There would be a wide range of reactions. The more violent inmates could immediately lash out at Harry, seeing him as an easy target. However, some of the inmates who have a bit more of a moral compass might be curious about his motives. They might wonder if he's there to help them or if he has some other purpose. Harry's presence would disrupt the normal power dynamics in the asylum, causing a lot of unrest and speculation among the inmates.
The more intelligent inmates, like the Joker if he were there, might be intrigued by Harry. They would want to figure out how his magic works and might try to use it for their own devious plans. Others might see him as a savior, someone who could get them out of the asylum with his magic.
Well, he'd probably be exposed to a lot of chaos and madness. He might develop some very different magical skills, perhaps ones influenced by the dark and deranged atmosphere of Arkham. He could also have a very warped view of the wizarding world compared to what we know from the original series.
His magic might be darker. The environment of Arkham Asylum is full of negative energy. So, it could taint his magic in some way, making it more aggressive or unpredictable.
In such a fanfiction, Harry Potter could bring a new perspective to Arkham Asylum. He has faced dark wizards and dark magic, so he might see similarities in the deranged minds of the asylum's inmates. His Gryffindor courage would lead him to explore the place, perhaps making unexpected alliances with some of the more misunderstood inmates, all while trying to keep his magical identity a secret to avoid chaos.
He could be shocked. Maybe there are some fanfictions that take a very dark turn or have unexpected pairings that he never thought of. He'd probably need some time to process such strange ideas. And he might also be curious to see how far the creativity of the fans can go. He might even get some new ideas about his own life from reading some of the more imaginative fanfictions.
A 'naruto in arkham asylum fanfiction' would likely involve Naruto being transported to the Arkham Asylum universe. He would be confused at first, but then quickly adapt. His chakra abilities would seem like magic to the inmates and staff. He might try to find a way to get back home while also getting involved in the internal power struggles within the asylum.
Hermione, on the other hand, would likely have a more critical view. She'd analyze the fanfictions for their accuracy in terms of magic lore and Hogwarts traditions. If there were any inaccuracies, she'd be quite perturbed. However, she might also appreciate the creativity that goes into some of the well - written ones that add new dimensions to their magical world.
He might be amused. Harry has a sense of humor, and the often absurd and comical situations in Blackadder fanfiction could make him laugh.
There's a chance he'd be inspired. The stories of the Naruto characters' determination and growth in the fanfiction could stir something in him. He might think about his own journey as a wizard and how he can further develop his skills and character, taking cues from the Naruto characters' tenacity.
In this fanfiction, the interactions would be full of tension. Harry would be like a fish out of water in Arkham. The villains in Arkham, such as the Joker or Harley Quinn, could have very different reactions to Harry. The Joker might see him as a new plaything to toy with, while Harley Quinn might show some sympathy towards him. And Harry would have to constantly navigate these dangerous relationships while also trying to figure out his own identity in this strange new world.
At the beginning, Harry would be frightened. He's in an unknown place with Loki, who is known for his trickery. But Harry is no pushover. He would quickly gather his courage. He would remember all the times he's faced danger at Hogwarts. He might try to communicate with Loki to understand his motives. If Loki reveals that he wants to use Harry's magic for something, Harry would try to find a way to outsmart Loki. He could pretend to cooperate while actually looking for a weakness in Loki's plan. Harry would also be thinking about his friends at Hogwarts and how he needs to get back to them, which would give him extra motivation to fight back against Loki.
