bunch of conjured creatures like doxies or Blast - Ended Skrewts. While the Avengers are distracted, he could use a spell to unlock his restraints and then make a run for it. He might also use his Occlumency skills to block any mind - reading attempts from telepathic Avengers like Scarlet Witch, so they can't anticipate his moves.
He could use his Invisibility Cloak. The Avengers might not be able to detect it with their technology. Then he could find a way to apparate out if he's far enough from any anti - apparition charms.
Harry could use a powerful disillusionment charm. This would make him blend in with his surroundings so well that SHIELD agents would have a hard time finding him. He could then make his way to an exit while they're distracted. Also, if he had his wand on him, he could perform a series of diversionary spells, like creating a false image of himself to draw their attention away while he escapes.
Percy could use his water powers. He could summon water from nearby sources, like pipes or even the air if it's humid enough. With the water, he could create distractions, like water walls or waves to disorient the Avengers. Then he could make a run for it.
The Avengers' reaction would be a mix of caution and curiosity. Hawkeye might keep his arrow aimed at Harry, ready for any sudden moves. Black Widow would be using her skills to read Harry's body language and try to figure out if he's lying. The Hulk might be held back initially, but if Harry made any sudden or 'threatening' moves, things could get really hairy. Overall, they'd all be on high alert until they understood that Harry was not an enemy but a young wizard with his own set of skills and a good heart.
Percy might try to find Voldemort's Horcruxes and destroy them. This would weaken Voldemort and give Percy a better chance to escape. He could also use his demigod speed and agility to outrun Voldemort's spells and find a way out of the dark wizard's lair.
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, in a fanfiction scenario, if Harry Potter was captured by the Avengers, there could be a lot of confusion at first. The Avengers might think he's a new kind of threat from another dimension. Harry, on the other hand, would be really bewildered by all the high - tech gadgets around him. He'd probably try to use his magic, which would shock the Avengers. Maybe Iron Man would be the first to try and analyze his magic, while Captain America would be more cautious and try to communicate with Harry.
In such a fanfiction scenario where Harry Potter is captured by the Avengers, initially there would be a lot of confusion. The Avengers, being protectors of Earth, might see Harry's magic as something dangerous and unregulated. However, once they start to communicate, they could find common ground. Harry could show them how magic has been used for good in his world, and the Avengers could introduce Harry to the concept of superhero teamwork on a large scale. It could be a really interesting crossover story.
First, they would need to figure out if it was a trap. But assuming it's not, they could divide into teams. One team, like Ant - Man and Wasp, could infiltrate the place in a stealthy way. Meanwhile, Doctor Strange could use his magic to create illusions and misdirect the captors. The Avengers would have to work together, combining their different powers and strategies to rescue Natasha successfully.
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.
