Harry would likely be both curious and cautious when interacting with Death. He might ask Death many questions about the meaning of life and death in the wizarding world. Other characters like Hermione and Ron, if they are involved, would probably be very worried about Harry's interaction with Death and try to protect him or convince him to stay away.
If we consider Dumbledore's spirit to be present in this fanfic, he might act as a mediator between Harry and Death. Dumbledore, with his great wisdom, could help Harry understand Death's motives and intentions. Meanwhile, Death might be amused or intrigued by the relationships between these characters. It could play with their emotions and beliefs, for instance, by making them question their past actions related to life and death situations.
The interaction could also involve some of the dark wizards or Death Eaters. They might see Death's appearance as an opportunity to gain more power. Death, on the other hand, might toy with them, leading them to believe they can get what they want only to show them the futility of their desires. And Harry would be caught in the middle, trying to stop the dark wizards from making a deal with Death that could have disastrous consequences for the wizarding world.
Hermione would probably try to understand Shendu from a logical and magical perspective. She could attempt to communicate with him to find out more about his powers and his weaknesses. Ron, on the other hand, would be more likely to jump into action if he saw Shendu as a threat. He might not be as diplomatic as Hermione and could end up getting into a scuffle with Shendu's minions. The three of them together would have to figure out how to deal with Shendu's different approach to magic compared to what they're used to in the wizarding world.
Harry would probably be a bit shy at first when meeting the Avengers. But he would soon start sharing his knowledge of magic. The Avengers might be curious and ask a lot of questions. For instance, Tony Stark would be eager to understand the principles behind magic.
In a 'Harry Potter meets Apollo' fanfiction, their interaction would be quite complex. For starters, Dumbledore would surely approach Apollo with great respect, being aware of the power and significance of a god. Apollo might be interested in Dumbledore's wisdom and magic. The students, like Neville, could look up to Apollo as a new source of strength. Meanwhile, Apollo might see the potential in these young wizards and witches and decide to mentor them in some ways, sharing his knowledge of combat and strategy from his long existence in Greek mythology.
The Stargate characters are used to dealing with advanced technology and alien cultures. When they meet the Harry Potter characters, they might be initially confused by magic. For example, Jack O'Neill might be both amused and intrigued by the spells the wizards cast. Meanwhile, Harry Potter and his friends would be curious about the Stargate technology and the different worlds it can access.
The characters would interact in very strange ways. The Hogwarts students would be shocked by the Jackass crew's behavior. The Gryffindors might be initially intrigued, while the Slytherins would be disdainful. Harry and his friends would probably try to keep the Jackass guys out of trouble, but it would be difficult as they are always looking for the next wild thing to do.
Harry might be in awe of Elsa's powers at first. He would likely approach her with caution and respect, as he does with most powerful beings. Elsa, on the other hand, would be curious about Harry's world of wands and spells. They could start by sharing their stories. Harry would talk about Voldemort and his battles, and Elsa would share her experiences with her frozen kingdom and her isolation.
The Ouran characters, who are used to a world of wealth and social hierarchies, would be introduced to Harry's world of magic and death. Haruhi, being the most down - to - earth among them, might be the first to understand Harry's situation. She could help him adapt to the Ouran school while Harry could show her the power of magic. Other characters like the twins might be more interested in using Harry's magic for mischief.
The characters' interactions could be really complex. Hermione would be eager to study the Avengers and their powers from a scientific and magical perspective. She might try to find parallels between magic spells and the Avengers' abilities. Captain America would respect the values of the wizarding world like loyalty and courage which are similar to his own. The Master of Death could play a role in bringing out the best in both groups. He could encourage Harry Potter to be more bold in his actions like the Avengers, and also teach the Avengers about the subtleties of magic. For instance, how a simple spell can have a profound impact on the world around them.
Imagine Harry Potter, who has faced Voldemort and death so many times, meeting the Arcobaleno. He would bring his own set of values and beliefs, like the importance of friendship and loyalty. The Arcobaleno, who have their own complex relationships, would either resonate with or be challenged by Harry's ideas. Their interactions could range from serious discussions about the nature of death and power, to light - hearted exchanges about the quirks of their respective magical items. Harry might even use his invisibility cloak to play pranks on the Arcobaleno, just like he did at Hogwarts, which could lead to some comical and endearing moments in the fanfiction.
Hermione would likely be very curious about Anastasia. She might study her as if she were a new and interesting magical creature. Hermione would probably ask Anastasia a million questions about her Muggle life and try to understand how she thinks.
